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

What 27598 covers

At knee-disarticulation surgery, the surgeon separates the lower leg through the knee joint, leaving the femur intact. Orthopedic, vascular, or trauma surgeons may perform this operation for nonviable tissue from severe limb ischemia or infection, or for devastating injury, generally in an operating room. The operative report should establish the amputation level; a cut through the tibia below the knee or through the femur above the knee is a different level.

Report the service for the through-knee procedure and document the indication, operative level, and side. CMS assigns a 90-day global period, including 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 the others at 50%. For bilateral surgery, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
