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

What 27665 covers

This code describes secondary repair of an extensor tendon in the lower leg, performed without a graft or with graft material when needed. It may be used for delayed or previously treated tendon injuries when the surgeon repairs an extensor tendon such as the tibialis anterior or a toe extensor. Orthopedic surgeons and foot and ankle surgeons typically perform the procedure in an operating room, often for chronic tendon disruption or a failed prior repair.

Report one unit for each tendon repaired, and document the specific tendon, the injury or prior repair, the secondary nature of the procedure, and whether graft material was used. Code 27664 is the primary-repair counterpart; code 27665 is not the code for a primary repair. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
