What 28805 covers
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.
