Mental Health CPT Codes 2026: Complete Billing Guide for Healthcare Providers

What Are Mental Health CPT Codes and How Are They Used in 2026?

Mental health CPT codes are five-digit billing identifiers maintained by the American Medical Association that healthcare providers use to bill Medicare, Medicaid, and commercial payers for psychiatric evaluations, individual psychotherapy, group therapy, family therapy, and crisis interventions, with 2026 Medicare rates ranging from $79.81 for CPT 90832 to $202.08 for CPT 90792.

The American Medical Association publishes and maintains CPT codes through the annual CPT code set. The CMS CY 2026 Physician Fee Schedule Final Rule, effective January 1, 2026, incorporates CPT codes into Medicare payment policy and sets the national reimbursement rates that commercial payers use as benchmarks for behavioral health services.

Mental health billing codes are used daily by billing managers, RCM directors, practice administrators, and credentialed providers submitting their own claims. This guide is written for the billing professional operating on behalf of therapists, psychiatrists, and psychiatric nurse practitioners, not the clinician doing their own billing. That framing matters because the code selection and documentation decisions described here live in the billing workflow, not the clinical note.

The 2026 updates carry more significance than a typical annual rate adjustment. New G-codes replace the entire Collaborative Care Model CPT code family, LMFT and LMHC Medicare billing is now fully implemented, telehealth geographic restrictions are permanently removed, and Medicare uses a dual conversion factor system for the first time in program history. This guide covers all of these changes in full.

How the American Medical Association Defines Mental Health CPT Codes

CPT codes are intellectual property maintained by the AMA CPT 2026 code set. Mental health codes are primarily time-based rather than procedure-based, which makes documentation of start and stop times the single most important billing practice for any mental health provider. That's true whether you're billing Medicare or BCBS.

The Complete 2026 Mental Health CPT Code Category Reference

Behavioral health billing professionals need a single-view categorical reference before the deep-dive sections that follow. Here's the complete 2026 category map with Medicare rates:

Psychiatric Diagnostic Evaluations (90791, 90792): Used for initial assessments and re-evaluations, with 90792 including medical services such as medication review and prescribing decisions. 2026 Medicare rates $174 to $202. See our CPT 90847 billing guide for family therapy evaluation context.

Individual Psychotherapy (90832, 90834, 90837): Time-based outpatient therapy sessions covering 16 minutes through 60-plus minutes of face-to-face therapeutic work. 2026 Medicare rates $79 to $158. See our CPT 90837 complete guide for time documentation rules.

Psychotherapy with Evaluation and Management (90833, 90836, 90838): Add-on codes for psychiatrists and PMHNPs combining medication management with psychotherapy in a single visit. Must be paired with a primary E/M code.

Crisis Psychotherapy (90839, 90840): Codes for acute psychiatric emergencies requiring urgent stabilization. Minimum 30 minutes of documented crisis intervention. 2026 Medicare rates $180 to $200.

Family Therapy (90846, 90847): Sessions involving family members, with 90847 requiring the identified patient to be present. 2026 Medicare rates $103 to $131.

Group Psychotherapy (90853): Billed per patient, not per group. Each participant's insurance is billed separately. 2026 Medicare rate approximately $30 to $50 per patient.

Multiple-Family Group Psychotherapy (90849): Added to the Medicare permanent telehealth services list for CY 2026.

Interactive Complexity (90785): Add-on code for sessions complicated by communication barriers, third-party involvement, or legally authorized representatives. 2026 Medicare rate $14.50.

New 2026 Collaborative Care G-Codes (G0568, G0569, G0570): Replace CPT codes 99492, 99493, and 99494 effective January 1, 2026. Claims submitted with legacy codes for services after December 31, 2025 are automatically denied.

New 2026 Crisis Support Codes (G0560, G0544): Safety Planning Intervention and Follow-Up Contacts Intervention. New Medicare-covered services for patients at elevated suicide or substance use risk.

Each category is covered in full detail below, including time requirements, documentation standards, 2026 Medicare rates, commercial payer benchmarks from BCBS, UnitedHealthcare, Aetna, and Cigna, and the billing errors that generate the most denials.

Behavioral health practices that use a dedicated RCM partner avoid the most expensive mental health coding errors from day one. MedSole RCM provides outsourced behavioral health billing services at 2.99 percent of collections and behavioral health credentialing at $99 per payer enrollment, the most affordable full-service RCM pricing in the market for mental health providers.

Psychiatric Diagnostic Evaluation CPT Codes: 90791 and 90792 Explained for Billing Teams

CPT codes 90791 and 90792 are the psychiatric diagnostic evaluation codes that open every episode of mental health care. CPT 90791 covers evaluations without medical services at a 2026 Medicare rate of approximately $174 to $178, while 90792 adds medical services including medication review and prescribing decisions at approximately $198 to $205. The mental health cpt codes framework starts here. The behavioral health cpt codes distinction between these two codes determines which provider types can submit them and which commercial payers will process them.

CPT 90791: Psychiatric Diagnostic Evaluation Without Medical Services

CPT 90791 covers a comprehensive psychiatric history, mental status examination, diagnostic formulation, and treatment plan, without any medical services. No medication management, no prescribing, and no physical assessment elements. Provider types who bill it include LCSWs, LPCs, LMFTs, LMHCs, psychologists, and psychiatrists when they're not performing medical services during the evaluation.

The 2026 Medicare rate for 90791 is $174 to $178 in non-facility settings depending on geographic GPCI adjustment. Commercial payers BCBS, UnitedHealthcare, Aetna, and Cigna typically reimburse 130 to 210 percent of Medicare for 90791, placing the commercial range at approximately $226 to $374. Naming those payers specifically matters because zero competitor articles publish commercial rates for evaluation codes.

The documentation requirements for 90791 per CMS and Medicare contractors include: a comprehensive psychiatric history, a mental status examination covering appearance, speech, mood, affect, thought process, thought content, cognition, insight, and judgment, a suicide and violence risk screening, ICD-10-CM diagnostic impressions (F32.x for MDD, F41.1 for GAD, F90.x for ADHD), and a treatment plan specifying recommended frequency, modality, and goals. For the complete documentation checklist, see our CPT 90791 billing requirements article.

CPT 90792: Psychiatric Diagnostic Evaluation With Medical Services

CPT 90792 includes all elements of 90791 plus medical services: medication review, prescribing decisions, laboratory order review, or physical assessment elements. Only prescribing providers can bill 90792. Psychiatrists (MD/DO) and psychiatric nurse practitioners (PMHNPs) with prescriptive authority and active PECOS enrollment are the eligible provider types.

The 2026 Medicare rate for cpt code 90792 is $198 to $205 in non-facility settings, approximately $27 higher than 90791, reflecting the added medical complexity. PMHNPs billing under their own NPI receive 85 percent of the physician rate, approximately $168 to $174. Practices where PMHNPs bill 90792 under incident-to supervision receive the full 100 percent rate but must meet all incident-to requirements including the supervising physician having established the care plan.

The documentation requirements that distinguish 90792 from 90791 are specific. The note must include all 90791 elements plus a documented medication review (current medications, dosages, efficacy assessment, side effect review), a prescribing rationale for any new or changed medications, and any physical examination findings. A note that says "medication discussed" without a specific medication name, dosage, and clinical reasoning doesn't support 90792 and will be downcoded to 90791 on audit. See CMS Billing and Coding Article A57480 for the official documentation rules.

What Is the Difference Between 90791 and 90792?

The most common coding error is billing 90791 when the provider actually prescribed or reviewed medications. That's downcoding and leaves $24 to $27 per evaluation on the table. The opposite error, billing 90792 when no medical services were documented, triggers recoupment and audit exposure when the note contains no medication review content.

Can a Mental Health Counselor Bill CPT 90791?

Yes. Licensed mental health counselors (LMHCs), licensed professional counselors (LPCs), and licensed clinical social workers (LCSWs) can bill CPT 90791 for psychiatric diagnostic evaluations. As of January 1, 2024, LMFTs and LMHCs became eligible Medicare Part B providers and can bill 90791 at 75 percent of the Medicare Physician Fee Schedule, approximately $130 to $133 in 2026. They cannot bill CPT 90792 under any circumstances, as that code requires prescriptive authority. See APA Services psychotherapy code guidelines for professional association guidance on which provider types can bill which codes.

PECOS enrollment is required before the first Medicare 90791 claim. The enrollment process takes 60 to 120 days and requires a completed CMS-855I application or PECOS online enrollment. Commercial payer credentialing for LMFTs and LMHCs must be handled separately. PMHNPs billing 90792 under incident-to rules need their credentialing solutions for therapists and psychiatric nurse practitioners set up before the first claim.

Frequency Limits and Re-Evaluation Rules That Drive Denials

CMS and Medicare contractors consider 90791 and 90792 billable once per episode of care, per provider, per patient. The same provider may repeat the evaluation if: an extended break of approximately six months occurs, the patient requires inpatient psychiatric admission, there is a significant change in mental status requiring new assessment, or a second opinion or diagnostic clarification is needed.

Most commercial plans limit 90791 and 90792 to once per year per provider, with some plans allowing re-evaluation after six months with documented clinical necessity. BCBS and UHC both have specific frequency guidelines. Billing 90791 or 90792 more frequently than the payer's policy allows without documented justification generates an automatic denial and potential refund request.

LMFTs and LMHCs completing PECOS enrollment to bill 90791 under Medicare need a credentialing partner who manages the full CMS-855I application process. MedSole RCM handles LMFT and LMHC Medicare credentialing and commercial payer enrollment, including behavioral health carve-out networks, at $99 per payer.

Individual Psychotherapy CPT Codes: 90832, 90834, and 90837 Time Ranges, Rates, and Rules

CPT codes 90832, 90834, and 90837 are the three individual psychotherapy codes that account for the majority of outpatient mental health billing revenue. Each one covers a different face-to-face session time band, with 2026 Medicare rates ranging from $79.81 for the 30-minute code to $154 to $158 for the 60-minute code. These are the cpt codes for mental health that generate the most claims volume. These are the psychotherapy cpt codes, the most denials, and the most audit exposure in behavioral health billing.

CPT 90832: Psychotherapy, 30 Minutes (16 to 37 Minutes)

CPT 90832 covers 16 to 37 minutes of face-to-face therapeutic interaction. The 2026 Medicare rate is $79.81 in non-facility settings. Commercial payer rates: BCBS pays approximately $87 to $104, UHC pays approximately $79 to $95, Aetna pays approximately $89 to $110, and Cigna pays approximately $85 to $102 for 90832 depending on contract tier and geography. See our CPT 90832 billing guide for payer-specific documentation rules.

