CPT® Code 23040

The glenohumeral joint, commonly referred to as the shoulder joint, is a critical component of the shoulder's anatomy, characterized as a shallow ball-and-socket joint. It is formed by the articulation of the glenoid fossa of the scapula and the head of the humerus, allowing for a wide range of motion in the arm. The procedure described by CPT® Code 23040 involves an arthrotomy of the glenohumeral joint, which is an open surgical intervention aimed at exploring, draining, or removing foreign bodies from the joint. This procedure is typically indicated in cases where there is suspicion of infection, accumulation of fluid, or the presence of foreign material within the joint space. The surgical approach begins with an incision over the deltoid and pectoral muscles, followed by careful dissection to access the joint capsule. Once the joint is exposed, the surgeon can perform necessary interventions such as drainage of infected material or removal of foreign bodies, ensuring the joint is thoroughly cleaned and flushed to promote healing. This procedure is essential for restoring function and alleviating pain associated with various shoulder conditions.
