What 23545 covers
This service treats a dislocation of the acromioclavicular joint, where the clavicle meets the acromion, by manipulating the joint to restore alignment without open repair. An orthopedic surgeon commonly performs it in an acute-care or surgical setting. The patient may then be immobilized, for example in a sling, as part of the treatment plan.
Choose this code when the physician performs manipulation as part of closed treatment; treatment without manipulation is represented by a different code. Document the dislocation, the side, the manipulation and reduction performed, and the resulting treatment plan. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

- This code is for closed treatment with manipulation. Code 23550 is for open treatment of the AC dislocation.
- 23552AC joint reconstruction
- This code describes closed manipulation. Code 23552 is used for open treatment involving a graft.
- 23525Joint reduction

23545 billing questions
How does this differ from 23540?
Use 23545 when manipulation is performed as part of closed treatment of the AC dislocation. Code 23540 represents closed treatment without manipulation.
When would an open-treatment code be more appropriate?
Use an open-treatment code when the surgeon treats the AC dislocation through an open approach, rather than by closed manipulation. Code 23550 covers open treatment without the graft distinction found in 23552.
What documentation supports reporting this code?
Document the AC dislocation, laterality, the manipulation performed to reduce it, and the post-treatment plan. The record should make clear that manipulation was part of the closed treatment.
How is bilateral treatment handled?
For bilateral procedures, CMS specifies modifier 50 and payment at 150%. Document the treatment performed on each side.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. Related routine follow-up during that period is included in the global service.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. CMS does not permit co-surgeons or team surgery for this code.