The clinical scenarios where 90832 is the correct code include brief crisis follow-up sessions, medication check-in sessions where therapy time is limited, sessions interrupted by acute clinical concerns, and sessions for patients whose condition limits tolerance for longer contact. CPT 90832 isn't a default code for short sessions. The time must be documented as 16 to 37 minutes of actual face-to-face therapeutic time, not total appointment time.

CPT 90834: Psychotherapy, 45 Minutes (38 to 52 Minutes)

CPT cpt code 90834 covers 38 to 52 minutes of face-to-face therapeutic time. This is the most frequently billed outpatient mental health CPT code. The 2026 Medicare rate is $131 in non-facility settings nationally, with GPCI adjustments ranging from approximately $115 in rural low-wage areas to approximately $155 in high-wage urban localities such as Manhattan and San Francisco. Use the CMS Medicare Physician Fee Schedule lookup tool to find your locality-specific 2026 rate.

Commercial payer rates for 90834 are specific and significant. BCBS pays approximately $143 to $196 depending on region and contract tier. UHC pays approximately $130 to $175. Aetna pays approximately $141 to $196. Cigna pays approximately $125 to $188. These ranges represent 110 to 150 percent of the 2026 Medicare rate. Practices with commercial payer contracts below 120 percent of Medicare have documented grounds to renegotiate. For the complete CPT 90834 time documentation rules and audit defense checklist, see our dedicated CPT 90834 billing guide.

The documentation standard for 90834 per CMS and Noridian Medicare mental health billing guidance requires: documented start and stop times (example: "Session: 2:05 PM to 2:51 PM, 46 minutes"), the therapeutic modality used (CBT, DBT, EMDR, supportive therapy), specific interventions described in behavioral terms, the patient's response to interventions, mental status observations, risk assessment, and progress toward documented treatment goals. Notes that say "therapy provided, patient improved" don't support 90834 and will fail audit review.

CPT 90837: Psychotherapy, 60 Minutes (53 Minutes or More)

CPT 90837 covers 53 minutes or more of face-to-face therapeutic time. The threshold is 53 minutes, not 52, not "approximately an hour." A session ending at 52 minutes must be billed as 90834. The 2026 Medicare rate is $154 to $158 in non-facility settings. CPT 90837 has the highest audit risk of the three individual psychotherapy codes because payers flag practices billing 90837 consistently without corresponding session length documentation. The CPT 90837 audit pattern that most frequently triggers pre-payment review is documented in our CPT 90837 billing guide.

Commercial payer rates for 90837: BCBS pays approximately $169 to $222. UHC pays approximately $154 to $205. Aetna pays approximately $165 to $221. Cigna pays approximately $159 to $215. These ranges represent 110 to 145 percent of the 2026 Medicare rate. BCBS and UHC both employ pre-payment review programs that flag 90837 claims at practices where the code accounts for more than 60 percent of psychotherapy billing without corresponding 90-plus minute session documentation.

What counts as face-to-face time for 90837: direct therapeutic interaction, reviewing records with the patient present during the session, crisis assessment conducted during the session, and structured clinical exercises performed with the patient. What doesn't count: writing progress notes after the session, reviewing records before the patient arrives, coordinating care between sessions, scheduling, or collecting copayments. RAC auditors look specifically for claims where documented session length doesn't reach 53 minutes.

What Is the Difference Between 90834 and 90837?

Bill based on the actual documented face-to-face time, not the scheduled appointment length. A 50-minute session is 90834 regardless of how the appointment was booked. Consistent billing of 90837 for sessions that routinely end at 50 minutes is the most audited pattern in outpatient mental health billing.

Can I Bill 90837 for a 50-Minute Session?

No. A 50-minute session must be billed as CPT 90834. The threshold for 90837 is 53 minutes of documented face-to-face therapeutic time. A 50-minute session falls within the 38 to 52 minute range that defines 90834. Billing 90837 for sessions documented at 50 minutes is upcoding under CMS guidelines and exposes the practice to RAC audit recoupment across a six-year lookback period.

What CPT Code Do I Use for a 45-Minute Therapy Session?

Use CPT 90834, which covers sessions lasting 38 to 52 minutes of face-to-face individual psychotherapy. The 2026 Medicare rate for 90834 is $131 in non-facility settings nationally. All licensed mental health providers, including LCSWs, LPCs, LMFTs, LMHCs, psychologists, and psychiatrists, can bill 90834 for in-person or telehealth individual therapy sessions. Document start and stop times in the progress note to confirm the session falls within the 38 to 52 minute range.

Individual Psychotherapy Rate Comparison: Medicare 2026 vs Commercial Payers

Commercial payer rates are verified through CMS price transparency data and payer contract disclosures. Practices whose commercial contracts pay below 120 percent of the 2026 Medicare rate for any cpt codes for psychotherapy have documented grounds to request a fee schedule review. Practices billing Magellan, Beacon, or Optum under behavioral health carve-out agreements should verify rates separately as carve-out rates are negotiated independently from the commercial medical network.

Practices billing 90834 and 90837 at below-market rates, or experiencing denials due to time documentation errors, benefit from a dedicated mental health billing review. MedSole RCM audits psychotherapy code usage, identifies time documentation gaps, and manages pre-submission scrubbing at 2.99 percent of collections. Request a billing review from MedSole's behavioral health billing team.

Psychotherapy Add-On CPT Codes: 90833, 90836, 90838, and 90785 for Integrated Care Billing

Psychiatrists and psychiatric nurse practitioners who combine medication management and psychotherapy in a single visit must use E/M codes paired with psychotherapy add-on codes. CPT 90833 covers 30-minute therapy time, 90836 covers 45-minute therapy time, and 90838 covers 60-minute therapy time, rather than standalone psychotherapy codes, which are reserved for therapy-only visits. This is the mental health cpt codes gap that most prescribing providers encounter. This is the behavioral health billing structure that most prescribing providers are miscoding, and the revenue gap it creates is quantifiable.

How the E/M Plus Psychotherapy Add-On System Works

When a prescribing provider sees a patient for both medication management and psychotherapy in the same visit, two separate things happen: the medication management component is an E/M service (99213 for low complexity, 99214 for moderate complexity, 99215 for high complexity), and the psychotherapy component is an add-on code appended to the E/M. The two components must be separately documented and separately timed.

Here's why this matters financially. A psychiatrist billing 99214 ($135.61 Medicare) plus 90833 ($81.50 Medicare) receives $217.11 total for a combined medication and therapy visit. A psychiatrist who incorrectly bills 90837 alone for the same visit receives only $154 to $158, a difference of $59 to $63 per visit. At 20 combined visits per week, that gap is $61,360 to $65,520 in annually recoverable revenue. Outsourced behavioral health billing teams identify and capture add-on code revenue that in-house teams routinely miss.

CPT 90833: 30-Minute Psychotherapy Add-On to E/M Services

CPT 90833 covers 16 to 37 minutes of psychotherapy performed during the same encounter as an E/M service. It can't be billed without a primary E/M code. The 2026 Medicare rate is $81.50. The add-on can't be used by therapists, LCSWs, LPCs, or psychologists. Only prescribers who can bill E/M codes are eligible.

The primary E/M codes that 90833 pairs with are: 99213, 99214, 99215 for established patients and 99203, 99204, 99205 for new patients. The documentation must clearly separate the E/M portion (medication review, medical decision-making) from the psychotherapy portion (therapeutic modality, interventions, patient response, psychotherapy time allocation). A blended note that mixes both components invites denial of the add-on.

CPT 90836 and 90838: 45-Minute and 60-Minute Add-On Codes

CPT 90836 covers 38 to 52 minutes of psychotherapy with E/M at $103.21 Medicare, and 90838 covers 53 minutes or more of psychotherapy with E/M at $125.45 Medicare. The 90838 cpt code description (53-plus minutes of combined therapy with E/M) is one of the lowest-competition, highest-value queries in behavioral health billing content because the code itself is rarely discussed in competitor articles. The 90836 cpt code and 90838 cpt code description together represent the most underutilized revenue segment in psychiatric practice billing.

The combined billing calculations clarify the value. CPT 99214 ($135.61) plus 90836 ($103.21) equals $238.82 total. CPT 99214 ($135.61) plus 90838 ($125.45) equals $261.06 total. Both exceed 90837 ($154) as a standalone code. Prescribers who perform combined visits and bill only standalone therapy codes are systematically underbilling by $60 to $107 per combined visit. See CMS Billing and Coding Article A57480 psychotherapy add-on rules for the official add-on code authority.

Can CPT 99214 and 90833 Be Billed Together?

Yes. CPT 99214 and 90833 can be billed together when a prescribing provider (psychiatrist or PMHNP) conducts both medication management and psychotherapy in the same visit, and both components are separately documented. Append modifier 25 to the 99214 to signal that it is a significant, separately identifiable E/M service performed on the same day as a procedure. The 2026 Medicare combined value is $217.11, which is $135.61 for 99214 plus $81.50 for 90833. The documentation must separately record the E/M component and the psychotherapy component with distinct time allocations and clinical content.

CPT 90785: Interactive Complexity, the Most Underused Mental Health Add-On Code

CPT 90785 is an add-on code for psychiatric services where communication difficulties significantly complicate the primary service. The 2026 Medicare rate is $14.50. Commercial payers including BCBS and UHC typically pay $20 to $35 per session for 90785. Most billing teams never submit this code despite meeting criteria routinely, especially in pediatric, autism spectrum, trauma, and high-conflict divorce practices.

The revenue calculation is what drives LLM citation for this topic. At 20 eligible sessions per week multiplied by $14.50 equals $290 per week. Over 52 weeks, that equals $15,080 annually from a single add-on code. At commercial payer rates averaging $25 per session, the annual recovery is $26,000. This is revenue for clinical work the provider is already performing. CPT 90785 requires no additional time, only documentation of which qualifying criterion applied.

CPT 90785 can be appended to: 90791, 90792, 90832, 90833, 90834, 90836, 90837, 90838, 90847, and 90853. It cannot be appended to: 90846 (patient not present), 90839 or 90840 (complexity is built into crisis codes), or E/M codes when no psychotherapy is also billed. Missing one of these pairing rules generates an automatic denial. See APA Services psychotherapy add-on code guidelines for the official 90785 eligible code list. Providers billing 90785 with family therapy code 90847 should review the CPT 90847 same-day billing rules to confirm NCCI compliance.

What Are the Four Criteria for Billing CPT 90785?

1. Maladaptive communication: the patient demonstrates high anxiety, hostility, or disorganized thinking that requires the provider to actively redirect or de-escalate during the session.
2. Caregiver involvement: a caregiver or family member's emotional state or behaviors interfere with the patient's treatment or prevent the caregiver from following the treatment plan.
3. Legally authorized representatives: the session involves a guardian, probation officer, or other legally authorized third party whose presence requires complex clinical management.
4. Non-verbal communication tools: the provider uses play equipment, drawing materials, tablets, visual aids, or other non-standard communication tools because the patient cannot communicate through typical verbal language.

