What 28120 covers
An orthopedic or foot and ankle surgeon removes a portion of the talus or calcaneus. The work may involve shaping or scooping out bone, removing a sequestrum, or excising a segment. Typical clinical reasons include osteomyelitis or a localized bone lesion. The service is generally performed in an operating room, with the operative report identifying the affected bone and the extent of removal.
Choose this code when the documented procedure is a partial excision of the talus or calcaneus, rather than a biopsy alone or removal of a different foot bone. The operative note should support the bone treated, the indication, and the partial excision performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
