New Hampshire Medicaid Provider Enrollment: 2026 NHMMIS Portal, Application Types, and MCO Credentialing Guide

What changed for New Hampshire Medicaid provider enrollment in 2026

On April 23, 2026, CMS Administrator Mehmet Oz wrote to every governor and state Medicaid director, asking each state to submit a two-year provider revalidation strategy and to prioritize off-cycle revalidation of high-risk providers.

New Hampshire moved on it. NH Medicaid has started accelerated provider revalidations under that federal initiative, and many providers will be asked to revalidate ahead of their usual five-year cycle. Providers who don't respond faceclaims suspension and then termination of enrollment.

Two other 2026 changes land on New Hampshire providers. TheCY 2026 application fee is $750 for institutional providers, effective January 1 through December 31, 2026, and physicians and non-physician practitioners are exempt. CAA 2023 Section 5123 provider directory requirements took effect July 1, 2025, and NH Medicaid now collects extra directory data from enrolled providers.

Neither change touches the NHMMIS application itself. This guide covers New Hampshire Medicaid enrollment for new providers, credentialing with the three managed care plans, and the 2026 revalidation cycle.

Which NH Medicaid provider enrollment application do you need?

NH Medicaid offers four provider enrollment applications, plus a separate Trading Partner application for electronic data exchange. Your answer depends on whether you bill, who you bill under, and whether you render care.

There's no single Medicaid NH provider enrollment form to download. Each type opens as its own online application inside NHMMIS, and picking the wrong one costs you the whole submission.

Billing Group and Billing Individual applications

A corporation, partnership, or group entity files the Billing Group application under its FEIN. Sole proprietors billing under a Social Security Number file the Billing Individual application instead.

TheBilling Individual application already covers rendering, ordering, and prescribing. Don't stack a separate non-billing application on top of it.

Non-Billing Rendering and ORP applications

Every clinician rendering services under a billing group enrolls separately as a Non-Billing Rendering provider and stays affiliated with that group. Without the affiliation, claims for their services won't process.

That's the step practices skip. A physician who joins a group and bills under the group's FEIN still needs an individual non-billing rendering enrollment tied to the group provider ID. Miss it and you start over.

Trading Partner enrollment for EDI

Trading Partner enrollment sits outside the four provider applications. Any entity exchanging electronic data with NH Medicaid files it on its own track in NHMMIS.

One more rule shapes how you file: every physical service location gets its own NH Medicaid provider ID. A group can request several at once using the additional service location election, then add more later through the NHMMIS self-service portal.

Every state Medicaid program runs its own application set, and New Hampshire's doesn't match anyone else's. Our50-state Medicaid enrollment guide covers how the rules shift across state lines.

Selecting the wrong type means filing a new application rather than amending the old one. MedSole RCM confirms the application type before submission as part of itsNH Medicaid enrollment support, and handles Medicaid NH provider enrollment at $99 per payer per provider.

Do ordering, referring, and prescribing providers have to enroll in NH Medicaid?

Yes, for fee-for-service claims. Non-billing providers who order, refer, or prescribe supplies, services, or pharmaceuticals for NH Medicaid fee-for-service members must enroll with NH Medicaid.

Under42 CFR 455.410, an ORP provider required or listed on a fee-for-service claim must be enrolled in NH Medicaid, and their NPI has to appear on the claim. NH DHHS layers four rules on top of the federal requirement.

The rule reaches medical and dental providers who write prescriptions. A referring provider isn't required on the claim, though any referring provider you do list must be enrolled. Providers already enrolled as billing or rendering providers skip ORP enrollment.

The requirement also stops at fee-for-service. Claims sent to the three Medicaid Care Management health plans follow each plan's own contract terms, so the federal ORP rule doesn't reach them.

New Hampshire Medicaid provider enrollment for non-billing providers uses a shortened online application, and the same form covers both rendering and ORP.

An unenrolled ORP provider on your fee-for-service claim produces a denial that the billing provider absorbs. Verifying enrollment before you submit takes one call to NH Medicaid Provider Relations at (866) 291-1674.

How to enroll through the New Hampshire MMIS Health Enterprise Portal

NH Medicaid provider enrollment runs online through the New Hampshire MMIS Health Enterprise Portal at nhmmis.nh.gov, operated by Conduent as fiscal agent for NH DHHS. No downloadable application form exists.

