CPT® Code 64832

Add-On Code

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

The procedure described by CPT® Code 64832 involves the surgical suture of a digital nerve in the hand or foot, specifically addressing each additional digital nerve beyond the primary one. This procedure is typically indicated when a digital nerve has been severed, necessitating repair to restore function and sensation. The repair process, often referred to as end-to-end closure, can be performed using various surgical techniques, with epineural closure being the most common method employed. During this procedure, the two ends of the transected nerve are carefully exposed, allowing for direct access to the nerve fibers. Surgeons place multiple sutures in the epineurium, which is the outermost layer of the nerve, ensuring that the nerve ends are brought together without tension. This meticulous approach is crucial for promoting optimal healing and recovery of nerve function. It is important to note that CPT® Code 64832 should be used in conjunction with CPT® Code 64831, which is designated for the suture repair of a single digital nerve in the hand or foot, thereby allowing for accurate coding and billing of multiple nerve repairs performed during the same surgical session.
