General Surgery CPT Codes: The 2026 Reference for Surgeons and Billing Teams

General surgery CPT codes are the Current Procedural Terminology codes in the CPT Surgery section, 10004-69990, that general surgeons use to report procedures across the digestive, integumentary, endocrine, hemic, lymphatic, and respiratory systems.

This guide lists the general surgery CPT codes your practice bills most, with the detail most reference pages leave out: the global period on each one. It also flags the hernia codes CPT deleted in 2023 that competitors still publish as current.

You'll also find what the 2026 Medicare fee schedule did to surgical work RVUs. Every code traces back to the AMA CPT code set, the American College of Surgeons coding bulletins, or CMS. Where a figure comes from a CMS rule, we name the rule.

What Is the CPT Code Range for General Surgery?

The CPT Surgery section runs 10004 to 69990. General surgeons bill across most of it, though the heaviest volume sits in the digestive system range, 40490-49999.

Why You Still See 10021 Listed as the Starting Code

Plenty of published guides still open with 10021. That figure is seven years stale. Before CPT 2019, code 10021 sat at the front of the Surgery section. The AMA restructured the fine needle aspiration family that year, added codes 10004 through 10012, and moved the section start to 10004.

If a page says general surgery CPT codes begin at 10021, it's describing a code set that retired in 2018. Check the publication date before you trust anything else on it.

General Surgical Procedures (10004-10021) vs Integumentary (10030-19499)

Two separate subsections open the Surgery section, and most guides collapse them into one. Codes 10004 through 10021 are General Surgical Procedures, which is the fine needle aspiration biopsy family. Codes 10030 through 19499 are the Integumentary System, covering skin, soft tissue, and breast.

The AMA maintains the full code set and updates it each year. Confirm the current structure against the AMA CPT code set before you rebuild a picklist.

CPT Surgery Section Code Ranges by Body System

A surgeon doing breast, thyroid, and abdominal work pulls from four of these ranges in a single week. Build your charge master by service line rather than by one range, or you'll miss the endocrine and lymphatic codes.

The Most Common General Surgery CPT Codes

Appendectomy, cholecystectomy, hernia repair, and colectomy account for most of the operative volume in a general surgery practice. These 15 general surgery CPT codes show up on more claims than the rest of the section combined, and each one carries its global period below.

Top 15 General Surgery CPT Codes by Volume

How to Read the Global Period Column

The three digits tell you how long the payment already covers postoperative care. A 000 code pays for related care on the day of the procedure only. A 010 code carries a 10-day postoperative window. A 090 code carries one preoperative day, the day of surgery, and 90 days after.

Approach drives code selection more than any other single factor. The same organ, removed two ways, gets two codes and two payment amounts. Your operative note has to say open, laparoscopic, or converted, in those words. Other specialty guides here follow the same structure, including the ophthalmology CPT code guide.

Appendectomy CPT Codes

Four codes cover appendectomy, and two of them get mixed up more often than any others. The distinction turns on approach and on whether the appendix came out as the main event or alongside another operation.

Appendectomy CPT Codes and Global Periods

When to Use 44955 Instead of 44950

Code 44950 is a standalone open appendectomy. It isn't the incidental code. When a surgeon removes the appendix for a separate indicated reason during another major abdominal operation, the correct code is add-on 44955.

A normal appendix taken on the way past during other surgery isn't separately payable at all. Several published guides still list 44950 as the incidental code, and practices following them collect denials and audit exposure together.

Ruptured Appendix and the 44960 Trap

The laparoscopic code doesn't change when the appendix ruptures. Code 44970 covers the straightforward case and the perforated one. Payers reject 44960 on a laparoscopic case, because 44960 describes an open procedure.

If the perforation made the case harder, that's a modifier 22 conversation. It needs documented operative time against the typical, plus the findings that created the extra work. It isn't a code change.

Cholecystectomy CPT Codes

Gallbladder removal is the highest-volume operation most general surgeons perform, and it is where approach documentation causes the most trouble. Code selection depends on how the surgeon got in, and on whether anything happened to the bile duct.

Cholecystectomy CPT Codes by Approach

ICG Fluorescence Is Not Cholangiography

Near-infrared indocyanine green imaging and a radiographic cholangiogram are two different services. Operative notes blur the two, and coders pick 47563 when the surgeon used ICG alone. Payers catch it and take the money back.

Code 47563 applies when contrast went in, somebody imaged the ducts, and somebody interpreted those images. If none of that happened, 47562 is correct. The note has to describe the imaging step apart from the removal, and it has to name who read the films, since the interpreting physician bills the supervision and interpretation component.

Mismatches between the procedure code and the modifier on the claim show up as CO-4 modifier denials, which is one of the most common rejections on biliary claims.

Coding a Laparoscopic Case That Converts to Open

When a laparoscopic case becomes an open one, report only the completed open procedure. Billing both approaches on the same claim produces a denial, and it shows up as a take-back on audit.

Intraoperative fluoroscopy, 76000, is typically inherent to the surgery and not separately payable. Adding it because the C-arm sat in the room is a habit worth breaking.

Hernia Repair CPT Codes After the 2023 Restructure

On January 1, 2023, CPT deleted 18 anterior abdominal hernia codes and replaced them with families priced by total defect length and clinical presentation. Mesh went into the base code. Three years later, several reference pages that rank on page one still publish the deleted set.

The retired codes are 49560, 49561, 49565, 49566, 49568, 49570, 49572, 49580, 49582, 49585, 49587, 49590, 49652, 49653, 49654, 49655, 49656, and 49657. The ACS anterior abdominal hernia changes bulletin published the full crosswalk, and the ACS 2023 CPT coding changes bulletin confirmed the effective date.