Step 1: Open the correct application in NHMMIS

1. Go to the Provider tab on the main menu bar of theNH Medicaid provider portal, select Enrollment, then choose your application from the Become a Provider page. The portal loads different field sets for billing groups, billing individuals, non-billing providers, and Trading Partners, so the type you pick changes what it asks for.

Step 2: Complete ownership and managing employee disclosures

1. Enter the legal name as filed, the FEIN or SSN, every owner holding 5 percent or greater interest, all board members, and all managing or directing employees. Federal screening needs a Social Security Number for each disclosed individual, and NH Medicaid cancels applications that arrive without them.

Step 3: Upload required documents before submission

1. Upload every required document before you try to submit. The portal blocks submission until the uploads are done. You can fax supplementary documentation, but a fax never replaces the upload step.

Step 4: Submit and record your Application Tracking Number

1. Write down the Application Tracking Number the moment it appears. It's the only key to your application status, and the only way to recall a saved application later. Saved applications stay recallable for 12 months, using the Application Tracking Number together with the SSN or FEIN on the file.

Portal access runs through your Organization Administrator, who resets passwords and manages user accounts. Providers holding multiple Medicaid IDs register a separate User ID for each service location.

When nobody can get in, the Provider Relations Unit answers at (603) 223-4774 or (866) 291-1674. Providers without internet access can ask about alternate arrangements on the same lines.

Each state runs a different portal with different rules, and the NH MMIS field logic shares little with its neighbors. OurNew York Medicaid enrollment guide shows how far apart two state systems can sit.

What documents does New Hampshire Medicaid enrollment require? There's no application PDF

NH Medicaid has no downloadable provider enrollment form. Searches for a Medicaid NH provider enrollment form PDF come up empty because the application only exists online inside NHMMIS. Supporting PDFs do exist, and they cover what you upload with it.

Required for every enrollment type

Four documents follow every application whatever the type: the Provider Participation Agreement, the Enrollment and Revalidation Signature Page, a license or license verification, and NPI verification.

NH Medicaid publishes the master list asRequired Enrollment Documents to Upload with Application, in the Documents and Forms area of NHMMIS. Check it against your file before you submit, because documentation required for Medicaid in New Hampshire shifts by provider type.

Additional documents for billing groups

A billing group adds a signed W-9 and IRS Tax ID or FEIN verification. For a group, the Owner, General Partner, Board Officer, or a Managing or Directing Employee signs most documents. A practice manager's signature won't clear unless that person holds one of those roles.

Additional documents for billing individuals

A billing individual adds a signed W-9 and proof of Social Security Number, and signs the documents personally.

Additional documents for facilities

A facility or entity adds its facility license, CLIA certification where the services call for it, a W-9, and FEIN verification.

Separate PDFs handle what comes during and after the Medicaid provider enrollment application: the EFT Agreement, the ERA Enrollment Application, the Change of Information Form, and the Managing or Directing Employee Appointment or Removal Form.

The Signature Page carries an obligation that outlives the application. Report changes to NH Medicaid within 30 days of the effective date.

One correction worth stating plainly, because plenty of published guides get it wrong: CAQH ProView isn't part of the NHMMIS state application. Nothing in New Hampshire Medicaid enrollment at the state layer touches CAQH. It matters when you credential with the three managed care plans, and that's a separate process with separate paperwork.

NH Medicaid risk levels, site visits, and fingerprint background checks

NH Medicaid screens every enrollment application at one of three federal risk levels, and the level decides whether you get a site visit, fingerprinting, or neither.

Limited, moderate, and high risk screening

• Limited risk: license verification and federal database checks
• Moderate risk: everything in limited screening, plus an on-site visit
• High risk: everything in moderate screening, plus fingerprint-based criminal background checks for every person holding 5 percent or greater direct or indirect ownership

Thethree-tier framework sits in 42 CFR Part 455 Subpart E, and every state Medicaid agency works from it. New Hampshire adds a designation of its own on top.

Which NH provider types start at high risk

Under He-W 520.06, NH designates providers of home health services or durable medical equipment services as high risk. The same rule carves out an exception: providers going through revalidation under 42 CFR 455.414 don't land in high risk on that basis alone.

Read that twice if you run a home health agency or a DME company in New Hampshire. Filing a new application, adding a practice location, or re-enrolling puts you at high risk from day one, so budget for fingerprinting instead of reacting to a notice. Revalidation doesn't carry the same designation.

