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

What 21175 covers

This major craniofacial operation reshapes and advances the frontal bone and supraorbital rims to reconstruct the lower forehead and brow region. It is commonly performed for craniosynostosis-related deformity by a craniofacial or plastic surgeon, often working with a neurosurgeon, in a hospital operating room. Bone grafting, when performed as part of the reconstruction, is included in the service.

Report the code when the operative work includes the bifrontal forehead and supraorbital rim reconstruction, rather than a more limited superolateral orbital rim procedure or forehead reconstruction alone. The operative report should identify the anatomy reconstructed, advancement performed, and any grafting. The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
