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

What 23540 covers

This service covers definitive nonoperative care for an acromioclavicular (AC) joint dislocation, the separation between the distal clavicle and the acromion. An orthopedic surgeon or other qualified physician may manage a traumatic AC separation with measures such as immobilization and a treatment plan that avoids joint manipulation. The code is specific to the AC joint, not a sternoclavicular dislocation or a clavicle fracture.

Report it when the physician assumes treatment of the dislocation without manipulating it; documentation should identify the injury and side, the treatment decision, and the nonoperative plan. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For bilateral treatment reported with modifier 50, CMS pays at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
