Orthopedic surgery
About 23800: Glenohumeral joint fusion
Reports surgical fusion of the glenohumeral joint without bone graft, typically to stabilize a severely painful or nonfunctional shoulder.
An orthopedic surgeon fuses the humeral head to the glenoid by preparing the joint surfaces and stabilizing them so they heal together. This operation may be chosen for a severely painful, unstable, or nonfunctional shoulder when preserving motion with an implant is not the treatment plan. It is generally performed in an operating room under anesthesia, with fixation selected for the patient’s anatomy and condition.
Report this code when the glenohumeral fusion is performed without bone graft; the grafted fusion is represented by a different code in this family. The operative report should identify the joint fused, the fusion work and fixation performed, whether graft was used, and the clinical indication. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session procedures, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 applies to bilateral reporting, paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
