CPT® Code 26390

The procedure described by CPT® Code 26390 involves the excision of a flexor tendon in the hand or finger, accompanied by the implantation of a synthetic rod. This procedure is typically indicated when a flexor tendon repair has either failed or has not been performed in a timely manner, necessitating a delayed flexor 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 injured tendon to be meticulously dissected free from the surrounding tissue and subsequently excised. 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 scaffold for the healing process, remaining in place for approximately 10 weeks while the tendon sheath heals around it. After this healing period, the second stage of the procedure, which involves the actual tendon grafting, can be performed under a different CPT® code. The careful execution of this procedure is crucial for restoring function and mobility to the affected hand or finger.
