CPT® Code 23473

The procedure described by CPT® Code 23473 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 or glenoid components, severe rotator cuff insufficiency, glenoid bone deficiency, infection, or periprosthetic fractures of the humerus. 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 facilitate access to the joint capsule. The revision process may involve the removal or repositioning of the humeral and/or glenoid components, with the potential use of bone allografts to repair any bone defects. This ensures a secure fit for the new or repositioned components, ultimately aiming to restore shoulder function and alleviate pain for the patient.
