What 28730 covers
The surgeon prepares the involved midfoot joint surfaces and stabilizes them so the bones can unite. This code covers fusion involving multiple midtarsal or tarsometatarsal joints, or a transverse fusion across the midfoot. Orthopedic foot and ankle surgeons and podiatrists commonly perform these procedures in an operating room for conditions such as painful midfoot arthritis or instability.
Select this code when the operative report supports a multiple-joint or transverse fusion without the osteotomy distinction associated with 28735. Document the fused joints, side, indication, and any osteotomy performed. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. With modifier 50, a bilateral procedure is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.
