CPT® Code 23415

The procedure described by CPT® Code 23415 involves the release of the coracoacromial ligament, which is a critical structure in the shoulder joint. This ligament connects the coracoid process, located on the anterior aspect of the scapula, to the acromion process on the posterior scapula, playing a vital role in stabilizing the shoulder joint. The procedure typically begins with a skin incision made on the superior aspect of the shoulder, directly over the coracoacromial ligament. Following the incision, the surgeon dissects through the soft tissues to expose the ligament. Once exposed, the shoulder joint is thoroughly explored to confirm any impingement of the rotator cuff against the edge of the acromion, which is often associated with the attachment of the coracoacromial ligament. If impingement is confirmed, the ligament is released by detaching it from the undersurface of the acromion. Additionally, the ligament may be debrided using a shaver to remove any degenerated tissue. The undersurface of the acromion is then inspected to assess whether an acromioplasty is necessary. If acromioplasty is indicated, the surgeon will smooth the undersurface of the acromion using an end-cutting motorized shaver. A burr may also be utilized to eliminate any remaining ligament fibers and to clearly define the anterolateral surface of the acromion. Finally, the surgical site is irrigated with sterile saline, and the incisions are meticulously closed in layers to promote optimal healing.
