CPT code 22902 – Abdominal wall soft tissue tumor excision

Key takeaways

CPT code 22902 covers excision of a subcutaneous abdominal wall soft tissue tumor that measures less than 3 cm, margin included.

Once the dissection breaches the fascia, the claim moves to 22900 or 22901, which use a 5 cm cutoff instead of 3 cm.

For 2026, 22902 carries 15.49 total RVUs in an office and 9.92 in a facility, about $517 and $331 before GPCI.

Each 22902 starts a 90-day global period, so routine follow-up visits for the excision are not billed separately.

Most 22902 denials trace back to an operative note that leaves the tissue layer or the measured size unclear.

What does CPT code 22902 cover?

CPT code 22902 covers excision of a subcutaneous soft tissue tumor of the abdominal wall that measures less than 3 cm. The official American Medical Association (AMA) descriptor reads: Excision, tumor, soft tissue of abdominal wall, subcutaneous; less than 3 cm.

Two qualifiers in that descriptor do the work. The tumor must sit above the fascia, and its size must stay under 3 cm. As the American College of Surgeons explains, size means the tumor’s greatest diameter plus the narrowest margin needed to remove it. The surgeon measures it at excision, before the specimen shrinks.

Here, the abdominal wall means the anterior and lateral wall and its overlying tissue. Intra-abdominal organs, the retroperitoneum and the peritoneal cavity fall outside it. A lipoma in the subcutaneous fat is the classic 22902 case. Once a mass extends through the fascia into muscle, it belongs in the subfascial series (22900 or 22901).

Tumor type changes the diagnosis code, not the procedure code. Lipomas, fibromas and malignant soft tissue tumors all report as 22902 when the layer and size fit. When the surgeon performs a radical resection, usually for a sarcoma, the code becomes 22904 or 22905 instead.

Which layer and size make it 22902?

The 22900 family splits on layer first and size second. Get either one wrong and the claim comes back denied or downcoded.

Decision point 1, layer: Does the operative note confirm the fascia stayed intact? If it does, you’re choosing between 22902 and 22903. If the fascia was opened, or the tumor extended below it, use the subfascial codes (22900 or 22901).

Decision point 2, size: Now apply that layer’s cutoff to the tumor plus its margin. A lipoma that measures 2.8 cm with its margin is 22902. At 3.1 cm, the same lesion is 22903.

Watch the subfascial cutoff, though. It sits at 5 cm, not 3 cm, and coders who assume one breakpoint for both series get caught out. The diagram below maps all six codes in the family.

What should the operative note say?

The operative note is what proves 22902. Imaging can’t show where the subcutaneous layer ends and the fascia begins, so the payer relies on what the surgeon wrote.

A defensible note for 22902 records six details:

• Location: The region of the abdominal wall, such as right lower quadrant, periumbilical or left flank.
• Tissue layer: A clear statement that dissection stayed subcutaneous and the fascia was not violated.
• Size with margin: The tumor’s greatest diameter plus the excision margin, measured by the surgeon at excision. Preoperative imaging and the pathology specimen don’t count.
• Margins: Whether a margin of normal tissue was taken, and how wide it was.
• Closure: Simple, intermediate or complex repair, plus any drain placed.
• Pathology: Confirmation that the specimen went to pathology, which supports the diagnosis code.

Simple and intermediate repairs are included in 22902. A complex repair can be reported separately, but only when the note documents it.

Watch for phrases like “subfascial extension” or “fascia was incised.” They shift the code to 22900 (subfascial, less than 5 cm) or 22901 (subfascial, 5 cm or greater). Billing 22902 in that case is a miscode, whatever the surgeon meant.

Which ICD-10 codes pair with 22902?

Lipoma is the most common reason for a 22902 claim. The diagnosis code drives medical necessity review and prior authorization, so pair it with care.

For D17.1 and D21.4, most commercial payers accept medical necessity when the note records pain, growth or functional limitation. A malignant diagnosis like C49.4 usually triggers prior authorization. The payer may also want oncology notes first.

If pathology points to a different site, our ICD-10 lookups for coders list every D17 and C49 code.

Which modifiers change a 22902 claim?

Modifiers tell the payer how the procedure was performed. A missing or wrong one is a frequent reason a 22902 claim gets adjusted.

What does 22902 pay in 2026?

In 2026, CPT code 22902 carries 15.49 total RVUs in a non-facility setting and 9.92 in a facility. At the 2026 conversion factor of $33.4009, that’s about $517 in the office and $331 in a hospital outpatient department or ASC, before GPCI.

