What 23474 covers
An orthopedic surgeon uses this code when revising both components of a prior total shoulder replacement. The operation may address implant loosening, wear, instability, or another failure requiring revision of the humeral and glenoid sides. It is generally performed in an operating room, most often in a hospital or ambulatory surgery setting. A conversion between shoulder replacement designs may qualify when both components are revised.
Select this code based on the components actually revised, not simply the complexity of the case or the original implant type. The operative report should identify the existing arthroplasty and describe revision of both the humeral and glenoid components; it should also document graft use when applicable. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
