Orthopedic surgery
Reports surgical fusion of the hip joint combined with an osteotomy below the trochanter to position the femur during the fusion procedure.
An orthopedic surgeon uses this code for hip joint arthrodesis performed together with a subtrochanteric osteotomy, an intentional cut in the femur below the trochanter. The osteotomy allows the surgeon to adjust femoral position as part of creating a stable fused hip. This is a salvage operation for selected patients in whom eliminating hip motion is the treatment plan; it is not a code for an isolated femoral osteotomy or a hip replacement.
Select the code when the operative report supports both hip fusion and the subtrochanteric osteotomy. Document the treated side, the fusion procedure, and the osteotomy and its role in the operation. 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 one 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%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
