CPT® Code 23474

The procedure described by CPT® Code 23474 refers to the revision of a total shoulder arthroplasty, which is a surgical intervention aimed at correcting issues related to previously implanted shoulder components. This revision may be necessary due to various complications such as loosening of the humeral and/or glenoid components, which can lead to instability and pain in the shoulder joint. Additionally, severe rotator cuff insufficiency or glenoid bone deficiency may necessitate the revision of the glenoid component. Other indications for this procedure include infection and periprosthetic fractures of the humerus, which can compromise the integrity of the shoulder joint and the effectiveness of the initial arthroplasty. The surgical approach typically involves a deltopectoral incision, allowing the surgeon to access the shoulder joint effectively. During the procedure, the surgeon may encounter and address scar tissue, retraction of the conjoint tendon, and the need to incise the subscapularis tendon to gain adequate exposure. The revision process may involve the replacement or repositioning of the humeral and glenoid components, and in cases where bone defects are present, an allograft may be utilized to ensure a secure fit and restore the structural integrity of the shoulder joint. This comprehensive approach aims to alleviate symptoms and restore function to the shoulder following complications from the initial arthroplasty.
