CPT® Code 23530

The procedure described by CPT® Code 23530 refers to the open treatment of an acute or chronic dislocation of the sternoclavicular joint (SCJ). The SCJ is a critical joint located at the junction of the clavicle and the sternum, allowing for a wide range of motion necessary for arm and shoulder movement. This joint is classified as a saddle-type joint, which provides the ability to move in multiple planes, particularly facilitating the forward thrust of the arm and shoulder. The stability of the SCJ is largely dependent on the integrity of its joint capsule and the surrounding ligaments. When a dislocation occurs, it can be either acute, resulting from a sudden injury, or chronic, developing over time due to repetitive stress or instability. The open treatment involves a surgical approach where a skin incision is made over the SCJ, allowing for the dissection of overlying soft tissue structures to expose the joint capsule. The dislocated joint is then reduced and stabilized using sutures, ensuring proper alignment and function. This procedure may involve drilling holes in both the clavicle and the manubrium to facilitate the secure placement of sutures, or alternatively, using suture material to wrap and secure the clavicle to the first rib. The goal of this surgical intervention is to restore the normal anatomy and function of the SCJ, thereby alleviating pain and improving mobility.