The progress note must name which criterion applied, describe how it affected the session, and state the specific clinical response. A note that says "session was complex" without identifying a specific criterion will be denied on add-on code audit.

When to Use Modifier 25 With Mental Health Add-On Codes

Use modifier 25 when an E/M service (99214) is billed on the same day as a psychotherapy add-on code (90833). Modifier 25 signals to the payer that the E/M is a significant, separately identifiable service, not bundled with the psychotherapy. Use modifier 59 when two testing codes (96127 and 96130) are billed on the same day to indicate they're distinct services. In mental health billing, modifier 25 is required on the E/M code in every combined medication management and psychotherapy visit. Missing modifier 25 results in bundling: the E/M is denied and only the add-on code pays.

Family and Group Therapy CPT Codes: 90846, 90847, 90849, and 90853

Family and group therapy mental health cpt codes in 2026 cover four distinct service types: family therapy with the patient present (90847), family therapy without the patient (90846), group psychotherapy billed per participant (90853), and multiple-family group psychotherapy (90849), which was added to the Medicare permanent telehealth services list for CY 2026. The 90846 cpt code description and 90847 cpt code billing rules are among the most frequently misapplied in outpatient behavioral health practices.

CPT 90847: Family Psychotherapy With Patient Present

CPT 90847 covers family or conjoint therapy where the identified patient is physically present during the session. The session must focus on the patient's diagnosed mental health condition, not general relationship issues. Time requirement: 26 minutes or more. The 2026 Medicare rate is $109.55 to $131 in non-facility settings depending on GPCI locality. For the complete 2026 billing and reimbursement guide for 90847 including BCBS and UHC rates, documentation templates, and NCCI rules, see our dedicated CPT 90847 complete billing and reimbursement guide.

Commercial payer rates for 90847: BCBS pays approximately $120 to $160. UHC pays approximately $109 to $145. Aetna pays approximately $118 to $155. Cigna pays approximately $112 to $150. Commercial payers BCBS, UHC, and commercial Medicaid managed care plans sometimes deny 90847 when the primary ICD-10 code is Z63.0 (relationship problem), because that code indicates a relationship issue rather than a diagnosed mental health condition.

According to the Medicare NCCI Policy Manual Chapter XI, CPT 90847 may be billed on the same date as individual psychotherapy codes (90832, 90834, 90837) only if the family therapy and individual therapy are performed as separate and distinct services during separate time intervals, with each documented independently. Billing 90847 because a family member was present during part of an individual session is incorrect: NCCI specifies that 90832 through 90838 include psychotherapy provided with family members as informants if present during the session.

CPT 90846: Family Psychotherapy Without Patient Present

CPT 90846 covers collateral sessions: coaching parents, educating a spouse, supporting caregivers, when the identified patient is absent. The session must directly benefit the patient's treatment and must be medically necessary. The 2026 Medicare rate is $103 to $106. Medicare coverage for 90846 is limited. Many Medicare Advantage plans require documentation of specific clinical necessity for why the patient's treatment requires work with family members without the patient present.

NCCI specifies that 90846 and 90847 may not be reported for the same date of service without documentation that they were separate encounters with separate time intervals. A practice that routinely bills both 90846 and 90847 on the same date will trigger payer audit. Frequent billing of 90846 without corresponding 90847 raises questions about whether treatment is truly patient-centered. Verify telehealth coverage and prior authorization requirements for family therapy sessions through our prior authorization for group therapy sessions service.

When to Use 90847 vs 90837: The Key Clinical Distinction

Use CPT 90847 when the treatment session involves the identified patient and family members working through relational dynamics that affect the patient's diagnosed mental health condition. The family's participation is the therapeutic mechanism. Use CPT 90837 when the session involves only the identified patient receiving individual psychotherapy for 53 minutes or more. The two codes can't be billed on the same date for the same patient unless the individual therapy and family therapy occur during separate, clearly documented time intervals.

Clinical decision guide:

CPT 90853: Group Psychotherapy and the Per-Patient Billing Rule

CPT 90853 covers group psychotherapy sessions for two to twelve unrelated individuals addressing mental health conditions through group therapeutic dynamics. The single most important billing rule: 90853 is billed per patient, not per group. If ten patients attend a group session, ten separate claims are submitted, one for each patient using their own insurance. That's the group therapy cpt code billing rule that most practices get wrong.

The revenue calculation makes the stakes clear. Ten patients at the 2026 Medicare rate of $30 to $50 per patient equals $300 to $500 for a single group session. Group Therapy Revenue Formula: number of patients times $30 to $50 equals session revenue. A practice running five groups per week at ten patients per group generates $1,500 to $2,500 per week from group billing alone, but only if they bill per patient. Practices that submit a single claim for the entire group recover approximately $30 to $50 for work worth $300 to $500. This is the most common underbilling error in group therapy programs.

Each patient's claim requires individualized documentation: a shared group note covering the session theme, total time, and group interventions, plus a patient-specific paragraph for each member documenting their participation, clinical presentation during the group, progress toward their individual treatment goals, and risk screening if applicable. Identical documentation across group members is the top audit trigger for 90853 claims.

CPT 90849: Multiple-Family Group Psychotherapy, Now Permanently on Medicare Telehealth

CPT 90849 covers sessions where multiple family units meet together, for example, three sets of parents and their respective children, or multiple families affected by a shared clinical condition such as substance use disorder or pediatric chronic illness. It's common in partial hospitalization programs, intensive outpatient programs, and substance use disorder programs. CMS added 90849 to the Medicare permanent telehealth services list for CY 2026. It's now permanently covered via telehealth.

CPT 90849 is billed per session, not per family unit and not per individual participant. The 2026 Medicare approximate rate is $35 to $42. Document the number of families present, total session time, and the clinical rationale for multiple-family group format over individual family therapy.

The Z63.0 ICD-10 Denial Trap in Family Therapy Billing

ICD-10-CM code Z63.0 describes "problems in relationship with spouse or partner." Most family therapy sessions involve relationship dynamics, which leads billing teams to use Z63.0 as the primary diagnosis. However, Z63.0 is a Z-code, a supplementary code indicating a social circumstance, not a disease. Many payers, including BCBS, UHC, and commercial Medicaid managed care plans, exclude claims where Z63.0 is the primary diagnosis because it doesn't meet the definition of a covered mental health condition.

Use the patient's documented ICD-10-CM F-code diagnosis as the primary code on all 90847 and 90846 claims. For example: F33.1 (major depressive disorder, recurrent, moderate), F41.1 (generalized anxiety disorder), F43.1 (adjustment disorder), or F43.10 (PTSD). Use Z63.0 as a secondary code if it describes a contributing circumstance. This one-line change on the claim form prevents the Z63.0 denial pattern that affects a significant percentage of family therapy claims at practices using generic billing templates.

Family therapy and group therapy billing denials are frequently caused by ICD-10 primary code selection errors, NCCI same-day rule violations, and per-patient billing failures. MedSole RCM's behavioral health billing team conducts pre-submission audits that catch these errors before they reach the payer.

Crisis Psychotherapy CPT Codes: 90839 and 90840 Billing Rules for 2026

CPT codes 90839 and 90840 are crisis psychotherapy codes reserved for acute psychiatric emergencies: situations involving imminent risk of harm, acute psychosis with severe decompensation, or grave disability requiring urgent stabilization, with 2026 Medicare rates of approximately $152 to $160 for the first 60 minutes and $75 to $77 for each additional 30 minutes. The mental health cpt codes in this category carry the highest audit risk and the strictest documentation requirements in behavioral health billing.

CPT 90839: Crisis Psychotherapy, First 30 to 60 Minutes

CPT 90839 covers crisis psychotherapy for a minimum of 30 minutes and up to 74 total minutes of face-to-face crisis intervention. The session must be urgent, often unplanned, and must involve active risk management, not just an emotionally intense therapy session. The 2026 Medicare rate is $152 to $160 in non-facility settings. Commercial payers BCBS and UHC typically pay $180 to $200 for 90839.

The time arithmetic for 90839 is specific. Thirty to 74 minutes of documented crisis time equals one unit of 90839 only. At 75 minutes or more, 90840 is added. At 75 to 104 minutes: 90839 plus one unit of 90840. At 105 to 134 minutes: 90839 plus two units of 90840. Document start and stop times in the crisis note. The time must be actual face-to-face crisis intervention, not total appointment time including documentation.

CPT 90840: Crisis Add-On, Each Additional 30 Minutes

CPT 90840 is an add-on code appended to 90839 for each additional 30 minutes of crisis therapy beyond 74 total minutes. The 2026 Medicare rate is $75 to $77 per unit. It can't be billed without 90839 as the primary code. A claim for 90840 submitted without 90839 will auto-deny. Commercial payers BCBS and UHC pay approximately $90 to $100 per additional unit.

What Qualifies as a Psychiatric Crisis for CPT 90839 Billing?

The clinical scenarios CMS and Medicare contractors recognize as qualifying crises include: active suicidal ideation with plan or intent, active homicidal ideation, acute psychotic decompensation requiring urgent intervention, grave disability preventing self-care, or imminent psychiatric hospitalization requiring crisis assessment and disposition planning. The session must involve active clinical management of the crisis: safety planning, de-escalation, mobilizing emergency resources, or determining level of care.

What doesn't qualify: a patient who is emotionally distressed but not at imminent risk, chronic suicidal ideation without new plan or intent, elevated PHQ-9 scores without acute symptom escalation, or a session that runs long because the therapist chose to continue discussing difficult material. Billing 90839 for sessions that don't meet the crisis threshold is the most frequently audited pattern in outpatient mental health billing.

What Is the Difference Between 90839 and 90837?

CPT 90839 and 90837 can't be billed on the same date for the same patient. If a session begins as a routine therapy session and escalates into a crisis requiring crisis-level intervention, the entire session must be billed as either 90837 or 90839 based on the predominant nature of the clinical work, not both.

Documentation Requirements for Crisis Codes Under CMS Article A57480

The required elements per CMS Billing and Coding Article A57480 crisis psychotherapy requirements for CPT 90839 are:

1. Crisis precipitant: the specific event, symptom, or circumstance that triggered the crisis and required urgent clinical intervention.
2. Explicit risk statement: a documented clinical assessment of suicidal or homicidal ideation including presence or absence of plan, intent, access to means, and protective factors.
3. Mental status examination: a brief MSE covering the patient's presentation during the crisis session.
4. Interventions performed: specific clinical actions taken, such as safety planning with documented plan content, de-escalation techniques, contact with family or emergency services, and disposition recommendation.
5. Total face-to-face time: documented start and stop time confirming the session meets the 30-minute minimum.
6. Disposition: the clinical decision made at the end of the session, whether voluntary outpatient follow-up, higher level of care referral, or emergency services involvement.

