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

What 27447 covers

An orthopedic surgeon exposes the knee, removes damaged cartilage and bone from the distal femur and proximal tibia, balances the ligaments, and places femoral and tibial components with a polyethylene insert. The components may be cemented or press-fit, and the patella may also be resurfaced. Typical indications include advanced osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis after conservative treatment has failed. Surgery is generally performed in a hospital or ambulatory surgery center.

Report one service per knee when both medial and lateral tibiofemoral compartments are replaced. The operative note should identify the compartments treated, implants placed, and whether the patella was resurfaced. Osteophyte removal, soft tissue balancing, and synovial work performed as part of the replacement are included. The 90-day global period includes the preoperative visit the day before surgery and related postoperative care. For bilateral same-session replacement, report modifier 50; Medicare pays 150%. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and additional procedures at 50%. An assistant at surgery may be paid; co-surgeons require supporting documentation. Team surgery is not permitted.
