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

What 27425 covers

The surgeon exposes and releases tight tissue along the outside of the kneecap through an open approach, reducing excessive lateral pull or restraint. Orthopedic surgeons commonly perform the procedure for patellar tilt or maltracking associated with a tight lateral retinaculum, often in a hospital operating room. The operative report should establish the indication and describe the open exposure and release performed.

Report 27425 when the documented service is an open lateral retinacular release; an arthroscopic release is represented by a different code. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. For bilateral release reported with modifier 50, Medicare pays 150%. Medicare does not pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
