Peripheral nerve surgery
About 64831: Digital nerve suture repair
Reports surgical suture repair of a digital nerve in a hand or foot, commonly after traumatic transection or laceration.
A surgeon repairs a cut or transected digital nerve in a finger, thumb, or toe by bringing the nerve ends together and suturing them. This procedure is commonly performed by a hand or orthopedic surgeon, plastic surgeon, or another surgeon experienced in peripheral nerve repair, often in an operating room after a sharp laceration or other injury. The operative record should identify the injured digital nerve and document the repair performed.
Report 64831 for a digital nerve repair in the hand or foot; distinguish it from repair of a non-digital nerve in the hand or foot. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For bilateral procedures, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.
