What 64786 covers
This code describes surgery to remove a neuroma involving the sciatic nerve. A neuroma may develop after nerve injury or a prior operation and cause persistent pain or sensitivity. The procedure is typically performed by a peripheral nerve, neurosurgical, or orthopedic surgeon in an operating-room setting, with exposure of the sciatic nerve and excision of the lesion. The code is specific to the sciatic nerve; the operative report should identify the nerve and describe the lesion removed.
Select this code when the operative service is excision of a sciatic nerve neuroma, rather than excision of a neuroma on another nerve or removal of a different nerve lesion. Documentation should support the diagnosis, sciatic nerve involvement, and work performed. Medicare assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 reports bilateral surgery and is paid at 150%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.
