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

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.
