2025 CPT code 64832

Suture of digital nerve, hand or foot; each additional digital nerve (List separately in addition to code for primary procedure)

This code should only be used when multiple digital nerves are repaired during the same operative session. The primary procedure code (64831) should be reported first, followed by 64832 for each additional nerve repair. Use modifier -F1 through -TA to specify the location of the nerve repair in the hand or foot on 64832

Modifiers may be applicable to this code. Refer to current CPT guidelines and payer policies for appropriate modifier usage.

Medical necessity for this code must be supported by documentation demonstrating the functional impairment caused by the nerve injury. The documentation should explain why surgical repair is necessary to restore function.

Following repair of an initial nerve in a finger or toe at the same session, the provider accesses another digital nerve through the open wound or incision. He identifies the injured structure and debrides the wound as needed. He then trims the damaged ends of the nerve as needed to expose the healthy tissue. He carries out the dissection using high-power magnification and takes care not to injure the surrounding structures. He then sutures the healthy nerve ends together without creating tension. If the damaged nerve has motor as well as sensory functions, he gathers a group of nerve fibers and sutures them together. He then closes the wound or incision.

In simple words: Repair of each additional damaged nerve in a finger or toe during the same procedure.

The provider repairs another nerve in a finger or toe after repair of an initial nerve repair at the same session. The procedure restores sensory and/or motor functions when the nerves become damaged or severed as a result of injury or trauma. Following repair of an initial nerve in a finger or toe at the same session, the provider accesses another digital nerve through the open wound or incision. He identifies the injured structure and debrides the wound as needed. He then trims the damaged ends of the nerve as needed to expose the healthy tissue. He carries out the dissection using high–power magnification and takes care not to injure the surrounding structures. He then sutures the healthy nerve ends together without creating tension. If the damaged nerve has motor as well as sensory functions, he gathers a group of nerve fibers and sutures them together. He then closes the wound or incision.

Example 1: A patient presents with lacerations to two fingers, severing nerves in both. During the same surgical session, the surgeon repairs both nerves. 64831 would be reported for the repair of the first nerve, and 64832 would be reported for the repair of the second nerve., A patient sustains a deep cut to their hand, damaging three separate digital nerves. The surgeon repairs all three nerves during the same procedure. 64831 is reported for the first nerve repair, and 64832 is reported twice, once for each of the two additional nerve repairs., A patient has a crushed toe, resulting in damage to two digital nerves. The surgeon repairs both nerves. 64831 is reported for the repair of the first nerve, and 64832 is reported for the repair of the second nerve.

Documentation should include the diagnosis, the specific nerves repaired, the operative technique used, and any complications encountered. It should also clearly indicate that the additional nerve repairs were performed during the same surgical session as the primary nerve repair.