Inguinal and Femoral Hernia Repair CPT Codes

Anterior Abdominal Hernia: Sized by Total Defect Length

The replacement family covers ventral, incisional, umbilical, epigastric, and spigelian hernias in one structure. Code selection turns on three things: initial or recurrent, the total defect length, and whether the hernia was reducible or incarcerated.

Defect length means the total of all defects added together, not the largest one. A patient with three small fascial defects in a row can land in a higher payment tier than the biggest single defect would suggest, and the surgeon has to measure and dictate all of them.

Initial versus recurrent decides the other half of the code. Somebody has to confirm prior repair status from the chart before the claim goes out, because a recurrent repair billed as initial creates a history mismatch the payer can see.

Mesh Is Bundled and Not Separately Reportable

Old code 49568 covered mesh implantation as a separate line. It's gone. Mesh now sits inside 49591 through 49618, and payers deny a separate mesh charge on those claims.

One add-on survived. Code 49623 reports removal of non-infected mesh at the time of the repair. That is the only mesh line that still stands on its own in this family.

Parastomal Hernia and Mesh Removal Codes

Deleted general surgery CPT codes sitting in a charge master don't throw an obvious error. They come back as a rejection somebody reworks without ever tracing it to the code list, and the same rejection lands again next month.

Practices that would rather hand off the whole surgical claim path use general surgery billing services instead of rebuilding the picklist every CPT cycle.

Colectomy and Colorectal CPT Codes

Colectomy codes split on approach first, then on what the surgeon did with the two ends. Anastomosis, colostomy, coloproctostomy, and mucofistula each take a different code, and the descriptor has to match the operative note line for line. These are the general surgery CPT codes where a vague dictation costs the most.

Colectomy CPT Codes, Open and Laparoscopic

Splenic Flexure Mobilization Is a Separate Add-On

Mobilizing the splenic flexure during a partial colectomy earns its own add-on code, 44139 open and 44213 laparoscopic. Groups leave it off the claim more than any other add-on in colorectal work.

The fix sits with the surgeon rather than the coder. If the dictation says the flexure came down, your coder can add it. If the note skips the step, nobody downstream can put it back.

Hartmann Codes Already Include the Stoma

Codes 44143 and 44206 include creation of the end colostomy and closure of the distal segment. Adding a separate stoma code on top of either one triggers a bundling denial. Pick the colectomy code whose descriptor matches what happened, then stop.

Conversions follow the cholecystectomy rule. When a laparoscopic colectomy becomes open, report the completed open procedure and drop the laparoscopic code.

Colonoscopy and Sigmoidoscopy Codes

Codes 45380 and 45385 separate on how the tissue came out. A cold or hot biopsy forceps takes 45380. A snare takes 45385. When the surgeon uses both techniques on different lesions in the same session, both codes apply with the right modifier.

Stomach and Small Bowel CPT Codes

Gastric and small bowel work runs on a short list of codes, and one of them gets mislabeled across published references often enough to matter. It's the add-on.

Stomach and Small Bowel CPT Codes

44120, 44121, and 44125 Describe Three Different Things

Code 44120 is a single small bowel resection with anastomosis. Code 44121 is the add-on for each additional resection and anastomosis in the same session, and it never stands alone. Code 44125 is a resection with enterostomy.

At least one page-one reference has all three of these mislabeled, describing 44121 as a standalone single resection. A practice copying that structure bills an add-on with no primary code, and the line rejects every time.

43889 Is New for 2026

Endoscopic sleeve gastroplasty got a Category I code for 2026. Code 43889 covers the transoral procedure including argon plasma coagulation when performed, sits in the Stomach and Other Procedures subsection, and carries a 90-day global period.

Thyroid and Endocrine Surgery CPT Codes

Code 60240 is total or complete thyroidectomy. It doesn't cover partial work, and several reference sources describe it as covering both. Partial and unilateral procedures use 60210, 60212, 60220, or 60225, and those four separate on extent and laterality.

Thyroidectomy CPT Codes: Partial vs Total

The trap sits between 60220 and 60240. A surgeon removing one lobe entirely performed a total lobectomy, which is 60220, not a total thyroidectomy. Billing 60240 for unilateral work overstates the procedure and invites a request for records.

Parathyroid and Adrenal CPT Codes

Nerve Monitoring Is Not Billable by the Operating Surgeon

Intraoperative nerve monitoring codes require an independent monitoring professional. The operating surgeon can't bill them, and adding them to the surgeon's claim produces a denial.

Diagnosis linkage carries its own weight on thyroid claims. Payers check whether the submitted diagnosis supports surgery on a gland, and our guide to thyroid ICD-10 pairing covers the codes that hold up under review.

Breast Surgery CPT Codes

Breast codes separate on imaging guidance for biopsies and on lymph node handling for mastectomies. Both splits produce predictable denials when the note leaves out a detail.

Breast Surgery CPT Codes

Sentinel Node Biopsy With a Full Axillary Dissection

When the mastectomy already includes axillary lymphadenectomy, as 19302 and 19307 do, sentinel lymph node biopsy stops being separately reportable. Billing both on one claim is a standard rejection.

The opposite error costs more. Intraoperative sentinel node mapping, 38900, is an add-on that gets missed when the surgeon performs a lumpectomy or a mastectomy without dissection. That's money the practice earned and never charged for.

One clarification on descriptors: 19302 is partial mastectomy with axillary lymphadenectomy. Axillary lymphadenectomy and sentinel node biopsy are two different services. A reference page that treats them as the same thing will walk your coder straight into the denial above.