NH DHHS calls the check a Fingerprint-based Criminal Background Check, shortened to FCBC, and notifies the provider when one is required based on the risk level assigned to the provider type.

When a Medicare site visit counts

All moderate and high risk providers get a site visit. A Medicare site visit completed within the past five years satisfies the NH Medicaid site visit requirement at revalidation, which saves a scheduling cycle for practices already through PECOS. OurMedicare enrollment guide covers what that PECOS record needs to show.

When you're unsure whether a site visit applies to you, the DHHS Program Integrity Unit answers at (603) 271-8029.

How long does NH Medicaid provider enrollment take?

NH Medicaid publishes no standard processing timeline for provider enrollment applications.

What the state publishes

NH Medicaid states thatprocessing is unique to the provider type, the individuals associated with the application, and whether the application was complete and accurate at submission. No service level exists in any NH DHHS document.

Any vendor quoting a guaranteed New Hampshire Medicaid provider enrollment turnaround is quoting an internal average and calling it a state commitment. Ask which document it came from.

The one timeline New Hampshire does publish

NH DHHS sets credentialing deadlines for the managed care plans even though it sets none for its own fee-for-service applications. Each plan processes a clean and complete credentialing application within 30 calendar days for primary care providers and 45 calendar days for specialty care providers.

When a plan asks for new or missing information, it acts on what you send within 10 business days. The clock starts when the plan receives a clean and complete file, and stops on the date of your written notice of network status. Submit a file with gaps and the clock never starts at all.

What drives your timeline

How long it takes to get on Medicaid in NH as a provider comes down to five things.

• Application type. ORP and rendering applications carry less to screen than billing group applications.
• Risk level. Moderate risk adds a site visit. High risk adds an FCBC.
• Completeness. Missing ownership data or an unsigned document triggers a request for information, and your response speed sets the new pace.
• Ownership complexity. NH Medicaid screens every disclosed owner and board member on their own.
• Change of ownership. A change of ownership is a new application, never an amendment.

Clean applications with no risk elevation clear faster than files needing an FCBC or a site visit. That's an observation from our enrollment desk, and we won't dress it up as a day count New Hampshire has never published.

MedSole RCM audits every NH Medicaid application against the state's own document checklist before submission, because a request for information costs more time than the audit does.

How to check your NH Medicaid provider enrollment application status

Check NH Medicaid provider enrollment application status in the New Hampshire MMIS Health Enterprise Portal using your Application Tracking Number.

1. Go to the Provider tab on the main menu bar inNHMMIS and select Enrollment.
2. Find the Application Status box on the right-hand side of the page.
3. Enter the Application Tracking Number, marked with an asterisk.
4. Click Submit to see the current status.

The Application Tracking Number is the only way to check NH Medicaid application status; there is no lookup by name, NPI, or Tax ID.NH Medicaid states there's no other option to search application status. Lose the number and you're calling Provider Relations to get back in.

An NH Medicaid provider login isn't needed for a status check. The Application Status box sits on the public page, so front desk staff can check without portal credentials.

Saved but unsubmitted applications stay recallable for 12 months, using the Application Tracking Number together with the SSN or FEIN on file.

Provider Relations answers at (603) 223-4774 or (866) 291-1674, Monday through Friday, 8:00 AM to 5:00 PM EST.

Approval arrives as a Welcome Letter carrying your new NH Medicaid Provider ID. Each physical service location receives its own ID, so a three-site group gets three numbers.

How to verify a provider is enrolled in NH Medicaid before you bill

Call the NH Medicaid Provider Relations Call Center at 1-866-291-1674 or 603-223-4774, Monday through Friday, 8:00 AM to 5:00 PM, and the agent will confirm whether a provider is enrolled in NH Medicaid.

The reason this matters sits in your denial report. On fee-for-service claims, an ordering, referring, or prescribing provider who isn't enrolled in NH Medicaid takes your claim down with them. The billing provider absorbs that denial, not the ORP provider who caused it.

NH Medicaid tells billing providers to verify with the ordering provider directly. When direct confirmation isn't possible, the call center answers the question in a few minutes. Finding a Medicaid provider number for someone else's enrollment isn't a portal search in New Hampshire, so an NH Medicaid provider lookup means picking up the phone.

