About 28302: Ankle bone realignment osteotomy
Reports surgical cutting and realignment of an ankle bone to correct deformity, with fixation when needed, during reconstructive foot-and-ankle surgery.
This service is a corrective cut through bone at the ankle, allowing the surgeon to change alignment for an angular deformity. Orthopedic foot-and-ankle surgeons and podiatrists perform it in an operating room; the bone may be stabilized with internal fixation as part of the osteotomy. It is distinct from cuts directed to the heel, other tarsal bones, or metatarsals.
Report 28302 for the ankle-site osteotomy, not simply for ankle exposure or fixation without the corrective bone cut. The operative report should identify the treated side and site, the deformity and correction, and whether fixation was used. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, 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 may be made; co-surgeons require supporting documentation, and team surgery is not permitted.