Skin, Soft Tissue, and Debridement CPT Codes

General surgeons bill integumentary codes for abscess drainage, wound debridement, and lesion excision. Two sizing rules decide payment across this family of general surgery CPT codes, and both depend on a measurement the surgeon takes before cutting.

Skin and Soft Tissue CPT Codes Used in General Surgery

Lesion Excision Is Sized Before You Cut

Code selection uses the greatest clinical diameter of the lesion plus the narrowest margin required for complete excision. That measurement happens before the excision, not after. Specimens shrink in fixative, and a pathology report measurement will undersize the code.

Record the lesion size and the planned margins in the note before the first cut. Skip it and you'll lose the difference between 11602 and 11604 on every case, and you won't recover it on appeal.

Debridement Is Coded by Deepest Tissue Removed

Codes 11042 through 11047 turn on the deepest tissue the surgeon removed, then on total surface area. Subcutaneous tissue, muscle and fascia, and bone each get their own base code, with add-ons for each additional 20 square centimeters.

Exposing bone during a debridement doesn't make it a bone debridement. The surgeon has to remove bone before 11044 applies, and the note has to say so.

Lysis of Adhesions and Exploratory Laparotomy CPT Codes

Adhesiolysis is the most contested separately reportable service in abdominal surgery. Routine lysis bundles into whatever operation the surgeon was performing. Extensive lysis can stand on its own, and the operative note decides which one you've got.

Adhesiolysis and Exploratory Abdominal CPT Codes

When Adhesiolysis Is Separately Reportable

Both 44005 and 44180 carry the separate procedure designation, which means they bundle into any larger abdominal operation performed at the same session. Reporting them as routine produces bundling denials and draws audit attention toward the practice.

You can report extensive adhesiolysis, and the note has to earn it. Document the added operative time against a typical case, the extent of the dissection, and what made the adhesions unusual. A sentence saying the adhesions were dense isn't enough on its own.

Diagnostic Laparoscopy Bundles Into the Definitive Procedure

Code 49320 bundles when a therapeutic laparoscopic procedure follows in the same session. Reporting 49320 next to 47562 without a supported modifier gets rejected under a National Correct Coding Initiative edit.

A modifier can override that edit when the two procedures were distinct, and the documentation has to carry the argument. Our guide to modifier 59 NCCI rules walks through when the override holds up and when it creates exposure.

Liver, Pancreas, Spleen, and Vascular Access CPT Codes

Hepatobiliary and pancreatic resections are lower volume and higher value than the rest of the general surgery CPT codes on this page. Vascular access sits at the other end, high volume and miscoded more often than any other minor procedure in the specialty.

Liver, Pancreas, and Spleen CPT Codes

Code 47384 arrived for 2026 and replaced deleted Category III code 0600T for percutaneous irreversible electroporation of liver tumors. The move from Category III to Category I changes the money. Medicare pays Category I codes, while many Category III codes stay contractor priced or uncovered. The American College of Surgeons Bulletin documented the change when it took effect.

Central Venous Access CPT Codes

Four questions decide the access code: tunneled or not, port or no port, central or peripherally inserted, and patient age above or below five years. Get one wrong and the claim pays at the wrong rate rather than denying, which is why these errors run for months before anybody notices.

Global Surgical Periods in General Surgery

Most of the major general surgery CPT codes carry a 090 global indicator, which covers one preoperative day, the day of surgery, and 90 days after. Minor procedures carry 010 or 000. The indicator sits on every code in the Medicare Physician Fee Schedule, and it decides what you can bill separately for three months after the operation.

Medicare Global Surgery Indicators

How Medicare Counts the Days

A 090 procedure spans 92 days in total. One day before surgery, the day of surgery, and the 90 days that follow. A 010 procedure spans 11 days: the day of the procedure and the 10 days after it.

That arithmetic matters when somebody schedules a post-op visit on day 91 and your system flags it as global. Put the global end date on the schedule and in the billing worklist, and the accidental write-offs stop.

What the Global Package Already Pays For

CMS bundles a defined list into the surgical payment. The CMS Global Surgery Booklet spells it out, and the December 2025 edition is the current one.

• Preoperative visits after the decision for surgery
• Intraoperative services that are a usual part of the procedure
• Postoperative visits related to recovery from the surgery
• Postsurgical pain management by the surgeon
• Dressing changes, suture and staple removal, and drain removal
• Complications that do not require a return trip to the operating room

Transfer of Care: Modifiers 54, 55, and 56

When one physician operates and another handles the postoperative care, both report the same CPT code with the same date of service, and each appends a split-care modifier. Modifier 54 covers surgical care only, 55 covers postoperative management only, and 56 covers preoperative care only.

Three rules trip people up here. Split care doesn't apply to 000 codes at all. The receiving physician has to furnish at least one service before billing any part of the postoperative care. And neither 54 nor 55 applies to assistant-at-surgery services or to ambulatory surgery center facility fees.

CMS also widened modifier 54. It now covers any case where the surgeon plans to provide only part of the global package, including an informal transfer that nobody documented in a formal agreement. The Medicare Claims Processing Manual carries the day-counting examples in Chapter 12.

Tracking a 90-day window per patient per procedure across a busy surgical schedule turns into an operational system rather than a lookup. Practices that want that handled alongside coding use surgical billing by specialty instead of building the tracker themselves.

Billing E/M Visits Inside the Global Period

Routine postoperative visits inside the global window are already paid for, and you report them with 99024. It's a zero-dollar tracking code. Skipping it costs nothing today, and it costs the specialty later, because CMS uses 99024 reporting data to revalue the global codes themselves.