A second search intent hides behind the same words. Under CAA 2023 Division H, Title V, Section 5123, effective July 1, 2025, Medicaid fee-for-service programs publish accurate, updated, searchable provider directories and refresh them quarterly. NH Medicaid has been collecting extra directory data from enrolled providers to comply.

That's why the demographic fields on your NHMMIS record carry more weight than they used to. A stale phone number in the state directory sends referrals to somebody else.

An unenrolled ORP provider on an otherwise clean claim is an avoidable denial. Reworking one burns staff time on money that should have landed the first time, and the ORP check that prevents it takes two minutes. Working the ones that slip through anyway is whatdenial management services are for.

Credentialing with New Hampshire's three Medicaid managed care plans

Enrolling with NH Medicaid does not enroll you with any managed care plan. Providers serving members in New Hampshire's Medicaid Care Management program enroll with the state first, then contract and credential separately with each health plan.

Why state enrollment alone doesn't get you paid

Providers who see only fee-for-service members need state enrollment and nothing more. Anyone treating Medicaid Care Management members, which covers most of New Hampshire's Medicaid population, needs state enrollment plus a separate contract and credentialing file with each of thethree health plans.

The sequencing detail is worth getting right, because plenty of published guides state it backwards. NH Medicaid lets you begin MCO enrollment before your state application is approved. What you can't do is finish it, since the plans can't complete credentialing until NH Medicaid issues your provider ID.

Practices that sit on the MCO applications waiting for state approval give up that overlap and lose weeks they never had to lose.

How to get credentialed with Medicaid in New Hampshire has two answers because there are two layers, and they're built to run at the same time. OurMedicaid MCO credentialing guide covers how that parallel track works across states.

Two steps sit inside every MCO file. Contracting settles which services you provide and what the plan pays. Credentialing verifies your qualifications and licensure. Each plan runs credentialing through CAQH ProView, so keep the attestation current, because an expired one stalls the file with no notice.

One structural difference catches new enrollees off guard: NH Medicaid has no contracting step at all. Fee-for-service rates come from the public NH Medicaid Fee Schedule, so there's nothing to negotiate on the state side and everything to negotiate on the plan side.

AmeriHealth Caritas New Hampshire

AmeriHealth Caritas New Hampshire starts network requests with acontract inquiry form. Provider network answers at 1-888-599-1479 and credentialing has its own line at 1-866-610-2770. The plan re-credentials practitioners at least every 36 months, and requires an active NH Medicaid ID and NPI before participation.

NH Healthy Families

NH Healthy Families operates as Granite State Health Plan, a Centene subsidiary, and runs its ownprovider portal and credentialing workflow separate from the other two plans. The NH Healthy Families provider portal handles contracting requests, roster updates, and status checks.

WellSense Health Plan

WellSense Health Plan covers New Hampshire Medicaid alongside a wider New England footprint. Provider contracting and credentialing run through itsjoin the network process, which lists the current WellSense provider and credentialing contacts for New Hampshire.

Confirming which plan a member is enrolled in

NH DHHS instructs providers to check and confirm eligibility and health plan enrollment before providing services, and MMIS holds eligibility information for every NH Medicaid member.

Members under the Granite Advantage Health Care Program choose a plan or get auto-assigned, then can switch for any reason during their first 90 days and again at open enrollment. A member's plan changes without your front desk hearing a word about it.

Verifying "Medicaid" at check-in isn't enough. You need the plan, on the date of service, before the visit. That's whateligibility and benefit verification exists to catch.

MedSole RCM handles NH Medicaid provider enrollment at $99 per payer per provider and full-cycle medical billing at 2.99 percent of collections. Outsourced payer enrollment in the US market runs $150 to $300 per payer per provider, and full-service RCM runs 4 to 9 percent of collections.

We open the NHMMIS application and all threemanaged care credentialing files together, so the plan-side work is already moving by the time your provider ID lands.

EDI, EFT, and ERA setup before your first NH Medicaid claim

NH Medicaid approval doesn't switch on electronic claims, electronic payment, or electronic remittance. Each one takes its own setup, and each one fails in a way nobody notices for months.

Trading Partner enrollment for electronic claims

Trading Partner enrollment is the fifth NHMMIS application track, separate from provider enrollment, and it authorizes electronic data exchange with NH Medicaid.

New Hampshire publishes EDI companion guides for the transaction sets a practice touches: 837P for professional claims, 837I for institutional, 837D for dental, 835 for remittance advice, 270 and 271 for eligibility inquiry and response, 276 and 277 for claim status, and 278 for service authorization. Your clearinghouse will ask which guides exist before it maps a single field.

