CPT® Code 26415

The procedure described by CPT® Code 26415 involves the excision of an extensor tendon in the hand or finger, accompanied by the implantation of a synthetic rod. This procedure is typically indicated when an extensor tendon repair has either failed or has not been performed in a timely manner, necessitating a delayed tendon grafting approach. The process is executed in two stages, with the first stage being the focus of this code. During this initial stage, a zigzag incision is made over the affected tendon to access the injured area. Careful dissection of the surrounding soft tissues is performed to protect vital neurovascular structures. The tendon sheath is then incised, allowing for the dissection and excision of the injured tendon. Following the removal of the damaged tendon, a synthetic rod is inserted along the entire length of the tendon sheath. This rod serves as a temporary support structure while the tendon sheath heals around it. After the synthetic rod is placed, the overlying soft tissues and skin are meticulously closed in layers. The synthetic rod is designed to remain in place for approximately 10 weeks, during which time the healing process occurs, preparing the site for the subsequent tendon grafting procedure, which is addressed under CPT® Code 26416.