CPT 99024 and Why You Still Report It

Under-reporting postoperative visits makes surgical work look lighter than it is when CMS reviews global code valuation. Surgeons who skip 99024 are handing the agency an argument for lower work RVUs on the codes they bill most.

Modifier 24 for an Unrelated Visit

Modifier 24 identifies an E/M during the postoperative period for a problem unrelated to the surgery. The diagnosis on that claim has to support the word unrelated. Submit modifier 24 with the same diagnosis as the surgery and the payer denies it.

Modifier 57 Applies to Major Surgery Only

Modifier 57 marks the E/M visit where the surgeon made the first decision to operate, the day before or the day of a major procedure. It applies to major surgery only and never to minor procedures.

For a minor procedure, modifier 25 is the correct choice when the E/M was significant and separately identifiable. Our guides to CPT 99211 billing rules and new patient E/M coding cover the documentation each level needs.

E/M Modifiers Inside the Global Period

Modifier FT covers critical care visits that are unrelated to the surgical procedure and furnished after it. CMS added it to the Global Surgery Booklet, and almost nobody in general surgery uses it.

Code G0559 covers postoperative care furnished within the global period by a practitioner who didn't perform the surgery. Practices where a hospitalist or an advanced practice provider handles follow-up should have this on the charge sheet.

Surgical Modifiers That Decide Whether a Claim Pays

Modifiers carry more payment weight on general surgery CPT codes than on anything a cognitive specialty bills. Two of them start a new global period, one pays only the intraoperative portion, and one overrides a bundling edit. Getting them confused costs real money on high-value claims.

Surgical Modifiers Used in General Surgery

Modifier 58 vs 78 vs 79

These three look identical on an operative note and pay in three different ways. Modifier 58 covers a staged or related procedure the surgeon planned at the time of the first operation, and it starts a fresh global period.

Modifier 78 covers an unplanned return to the operating room for a complication of the original surgery. It pays the intraoperative portion only, and the original global period keeps running underneath it.

Modifier 79 covers a procedure unrelated to the first one during the global window. It pays in full and starts a new global period. The diagnosis has to carry the word unrelated, same as modifier 24.

Modifier 22 and the Documentation It Needs

Modifier 22 is an exception, not a routine append. Some published code tables assign it to entire procedure families, which is wrong and any surgeon reading one will notice.

The note has to quantify the extra work: added operative time against the typical case, the extent of adhesions or scarring, patient factors that changed the difficulty, and any anatomical variation the surgeon encountered.

Modifier 51 and Modifier 59 Are Not Interchangeable

Modifier 51 tells the payer that multiple procedures happened in one session, and the payer reduces payment on the secondary ones. Modifier 59 overrides a National Correct Coding Initiative edit when two procedures were separate services.

Misusing 59 is the single most reliable way to attract an audit in surgical billing. The X modifiers, XE, XS, XP, and XU, give you a more specific override when one fits. Our distinct procedural service guide covers where the override survives review.

Modifier 50 and Bilateral Procedures

Check the bilateral surgery indicator before you append modifier 50. Some CPT descriptors already describe a bilateral procedure, and adding 50 to one of those produces an overpayment that the payer recoups later.

Assistant Surgeon and Co-Surgeon Billing

An assistant surgeon helps the primary surgeon complete one procedure. A co-surgeon performs a distinct portion of the same procedure. Different roles, different modifiers, different payment math.

Assistant Surgeon and Co-Surgeon Modifiers

Why AS Alone Gets a Claim Returned

Modifier AS never travels alone. When a physician assistant, nurse practitioner, or clinical nurse specialist assists at surgery, the claim carries AS and one of 80, 81, or 82. Submit AS by itself and Medicare returns the claim to the provider.

That single rule accounts for a steady share of assistant-at-surgery rejections, and it takes one edit in your claim scrubber to eliminate.

Modifier 62 for Co-Surgeons

Two surgeons reporting modifier 62 submit the same CPT code on the same date. Each one documents the distinct portion they performed, and each gets paid a share of the fee schedule amount rather than the full value.

Both operative notes have to describe separate work. A note saying the second surgeon assisted turns a co-surgeon claim into an assistant claim, and the payer will price it that way.

Check the Assistant-at-Surgery Indicator First

Medicare publishes a payment policy indicator for every code that tells you whether an assistant is payable at all. Plenty of codes never support one, no matter how good the documentation is. Confirm the indicator before the claim drops rather than after the denial arrives.

Enrollment sits underneath all of this. An assistant who isn't credentialed and contracted with the payer can't be paid as an assistant no matter which modifier you append, and the same holds for the operating surgeon.

The general surgery taxonomy code is 208600000X, and it has to match across the NPI record, the payer file, and the claim. A mismatch there blocks payment before anybody looks at the procedure code. MedSole RCM handles provider enrollment and credentialing at $99 per payer enrollment.

NCCI Edits, Bundling, and MUE Limits

The National Correct Coding Initiative defines which code pairs you can't report together and which comprehensive code already includes the other. Most surgical bundling denials trace back to one of these edits.

What NCCI Bundles in General Surgery

• Diagnostic laparoscopy reported with a therapeutic laparoscopic procedure
• Routine adhesiolysis reported with any larger abdominal operation
• Exploratory laparotomy reported with a definitive intra-abdominal procedure
• Simple closure reported with a lesion excision
• Intraoperative fluoroscopy reported with the procedure it guided

The Quarterly Cadence Most Practices Miss

CMS updates the NCCI Policy Manual once a year, effective January 1. The edit files change four times a year, effective January 1, April 1, July 1, and October 1. The version in effect since January 1, 2026 is PTP version 32.0.

