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

What 21188 covers

This major reconstructive operation addresses the bony framework of the midface, such as the maxillary and cheek-region structures. It may be performed for a congenital craniofacial deformity, significant facial trauma, or a defect after removal of diseased tissue. Craniofacial, oral and maxillofacial, and plastic surgeons commonly perform this work in an operating room. The operative report should identify the reconstructed anatomy and describe the surgical approach and any grafting or other reconstruction performed.

Report 21188 when the documented midface reconstruction matches this procedure rather than a separately defined LeFort reconstruction or a lower-jaw procedure. The 90-day global period includes 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. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be allowed; co-surgeons and team surgery are not permitted.