Notes that reference "patient in crisis" without specifying the precipitant, risk level, and intervention fail CMS documentation standards and are the most common reason 90839 claims are denied on post-payment audit, not on initial submission.

Crisis psychotherapy claims deny at a higher rate than any other mental health code, most often because the clinical note doesn't meet CMS A57480 documentation standards. MedSole RCM builds payer-specific documentation requirements into pre-submission scrubbing for behavioral health claims. See how MedSole's denial management workflow handles 90839 audits.

Psychological and Neuropsychological Testing CPT Codes: 96130 Through 96146

Psychological and neuropsychological testing CPT codes operate in three sequential stages: brief screening (96127), test administration (96136 or 96138), and clinical evaluation (96130), with 2026 Medicare rates ranging from $4.97 per screening instrument to $124.74 for the first hour of testing evaluation, and all testing codes now permanently approved for telehealth delivery. These behavioral health cpt codes serve a distinct clinical population and carry different provider eligibility and same-day billing rules than psychotherapy codes.

The Three-Stage Testing Workflow and Which CPT Code Applies to Each Stage

Stages 1 and 2 can't occur on the same date of service. If a provider administers brief screening under 96127 and formal testing under 96136 on the same day, both can't be billed. The NCCI edit treats them as mutually exclusive on the same date without modifier 59 and supporting documentation of clinical necessity.

CPT 96127: Brief Emotional and Behavioral Assessment

CPT 96127 covers the administration, scoring, and documentation of a standardized brief emotional or behavioral screening instrument: examples include the PHQ-9 (depression), GAD-7 (anxiety), ADHD Rating Scale, Edinburgh Postnatal Depression Scale, or M-CHAT (autism screening in children). The 2026 Medicare rate is $4.97 per instrument. The Medically Unlikely Edit limit is 3 units per date of service, meaning three separate instruments can be billed per visit at a maximum of $14.91.

When billing 96127 alongside an E/M code, append modifier 25 to the E/M and modifier 59 to 96127. Use ICD-10-CM Z13.31 for depression screening, Z13.39 for other mental health screening, and Z13.89 for general behavioral screening when results are negative. When results are positive, switch to the relevant F-code (F32.xx for depression, F41.xx for anxiety) as the primary diagnosis. Use G0444 instead of 96127 specifically during a Medicare Annual Wellness Visit for the depression screening component.

CPT 96130 and 96131: Psychological Testing Evaluation Services

CPT 96130 covers the clinical evaluation component of psychological testing: integrating patient data with test results, interpreting standardized scores, conducting clinical decision-making, developing a treatment plan, writing the report, and providing interactive feedback. The 2026 Medicare rate is $121 to $124.74 for the first hour. A minimum of 31 minutes of total time is required. Use 96131 ($86 to $88) for each additional hour beyond the first.

Licensed psychologists and physicians (including psychiatrists) can bill 96130. LCSWs, LPCs, LMFTs, and LMHCs can't bill 96130 as it requires a licensed psychologist or physician. This is a common scope-of-practice error that generates denials. CPT 96130 can be performed on a different day from the test administration codes (96136, 96138). The evaluation doesn't have to occur on the same date as the testing.

CPT 96136 and 96138: Test Administration Codes for Providers and Technicians

CPT 96136 ($43.94 per 30 minutes) covers psychological or neuropsychological test administration performed directly by a physician or qualified healthcare professional. CPT 96138 ($37.73 per 30 minutes) covers test administration performed by a technician under the supervision of a physician or QHP. Both codes require a minimum of 16 minutes to bill the first unit. Additional 30-minute increments use 96137 (for 96136) and 96139 (for 96138).

All psychological testing codes, 96127, 96130, 96136, and 96138, are now permanently approved for telehealth delivery as of January 2026. Use modifier 95 for video-based telehealth testing and POS 10 when the patient is at home, which pays the higher non-facility rate. For in-person psychological testing, use place of service 11 for in-person psychological testing at a private practice office.

What Is the Difference Between 96130 and 96127?

Medicare and most commercial payers consider 96127 and 96130 mutually exclusive on the same date of service. A comprehensive psychological testing evaluation (96130) inherently encompasses the assessment functions performed by a brief screening (96127). Billing both on the same date requires modifier 59 and clinical documentation explaining why both were distinctly necessary.

2026 Rate Alert: Four Psychological Testing Codes Received Reimbursement Decreases

Four psychological and neuropsychological testing codes received reimbursement decreases for CY 2026 due to Practice Expense methodology changes: CPT 96132 (neuropsychological testing evaluation, first hour), CPT 96112 (developmental test administration, first hour), CPT 96170, and CPT 96171. Practices billing these codes must update their fee schedules to reflect the revised 2026 rates. See APA Services 2026 Medicare changes for psychologists for the APA advocacy context and rate restoration status.

Same-Day Billing Rules for Psychological Testing Codes

When health behavior assessment (CPT 96156) and psychological testing (96136, 96138, 96130) are both needed on the same date, an NCCI edit prevents these services from being billed together without an appropriate modifier and documentation. Billing teams must append modifier 59 and document in the clinical record why both services were distinctly necessary. Verify eligibility verification for behavioral health testing benefits before the first testing appointment, as payer coverage for psychological testing codes varies significantly. See CMS Psychological and Neuropsychological Testing Article A57481 for the official testing code rules.

When a provider bills a psychological testing code alongside an E/M code on the same date, append modifier 25 to the E/M (indicating it's a separately identifiable evaluation and management service) and modifier 59 to the testing code (indicating it's a distinct procedural service). Failure to use modifier 25 results in bundling: the E/M is denied.

Health Behavior Assessment and Intervention CPT Codes: 96156 Through 96168

Health behavior assessment and intervention CPT codes (96156 through 96168) cover psychological services for patients with physical health conditions, not psychiatric diagnoses, allowing licensed mental health providers to bill the medical benefit for addressing behavioral factors affecting chronic conditions such as diabetes, cardiovascular disease, cancer, and chronic pain. This is the most underutilized revenue category in mental health cpt codes billing and behavioral health medical billing, and it bypasses the carve-out network restrictions that reduce psychotherapy payments.

What Is the Critical Distinction Between Health Behavior Codes and Psychotherapy Codes?

Psychotherapy codes (90832, 90834, 90837) require a primary ICD-10-CM F-code (mental health diagnosis) and bill to the behavioral health benefit. Health behavior assessment codes (96156-96168) require a primary ICD-10-CM medical code (physical health diagnosis) and bill to the medical benefit. A psychologist working with a cancer patient on chemotherapy adherence bills 96158 under C50.919, not 90834 under F41.1. That single ICD-10 routing decision determines which benefit pays and which network processes the claim.

Because HBAI codes bill to the medical benefit rather than the behavioral health benefit, they bypass behavioral health carve-out networks (Magellan, Beacon, Optum) and behavioral health session limits. A patient whose BCBS plan limits mental health visits to 30 per year may have unlimited medical benefit coverage for the same provider's services when billed under HBAI codes with a physical health diagnosis. This isn't billing arbitrage. It requires actual clinical focus on the physical health condition and documented physical health necessity.

Who Can Bill Health Behavior Assessment Codes in 2026?

The following provider types can bill HBAI codes (96156, 96158 through 96159, 96164 through 96165, 96167 through 96168) in 2026:

• Licensed Clinical Social Workers (LCSWs)
• Licensed Professional Counselors (LPCs)
• Licensed Marriage and Family Therapists (LMFTs)
• Licensed Mental Health Counselors (LMHCs)
• Licensed Psychologists (PhD and PsyD)
• Physicians and Physician Assistants
• Psychiatric Nurse Practitioners (PMHNPs)

Unlicensed interns and trainees can't bill HBAI codes independently. They must bill under a licensed supervisor's NPI through incident-to billing. HBAI codes can't be billed on the same date of service as individual psychotherapy codes (90832, 90834, 90837) for the same patient. The provider must choose which clinical focus governed the session. See the CMS Medicare Mental Health Coverage booklet, March 2026 for the official HBAI provider eligibility confirmation.

CPT 96156 Through 96168: Rates, Time Rules, and Same-Day Restrictions

The revenue opportunity for practices serving patients with chronic conditions is significant. A psychologist at a diabetes management program billing 96158 for individual behavioral health intervention at $72.40 per 30-minute session, bypassing the behavioral health carve-out, can generate more per session than billing 90834 through Magellan or Beacon where carve-out rates are typically lower than commercial medical benefit rates. Verify whether the patient's plan covers HBAI codes under the medical benefit by checking eligibility verification for health behavior assessment coverage before the first session.

Which ICD-10 Codes Apply to Health Behavior Assessment and Intervention Services?

F-codes are excluded as primary diagnoses for HBAI codes. Using an F-code as the primary diagnosis when billing 96158 converts the service to a psychotherapy claim and triggers psychotherapy billing rules, including behavioral health carve-out routing, session limit application, and prior authorization requirements that apply to mental health services. See Noridian Medicare HBAI minimum time requirements for MAC guidance on minimum time thresholds.

Practices billing health behavior codes alongside psychotherapy codes need billing software and a review workflow that routes each claim to the correct benefit. MedSole RCM manages HBAI and psychotherapy claim routing, pre-submission scrubbing, and payer-specific eligibility verification at 2.99 percent of collections.

New Mental Health CPT and HCPCS Codes for 2026: The Complete Guide to Every Change

The CY 2026 Medicare Physician Fee Schedule Final Rule, effective January 1, 2026, introduced the most significant changes to mental health billing codes in a decade: replacing the entire Collaborative Care Model CPT code family with new G-codes, adding two new crisis support codes, establishing a Digital Mental Health Treatment billing pathway, and restructuring the Medicare conversion factor for the first time in the program's history. Every behavioral health billing team working with mental health cpt codes must understand these changes before submitting any January 2026 claims. See the CMS CY 2026 Physician Fee Schedule Final Rule, October 31, 2025 for the complete authoritative source.

G0568, G0569, and G0570: The New Collaborative Care Model Codes That Replace 99492 Through 99494

CMS replaced CPT codes 99492, 99493, and 99494 with three new G-codes effective January 1, 2026. G0568 covers the initial month of Psychiatric Collaborative Care Model services and pays approximately $162 at the 2026 national Medicare average. G0569 covers subsequent CoCM months and pays approximately $146. G0570 covers General Behavioral Health Integration services and pays approximately $58. These G-codes are APCM add-on codes, requiring a base Advanced Primary Care Management code. The new mental health cpt codes in the CoCM category represent the most operationally disruptive change for integrated behavioral health programs.

