CPT 23472: Total Shoulder Arthroplasty, Humeral Head and Glenoid Replacement
CPT code 23472 represents a total shoulder arthroplasty, a surgical procedure that replaces the humeral head and the glenoid cavity with prosthetic components to treat severe shoulder arthritis. Nationally, this procedure is a common intervention for end-stage glenohumeral joint disease and has substantial implications for surgical utilization, postoperative rehabilitation, and device supply chains.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The report summarizes coverage patterns, utilization benchmarks, and the clinical context that informs coding and billing for total shoulder replacement.

Clinical & Coding Specifications
Clinical Context
A 72-year-old patient presents with progressive right shoulder pain, limited range of motion, and nocturnal pain refractory to conservative care including physical therapy, corticosteroid injections, and NSAIDs. Radiographs and CT demonstrate advanced glenohumeral osteoarthritis with joint space loss, humeral head deformity, and glenoid erosion. After preoperative medical optimization and anesthesia clearance, the patient is scheduled for a total shoulder arthroplasty. In the operating room under general anesthesia with regional nerve block, the surgeon performs a deltopectoral approach, resects the arthritic humeral head, prepares the glenoid, and implants prosthetic humeral head and glenoid components. Postoperatively the patient recovers in the PACU, receives multimodal analgesia and physical therapy evaluation, and is discharged to home with outpatient follow-up for wound check and progressive rehabilitation.
