CPT code 21150: Midface reconstruction, leFort II, without graft2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 21150 in California.

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

What 21150 covers

This service reconstructs the central midface by mobilizing and repositioning facial bones in a LeFort II pattern. It is performed by craniofacial, oral and maxillofacial, or plastic surgeons, generally in a hospital operating room. Clinical indications may include congenital midface deficiency or reconstruction after facial trauma. The code identifies the LeFort II level of reconstruction, rather than a LeFort I or LeFort III pattern.

Report 21150 when the documented reconstruction follows the LeFort II pattern and does not include bone grafting; use 21151 when a bone graft is part of the reconstruction. The operative report should establish the osteotomy pattern, reconstruction performed, and whether grafting was used. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Assistant-at-surgery services may be paid; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate for this code.