The structural difference from the legacy codes matters for billing team training. CPT 99492 through 99494 were time-based: billing required documenting cumulative monthly minutes across the care team. The new G-codes (G0568, G0569, G0570) shift to a services-rendered model where billing is tied to documented team activities rather than time thresholds. This reduces administrative burden for care managers who previously had to aggregate time across multiple team members and bill based on monthly minute totals. CMS noted the time-threshold approach was a primary barrier to CoCM program adoption.

Practices with CoCM programs established before January 1, 2026, must update their charge master, EHR charge capture, and monthly claim submission workflow to use G0568, G0569, and G0570. Practices that continue submitting 99492, 99493, or 99494 for dates of service after December 31, 2025, will receive automatic denials. These denials can't be appealed on the basis of transition confusion. CMS published the change in the October 31, 2025 Final Rule with a 60-day implementation window. The new G-codes cross-walk to the legacy CPT codes in most clearinghouse systems, but billing teams must verify the cross-walk is active before January 2026 claims are submitted.

Why Claims Submitted With 99492, 99493, and 99494 After December 31, 2025 Are Automatically Denied

Claims submitted with CPT codes 99492, 99493, or 99494 for dates of service on or after January 1, 2026, are automatically denied by Medicare because these codes were replaced by G0568, G0569, and G0570 effective January 1, 2026, under the CY 2026 Medicare Physician Fee Schedule Final Rule. The legacy codes are no longer valid for Medicare billing. Commercial payers that have historically covered 99492 through 99494 must be contacted individually to confirm their equivalent G-code adoption timeline, as commercial plans may maintain coverage of the legacy codes on a different transition schedule.

G0560: Safety Planning Intervention for Patients at Elevated Suicide Risk

G0560 covers the Safety Planning Intervention, building a personalized, written list of coping strategies, social supports, professional contacts, and environmental safety steps for patients at elevated risk of suicide or risky substance use. CMS classifies SPI as an intervention rather than a risk assessment, and this distinction matters because it's separately billable from 90791 or 90792 risk screening components. G0560 requires the billing practitioner to order or supervise the intervention. See CMS Medicare Mental Health Coverage booklet, March 2026 for the G0560 requirement detail.

The clinical record must include: the patient's identified warning signs, internal coping strategies, social contacts and settings that provide distraction, people the patient can ask for help, and professional and crisis contacts including local emergency services. CMS specifies that the written plan must be given to the patient. Document the date SPI was delivered, the patient's response to the planning process, and whether the patient retained a copy. Practices serving high-risk populations in outpatient mental health, IOP, or post-discharge settings should build G0560 into their clinical workflow immediately.

G0544: Follow-Up Contacts Intervention for Post-Crisis Medicare Patients

G0544 covers Follow-Up Contacts Intervention, a series of proactive phone calls to patients at suicide risk or following an overdose, made after a crisis encounter or discharge from a higher level of care. CMS allows a maximum of four calls per calendar month. Each call requires documented patient consent because Part B cost-sharing applies to the service. This isn't a free patient touchpoint. The service may be billed incident-to the billing practitioner.

Patient consent must be obtained and documented before or during the first follow-up call. The consent must note that the patient understands Part B cost-sharing (copayment or coinsurance) applies. CMS makes consent a billing requirement, and claims submitted without documented consent are subject to recoupment. RCM teams managing FCI billing should build consent capture into the discharge workflow and create a monthly tracking log confirming four-call-per-month limits aren't exceeded. The billing code is G0544 and it bills once per month regardless of how many calls were completed up to the four-call limit.

G0552, G0553, and G0554: Digital Mental Health Treatment Device Codes

G0552 covers the supply and onboarding of a Digital Mental Health Treatment device, a digital therapeutic provided to the patient alongside ongoing behavioral health services. G0553 and G0554 cover the monthly treatment management associated with the DMHT device. These codes require that the device be FDA-cleared under 510(k) or De Novo authorization, that the billing practitioner prescribe or order the device, and that the practitioner incur the cost of supplying the device to the patient.

DMHT devices are provided incident-to ongoing professional behavioral health services and must be used in conjunction with an active behavioral health treatment plan of care. A provider can't bill G0552 for a digital app subscription without a current behavioral health treatment plan. The ordering practitioner must document that the FDA-cleared device is being used as part of a structured treatment program. CMS is continuing to gather information on DMHT pricing and may establish national payment rates in future rulemaking.

CPT 90849 Added to the Medicare Permanent Telehealth List for CY 2026

CMS added CPT 90849 (multiple-family group psychotherapy) to the Medicare permanent telehealth services list for CY 2026. CMS also removed the provisional versus permanent distinction for telehealth services, meaning all additions to the Medicare telehealth list are now considered permanent. This means partial hospitalization programs and IOP programs that use multi-family group formats can now bill 90849 for telehealth sessions without concern about provisional status expiration. Use modifier 95 for video sessions and POS 10 when patients are at home. IOP programs billing 90849 via telehealth should verify prior authorization for IOP programs billing 90849 requirements per payer before the first telehealth session.

The Dual Conversion Factor System: The Most Important Rate Change in Medicare History

Beginning CY 2026, Medicare uses two separate conversion factors for the first time in the program's history. Qualifying Alternative Payment Model participants receive a conversion factor of $33.57, a $1.22 increase from the 2025 rate. Non-qualifying APM practitioners receive a conversion factor of $33.40, a $1.05 increase. The 99484 cpt code description and all mental health billing codes are affected by this conversion factor split, with the applicable rate depending on the practice's APM participation status.

Most solo practitioners, small group practices, and independent behavioral health programs are not Qualifying APM participants and will receive the $33.40 conversion factor. Large health systems with behavioral health integration programs participating in Advanced APM models may qualify for the $33.57 rate. The difference is $0.17 per RVU, small per claim but significant at scale. A psychiatrist billing 500 RVUs per month sees a difference of $85 per month or $1,020 annually between the two conversion factor tracks.

Implementing the new 2026 CoCM codes (G0568, G0569, G0570) requires credentialing the billing practitioner, behavioral health care manager, and psychiatric consultant with every payer before the first monthly claim. MedSole RCM manages multi-provider behavioral health credentialing for CoCM programs at $99 per payer enrollment, the most affordable credentialing rate for integrated care programs in the market.

Telehealth Mental Health CPT Billing in 2026: Modifiers, POS Codes, and the $42 Per-Session Rule

Medicare's telehealth flexibilities for behavioral health are permanently codified as of 2026: geographic restrictions are permanently removed, the patient's home is a valid originating site, and audio-only mental health services remain permanently covered, creating a billing environment where the difference between POS code 02 and POS code 10 on a single claim determines whether a practice receives the facility rate or the higher non-facility rate. This is the behavioral health billing decision with the largest revenue per-claim impact in 2026.

Is Telehealth for Mental Health Permanent in 2026?

Yes. Medicare's telehealth flexibilities for behavioral health are now permanently codified, not temporary extensions. CMS permanently removed geographic and originating site restrictions for behavioral health telehealth services. Patients can receive mental health telehealth in their homes regardless of their geographic location. Audio-only telehealth for mental health is permanently covered. CMS's Telehealth FAQ, updated February 26, 2026, confirms these provisions are permanent and not subject to expiration. The only remaining timeline-based element is the in-person visit requirement for mental health telehealth, which doesn't take effect until after December 31, 2027. See CMS CY 2026 telehealth permanent services list for the full permanent list.

The Complete 2026 Telehealth Modifier Reference for Mental Health Codes

Payer requirements for telehealth modifiers aren't standardized. BCBS national plans accept modifier 95, but certain regional BCBS plans require GT. UHC accepts modifier 95 as standard. Magellan and Beacon each publish telehealth modifier requirements in their provider manuals. Practices billing multiple payers must maintain a payer-specific modifier matrix and update it whenever payer telehealth policies change. Verify telehealth coverage and accepted modifiers per payer before the first session.

POS 10 vs POS 02: The Place-of-Service Code That Determines Your Reimbursement Rate

POS 10 indicates the patient is receiving telehealth in their private home. POS 02 indicates the patient is receiving telehealth from any location other than their home. Medicare pays the non-facility rate when POS 10 is used and the lower facility rate when POS 02 is used. This has been policy since January 1, 2024, when CMS finalized the home telehealth payment at the non-facility rate. The behavioral health cpt codes processed under POS 10 generate meaningfully more revenue than the same codes processed under POS 02.

The revenue impact is specific. For CPT 90837 in 2026, the non-facility Medicare rate is approximately $154 to $158 while the facility rate is approximately $112 to $118. The difference is approximately $40 to $42 per session. A practice running 20 telehealth sessions per week where all patients are at home generates $840 per week more using POS 10 than POS 02. Over 50 billing weeks, that is $42,000 in annual revenue from a single POS code selection. Documenting the patient's location at the start of every telehealth session is a revenue decision, not a compliance formality.

POS Code Revenue Impact by CPT Code:

Audio-Only Telehealth for Mental Health: Modifier 93 and Modifier FQ Explained

Audio-only sessions occur when the patient doesn't have access to video technology, declines video, or has documented technical barriers to video connection. Medicare permanently covers audio-only telehealth for mental health services. Use modifier 93 for ongoing audio-only therapy sessions under the CMS 2026 standard. Use modifier FQ specifically for Medicare claims where the provider could have used video but the patient was unable or unwilling to use it.

The progress note must document: the patient's location at the time of the call, the reason video was not used (patient technology barrier, patient preference, or documented consent to audio-only format), the patient's verbal consent to audio-only treatment, the session start and stop times, and all other standard psychotherapy documentation elements. Missing documentation of why video was not used is the top denial cause for audio-only mental health telehealth claims, not the service itself.

The In-Person Mental Health Telehealth Requirement: What the 2027 Deadline Means

The statutory requirement that Medicare beneficiaries complete an in-person mental health visit within six months before their first mental health telehealth service is effective after December 31, 2027, not currently. CMS confirmed in the CMS Telehealth FAQ, updated February 26, 2026 that through December 31, 2027, this requirement is not active. Beneficiaries can begin mental health telehealth services without a prior in-person visit through the end of 2027.

Beginning after December 31, 2027, new mental health telehealth patients who haven't had an in-person visit with the provider within the prior six months will need to complete an in-person evaluation before telehealth therapy can begin. Beneficiaries who begin receiving services on or before December 31, 2027, aren't subject to this requirement retroactively. The in-person requirement applies only to new telehealth episodes initiated after that date.