Most practices refresh CPT every January and never touch their claim edits again until the following January. Three quarterly updates go by, the scrubber falls behind, and the write-offs start. The CMS NCCI Policy Manual states the cadence in its introduction.

Three Modifiers That Do Not Bypass a PTP Edit

Only NCCI-associated modifiers override a procedure-to-procedure edit. Modifiers 22, 76, and 77 aren't on that list, and appending one of them to force a bundled pair through does nothing except delay the denial.

Medically Unlikely Edits and Unit Caps

A Medically Unlikely Edit caps the units of a code you can report for one patient on one date of service. Exceeding the cap produces a line-item rejection rather than a full claim denial, which is why these go unnoticed for months.

Each MUE carries an adjudication indicator. An MAI of 2 is an absolute limit for the date of service, and those denials aren't appealable. Checking the MUE value before submission is the only remedy. Services the payer treats as not separately payable land as CO-234 bundling denials.

Why General Surgery Claims Get Denied, by Denial Code

Eight claim adjustment reason codes account for most denials on general surgery CPT codes. The table maps each one to the cause that produces it in general surgery, and to the first thing your team should do about it.

Common Denial Codes on General Surgery Claims

CO-97 Is the Bundling Denial

CO-97 means the payer considers the service already paid inside another procedure on the claim. Resubmitting the same lines changes nothing. Either a modifier is supported by the documentation, or the service was correctly bundled and the appeal will fail. Our CO-97 denial guide covers both paths.

CO-50 Is a Medical Necessity Problem

On surgical claims, CO-50 usually means the diagnosis submitted isn't on the payer covered list for that procedure, or the record doesn't show the failed conservative treatment the policy requires. Pull the local coverage determination before drafting anything. Our CO-50 medical necessity denials guide walks the appeal.

CO-4 Is a Modifier Problem

CO-4 says the procedure code and the modifier don't agree, or a required modifier never made it onto the line. In general surgery that means laterality most of the time, or a missing 59, 58, or 79.

Denials repeat because nobody fixes what caused them. A practice can rework the same CO-97 every month for a year without ever changing the bundling rule in the scrubber that produces it. Root-cause denial management works the pattern rather than the individual claim, and MedSole RCM prices it at 4.49% of what gets recovered.

Prior Authorization and Timely Filing on Surgical Claims

When the Authorization Does Not Match the Code Billed

Somebody obtains authorization for a planned procedure. In the operating room the surgeon finds something different, does more than planned, and the code on the claim no longer matches the code that was approved. The payer returns CO-197 and the practice appeals blind.

Rescheduling causes the other version. The authorization expires before the new surgery date, nobody re-checks it, and the claim goes out against a dead approval. Both patterns show up in our CO-197 authorization denials guide.

Aged Surgical Claims and the 90-Day Global Trap

A 90-day global period means postoperative care keeps running long after the surgical claim went out. If that claim denied at submission and nobody worked it, the practice can be three months into follow-up on an operation it was never paid for.

Aging buckets and filing deadlines don't pause for the global period. Surgical claims carry high dollar values, so a handful sitting past 90 days does more damage than a hundred office visits. Accounts receivable recovery works them by recovery odds rather than by age alone.

Operative Report Documentation That Supports the Code

Most undercoding in general surgery starts with a note that doesn't say what the coder needs. The surgeon performed the work. The documentation left out the one detail that would have justified the higher code.

What Every General Surgery Operative Note Needs

Documentation That Justifies Modifier 22

Modifier 22 triggers manual review, so the note has to make the argument without anybody on your team adding to it. Quantify the added operative time. Describe the adhesions, the scarring, or the anatomy that created the extra work.

Reviewers see the word difficult on hundreds of claims a week and it moves nothing. They see 140 minutes against a typical 75, with three prior laparotomies named in the history, and the claim gets a second look.

CPT 2026 Changes That Affect General Surgery

CPT 2026 carried 418 editorial changes in total: 288 new codes, 84 deletions, and 46 revisions, all effective January 1, 2026. Five of them land on general surgery CPT codes your practice already bills.

43889: Endoscopic Sleeve Gastroplasty

Code 43889 reports transoral endoscopic sleeve gastroplasty, including argon plasma coagulation when performed. The AMA placed it in the Stomach and Other Procedures subsection and assigned it a 90-day global period.

47384: Liver Ablation Moves From Category III to Category I

The AMA deleted Category III code 0600T and established 47384 for percutaneous irreversible electroporation of one or more liver tumors, including imaging guidance. It carries a 0-day global period.

The category change is the part that matters financially. Medicare pays Category I codes. Category III codes stay contractor priced, and plenty of payers never cover them at all. A hepatobiliary program running IRE has been leaving money on the table and can stop.

Lower Extremity Revascularization Rebuilt From the Ground Up

The AMA deleted codes 37220 through 37235 and replaced them with 46 new codes organized into four vascular territories and split by lesion type. A stenosis counts as a straightforward lesion. An occlusion counts as a complex one.

The new codes bundle everything: access, selective catheterization, crossing the lesion, the intervention itself, all intraprocedural imaging with supervision and interpretation, and closure of the arteriotomy. All of them are unilateral.

For a bilateral primary procedure, append modifier 50. Don't append it to an add-on code carrying a ZZZ global assignment; report that add-on twice instead. Pull 37220 through 37235 out of the charge master before the next batch goes out.

TEVAR Bundling Changes

Thoracic endovascular aortic repair got restructured three ways for 2026. Catheter placement, radiologic supervision and interpretation, and proximal extensions performed at the time of TEVAR all bundle into the main procedure now.

A new code covers the distinct work of a thoracic branch endoprosthesis, and it includes the full work of a TEVAR. Separate codes for extra-anatomic bypass performed alongside TEVAR no longer exist.