EFT enrollment

The NH Medicaid EFT Agreement takes a bank letter or a voided check. Report banking changes ahead of the change rather than after it.

The EFT agreement folds into the Provider Participation Agreement, which makes your EFT terms contractual instead of administrative. Practices tend to treat a bank change as a back-office update. NH Medicaid treats it as a contract amendment.

ERA enrollment and the CCD+ reassociation requirement

NH Medicaid's ERA Enrollment Application tells providers to work with their bank to obtain the CORE-required CCD+ reassociation data elements.

NH Medicaid's ERA enrollment requires CORE-mandated CCD+ reassociation data elements from the provider's bank so the EFT deposit and the 835 remittance can be matched. If your bank strips them out, deposits land and remittances land, and nothing ties together on its own. Somebody posts by hand, or worse, posts by assumption.

Picture where that ends. A practice sits enrolled, credentialed, and getting paid, while its ledger drifts away from what the contract says it should show. Nobody catches it at enrollment, because enrollment worked. It surfaces at quarter close, inside an aging report nobody can explain.

MedSole RCM configures EFT and ERA during enrollment and checks each remittance against the contracted rate the day it posts, soERA payment posting accuracy holds from the first deposit instead of getting reconstructed three months later.

What you agreed to in the NH Medicaid Provider Participation Agreement

The Provider Participation Agreement you sign at NH Medicaid enrollment carries obligations that run for the life of the enrollment, and NH Medicaid enforces them long after approval.

Record retention and exclusion screening

NH Medicaid providers accept Medicaid payment as payment in full and can't bill members for the balance. Selling Medicaid accounts receivable to a collections agency isn't permitted either.

Keep billing records supporting each claim for at least six years from the date of service, or until any personal action started inside that six-year window is resolved, whichever runs longer.

Screen employees and contractors against the OIG List of Excluded Individuals and Entities every month. The OIG updates that database monthly, and NH Medicaid expects monthly checks rather than quarterly ones. Report any exclusion you find to Medicaid Program Integrity.

Reporting changes within 30 days

Report changes to NH Medicaid within 30 days of the effective date, using the Change of Information Form. Managing and directing employee changes go on the separate Managing or Directing Employee Appointment or Removal Form, and route to Conduent for screening.

NH Medicaid won't accept a change by telephone, and won't recognize a change that shows up only on a claim form. Claims pay against what sits on the provider record, so an outdated record pays like an outdated record.

Directory data requirements under CAA 2023

Under CAA 2023 Division H, Title V, Section 5123, effective July 1, 2025, Medicaid fee-for-service programs publish accurate, updated, searchable provider directories and refresh them quarterly.

Thefederal minimum data set now covers whether you're accepting new Medicaid patients, whether you offer covered services by telehealth, your website, and what accommodations your office provides for patients with physical disabilities. NHMMIS Self-Service lets you update those details directly. The samefederal directory requirements apply in every state.

Enrollment is not transferable

NH Medicaid enrollment is not transferable and terminates upon sale or transfer of ownership. A current Medicaid ID can't move to a new owner. NH Medicaid terminates it and issues a new number to the new ownership.

Separately from enrollment, NH Medicaid runs a fee-for-service service authorization program submitted by secure email, and Magellan handles pharmacy prior authorizations. Each health plan then runs its ownprior authorization support process on top of both.

Change of ownership: the 35-day rule and your new NH Medicaid Provider ID

A change of ownership requires a new NH Medicaid enrollment application within 35 days of the change. An existing application can't be amended, because Medicaid NH provider enrollment doesn't survive a sale.

NH Medicaid counts four events as a change of ownership.

• Adding an owner
• Removing an existing owner
• Changing the Tax ID
• Changing controlling interest, direct or indirect, including board members or managing employees

NH Medicaid processes thenew application with a new Medicaid ID and a new effective date, and end-dates the old Medicaid ID the day before the change took place.

Notify the state late and NH Medicaid runs a claims check instead. The old ID gets end-dated on the last paid claim date, and the new ID starts the next day.

Say a practice completes a sale on October 31. Submit the new ownership application inside 35 days with no claims billed in between, and the new Medicaid Provider ID is effective October 31.

Miss that window and keep billing under the old ID, and the new effective date falls after your last paid claim date. Everything between those two dates is unbillable.