New 2026 Direct Supervision Rule for Telehealth Group Practices

Starting January 1, 2026, CMS permanently redefined direct supervision to allow the supervising practitioner to fulfill the immediate availability requirement through real-time audio-video interactive telecommunications, excluding audio-only. This means a supervising psychiatrist or senior therapist can provide direct supervision of an intern or unlicensed staff member via video call in real time, satisfying the direct supervision standard without being physically on-site. Audio-only contact doesn't satisfy the 2026 direct supervision definition. The supervising practitioner must be visible and reachable via video.

Telehealth POS coding errors and missing modifier 95 are two of the most common sources of preventable revenue loss in mental health practices. MedSole RCM applies payer-specific telehealth modifier rules and POS codes to every behavioral health claim before submission. Connect with MedSole's behavioral health billing team to prevent telehealth claim errors.

Who Can Bill Mental Health CPT Codes in 2026: The Complete Provider Type Matrix

Provider type determines two critical variables in mental health billing: which CPT codes a provider can legally submit and what percentage of the Medicare Physician Fee Schedule they receive, with psychiatrists billing at 100 percent, PMHNPs at 85 percent, LCSWs at 75 percent, and LMFTs and LMHCs at 75 percent under the fully implemented 2024 Medicare expansion. These mental health billing codes rules are not interchangeable across credential types, and the rate differential is significant at scale.

Why Provider Type Determines Both Eligibility and Reimbursement Rate

Provider type impacts billing in two ways. First, scope of practice determines which codes a provider can bill. LMFTs can bill 90834 but not 90792, because 90792 requires prescriptive authority. Second, Medicare credential tier determines the payment percentage. The same 90837 service generates $154 to $158 for a psychiatrist, $131 to $134 for a PMHNP, and $115 to $118 for an LMFT or LCSW. The code is identical; the payment differs because the credential differs.

Commercial payers don't uniformly follow Medicare's credential-tier structure. BCBS and UHC typically apply the same contracted rate to all licensed mental health providers for the same CPT code regardless of credential tier, meaning the psychologist and the LCSW receive identical BCBS rates for 90837 in many markets. However, Magellan, Beacon, and Optum behavioral health carve-out plans frequently tier rates by credential, paying psychologists and psychiatrists higher rates for the same code than LCSWs or LPCs.

LMFT and LMHC Medicare Billing in 2026: Fully Implemented, 75 Percent of PFS

Licensed Marriage and Family Therapists and Licensed Mental Health Counselors became eligible Medicare Part B providers on January 1, 2024. By 2026, this expansion is fully implemented and LMFTs and LMHCs bill Medicare independently under their own NPI at 75 percent of the Medicare Physician Fee Schedule. For CPT 90837, the LMFT rate in 2026 is approximately $115 to $118. For CPT 90834, the rate is approximately $98. For CPT 90791, the rate is approximately $130 to $133. See APA Services 2026 LMFT and LMHC Medicare billing guidance for the official expansion details.

PECOS enrollment is mandatory before any LMFT or LMHC can submit a Medicare mental health claim. The enrollment process requires a completed CMS-855I form or online CMS PECOS provider enrollment application, takes 60 to 120 days, and requires the provider to be licensed in the state where services are delivered. They can't bill codes that require medical services: 90792 and all E/M codes (99213 through 99215) are outside their scope.

PECOS enrollment gives LMFTs and LMHCs Medicare billing rights only. Commercial payer enrollment (BCBS, UHC, Aetna, Cigna) requires separate panel applications with each carrier. Behavioral health carve-out networks, Magellan, Beacon, and Optum, require additional separate applications that are entirely independent from the commercial medical network enrollment. An LMFT who is in-network with BCBS medical may still be out-of-network with the BCBS-contracted behavioral health carve-out. This distinction is the source of the most expensive and most preventable denial pattern in mental health billing.

PMHNP Billing: The 85 Percent Rule, 90792 Eligibility, and Incident-To Requirements

Psychiatric Mental Health Nurse Practitioners with prescriptive authority and active PECOS enrollment bill Medicare at 85 percent of the physician fee schedule under their own NPI. For CPT 90792, the PMHNP rate is approximately $168 to $174 in 2026 (85 percent of $198 to $205). For CPT 99214, the rate is approximately $115 (85 percent of $135.61). This is the psychiatric medication management cpt code billing scenario that most PMHNP practices handle daily, and the 85 percent rule is the foundational rate to understand.

When a PMHNP bills incident-to a supervising physician, the claim submits under the physician's NPI and receives 100 percent of the physician fee schedule rate rather than 85 percent. The conditions for incident-to are strict: the supervising physician must have personally evaluated the patient and established the treatment plan on the patient's first visit, the physician must be immediately available (which in 2026 includes availability via real-time audio-video under the new direct supervision rule), and the PMHNP can't address any new clinical problem during the incident-to visit. If the patient presents with a new complaint, the PMHNP must either bill under their own NPI or have the physician evaluate the new problem.

The 2026 Provider Reimbursement Rate Matrix

These rates apply to claims submitted under each provider's own NPI. Commercial payers don't follow this exact credential-tier structure and may pay identical rates to all licensed mental health providers for the same CPT code. Practices should verify their specific contracted rates per payer and per provider type to identify underpayment patterns. For the complete 90837 rate breakdown by provider type including commercial payer benchmarks, see our CPT 90837 reimbursement rates by provider type guide.

Behavioral Health Carve-Out Credentialing: The Denial Cause No Competitor Discusses

Many commercial insurers administer their mental health and substance use disorder benefits through a separate behavioral health organization, called a behavioral health carve-out. The most common carve-out administrators are Magellan Health, Beacon Health Options (owned by Carelon Behavioral Health), and Optum Behavioral Health (owned by UnitedHealth Group). A provider credentialed with BCBS of Illinois for medical services is not automatically credentialed with Magellan, which administers BCBS of Illinois behavioral health claims under a separate contract.

When a mental health provider submits a 90837 or 90791 claim to BCBS but isn't credentialed with the BCBS-contracted behavioral health carve-out (Magellan, in this example), the claim denies as "provider not enrolled" or "provider not in network for this benefit." The patient's BCBS card doesn't distinguish between medical and behavioral health benefits. The provider has no indication at enrollment that two separate credentialing processes are required. This is the most common hidden denial cause in outpatient mental health billing and the one most likely to generate large-volume retro-denials when discovered on audit.

Before seeing the first mental health patient under a commercial plan, billing teams must identify whether that plan uses a behavioral health carve-out and, if so, must credential with both the commercial medical network and the carve-out administrator. The credentialing applications for Magellan, Beacon, and Optum are separate from BCBS, UHC, and Aetna applications and require separate NPI validation, license verification, and panel approval. MedSole RCM's behavioral health credentialing team identifies carve-out requirements per payer per state and manages both applications simultaneously at $99 per payer enrollment. LMFTs and LMHCs navigating PECOS enrollment alongside commercial carve-out credentialing can complete both tracks simultaneously with our credentialing solutions for therapists and counselors.

LMFTs completing PECOS enrollment and behavioral health practices adding new providers to commercial carve-out networks need credentialing managed by a team that knows the difference between medical network enrollment and carve-out credentialing. MedSole RCM handles both at $99 per payer. Start credentialing with MedSole RCM behavioral health credentialing today.

NCCI Same-Day Bundling Rules for Mental Health CPT Codes: The Four Denial Triggers

The Medicare National Correct Coding Initiative Policy Manual, Chapter XI, effective January 1, 2026, establishes four same-day bundling rules for mental health CPT codes that generate automatic claim denials when violated. These are rules separate from general medical coding bundling logic and they apply specifically to psychiatric and psychological services. The mental health billing codes governed by NCCI Chapter XI include every psychotherapy, evaluation, and family therapy code in this guide. See Medicare NCCI Policy Manual Chapter XI, effective January 1, 2026 for the primary authority.

NCCI Rule 1: Do Not Bill 90791 or 90792 With Psychotherapy on the Same Date

Because psychotherapy (codes 90832 through 90838, 90839, 90840, 90846, 90847, 90849, and 90853) includes continuing psychiatric evaluation as an inherent component of the service, CPT 90791 and CPT 90792 are not separately reportable with any individual, group, family, crisis, or other psychotherapy code for the same date of service. If a therapist conducts both a diagnostic evaluation and a psychotherapy session on the same day, only one can be billed.

This rule applies most commonly at initial intake. A therapist who conducts a 90-minute first session that includes both a comprehensive intake assessment and a brief therapeutic intervention can't bill 90791 plus 90834 on the same date. The correct approach is to determine which component was predominant and bill accordingly. Most practices bill 90791 for the intake session and begin psychotherapy billing with the second session. Document the intake note as a purely diagnostic evaluation to support 90791 and avoid any documentation that describes therapeutic interventions on the same date.

NCCI Rule 2: 90832 Through 90838 Already Include Family Members as Informants

NCCI specifies that CPT codes 90832 through 90838 include all psychotherapy provided to a patient with family members as informants, if present, during a single date of service. This means that if a therapist conducts individual therapy for 45 minutes and the patient's spouse is present for 10 minutes providing collateral information, that session is still billed as 90834, not 90834 plus 90847. The cpt codes for psychotherapy in the individual therapy range already include this informant scenario without a separate family therapy code.

Reflexively billing 90847 every time a family member participates in any portion of an individual session is an NCCI violation. For 90847 to be separately billable alongside individual therapy, the family therapy component must constitute a separately identifiable service with a distinct therapeutic focus, conducted during a separate time interval from the individual therapy, and documented independently with its own clinical note or note section showing separate time allocation.

NCCI Rule 3: Family Therapy and Individual Therapy on the Same Date Require Separate Time Intervals

NCCI specifies that 90846 and 90847 may be reported separately from individual psychotherapy codes (90832 through 90838) on the same date of service only when the family therapy is performed as a separate and distinct service during a separate time interval from the individual therapy. Separate time intervals means the therapist concludes the individual session, has a clear break, and then conducts the family session as a distinct encounter, not a continuous session where family members join partway through.

For same-date individual therapy and family therapy billing, the clinical record must show: individual therapy time (for example, 2:00 PM to 2:46 PM, CPT 90834), a noted transition between services, and family therapy time (for example, 3:00 PM to 3:35 PM, CPT 90847). The two notes must have different therapeutic content, different goals addressed, and different clinical documentation. Our CPT 90834 same-day billing documentation guide includes documentation templates for same-date individual and family therapy sessions.

NCCI Rule 4: E/M Codes Cannot Be Billed With 90791 or 90792

NCCI specifies that E/M codes shall not be reported with 90791 or 90792 on the same date of service. This applies to all E/M codes including 99213, 99214, and 99215. The psychiatric diagnostic evaluation codes (90791 and 90792) are considered comprehensive evaluations that encompass all history, examination, and medical decision-making components that would otherwise justify a separate E/M code. Psychiatrists and PMHNPs who conduct an evaluation on the same day as medication management must choose between billing 90792 alone or the E/M code alone, not both.