Peritoneoscopy Removed From Every Laparoscopy Descriptor

The AMA stripped the term peritoneoscopy from every instance in the CPT code set for 2026. The word had been sitting in parentheticals and guidelines since 1996, when the AMA removed it from the descriptors themselves.

Check your operative note templates. A template still producing the word peritoneoscopy creates a mismatch between the documentation and the code descriptor, and payer automated review systems flag exactly that. The ACS coding and billing resources page carries the full change list for surgeons.

What the 2026 Medicare Fee Schedule Means for Surgical Reimbursement

CMS released the CY 2026 Physician Fee Schedule final rule on October 31, 2025, effective January 1, 2026. For the first time in Medicare history, surgeons are working under two conversion factors instead of one.

Two Conversion Factors for the First Time

CMS set the 2026 conversion factor at $33.57 for qualifying alternative payment model participants and $33.40 for practitioners who are not qualifying APM participants. Both rise from the CY 2025 conversion factor of $32.3465, by 3.77% and 3.26% respectively.

Three pieces built those numbers: statutory updates of 0.75% for APM qualifying participants and 0.25% for everybody else, a 2.5% update enacted in the One Big Beautiful Bill Act of 2025, and a budget neutrality adjustment of 0.49%. The CMS 2026 Physician Fee Schedule final rule fact sheet lays out the math.

The Efficiency Adjustment Takes Some of It Back

CMS finalized a negative 2.5% efficiency adjustment applied to the work RVUs and the intraservice portion of physician time for non-time-based services. In its own announcement, CMS named surgical procedures first among the service types affected.

A general surgery practice therefore sees a higher conversion factor multiplied against a lower work RVU on most of its operative codes. The headline increase and the number that lands in the bank aren't the same figure. The Federal Register CY 2026 payment policies entry carries the finalized rule text.

Several categories escaped the adjustment: time-based codes, E/M office visits, codes on the telehealth list, maternity care, and the new codes effective January 1, 2026. That last exemption is why 43889 and 47384 came in at full value. The AMA on the 2026 fee schedule analysis covers the specialty-level impact.

G0559 for Postoperative Care by Another Practitioner

CMS added G0559 for postoperative care furnished inside the global period by a practitioner who did not perform the surgery. If a hospitalist, a partner from another group, or an advanced practice provider handles your follow-up, this code belongs on the charge sheet.

Rate changes hit every surgical specialty differently, and the same pattern shows up in our guide to pathology CPT and Medicare rates for practices running a lab alongside the OR.

Deleted, Replaced, and Commonly Mislabeled General Surgery Codes

Three groups of general surgery CPT codes cause more rejections than any other coding error. Codes deleted in 2023 that reference sites still publish. Codes deleted in 2026 that remain in charge masters. And codes that are live but described wrongly across the industry.

Deleted and Replaced General Surgery CPT Codes

Codes That Are Live but Described Wrongly

Run these two tables against your charge master this quarter. A retired code produces a rejection your team reworks without tracing the cause, and it lands again on the next claim carrying that code.

CPT 2027 Changes Coming to General Surgery

The AMA released the CPT 2027 code set on September 9, 2026. It carries 453 editorial changes: 299 new codes, 74 revisions, and 80 deletions, all effective January 1, 2027. For general surgery, the headline is nine new codes for diaphragmatic hernia repair.

What the AMA Confirmed in the 2027 Release

The 2027 set retires the long-standing global maternity care bundle and replaces it with a framework built around team-based obstetric practice. It adds three codes for left ventricular assist device procedures, updates prostate biopsy guidelines, moves biofeedback to a time-based structure, adds new radiology tables, and adds six codes for unattended sleep studies.

Ten new codes describe artificial intelligence services, which brings the total count of AI-related CPT codes to 43.

Nine New Diaphragmatic Hernia Repair Codes

The nine new codes expand reporting across open, laparoscopic, and thoracoscopic approaches for traumatic and non-traumatic presentations. An add-on code covers mesh implantation with diaphragmatic hernia repair. Existing codes 39540 and 39541 get revised to specify via laparotomy.

A separate new code reports thoracoscopic plication of the diaphragm for eventration or paralysis, and 39545 gets revised to identify the open plication.

The operational gain is real. A surgeon performing laparoscopic or thoracoscopic diaphragmatic hernia repair has been reporting unlisted code 39599 or approximating with something else. Unlisted codes are contractor priced, which means documentation review and delayed payment on every single case.

Accepted CPT 2027 Changes Affecting General Surgery

One flag for wound care programs: codes 15011 through 15018 go away on January 1, 2027. Any reference guide leading with them as current is months from obsolete, and any charge master carrying them needs a retirement date on it.

Why You Cannot Load 2027 Codes Yet

The five-digit numbers aren't public. CPT descriptors stay proprietary to the AMA until the CPT Professional codebook publishes, and the 2027 edition arrives in the fall.

Until then, the Editorial Panel's accepted changes circulate as placeholder strings that look like 39XX3, 44XX1, or 15X19. Those aren't billable codes and no payer will accept one. A reference guide listing them as if they were codes is republishing a panel summary without understanding what it is looking at.

Four things a practice can do in the weeks before January 1. Pull a report of every case you currently bill under unlisted 39599. Flag 15011 through 15018 in the charge master for retirement. Put the codebook publication date on the fourth-quarter calendar. Schedule coder training for December rather than January, when the new codes are already live.

Last verified September 17, 2026. This section gets updated when the AMA publishes the CPT Professional 2027 codebook and the five-digit codes become available.

Which General Surgery CPT Codes Are Surgical and Which Are Diagnostic?

