CPT code 23450: Shoulder stabilization, anterior Putti-Platt repair2026 Medicare rate & RVUs

Medicare pays $871.76 for 23450 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 23450 covers

This open stabilization procedure tightens the front of the shoulder capsule, classically with tightening or overlap of the subscapularis, to limit recurrent anterior translation. An orthopedic shoulder surgeon typically performs it in an operating room for a patient with recurrent anterior shoulder instability when the Putti-Platt technique is used.

Select the code from the operative technique, not simply the diagnosis of shoulder instability. The operative report should identify the anterior capsular repair, the technique performed, the side, and any separately described labral work. The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery. For multiple procedures in the same 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%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
