CPT code 24076: Excision of subfascial soft tissue tumor, upper arm or elbow

Key takeaways

CPT code 24076 covers excision of a subfascial soft tissue tumor of the upper arm or elbow area, measuring less than 5 cm.

Depth comes from the operative note and size comes from the pathology report, and both must be in the record before the claim goes out.

A subfascial tumor of 5 cm or greater moves to CPT code 24073, not 24077, which covers radical resection instead.

CMS assigns 24076 a total of 15.6 RVUs, and the practice expense RVU is the same in facility and non-facility settings.

Practice management software like Pabau flags NCCI conflicts at entry and attaches documentation checklists, so fewer claims come back denied.

CPT code 24076 covers the excision of a subfascial soft tissue tumor measuring less than 5 cm, in the upper arm or elbow area. The official descriptor reads: Excision, tumor, soft tissue of upper arm or elbow area; subfascial, e.g., intramuscular; less than 5 cm.

Three qualifiers decide whether 24076 is the right choice: depth, size, and anatomic site. Each one has to appear in the record before the claim is submitted.

Descriptor terminology: What each qualifier means

Understanding the descriptor language protects against both upcoding and undercoding.

• Excision: complete surgical removal of the tumor and its margins, not a biopsy or a debulking procedure.
• Soft tissue: connective tissue structures such as fascia, muscle, and subcutaneous fat, rather than bone. If bone resection is involved, a different code applies.
• Upper arm or elbow area: the anatomic boundary covering the humerus shaft through the elbow joint. Forearm excisions fall under a separate code family.
• Subfascial (e.g., intramuscular): the tumor lies deep to the fascia, within or below the muscle layers. This is the depth qualifier that separates 24076 from the superficial code 24075.
• Less than 5 cm: the greatest tumor dimension recorded in the operative or pathology report. A subfascial tumor of 5 cm or greater moves to CPT code 24073.

One point catches coders out. Excision and radical resection are separate procedures with separate codes, so a larger tumor does not push 24076 into the 24077 range.

CPT 24075 vs 24076 vs 24073: Choosing the right code

The most common error in this family is picking a code from incomplete documentation of either depth or size. The table below covers the full excision and radical resection set for the upper arm and elbow. The same depth and size logic drives CPT code 21554 in the neck and thorax.

Depth is confirmed by the operative note, where the surgeon describes the dissection plane, and by the pathology report. Size is the greatest tumor dimension recorded at the time of excision. Both belong in the medical record before the claim is submitted.

Common modifiers for CPT code 24076

Modifiers change how a payer reads the code without changing the procedure itself. For CPT code 24076, four modifiers cover the majority of billing scenarios.

Modifier -22 carries the highest audit risk. Appending it without an operative note that explains the added complexity is an Office of Inspector General (OIG) red flag. Use it sparingly and document thoroughly.

Laterality is the quieter risk. The same -LT and -RT requirement applies across upper extremity surgery, including shoulder procedures such as CPT code 23462.

ICD-10 codes commonly paired with CPT code 24076

Medical necessity for CPT code 24076 rests on a diagnosis code that matches the pathology finding. Benign and malignant neoplasm codes are not interchangeable, so the ICD-10 you submit has to reflect the pathology report conclusion.

When a pairing is rejected, the remittance advice names the reason. Our guide to denial codes explains how to read those remark codes and what to correct before resubmitting.

Selecting C49.12 when pathology shows a benign tumor is a coding error that can trigger a medical necessity denial. In some cases it also invites a fraud audit. Reconcile the ICD-10 against the final pathology report before you submit.

Medicare reimbursement for CPT code 24076 (2026)

Medicare pays for CPT code 24076 by multiplying its Relative Value Units (RVUs) by the CMS conversion factor, then adjusting for geographic locality. The figures below are national values. Use the CMS Physician Fee Schedule lookup tool to find the locality-adjusted rate for your practice.

RVU breakdown for CPT 24076

RVU values are revised annually. Confirm the current figures in the AAPC entry for 24076 or the CMS fee schedule before you quote rates.

Facility vs non-facility reimbursement

Many office-based procedures pay more in the non-facility setting, because the practice absorbs the overhead. CPT code 24076 is an exception worth knowing. CMS assigns it the same practice expense RVU in both settings, so the physician’s total RVU does not move with place of service.

That does not make the place-of-service code optional. It still determines whether the hospital or ambulatory surgery center can bill its own facility claim alongside the surgeon’s Part B claim. Submitting the wrong one is a claim integrity issue CMS audits, so confirm it before submission.

NCCI bundling edits for CPT 24076

The National Correct Coding Initiative (NCCI) sets code-pair edits that CMS updates quarterly. Certain codes are bundled with CPT code 24076, so Medicare will not pay for both on the same claim unless specific conditions are met.