Not every code in the CPT Surgery section describes a therapeutic operation. Several codes between 10004 and 69990 report diagnostic procedures, and most of those carry a 0-day global period rather than a surgical one.

Surgical vs Diagnostic Codes in the CPT Surgery Section

Codes 43235 and 43239 are the pair coders confuse most. Code 43235 covers a diagnostic upper endoscopy with washing or brushing, and no tissue comes out. The moment the surgeon takes a biopsy, 43239 applies instead, and you never report both for the same session.

Code 49000 is the odd one. It describes an open exploratory laparotomy and carries a 90-day global period, but it bundles into any definitive intra-abdominal procedure performed in the same session. Practices running several service lines can pick up specialty-specific coding support for the codes that behave this way.

General Surgery CPT Codes That Get Confused

Six groups of general surgery CPT codes produce most of the selection errors in this specialty. Each one turns on a single detail in the operative note.

Commonly Confused General Surgery CPT Code Pairs

Forward-year changes matter on these pairs too, and our ABA CPT 2027 changes guide shows how a confirmed code restructure reshapes a specialty picklist before the effective date arrives.

Do Medical Billing Services Cover General Surgery CPT Codes?

Yes. A surgical billing team works general surgery CPT codes across the full claim path, from verifying benefits before an elective case through recovering the balance after a denial. What separates a surgical billing team from a general one is global period tracking and modifier discipline.

What Surgical Billing Scope Covers

• Eligibility and benefits verification, plus prior authorization on elective cases
• Operative report review and code assignment across the surgery ranges
• Modifier application and global period tracking by patient and date
• Assistant surgeon and co-surgeon claim coordination
• Charge entry, clean claim submission, and payment posting against contracted rates
• Denial management by reason code and accounts receivable follow-up by aging bucket
• Provider credentialing and payer enrollment

In-House or Outsourced for a Surgical Practice

A surgical practice running one or two billers carries concentration risk. When that biller leaves, global period tracking and denial work stop first, because those are the tasks easiest to defer when somebody is covering two jobs.

Volume-driven specialties feel that faster than E/M-driven ones. A single 090 code sitting unworked is worth more than a week of office visits, and the filing clock runs the same either way.

What General Surgery Billing and Credentialing Cost

MedSole RCM charges 2.99% of collections for full-service revenue cycle management and $99 per payer for provider enrollment and credentialing. Published market pricing for outsourced medical billing runs 4% to 10% of collections, and per-payer credentialing commonly runs $150 to $500.

The 2.99% covers eligibility verification, coding review, clean claim submission, payment posting, denial management, accounts receivable follow-up, and monthly reporting. No setup fee, no per-claim charge, and no long-term contract. Denial management comes included at that rate, or runs standalone at 4.49% of what gets recovered.

Credentialing carries its own weight in surgery. A surgeon who isn't enrolled and contracted can't be paid for a single code on this page, and an unenrolled assistant can't be paid as an assistant regardless of the modifier. MedSole RCM runs both under one team, and you can see the full scope on the full revenue cycle management page.

Surgical practices that want the claim path handled end to end use outsourced surgical claim management, and practices that only need the denial backlog worked use surgical denial recovery on its own.

General Surgery CPT Codes: Frequently Asked Questions

What is the CPT code range for general surgery?

The CPT code range for general surgery is 10004 to 69990, which is the full Surgery section of the CPT code set. General surgeons bill across most of it, with the heaviest volume in the digestive system range, 40490 to 49999. Codes 10004 through 10021 form the General Surgical Procedures subsection, and 10030 through 19499 form the Integumentary System. Reference pages listing 10021 as the starting code are describing the pre-2019 structure.

What are the most common general surgery CPT codes?

The most common general surgery CPT codes are 44970 and 44950 for appendectomy, 47562 and 47563 for laparoscopic cholecystectomy, 49505 and 49650 for inguinal hernia repair, 49591 through 49596 for anterior abdominal hernia repair, 44140 and 44204 for partial colectomy, 43239 for upper GI endoscopy with biopsy, 49000 for exploratory laparotomy, and 60240 for total thyroidectomy. Most carry a 90-day global period, which means one preoperative day, the day of surgery, and 90 days of postoperative care are already inside the payment. Approach drives selection across all of them, so the operative note has to state open, laparoscopic, or converted.

What is the difference between CPT 47562 and 47563?

The difference between 47562 and 47563 is whether the surgeon imaged the bile ducts during the same session. Code 47562 covers a laparoscopic cholecystectomy with no duct work. Code 47563 adds cholangiography, which means contrast went in, somebody imaged the ducts, and somebody interpreted those images. Both carry a 90-day global period. One caution that costs practices real money: indocyanine green fluorescence imaging isn't cholangiography. If the surgeon used ICG alone, 47562 is the correct code, and billing 47563 invites a refund request. The operative note also has to name who interpreted the images.

What is the difference between CPT 44950 and 44970?

The difference between 44950 and 44970 is approach. Code 44950 is an open appendectomy and 44970 is the laparoscopic version. Both carry a 90-day global period. Code 44970 covers the ruptured appendix as well as the straightforward case, so don't switch to 44960 on a laparoscopic case. Code 44960 describes an open procedure for a ruptured appendix with abscess or generalized peritonitis. Neither 44950 nor 44970 is the incidental appendectomy code. That one is add-on 44955, reported when the appendix comes out for a separate indicated reason during another major operation.

Which hernia repair codes were deleted in 2023?

