What 64886 covers
This operation bridges a nerve gap in the head or neck with a graft when the nerve ends cannot be joined directly without tension. A common setting is facial nerve reconstruction after nerve injury or removal during head-and-neck surgery. Otolaryngology, plastic and reconstructive, and neurosurgical specialists may perform the procedure in an operating room, often using microsurgical techniques to connect the graft to the nerve ends.
Select this code when the graft length is greater than four centimeters; document the reconstructed nerve, graft length, and operative work. The service has a 90-day global period, including 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 is inappropriate for this code. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
