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

What 27580 covers

Code 27580 describes an operation that fuses the knee joint, eliminating motion to provide a stable limb. Orthopedic surgeons may use it as a salvage procedure for a severely damaged or unstable knee, including some cases of infection or failed knee replacement when another reconstruction is not suitable. The procedure is generally performed in a hospital or other surgical facility.

Report the code when the surgeon performs knee arthrodesis, not for fracture fixation, manipulation of a stiff knee, or prosthesis removal alone. The operative report should support the fusion, the treated side, and the clinical reason for choosing arthrodesis. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