CPT deleted 18 anterior abdominal hernia codes effective January 1, 2023: 49560, 49561, 49565, 49566, 49568, 49570, 49572, 49580, 49582, 49585, 49587, 49590, 49652, 49653, 49654, 49655, 49656, and 49657. Codes 49591 through 49596 replaced them for initial repairs, and 49613 through 49618 cover recurrent repairs, priced by total defect length and clinical presentation. Mesh implantation is bundled into those codes and is no longer separately reportable, which retired 49568. The only surviving mesh line is add-on 49623 for removal of non-infected mesh at the time of repair.

What global period applies to general surgery procedures?

Most major general surgery procedures carry a 090 global period, which covers one preoperative day, the day of surgery, and 90 days after, for 92 days total. Minor procedures carry 010, which is the day of the procedure plus 10 days, or 000, which covers the day of the procedure only. Add-on codes carry ZZZ and follow the global period of the primary procedure. Check the indicator in the Medicare Physician Fee Schedule before billing anything inside the window.

Can you bill an E/M visit during the 90-day global period?

You can bill an E/M visit during the 90-day global period when the visit is unrelated to the surgery, and the claim needs modifier 24 with a diagnosis that supports the word unrelated. Routine postoperative visits related to recovery are already paid for and get reported with 99024, a zero-dollar tracking code. Submitting modifier 24 with the same diagnosis as the surgery produces a denial. Modifier FT covers unrelated critical care furnished after the procedure, and G0559 covers postoperative care delivered by a practitioner who did not perform the surgery.

What is CPT 99024 and do you have to report it?

CPT 99024 reports a postoperative follow-up visit that falls inside the global period and relates to the original surgery. It pays nothing, which is why practices skip it. CMS uses 99024 reporting data to revalue global surgical codes, so under-reporting makes surgical work look lighter than it is when the agency reviews work RVUs on the codes surgeons bill most. Some states and practice sizes carry a mandatory reporting requirement. Treat it as a data obligation rather than a billing one, because the downstream effect lands on your own fee schedule.

Which modifier is used for an assistant surgeon?

Modifier 80 identifies an assistant surgeon, 81 identifies a minimum assistant surgeon, and 82 identifies an assistant when a qualified resident surgeon is unavailable. Modifier AS identifies a physician assistant, nurse practitioner, or clinical nurse specialist acting as assistant, and AS must be billed alongside 80, 81, or 82. Submitting AS on its own gets the claim returned to the provider. Modifier 62 is for co-surgeons, which is a different role.

What is the difference between modifier 58, 78, and 79?

Modifier 58 reports a staged or related procedure the surgeon planned at the time of the original operation, and it starts a new global period. Modifier 78 reports an unplanned return to the operating room for a complication of the original surgery, pays only the intraoperative portion, and leaves the original global period running. Modifier 79 reports a procedure unrelated to the first one during the global window, pays in full, and starts a new global period.

Is CPT 43235 a surgery code?

CPT 43235 sits in the Surgery section of the CPT code set, but it reports a diagnostic procedure rather than a therapeutic one. It covers a diagnostic upper gastrointestinal endoscopy including washing or brushing, with no tissue removed, and it carries a 0-day global period rather than a surgical one. If the surgeon takes a biopsy during the same session, report 43239 instead. The two are never billed together for one session. Several general surgery CPT codes behave this way, including 47000, 49320, and 52000.

What are the new CPT codes for 2026?

The new CPT codes for 2026 relevant to general surgery are 43889 for transoral endoscopic sleeve gastroplasty, which carries a 90-day global period, and 47384 for percutaneous irreversible electroporation of liver tumors, which carries a 0-day global period and replaced Category III code 0600T. The AMA also replaced codes 37220 through 37235 with 46 new territory-based lower extremity revascularization codes and restructured TEVAR reporting. CPT 2026 carried 418 changes in total.

Which CPT codes were deleted in 2026?

CPT 2026 deleted 84 codes. The deletions that matter to general surgery and related specialties are 37220 through 37235 for lower extremity revascularization, Category III code 0600T for liver irreversible electroporation, and codes 91120 and 91122 for colon motility studies. The AMA also removed the term peritoneoscopy from every laparoscopy descriptor, which is a descriptor change rather than a deletion, though it still creates a documentation mismatch if your operative templates carry the word. Pull the deleted revascularization codes from the charge master before the next claim batch goes out.

What is the 2026 Medicare conversion factor?

The 2026 Medicare conversion factor is $33.57 for qualifying alternative payment model participants and $33.40 for practitioners who are not qualifying APM participants. Both figures rise from the CY 2025 conversion factor of $32.3465. CMS also applied a negative 2.5% efficiency adjustment to work RVUs for non-time-based services, and named surgical procedures among the affected categories, so the net effect on a surgical practice is smaller than the conversion factor increase suggests.

What is the taxonomy code for general surgery?

The taxonomy code for general surgery is 208600000X, listed under Allopathic and Osteopathic Physicians in the NUCC taxonomy set. It has to match across the NPI record, the payer enrollment file, and the claim. A mismatch there blocks payment before anybody at the payer looks at the procedure code, and the rejection rarely names taxonomy as the cause. Do not confuse it with 207L00000X, which is anesthesiology. Verify the taxonomy on every new provider before the first claim goes out rather than after the first denial.

Do medical billing services cover general surgery CPT codes?

Yes. Surgical billing covers operative report review, code assignment across the surgery ranges, modifier application, global period tracking, assistant and co-surgeon claims, denial management by reason code, accounts receivable follow-up, and payer credentialing. MedSole RCM charges 2.99% of collections for full-service revenue cycle management and $99 per payer for provider enrollment and credentialing, with no setup fees and no long-term contract. Published market pricing runs 4% to 10% of collections for billing and $150 to $500 per payer for credentialing. Standalone denial management runs 4.49% of recovered revenue.
