CPT® Code 29824

The CPT® Code 29824 refers to a surgical procedure known as arthroscopy of the shoulder, specifically a distal claviculectomy, which is also commonly referred to as the Mumford procedure. This minimally invasive technique is performed to alleviate pain and improve function in patients suffering from shoulder conditions related to the acromioclavicular joint. During the procedure, the patient is typically positioned either in a lateral decubitus position, where the body is lying on its side with the arm suspended, or in a beach chair position, which allows for optimal access to the shoulder joint. The procedure begins with the application of skin traction to the arm to facilitate access to the joint. Incisions are made at the anterior and posterior portals of the shoulder joint, and sterile saline solution is introduced to expand the joint space, providing a clearer view for the surgeon. The initial step involves a diagnostic examination of the glenohumeral joint and the subacromial space using specialized arthroscopic instruments. If necessary, additional portal incisions are created to allow for the introduction of surgical tools to access the surgical site effectively. The procedure includes the resection of the anterior aspect of the acromion, which is performed using a stone-cutting burr to remove approximately 10 mm or one-half to two-thirds of the anterior acromion. This step is crucial for alleviating impingement symptoms. Following this, the distal end of the clavicle is exposed and resected, typically excising about 1-2 cm of the distal clavicle. This excision is essential to eliminate contact between the articular surfaces of the acromion and the clavicle, thereby reducing pain and improving shoulder mobility. Upon completion of the procedure, the instruments are removed, excess fluid is drained from the joint, the incisions are closed, and a dressing is applied to promote healing.
