CPT® Code 64831

The procedure described by CPT® Code 64831 involves the surgical suture of a severed digital nerve in either the hand or foot. This type of nerve repair is critical for restoring sensation and function to the affected digit. The term "digital nerve" refers to the nerves that provide sensory innervation to the fingers and toes. When these nerves are severed, it can lead to loss of feeling and impaired motor function in the corresponding digit. The repair process, commonly known as end-to-end closure, is typically performed using a technique called epineural closure. In this method, the two ends of the transected nerve are carefully exposed, allowing for direct visualization. Surgeons then place several sutures in the epineurium, which is the outer layer of the nerve, ensuring that the nerve ends are brought together without tension. This careful approximation is essential for promoting optimal healing and restoring nerve function. For the repair of a single digital nerve, the appropriate code to use is 64831. If additional digital nerves require suturing, CPT® Code 64832 should be utilized for each subsequent nerve repair.
