What 28080 covers

This service removes a segment of an irritated, thickened interdigital nerve, commonly for a Morton's neuroma causing forefoot burning or a pebble-like sensation. Podiatrists and foot and ankle surgeons typically perform it in an operating room or ambulatory surgery setting. The third web space is a common site, but code selection follows the procedure performed, not a presumed location.

Report one unit for each neuroma excised, with documentation identifying the side, interspace, symptoms, and removal of the nerve segment. The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. When other procedures occur in the same session, the highest-valued procedure is paid in full and the others are subject to a 50% multiple-procedure reduction. Modifier 50 is inappropriate. An assistant is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

28080 billing questions

How is this different from an injection for Morton's neuroma?

Use 28080 when the surgeon excises the affected interdigital nerve segment. Code 64455 describes an injection treatment, not surgical removal.

Does this code cover removal of any forefoot mass?

No. It is specific to excision of an interdigital neuroma. Soft-tissue tumor codes such as 28039 or 28043 are selected according to tumor depth and size when those criteria describe the procedure.

Can modifier 50 be used when both feet are treated?

No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard 50% multiple-procedure reduction.

When can an assistant surgeon be paid?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
