Question: Washington Subscriber Answer: Both of your physicians could be right depending on the situation. Check with the payer before submitting your claim following one of these options: • Report 27125 (Hemiarthroplasty, hip, partial [e.g., femoral stem prosthesis, bipolar arthroplasty]) if the orthopedic surgeon resurfaces only the acetabular or femoral head. • Report 27130 (Arthroplasty, acetabular and proximal femoral prosthetic replacement [total hip arthroplasty], with or without autograft or allograft) if the surgeon resurfaced both the acetabulum and femoral head. • Use S2118 (Metal-on-metal total hip resurfacing, including acetabular and femoral components) for hip resurfacing instead of the CPT codes for some private payers such as Blue Cross/Blue Shield.
