What 23130 covers
The surgeon removes or reshapes part of the acromion, commonly its prominent undersurface, to relieve narrowing in the subacromial space. Orthopedic surgeons typically perform this operation in a hospital or ambulatory surgical setting for a patient with symptomatic shoulder impingement. It may be performed with a rotator cuff repair when the operative plan includes both procedures. The work may include release of the coracoacromial ligament.
Report 23130 when the operative note documents partial acromial resection or reshaping, not merely inspection of the shoulder or treatment of a separate structure. Document the approach, the portion of acromion treated, and the clinical reason for decompression. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

23130 billing questions
How is 23130 different from arthroscopic subacromial decompression?
23130 describes partial acromial resection performed through an open approach. Arthroscopic decompression is reported with the applicable arthroscopy coding, including 29826 when its requirements are met.
Can 23130 be reported with a rotator cuff repair?
It may be reported in the same session when the surgeon performs and documents acromial resection as distinct work in addition to the cuff repair. The multiple-procedure reduction applies when procedures are performed in the same session.
Does 23130 include distal clavicle excision?
No. Acromial resection treats the acromion; distal clavicle excision treats the clavicle at the acromioclavicular joint. Report each only when the corresponding work is performed and documented.
What should the operative note document?
Document the acromial portion removed or reshaped, the decompression performed, and the reason for the procedure. If a cuff repair or clavicle procedure is also reported, describe its distinct operative work.
How does Medicare handle bilateral reporting and assistants?
Bilateral reporting with modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this code.
What are the co-surgeon and team-surgery rules?
Co-surgeons are paid only when supporting documentation is provided. Team surgery is not permitted.
