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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

23540 billing questions

How is this code different from 23545?

Use 23540 when the AC dislocation is treated without manipulating the joint. Code 23545 is the corresponding closed-treatment option when manipulation is performed.

Does the global period include follow-up care?

Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

How is bilateral treatment reported?

For treatment of both AC joints, report modifier 50. CMS pays bilateral reporting at 150%.

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.
