What 28110 covers

This procedure removes part of the fifth metatarsal head, commonly for a painful bunionette (tailor’s bunion) with lateral prominence and shoe-related pressure or irritation. A podiatrist or orthopedic foot-and-ankle surgeon typically performs it in an operating room or ambulatory surgery center. The operative work is a partial resection of the fifth metatarsal head, rather than removal of the entire metatarsal or correction by metatarsal osteotomy.

Select the code when the documented operation removes only part of the fifth metatarsal head. The operative report should identify the bone and side, describe the extent of resection, and support the indication. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is statutorily restricted; co-surgeons require 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.

28110 billing questions

When is this code appropriate for a bunionette?

Use it when the surgeon partially removes the fifth metatarsal head. A bunionette diagnosis alone does not establish the procedure; the operative report must support the partial resection.

How does it differ from complete fifth metatarsal head removal?

This code represents partial removal of the fifth metatarsal head. Code 28115 is for complete excision of that head.

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.
