CPT® Code 64907

A nerve pedicle transfer is a surgical procedure that involves the transfer of a nerve along with a muscle pedicle, which includes the motor endplate of the nerve. This procedure is typically performed in two stages. In the first stage, represented by CPT® Code 64905, the surgeon develops and transfers the nerve pedicle to a designated donor site. The process begins with making an incision over the injured nerve, followed by the elevation of skin, fascial, or muscle flaps as necessary to expose the injured nerve and its branches. The incision may be extended, or a second incision may be created at the site where the nerve pedicle will be harvested. Utilizing microscopic visualization, the surgeon carefully dissects the donor nerve and its motor endplate from the surrounding tissues, along with the associated muscle tissue. A tunnel is then created from the donor site to the injured nerve, allowing the nerve pedicle to be pulled through this tunnel to the injury site. Once in position, the nerve pedicle is secured to the injury site with sutures. In the second stage, denoted by CPT® Code 64907, after the nerve axons have regenerated and normal nerve function has been restored, the nerve pedicle is severed at its original site. This staged approach allows for the restoration of nerve function while ensuring that the nerve pedicle is properly integrated into the surrounding tissues before final severance.