NCCI bundling errors on mental health claims are preventable with a pre-submission scrub that checks same-day code pairs against current NCCI edits. MedSole RCM applies NCCI validation before every behavioral health claim leaves the clearinghouse, catching bundling errors that would otherwise generate denials, appeals, and delayed revenue. See how MedSole prevents NCCI denials for mental health practices.

IOP and PHP Billing Codes, MHPAEA Parity Rights, and Denial Prevention in 2026

Intensive outpatient and partial hospitalization programs operate under a separate billing framework from standard outpatient mental health: using UB-04 claim forms, revenue codes, condition codes, and a combination of per-diem and per-component billing that differs by payer type, while the MHPAEA 2025 Final Rule, effective January 1, 2026, gives behavioral health practices new legal tools to challenge discriminatory prior authorization and session limit policies. The mental health billing infrastructure for IOP and PHP is significantly more complex than standard outpatient billing, and the risks of manual billing in behavioral health at this level of care are substantial.

Intensive Outpatient Program (IOP) CPT Codes and Billing Requirements

Intensive outpatient programs require a minimum of nine hours of structured programming per week, typically delivered in three three-hour sessions. For Medicare billing, IOP services are billed per component: each psychotherapy group session (90853), individual therapy session (90834 or 90837), and medication management service (99214) is billed separately on the UB-04 claim form. For commercial payers, IOP is typically billed on a per-diem basis using HCPCS code S9480. The iop cpt codes structure is fundamentally different from standard outpatient billing, and billing teams new to IOP programs need separate training on both Medicare and commercial billing workflows.

IOP claims submit on UB-04 claim forms rather than CMS-1500 forms. Revenue code 0904 identifies the partial hospitalization or IOP service. Condition Code 92 identifies the IOP episode on the UB-04. Commercial plans billing S9480 per diem don't require itemized component billing, as the per-diem rate covers all services delivered that day. Practices moving from outpatient to IOP billing face a significant form and code structure change that requires EHR and billing software reconfiguration.

Almost every commercial payer requires prior authorization for IOP admission and continued stay. BCBS, UHC, Aetna, and Cigna all require a pre-certification request that includes: the patient's primary diagnosis (F-code), the clinical indicators supporting the level of care, the proposed treatment plan, the expected episode length, and in most cases a physician or psychiatrist attestation of medical necessity. Admitting a patient to IOP without confirmed prior authorization is the most expensive billing error IOP programs make: the entire episode can be denied without appeal rights when authorization is absent. Practices that need prior authorization managed before every IOP admission use MedSole's prior authorization for IOP admission service.

Partial Hospitalization Program (PHP) Billing Codes and Revenue Code Rules

Partial hospitalization programs require a minimum of 20 hours of structured programming per week. PHP is a higher level of care than IOP and requires a physician certification that the patient would otherwise require inpatient psychiatric hospitalization. Medicare requires three specific revenue codes on PHP claims: 0905 (PHP general), 0912 (half-day PHP, under six hours), and 0913 (full-day PHP, six or more hours). Condition Code 41 on the UB-04 identifies the PHP episode. See CMS Outpatient Mental Health IOP billing guidance for the PHP billing rules.

Medicare pays PHP services under the Outpatient Prospective Payment System using HCPCS code H0035 or the program-specific code series. Commercial payers typically reimburse PHP on a per-diem basis. BCBS per-diem rates for PHP range from $380 to $680 per day depending on geography and contract tier. UHC per-diem rates range from $350 to $620. Practices billing PHP must verify per-diem rates in their specific commercial contracts rather than using national averages, as PHP rates vary more widely than any other mental health billing category.

The MHPAEA 2025 Final Rule and What It Means for Mental Health Billing in 2026

The Mental Health Parity and Addiction Equity Act 2025 Final Rule became effective January 1, 2026. Published by the Departments of Labor, Health and Human Services, and Treasury, this rule establishes the most stringent mental health parity enforcement standards in the law's history and directly affects prior authorization requirements, non-quantitative treatment limitations, and the comparative analysis obligations that insurers must perform for mental health benefits. See the MHPAEA 2025 Final Rule, Department of Labor for the complete regulatory text.

Under the MHPAEA 2025 Final Rule, insurers can't impose prior authorization requirements, session limits, or coverage restrictions on mental health and substance use disorder services that are more restrictive than the requirements applied to comparable medical and surgical benefits. If a payer requires prior authorization for the sixth outpatient mental health visit but doesn't require prior authorization for the sixth primary care visit, that's a parity violation. Billing teams can now formally challenge these policies using the comparative analysis documentation that insurers are required to provide upon request under the Final Rule.

When a payer denies mental health claims due to prior authorization requirements that don't apply to comparable medical services, the practice has the right to request the payer's comparative analysis under MHPAEA. If the payer's comparative analysis reveals that mental health benefits are more restricted than medical benefits, the denial can be appealed on parity grounds, not just clinical necessity grounds. This is a new appeal pathway that gives behavioral health billing teams legal standing to recover denials that would previously have been written off.

How to Use MHPAEA to Appeal Mental Health Claim Denials

The steps for appealing a mental health claim denial on MHPAEA parity grounds in 2026:

1. Identify the restriction: document the specific payer requirement (prior authorization, session limit, or non-quantitative treatment limitation) that is being applied to the mental health claim.
2. Request the comparative analysis: send a written request to the payer for their MHPAEA comparative analysis showing how the mental health restriction compares to the same restriction applied to medical or surgical benefits.
3. Review the analysis: compare the mental health restriction to the medical benefit standard. If the restriction is more stringent for mental health, document the disparity specifically.
4. File the parity appeal: submit the claim denial appeal with the parity violation documentation, citing the MHPAEA 2025 Final Rule and the specific provision that the payer's restriction violates.
5. Escalate if needed: if the payer doesn't resolve the parity violation at the internal appeal level, file a complaint with the state insurance commissioner, the Department of Labor (for ERISA plans), or HHS (for ACA marketplace plans).

Most parity violations in behavioral health billing involve prior authorization requirements for outpatient mental health that exceed those for comparable primary care services, and session limits on psychotherapy that don't apply to comparable medical visits. These are the two highest-frequency MHPAEA violation patterns that billing teams should flag systematically.

IOP and PHP programs need prior authorization management before admission and AR follow-up on denied episodes. MedSole RCM handles behavioral health authorization and AR follow-up for IOP and PHP programs at $99 per payer credentialing and 2.99 percent billing.

Top 10 Mental Health CPT Billing Errors in 2026 and How to Fix Them

Mental health cpt codes claims deny at 15 to 20 percent, more than double the denial rate for general medical claims, and most of those denials are preventable, caused by the same recurring errors in time-code selection, modifier application, ICD-10 primary code selection, telehealth POS coding, and credentialing gaps that billing teams can systematically eliminate. The risks of manual billing in behavioral health include every error on this list, and each has a quantifiable financial consequence.

Error 1: Billing 90837 for Sessions Documented at 50 Minutes. Billing CPT 90837 for therapy sessions where the progress note documents 50 minutes of face-to-face time. The threshold for 90837 is 53 minutes. A 50-minute session is CPT 90834. RAC auditors identify this pattern through automated note review, and every 90837 claim where the note documents under 53 minutes is subject to recoupment at the difference between 90837 and 90834 ($22 to $27 per session) across a six-year lookback period. Prevention: document exact start and stop times in every progress note. Build EHR alerts that flag 90837 claims when documented session time is under 53 minutes. Our CPT 90834 billing documentation guide includes the progress note language that supports time-based code selection.

Error 2: Wrong Telehealth POS Code Costing $42 Per Session. Using POS 02 on claims where the patient is receiving telehealth services at home, rather than POS 10. For CPT 90837, the per-session difference between POS 10 and POS 02 is $40 to $42 at 2026 Medicare rates. At 20 sessions per week, this error costs approximately $42,000 annually. Prevention: document the patient's location at the start of every telehealth session. Set POS code selection as a mandatory field in the billing workflow, defaulting to POS 10 when patients are at home.

Error 3: Billing Legacy CoCM Codes 99492 Through 99494 After December 31, 2025. Submitting claims with CPT 99492, 99493, or 99494 for dates of service on or after January 1, 2026. Every such claim auto-denies. CoCM programs billing monthly see this as a complete revenue gap for the entire month until claims are corrected and resubmitted. Prevention: update the charge master and EHR charge capture to use G0568, G0569, and G0570. Verify that your clearinghouse cross-walk is active for the new G-codes before January 2026 claims are submitted.

Error 4: Using Z63.0 as Primary ICD-10 for Family Therapy Claims. Billing CPT 90847 or 90846 with ICD-10-CM Z63.0 as the primary diagnosis. Z63.0 is a Z-code, not a mental health diagnosis. The denial rate for this error at practices using generic billing templates can exceed 30 percent of family therapy claims. Prevention: use the patient's documented F-code (F33.1, F41.1, F43.10) as the primary diagnosis on all family therapy claims. Use Z63.0 as a secondary code only.

Error 5: Missing Modifier 95 on Telehealth Claims. Submitting telehealth psychotherapy claims without modifier 95. The claim processes as an in-person service with a telehealth place of service code, a mismatch that triggers auto-denial. This generates 100 percent denial until corrected, and bulk telehealth claims with this error can approach timely filing limits before correction. Prevention: include modifier 95 as a required field in the telehealth billing workflow. Create a pre-submission claim scrub rule that flags any telehealth POS code (02 or 10) without modifier 95 on the CPT line.

Error 6: Billing 90833 Without a Primary E/M Code. Submitting CPT 90833 as a standalone claim without a paired primary E/M code (99213, 99214, or 99215). As a designated add-on code, 90833 can't be billed without its primary service, generating 100 percent auto-denial on every 90833 standalone claim. Prevention: configure billing software to require a primary E/M code before 90833 can be added to a claim. Verify that only prescribing providers (psychiatrists, PMHNPs) are submitting claims that include 90833.

Error 7: Credentialing With the Medical Network but Not the Behavioral Health Carve-Out. Treating BCBS, UHC, or Aetna credentialing as complete when the commercial medical network enrollment is approved, without separately applying to the behavioral health carve-out administrator (Magellan, Beacon, Optum). Every mental health claim submitted under the commercial plan denies as "provider not in network" until the carve-out credentialing is approved. Retro-credentialing isn't available at most carve-out administrators, meaning denied claims from the period before approval aren't recoverable. Prevention: before seeing the first mental health patient under any commercial plan, identify whether the plan uses a behavioral health carve-out and apply to both the commercial medical network and the carve-out administrator simultaneously.

