CPT® Code 23107

The procedure described by CPT® Code 23107 refers to an arthrotomy of the glenohumeral joint, which is the primary joint of the shoulder. This surgical intervention involves an open exploration of the joint to assess and address various conditions that may affect its function. The glenohumeral joint is characterized as a shallow ball-and-socket joint, formed by the articulation of the glenoid fossa of the scapula and the head of the humerus. The purpose of this procedure is to investigate the joint for the presence of disease, injury, or other pathological conditions, including the identification and removal of loose or foreign bodies that may be causing pain or dysfunction. The surgical approach typically involves making an incision over the deltoid and pectoral muscles, allowing access to the joint capsule for thorough examination and treatment. This procedure is critical for diagnosing issues such as osteochondral defects, labral tears, and rotator cuff injuries, which can significantly impact a patient's mobility and quality of life.