Facility rates run lower because the facility bills its own overhead separately. Rates reset every January 1, so check the CMS Physician Fee Schedule lookup before you budget. The FastRVU lookup tool shows the same components with a geographic adjustment.

Commercial rates vary widely by contract and region. Surgical practice claims software that tracks allowed amounts by payer makes 22902 underpayments easier to spot when you post remittances.

Does 22902 need prior authorization?

It depends on the payer and the plan year, so check at the plan level before you schedule. That habit sits at the heart of medical billing compliance.

Traditional Medicare: Generally no prior authorization for 22902. Your Medicare Administrative Contractor’s Local Coverage Determinations (LCDs) may still set documentation rules, so review them before billing.

Medicare Advantage: These plans set their own rules, and some require prior authorization for 22902. Treat each plan like a commercial payer.

Commercial insurers: Many require authorization for soft tissue tumor excision, especially for a lipoma (D17.1) without documented symptoms. Expect to send:

• Clinical notes documenting symptoms, such as pain, functional limitation or rapid growth
• The measured tumor size from imaging or physical exam
• The physician’s attestation of medical necessity
• The ICD-10 code, with pathology or imaging that supports it
• For a malignant diagnosis (C49.4), oncology or surgical consultation notes

Asymptomatic lipoma removal is the request payers refuse most often. Put symptoms, functional impact or growth rate in writing, even when the indication seems obvious to the surgeon.

How does a 22902 claim move?

Here’s the path a typical 22902 claim takes, from booking to payment. Each step is part of the wider revenue cycle, and each one can stall the claim.

1. Schedule: Book the excision and capture the patient’s insurance details.
2. Check eligibility and prior auth: Confirm coverage, and get any authorization number before the surgery date.
3. Operative note: The surgeon records the layer, the tumor size plus margin, and the closure.
4. Code and pair: The coder assigns 22902 and pairs the ICD-10 code once pathology returns.
5. Submit: The claim goes out on a CMS-1500 through a clearinghouse.
6. Post the ERA: Match the electronic remittance advice against your contracted rate.
7. Rework denials: Correct the code or the documentation and resubmit within the payer’s appeal window.

What trips up a 22902 claim?

Denials on 22902 cluster around six causes. Each one has a fix you can build into denial management.

A clean claim process catches most of these before submission. The AAPC code range page lists every code in the 22900 family if you need to confirm a neighbor.

Check these six items before you submit

Run this list on every 22902 claim before it leaves the practice:

• The operative note says the fascia was intact.
• Size is recorded as tumor plus margin, measured at excision.
• The ICD-10 code matches the pathology report.
• Any required prior authorization number is on the claim.
• No separate line for a simple or intermediate repair.
• Follow-up visits within 90 days are flagged as global care.

What does the 90-day global cover?

CPT code 22902 carries a 90-day global surgical package under CMS policy. Routine care tied to the excision is paid within the procedure, including wound checks, suture removal and minor complications that don’t need the operating room.

You can still bill separately in these cases:

• Modifier 24: An E/M visit for a problem unrelated to the excision.
• Modifier 25: A significant, separately identifiable E/M service on the same day as a procedure or global visit.
• Modifier 58: A staged procedure planned at the time of the original surgery.
• Modifier 78: A return to the operating room for a complication.
• Modifier 79: An unrelated surgery during the global period.

Postoperative wound checks billed as E/M visits are a frequent finding in surgical superbill audits. The payer denies them as global care. If the visit only addressed the wound, it’s already paid.

How Pabau keeps 22902 claims moving

Many surgical practices still re-key codes from the operative note into a separate billing tool. They then chase remittances by hand, so a wrong layer or a missing authorization surfaces weeks later.

Pabau, the practice management and billing platform we build, pre-fills the CMS-1500 from the patient record. The CPT code on the service lands on the claim line, and required fields like authorization numbers are checked before you send.

For US practices, Pabau submits claims through the Claim.MD clearinghouse to thousands of US payers. You get eligibility checks before surgery, claim status updates from the payer, and electronic remittance advice (ERA) posting.

Conclusion

CPT code 22902 pays on two lines of the operative note, the layer and the size. So fix the dictation template before you chase another denial.

When surgeons record fascia status and tumor-plus-margin size every time, coders stop guessing and payers stop downcoding. It costs about a minute of extra dictation per case, far less than one appeal.
