Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 28735 covers

This code covers fusion of multiple joints in the midfoot, or a transverse fusion across the midfoot, when the operation also includes an osteotomy. Foot and ankle orthopedic surgeons and podiatric surgeons may perform it for conditions such as painful midfoot arthritis or deformity requiring both joint fusion and bony realignment. The operative report should identify the joints fused and describe the osteotomy and its role in the correction.

Select this code when the fusion involves multiple or transverse midtarsal or tarsometatarsal joints and an osteotomy is performed; a single-joint fusion or a multiple-joint fusion without osteotomy points to a different code. The osteotomy is part of the service represented here. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
