CPT® Code 64896

The procedure described by CPT® Code 64896 involves the surgical repair of a nerve in the hand or foot using a multiple strand nerve graft. This technique is employed when a nerve has been injured and requires reconstruction to restore function. The use of a multiple strand graft allows for a tension-free repair, which is crucial for optimal healing and recovery. During the procedure, the injured nerve is carefully exposed, and the extent of the injury is assessed. Any damaged tissue is debrided to prepare the site for grafting. Additionally, nerve testing and monitoring may be performed to evaluate the function of the nerve, ensuring that the repair is necessary and appropriate. The healthy segments of the nerve, both proximal and distal to the injury, are meticulously dissected from surrounding tissues, and the length of the graft needed is determined. The graft itself is harvested from a donor nerve, which is also exposed and dissected free from surrounding tissue to obtain the required length. Once the graft is prepared, multiple strands of the donor nerve are sutured end-to-end to the severed ends of the injured nerve. Finally, the overlying soft tissues and skin are repaired in layers to complete the procedure. It is important to note that this code is specifically used when the length of the nerve graft exceeds 4 cm; for grafts that are 4 cm or less, CPT® Code 64895 should be utilized instead.