One clause buyers overlook: whoever replaces a provider accepts liability alongside the predecessor for overpayments NH Medicaid seeks to recover after the successor's effective date. That holds regardless of whether the buyer had any connection to the seller when the overpayment happened. Price it into the deal.

Bill under the new Provider ID as soon as the Welcome Letter arrives carrying it.

NH Medicaid revalidation in 2026: who gets selected and what happens if you miss it

All enrolled NH Medicaid providers must revalidate at least every five years under Section 6401 of the Affordable Care Act. New Hampshire Medicaid provider enrollment doesn't stay active on its own.

The standard five-year cycle

NH Medicaid began ongoing five-year revalidations in June 2017 and runs the process online through the MMIS portal. Notices go to the mailing address on the Medicaid ID record and post to your MMIS Message Board, with email notification where NH Medicaid holds a current address.

Revalidation covers every provider type: group, individual, billing, rendering, and ORP. Three operational rules catch people out.

• Revalidate each Medicaid ID inside each MMIS portal account. NH Medicaid generates letters from each ID's original enrollment date or its last accepted revalidation, which puts multiple IDs on separate due dates.
• An individual provider completes one revalidation per individual provider number, whatever the number of groups they're affiliated with.
• Out-of-state providers who already revalidated with their home state still revalidate with NH Medicaid. Practices runningmulti-state telehealth credentialing hit this in several states at once.

What the 2026 accelerated initiative changes

NH Medicaid is running accelerated provider revalidations under the federal CMS initiative announced April 23, 2026. Many providers will be asked to revalidate earlier than their usual five-year anniversary.

The MMIS portal won't let you start until NH Medicaid selects your provider number for revalidation, so watching for the notice matters more than watching the calendar. Records carrying a stale mailing address are the ones that miss it.

The 60-day window and no extensions

Providers have 60 days from the date of the first revalidation letter to complete and submit.NH Medicaid sends notice 60 days out, again at 30 days, and once more on the due date.

Extensions are not granted. NH DHHS points to 42 CFR 455.104(c) and 42 CFR 455.450 as the reason, so there's no discretion for a call center agent to exercise on your behalf.

Claims may be suspended if revalidation isn't completed, followed by termination of enrollment. Termination costs far more than the lapse. Re-enrolling means a new application, a new Medicaid Provider ID, and re-enrolling with all three managed care plans from scratch.

Suspended claims don't disappear. They age. A revalidation lapse converts current-period revenue into aged receivable, andrecovering aged AR collects at a lower rate the longer it sits.

Managed care recredentialing does not count

Recredentialing with a NH Medicaid managed care plan does not satisfy NH Medicaid revalidation. The two processes are separate, and finishing one leaves the other wide open.

Run the arithmetic. AmeriHealth Caritas New Hampshire re-credentials practitioners at least every 36 months. NH Medicaid revalidates every 60 months. Those cycles never line up, which is why providers assume they've handled it when they haven't. Complete both.

MedSole RCM tracks revalidation dates for every enrolled provider and files through the MMIS portal before the 60-day window closes, as part of itsrevalidation tracking service.

NH Medicaid provider contacts and next steps

Provider contacts

No commercial page on this topic publishes the NH Medicaid provider phone number alongside the rest of the routing, so here it is in one place.

Member contacts

Providers use (603) 223-4774 or (866) 291-1674. Members use 1-844-ASK-DHHS. Mixing them up costs a transfer and a hold.

The NH Medicaid phone number members need is DHHS Customer Service at 1-844-ASK-DHHS (1-844-275-3447), Monday through Friday, 8:00 a.m. to 4:00 p.m. ET. For health plan questions, the Medicaid Service Center answers at 1-888-901-4999 on the same schedule.

Note the difference in hours. The provider lines run to 5:00 PM EST and the member lines close at 4:00 p.m. ET, which is why a late-afternoon call to the wrong number goes nowhere.

Working with MedSole RCM

MedSole RCM handles New Hampshire Medicaid provider enrollment at $99 per payer per provider and full-cyclemedical billing at 2.99 percent of collections, with no setup fees, no annual contracts, and no hidden charges.

Outsourced payer enrollment in the US market runs $150 to $300 per payer per provider, and full-service revenue cycle management runs 4 to 9 percent of collections. The comparison is arithmetic, not a claim about anyone else's service.