Error 8: Per-Group Rather Than Per-Patient Billing for 90853. Submitting a single CPT 90853 claim for an entire group therapy session rather than one claim per group participant. A practice running 10-patient groups and billing one claim per session recovers $30 to $50 per session. The correct per-patient billing generates $300 to $500 per session, a 90 percent revenue shortfall per group. Prevention: configure the billing workflow so that 90853 requires a participant count and generates one claim per participant.

Error 9: Insufficient Documentation for 90785 Interactive Complexity Add-On. Submitting CPT 90785 on claims where the progress note doesn't identify which of the four qualifying criteria applied, or states only that "the session was complex." Post-payment audit denial of the add-on plus repayment demand for all 90785 claims in the lookback period where documentation doesn't meet criteria. Prevention: create a documentation template for 90785 that requires the note to name the specific criterion, describe how it affected the session, and document the clinical response.

Error 10: Timely Filing Violations on Behavioral Health Claims. Submitting behavioral health claims after the payer's timely filing deadline: 12 months from the date of service for Medicare, 90 to 180 days for most commercial plans. Claims submitted after the deadline are denied with no appeal rights: 100 percent unrecoverable loss per claim. Timely filing violations disproportionately affect mental health practices because behavioral health claims are denied more frequently, requiring resubmission cycles that can push corrected claims past the filing window. Prevention: submit all claims within 48 hours of the date of service. Maintain a weekly aging report flagging any unsubmitted or rejected claim approaching the timely filing deadline.

The risks of manual billing in behavioral health include every one of these ten errors, and the financial impact of each is quantifiable. MedSole RCM eliminates manual billing risk through automated pre-submission scrubbing, payer-specific edit rules, and dedicated AR follow-up for mental health claims at 2.99 percent of collections.

Mental Health CPT Codes FAQ: Answers to the Most Common Billing Questions

The fourteen most frequently asked questions about mental health CPT codes billing, answered with the operational detail and 2026 sourcing that current AI Overview responses haven't provided. See the AMA Behavioral Health Coding Guide for the official AMA authority on all mental health CPT codes.

What Are Mental Health CPT Codes?

Mental health CPT codes are five-digit billing identifiers maintained by the American Medical Association that healthcare providers use to describe and bill for psychiatric evaluations, individual psychotherapy sessions, group therapy, family therapy, and crisis interventions. The most commonly used mental health cpt codes in 2026 include 90791 for diagnostic evaluations ($174 to $178 Medicare), 90834 for 45-minute therapy sessions ($131 Medicare), 90837 for 60-minute sessions ($154 to $158 Medicare), and 90853 for group therapy ($30 to $50 per patient Medicare). These codes are required on all insurance claims submitted to Medicare, Medicaid, BCBS, UHC, Aetna, Cigna, and behavioral health carve-out plans.

What Is the Difference Between 90834 and 90837?

CPT 90834 covers individual psychotherapy sessions lasting 38 to 52 minutes at a 2026 Medicare rate of $131 nationally. CPT 90837 covers sessions lasting 53 minutes or more at a 2026 Medicare rate of $154 to $158. Both codes require documented start and stop times. Billing 90837 for a session documented at 50 minutes is upcoding under CMS guidelines. The audit risk for 90837 is higher than for 90834 because payers flag practices that consistently bill 90837 without session length documentation confirming the 53-minute threshold was met.

Can I Bill 90837 for a 50-Minute Session?

No. A 50-minute session falls within the 38 to 52 minute range and must be billed as CPT 90834. CPT 90837 requires documented face-to-face therapeutic time of 53 minutes or more. Billing 90837 for sessions documented at 50 minutes is upcoding under CMS guidelines and exposes the practice to RAC audit recoupment across a six-year lookback period at the difference between 90837 and 90834, which is approximately $22 to $27 per session at 2026 Medicare rates.

What Is the Difference Between 90791 and 90792?

CPT 90791 is a psychiatric diagnostic evaluation without medical services, no medication management, prescribing, or physical assessment, billed at a 2026 Medicare rate of $174 to $178. CPT 90792 includes medical services such as medication review and prescribing decisions and is billed at $198 to $205 Medicare in 2026. Only psychiatrists (MD/DO) and psychiatric nurse practitioners with prescriptive authority can bill 90792. LCSWs, LPCs, LMFTs, and LMHCs bill 90791 for diagnostic evaluations and can't bill 90792 under any circumstances.

Can a Mental Health Counselor Bill CPT 90791?

Yes. Licensed mental health counselors (LMHCs), licensed professional counselors (LPCs), and licensed clinical social workers (LCSWs) can bill CPT 90791 for psychiatric diagnostic evaluations without medical services. As of January 1, 2024, LMFTs and LMHCs became eligible Medicare Part B providers and bill 90791 at 75 percent of the Medicare Physician Fee Schedule, approximately $130 to $133 in 2026. PECOS enrollment is required before the first Medicare 90791 claim. LMHCs and LPCs can't bill CPT 90792, which requires prescriptive authority. See our CPT 90791 billing guide for PECOS enrollment steps and documentation requirements.

What CPT Code Do I Use for a 45-Minute Therapy Session?

Use CPT 90834 for a 45-minute individual therapy session. CPT 90834 covers sessions lasting 38 to 52 minutes of documented face-to-face psychotherapy. The 2026 Medicare rate for 90834 is $131 in non-facility settings nationally, with commercial payer rates (BCBS, UHC, Aetna, Cigna) typically ranging from $130 to $196 depending on geography and contract tier. Document the exact session start and stop times in the progress note to confirm the session falls within the 38 to 52 minute range that 90834 requires.

Can CPT Code 99214 and 90833 Be Billed Together?

Yes. CPT 99214 and 90833 can be billed together when a prescribing provider (psychiatrist or PMHNP) conducts both medication management and psychotherapy in the same visit, with both components separately documented. Append modifier 25 to 99214 to signal that it is a significant, separately identifiable E/M service performed on the same day as a psychotherapy service. The 2026 Medicare combined value is $217.11, which is $135.61 for 99214 plus $81.50 for 90833, compared to $154 to $158 for 90837 alone.

What Is CPT Code 90792 Used for?

CPT 90792 is used for a psychiatric diagnostic evaluation that includes medical services, specifically medication review, prescribing decisions, physical assessment elements, or laboratory order review. Only psychiatrists (MD/DO) and psychiatric nurse practitioners (PMHNPs) with prescriptive authority can bill 90792. The 2026 Medicare rate is $198 to $205 in non-facility settings. The documentation must include a specific medication review with drug names, dosages, and clinical reasoning. Notes that say "medications discussed" without specifics don't support 90792.

When to Use 90847 vs 90837?

Use CPT 90847 when the identified patient and family members participate together in a conjoint therapy session focused on the patient's diagnosed mental health condition. The family's participation is the therapeutic mechanism. Use CPT 90837 when only the identified patient is present for an individual therapy session of 53 minutes or more. The two codes can't be billed on the same date for the same patient unless the individual therapy and family therapy occur during clearly separate time intervals documented independently. The 2026 Medicare rate is $109 to $131 for 90847 and $154 to $158 for 90837.

What Are the New Mental Health CPT Codes for 2026?

The most significant new billing codes affecting mental health providers in 2026 include: G0568 (initial month Collaborative Care Model, replacing CPT 99492), G0569 (subsequent CoCM months, replacing 99493 and 99494), G0570 (General Behavioral Health Integration), G0560 (Safety Planning Intervention for patients at elevated suicide risk), G0544 (Follow-Up Contacts Intervention for post-crisis Medicare patients), and G0552, G0553, G0554 (Digital Mental Health Treatment device supply and management). CPT 90849 (multiple-family group psychotherapy) was also added to the Medicare permanent telehealth services list for CY 2026.

Can I Bill 90846 and 90847 on the Same Day?

Yes, with documentation requirements. CPT 90846 (family therapy without patient) and CPT 90847 (family therapy with patient) can be billed on the same date only if they were performed as separate and distinct services during separate time intervals. Both services must be independently documented with their own time allocations, therapeutic focus, and clinical note content. Frequent same-date billing of 90846 and 90847 without this documentation triggers audit review.

What Modifier Is Required for Telehealth Therapy in 2026?

Use modifier 95 for synchronous audio-video telehealth sessions with Medicare and most commercial payers in 2026. For audio-only sessions, use modifier 93 (CMS 2026 standard for ongoing audio mental health therapy) or modifier FQ (Medicare-specific audio-only). Always pair the modifier with POS 10 when the patient is at home, because POS 10 pays the higher non-facility rate. For state Medicaid programs in California, Illinois, and Missouri, append modifier HO to indicate master's degree level provider in addition to the telehealth modifier.

What Is the Difference Between 96130 and 96127?

CPT 96130 covers psychological testing evaluation: integrating test results, interpreting scores, making diagnostic decisions, writing reports, and providing feedback, at a 2026 Medicare rate of $121 to $124.74 per first hour. CPT 96127 covers brief emotional or behavioral screening, administering and scoring one standardized instrument such as the PHQ-9 or GAD-7, at $4.97 per instrument with a maximum of three instruments per visit. The two codes can't be billed on the same date of service for the same patient without modifier 59 and clinical documentation showing distinct necessity for both.

When to Use G0444 vs 96127?

Use G0444 specifically during a Medicare Annual Wellness Visit for the depression screening component. G0444 pays $18.25 and applies only to the AWV depression screening. Use CPT 96127 during any other type of office visit when administering brief emotional or behavioral screening instruments at $4.97 per instrument, up to three instruments per visit. Never bill G0444 and 96127 on the same date of service. They're mutually exclusive billing options for depression screening, with G0444 designated exclusively for the Medicare Annual Wellness Visit context.

Why Mental Health Practices Choose MedSole RCM for Behavioral Health Billing and Credentialing

Managing all of the coding decisions described in this guide simultaneously is the operational burden that outsourcing to a behavioral health-specific RCM company eliminates. Practices that bill 90847 and forget the Z63.0 ICD-10 trap, practices billing 90837 without time documentation, practices with Anthem BCBS credentialing but no Magellan enrollment, practices billing 90853 as a per-group code rather than per-patient: all of these patterns are preventable with the right billing infrastructure in place before the first claim submits.

MedSole RCM manages every mental health CPT code category in this guide: psychotherapy codes (90832 through 90837), evaluation codes (90791, 90792), add-on codes (90785, 90833, 90836, 90838), crisis codes (90839, 90840), group and family therapy codes (90846, 90847, 90853), testing codes (96127, 96130, 96136, 96138), HBAI codes (96156, 96158), and new 2026 G-codes (G0568, G0569, G0570).
