What 64840 covers
This service covers operative repair of a major peripheral nerve in the leg, such as repair after a traumatic laceration or transection. It is typically performed by a surgeon with peripheral nerve, orthopedic, plastic, or neurosurgical expertise in an operating room. The operative report should identify the injured nerve and leg location, describe the injury and repair performed, and distinguish the service from treatment of a smaller nerve in the hand or foot or repair of the sciatic nerve.
Report the code supported by the nerve treated and the operative service; document the findings and repair technique. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
