What 64831 covers

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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
