CPT® Code 64902

Add-On Code

The CPT® Code 64902 refers to the procedure of performing a nerve graft for each additional nerve using multiple strands, also known as a cable graft. This code is specifically utilized when there is a need to repair additional nerves following the primary nerve repair, which is reported separately. The process begins with the exposure of the injured nerve, where the extent of the nerve damage is carefully evaluated. If necessary, any damaged tissue is debrided to prepare the site for grafting. To assess nerve function, nerve testing and monitoring may be conducted, which are reported separately. The procedure involves meticulous dissection of the healthy proximal and distal segments of the nerve, ensuring that they are free from surrounding tissue. The length of the nerve graft is then determined based on the specific requirements of the repair. Harvesting the nerve graft involves exposing the donor nerve and dissecting it to the desired length, after which it is divided proximally and distally. The graft is then sutured end-to-end to the severed ends of the injured nerve, utilizing either single or multiple strands as indicated. Finally, the overlying soft tissues and skin are repaired in layers to complete the procedure. It is important to note that CPT® Code 64901 should be used for each additional nerve repaired with a single strand graft, while CPT® Code 64902 is designated for those repaired with a multiple strand graft.