We file the NHMMIS application, credential with all three New Hampshire managed care plans in parallel, configure EFT and ERA, and track revalidation dates so the enrollment doesn't lapse.

Practices call us for one of two reasons: an application that stalled somewhere they can't see, or a revalidation letter that showed up with 60 days on it. Both are fixable, and the second one is fixable faster than most people expect.

Frequently asked questions about New Hampshire Medicaid provider enrollment

How do I enroll as a NH Medicaid provider in 2026?

Enrollment runs online through the New Hampshire MMIS Health Enterprise Portal at nhmmis.nh.gov. Open the Provider tab, select Enrollment, choose one of the four provider application types from the Become a Provider page, complete ownership disclosures, upload your documents, and record the Application Tracking Number. No downloadable form exists.

How long does New Hampshire Medicaid provider enrollment take?

NH Medicaid publishes no standard processing timeline. The state says processing depends on provider type, the individuals associated with the application, and whether the file was complete and accurate at submission. NH DHHS does set managed care deadlines: 30 calendar days for primary care credentialing and 45 calendar days for specialty care.

How do I check my NH Medicaid application status?

Go to the Provider tab in NHMMIS and select Enrollment, find the Application Status box on the right-hand side, enter your Application Tracking Number, and click Submit. The Application Tracking Number is the only way to check status. No lookup by name, NPI, or Tax ID exists.

What is the phone number for NH Medicaid provider enrollment?

Call (603) 223-4774 or (866) 291-1674, Monday through Friday, 8:00 AM to 5:00 PM EST. That's the NH Medicaid Provider Enrollment and Provider Relations line, staffed by Conduent as fiscal agent. Members call 1-844-ASK-DHHS (1-844-275-3447) instead, 8:00 a.m. to 4:00 p.m. ET.

Which NH Medicaid enrollment application do I need?

NH Medicaid offers four provider applications: Billing Group under an FEIN, Billing Individual under an SSN, Non-Billing Rendering, and Non-Billing ORP. A fifth track, Trading Partner, covers electronic data exchange. The Billing Individual application already covers rendering, ordering, and prescribing.

Do I need to enroll separately with NH Medicaid managed care plans?

Yes. Providers seeing only fee-for-service members need state enrollment alone. Anyone treating Medicaid Care Management members enrolls with the state, then contracts and credentials with AmeriHealth Caritas New Hampshire, NH Healthy Families, and WellSense Health Plan. You can start MCO applications before state approval, but can't complete them until NH Medicaid issues your provider ID.

Is there an NH Medicaid provider enrollment form PDF?

No. NH Medicaid has no downloadable provider enrollment form, and the application is completed online in NHMMIS. Supporting PDFs do exist, including the Provider Participation Agreement, the Enrollment and Revalidation Signature Page, the EFT Agreement, the ERA Enrollment Application, and the Change of Information Form.

How often do NH Medicaid providers have to revalidate?

At least every five years, under Section 6401 of the Affordable Care Act. Providers have 60 days from the date of the first revalidation letter to complete and submit. Extensions are not granted. NH Medicaid is running accelerated off-cycle revalidations in 2026 under a federal CMS initiative.

How much does NH Medicaid provider enrollment cost?

The CY 2026 federal application fee is $750 for institutional providers, effective January 1 through December 31, 2026. Physicians and non-physician practitioners are exempt. MedSole RCM handlesNH Medicaid enrollment at $99 per payer per provider, against a US market range of $150 to $300 per payer per provider.

Do ordering and prescribing providers have to enroll in NH Medicaid?

Yes, for fee-for-service claims. Under 42 CFR 455.410, an ORP provider listed on a fee-for-service claim must be enrolled in NH Medicaid, and their NPI must appear on the claim. The requirement doesn't extend to claims submitted to the three Medicaid Care Management plans.

What happens to my NH Medicaid Provider ID if my practice is sold?

NH Medicaid enrollment is not transferable and terminates on sale or transfer of ownership. A change of ownership requires a new application within 35 days. NH Medicaid issues a new Medicaid ID with a new effective date, and end-dates the old ID the day before the change took place.

Does managed care recredentialing count as NH Medicaid revalidation?

No. Recredentialing with a NH Medicaid managed care plan does not satisfy NH Medicaid revalidation. AmeriHealth Caritas New Hampshire re-credentials at least every 36 months while NH Medicaid revalidates every 60 months, so the two cycles fall on different dates. Complete both.