Pairs change with every update cycle, which is why medical billing compliance means rechecking the edit tables each quarter rather than once a year.

Key NCCI considerations for 24076:

• Bundled without modifier exception: routine closure codes, anesthesia add-ons, and basic surgical prep codes are bundled into the excision and cannot be billed separately.
• Bundled with modifier exception: modifier -59 may be required when 24076 is performed alongside an arthroscopic procedure at the same site and date. The operative note must confirm a separate site or a distinct clinical indication.
• Same-day injections: check the edit tables before reporting an injection such as CPT code 20550 on the date of the excision.
• Column 2 edits: evaluation and management codes billed on the same day as 24076 fall under global surgery package rules. Post-operative visits inside the 90-day global period are usually not separately billable.
• Verify quarterly: NCCI edits update every January, April, July, and October. Verify any code pair in the current CMS NCCI Policy Manual before billing.

Rehabilitation after the excision sits outside that global package. It is billed on its own claim by the physical therapy provider, under therapy codes rather than surgical ones.

Documentation requirements for CPT code 24076

Incomplete documentation drives more denials and post-payment audits on soft tissue excision codes than any other factor. Payers and CMS auditors expect the elements below in the record for every claim billed under CPT code 24076.

Using digital intake and operative forms that prompt for each element reduces the chance of missing information at the point of care. Well-structured digital medical forms standardize that capture across the practice.

• Operative note, tumor depth: state plainly that the tumor was subfascial or intramuscular. Phrases such as “deep to fascia” or “within the muscle belly” are enough. Without depth documentation, an auditor defaults the claim to 24075.
• Tumor size measurement: the greatest dimension in centimeters must appear in the operative note or the pathology report. If the two measurements differ, record both and explain the discrepancy.
• Pathology report: needed to confirm whether the tissue is benign or malignant and to support the ICD-10 on the claim. A pre-authorization pairing using M79.821 must be updated to the final diagnosis.
• Anatomic site: document laterality and the specific location within the upper arm or elbow region. This supports modifier -LT or -RT and satisfies Medicare’s laterality requirement.
• Surgical approach: describe the incision type, the planes dissected, and the closure technique. This is what supports a modifier -22 claim for increased complexity.
• Pre-operative diagnosis and indication: the patient’s symptom history establishes medical necessity. Pain, functional limitation, and the rate of mass growth all belong in the note.

Common billing errors and how to avoid them

These are the four mistakes auditors flag most often on CPT code 24076 claims, drawn from AMA coding resources and NCCI compliance patterns.

• Billing 24073 without a documented size: 24073 is the subfascial code for tumors of 5 cm or greater. Reporting it when the operative note gives no measurement is a familiar OIG audit trigger. Default to 24076 and correct the claim once pathology confirms the size.
• Reaching for 24077 on a large tumor: 24077 is a radical resection code, not the next size up from 24076. Size alone never moves an excision into the radical resection range. The operative note has to describe a radical resection.
• Using 24076 for superficial tumors: if the note describes a subcutaneous mass above the fascia, 24075 or 24071 applies instead. Billing 24076 there is upcoding by depth rather than by size.
• Missing the laterality modifier: Medicare requires -LT or -RT on upper extremity codes. Claims without laterality often suspend for manual review, which adds weeks to the payment timeline.

Each of these is caught by the same habit: reading the operative note against the descriptor before the claim goes out. That check is also what turns a first submission into a clean claim.

How practice management software supports CPT code 24076 billing

Orthopedic and sports medicine practices billing this code hit the same three friction points. Bundling conflicts surface late, and operative notes reach the biller with an element missing. Place-of-service coding is left to whoever happens to be on the claim that day.

Practice management software like Pabau moves those checks upstream. Codes are validated against the NCCI edit tables at entry. A conflict with 24076 shows up as a flag before submission, not as a denial 30 days later. Our claims management software handles that validation step.

Documentation templates can be built to prompt for tumor depth, size, laterality, and approach as the surgeon closes the note. Connecting those notes to billing through EHR integration removes the manual transcription step where detail usually goes missing.

The result is a shorter feedback loop. Errors are caught on the day of the procedure, by the person who can still fix them. Nobody is left reconstructing an incomplete note a month later.

Conclusion

Most 24076 problems are not coding problems. They are documentation problems that surface at the coding stage, once the operative note is finished and the surgeon has moved on.

So the useful work happens earlier. Fix the note template so depth, size, and laterality cannot be left blank, and most of this article stops being relevant to your practice. Keep the size threshold straight while you are at it: 5 cm or greater means 24073, and 24077 is a different operation altogether.

The trade-off is a few extra seconds at the end of each case, against the weeks a suspended claim costs. Book a demo to see how Pabau validates surgical codes and captures operative documentation before the claim goes out.
