CPT® Code 24345

The procedure described by CPT® Code 24345 involves the surgical repair of the medial collateral ligament (MCL) of the elbow using local tissue. The MCL, also known as the ulnar collateral ligament, is a critical structure that stabilizes the elbow joint and is composed of three interconnected bands of tissue. These bands include the anterior band, which connects the anterior medial epicondyle of the humerus to the coronoid process of the ulna; the posterior band, which attaches to the posterior aspect of the medial humeral epicondyle and the medial edge of the ulnar olecranon process; and an intermediate band that merges with both the anterior and posterior bands. Injuries to the MCL can occur due to acute trauma, such as a fall or direct impact, or from chronic stress, often seen in athletes who perform repetitive overhead motions. The surgical repair procedure involves making an incision over the medial aspect of the elbow to access the joint capsule, followed by careful dissection to expose the MCL. The damaged ligament is then debrided, and local tissue is utilized to reinforce the repair, ensuring the stability and functionality of the elbow joint post-surgery.
