CPT® Code 23120

A partial claviculectomy, designated by CPT® Code 23120, involves the surgical removal of a portion of the clavicle, which is the bone connecting the arm to the body. This procedure is typically performed through an open surgical approach, allowing the surgeon to access the clavicle directly. The indications for this surgery can include various conditions such as tumors, infections, or vascular issues that compromise the integrity of the clavicle. One specific type of partial claviculectomy is the Mumford procedure, which is aimed at alleviating pain and restoring motion in patients suffering from arthritis or impingement at the acromioclavicular joint. During the procedure, a skin incision is made over the area of the clavicle that requires excision. The surgeon carefully dissects the surrounding soft tissues to expose the clavicle and identifies the specific portion that needs to be removed. A surgical burr is then utilized to divide the clavicle, allowing for the excision of the affected segment. If the Mumford procedure is indicated, the anterior aspect of the acromion is also resected to eliminate the articular surface, followed by smoothing the underside of the acromion with an end-cutting shaver. The distal end of the clavicle is then exposed and resected, typically removing about 1 to 2 cm to ensure that the articular surfaces of the acromion and clavicle do not come into contact, thereby reducing pain and improving function.
