What 28113 covers
This service removes the head of a third, fourth, or fifth metatarsal. Foot and ankle surgeons and podiatrists may perform it for a painful prominence, deformity, or pressure problem such as a recurrent ulcer beneath the affected metatarsal head. The operative report should identify the bone and side, describe the extent of bone removed, and explain the clinical indication. A procedure that reshapes the bone without removing the head is a different service.
Report this code when the documented work is complete excision of one of these metatarsal heads, rather than partial removal of the fifth metatarsal head or excision of a different metatarsal. It has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral surgery, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
