What 28043 covers

This code describes removing a soft-tissue tumor located in the subcutaneous layer of the foot or toe, with a size under 1.5 cm. The lesion lies beneath the skin but does not extend into deeper tissue such as fascia or muscle. Podiatric and orthopedic surgeons commonly perform this procedure for a localized mass in an office or surgical facility; the excised tissue may be sent for pathologic examination.

Select the code based on both the lesion’s size and its depth, not simply the incision length. The operative report should identify the foot or toe site, document the tumor’s size, and show that it was subcutaneous. This major surgery code has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; 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.

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.
