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

What 21182 covers

This service rebuilds a cranial bone defect with multiple autografts, including harvesting the grafts. It is typically performed by a neurosurgeon or craniofacial plastic surgeon in an operating room for a patient who needs structural reconstruction after a defect or prior cranial surgery. The code represents the smallest defect-area tier in the 21182–21184 series; the operative record should support the defect’s total area and the use of multiple autografts.

Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction. An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this anatomy and descriptor.
