Foot surgery

About 28805: Transmetatarsal foot amputation

A transmetatarsal foot amputation removes the forefoot through the metatarsals and is reported when disease or injury requires removal at that level.

This operation removes the forefoot by dividing the metatarsals, typically to address severe infection, gangrene, or nonviable tissue that cannot be managed with a toe or single-ray amputation. An orthopedic or podiatric surgeon commonly performs it in a hospital or other surgical setting. The operative level distinguishes this procedure from removal limited to one toe or ray and from a more proximal midfoot amputation.

Select the code from the documented extent of the operation, not the diagnosis alone. The operative report should identify the side, the metatarsal-level transection, and the tissue removed. 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 procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; CMS does not permit co-surgeon or team-surgery billing for this procedure.
