CPT® Code 23440

The procedure described by CPT® Code 23440 involves the resection or transplantation of the long tendon of the biceps, specifically targeting the long head of the biceps brachii muscle. This muscle is crucial for various arm movements and has two points of attachment at the shoulder: the long head, which connects to the supraglenoid tubercle of the scapula, and the short head, which attaches to the coracoid process of the scapula. The resection or transplantation is typically indicated for patients suffering from a tear in the tendon or chronic tendonitis, conditions that can lead to pain and functional impairment in the shoulder. The surgical approach begins with an incision over the anterior shoulder, allowing access to the tendon. The procedure may involve detaching the long head of the biceps from its attachment point if it is severely damaged, which may result in the biceps being anchored solely by the short head. Alternatively, if feasible, the long head may be transplanted to a different location within the shoulder joint. The surgery also includes the debridement of damaged tissue and the preparation of the transplant site, ensuring that the tendon can be securely reattached using various fixation methods. This comprehensive approach aims to restore function and alleviate pain associated with biceps tendon injuries.
