CPT code 23660: Shoulder dislocation2026 Medicare rate & RVUs

Medicare pays $551.11 for 23660 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 23660 covers

An orthopedic surgeon uses an open approach to treat an acute shoulder dislocation, reducing the joint and repairing the associated Bankart lesion when indicated. The service is typically performed in an operating room, most often in a hospital or ambulatory surgery setting. A shoulder dislocation accompanied by a specified humeral fracture may fall under a different fracture-dislocation code rather than this code.

Report 23660 when the operative record supports open treatment of an acute dislocation; the diagnosis alone does not establish that an open procedure was performed. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same 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 available; co-surgeons require supporting documentation, and team surgery is not permitted.

How to choose

23650Shoulder reduction

23650 describes closed manipulation without anesthesia. Choose 23660 when the acute dislocation is treated through an open surgical approach.

23655Shoulder reduction

23655 describes closed manipulation with anesthesia, not open treatment. The procedure performed, rather than anesthesia alone, distinguishes it from 23660.

23670Shoulder surgery

23670 is for open treatment of a shoulder dislocation with a greater tuberosity fracture. Use 23660 for acute open dislocation treatment without that specified fracture pattern.

29806Shoulder stabilization

29806 describes arthroscopic shoulder capsulorrhaphy for instability. It is not the open treatment code for an acute shoulder dislocation.
