What 28111 covers

The surgeon removes a limited portion of the head of the first metatarsal, the long bone behind the great toe. This may address a painful prominence or localized bone problem. The procedure is performed by a foot and ankle surgeon or other qualified surgeon, commonly in an operating room or ambulatory surgery center. The operative report should identify the first metatarsal and describe the portion removed and the reason for excision.

Select this code when the work is a partial resection of the first metatarsal head, rather than a resection of another metatarsal or removal of the whole bone. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued is paid in full and the others are subject to the standard multiple-procedure reduction. For bilateral surgery, modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons are paid only with supporting documentation, and team surgery is 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.

This code is for partial resection of the first metatarsal head. Code 28110 applies to the fifth metatarsal head.

When is 28112 more appropriate?

Use 28112 when the partial resection involves the second metatarsal head, rather than the first.

Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

How is bilateral surgery reported?

For bilateral procedures, report modifier 50; CMS pays the bilateral procedure at 150%.

What documentation supports reporting this code?

The operative report should establish that the surgeon removed part of the first metatarsal head and document the indication and extent of the resection.

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.
