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

What 27301 covers

A surgeon opens the deep tissue planes of the thigh or knee region to evacuate a collection such as an abscess, infected bursa, or hematoma. Orthopedic surgeons commonly perform this service in an operating room, although the appropriate setting depends on the patient and the collection. The operative report should establish the site and depth and describe the collection and its drainage. A superficial skin abscess, a collection within bone, and a knee-joint procedure represent different services.

Report the code when the documented work is deep incision and drainage in the thigh or knee region, not excision of a mass or drainage limited to the skin. This major surgery code includes 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. Bilateral reporting with modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.
