What 23415 covers
The surgeon releases the coracoacromial ligament, which spans the coracoid process and acromion, to increase clearance in the subacromial space. The procedure may include reshaping the acromion. An orthopedic surgeon typically performs it through an open approach during surgery for shoulder impingement, sometimes in the same session as rotator cuff repair.
Report 23415 when the operative work includes an open coracoacromial ligament release; acromioplasty may be performed with it. The operative report should identify the ligament release and any acromial work, rather than relying on an impingement diagnosis alone. 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 other procedures at 50%. For bilateral work reported with modifier 50, CMS pays at 150%. Assistant-at-surgery payment is restricted; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

- 23410Rotator cuff repair
- 23410 reports repair of an acute rotator cuff tear. It does not identify the ligament-release and acromial work described by 23415.
23415 billing questions
Does 23415 include acromioplasty?
Yes. The code covers coracoacromial ligament release with or without acromioplasty, so acromial reshaping performed as part of that service is included.
Can 23415 be reported with a rotator cuff repair?
The codes describe different work: ligament release and acromial work versus tendon repair. Report both only when both services were performed and the applicable coding edits permit separate reporting.
How does 23415 differ from 29826?
23415 describes the open approach. Code 29826 describes arthroscopic subacromial decompression, so the operative approach distinguishes the codes.
What documentation supports 23415?
The operative report should identify the open release of the coracoacromial ligament and describe any acromioplasty performed. A diagnosis of shoulder impingement alone does not establish that the procedure was done.
What are the assistant and co-surgeon payment rules?
CMS does not pay an assistant at surgery for this code. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
