What 64772 covers
This operation intentionally interrupts a spinal nerve outside the dura, by severing or avulsing it. A neurosurgeon or spine surgeon typically performs it in an operating room when the treatment plan calls for surgical interruption of a specific spinal nerve. The operative report should identify the nerve, its extradural location, and the procedure performed.
Report this code for one spinal nerve; documentation should distinguish the target from a cranial or peripheral nerve. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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 multiple-procedure reduction. Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.
