CPT code 23540 denotes the closed, nonoperative treatment of an acromioclavicular (AC) joint dislocation performed without manipulation or surgical intervention. Nationally, this code captures outpatient and urgent management of a common shoulder injury that often presents to emergency departments, urgent care centers, and orthopedic clinics. Accurate use of the code ensures claims reflect conservative management rather than surgical repair, which affects care pathways and billing categorization.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when CPT code 23540 is appropriate, typical sites of service, and common billing considerations. The publication also outlines benchmarking and payer coverage themes relevant to nonoperative shoulder injury management, policy updates that affect documentation expectations, and practical coding distinctions between closed nonoperative treatment and procedures that involve manipulation or surgical intervention.

The report is intended for billing staff, coders, practice managers, and clinicians who need clear guidance on code selection and claim reporting for AC joint dislocations treated without manipulation or surgery. Data not available in the input is noted where applicable.
