CPT code 64792: Neuroma excision, cranial nerve2026 Medicare rate & RVUs

Medicare pays $1,213.12 for 64792 nationally in a facility.

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

What 64792 covers

This service involves surgically exposing and removing a neuroma arising from a cranial nerve. It is typically performed by a neurosurgeon or an otolaryngologist or head-and-neck surgeon when a focal nerve lesion is the operative target. The code is distinguished by the cranial nerve location; a neuroma involving a peripheral nerve of an extremity or a sympathetic nerve belongs to a different anatomic category. Cases are generally performed in a hospital operating room rather than an office setting.

Report the service when the operative record supports removal of a cranial nerve neuroma, identifying the nerve, lesion, and work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during the following 90 days. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
