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

What 27664 covers

This code covers primary operative repair of an extensor tendon in the leg without a graft. A typical example is repair of a disrupted tibialis anterior tendon. Orthopedic and foot-and-ankle surgeons commonly perform the service in an operating room or other surgical setting. The code is specific to extensor tendons in the leg; Achilles tendon repairs and flexor tendon repairs have separate codes.

Report it for each tendon repaired, and document the tendon, the primary nature of the repair, and that no graft was used. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate; the descriptor is reported for each tendon. Assistant-at-surgery payment requires documented medical necessity. Co-surgeons and team surgery are not permitted.

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
