About 23552: Open acromioclavicular reconstruction with graft
Open reconstruction of an acromioclavicular separation using a graft, reported when operative treatment addresses an acute or chronic dislocation.
An orthopedic surgeon uses an open approach to reduce and reconstruct a dislocated acromioclavicular joint with a graft. The procedure may be performed for an acute separation or a chronic separation requiring operative reconstruction; the graft helps restore support across the joint. The code applies to the acromioclavicular joint, where the clavicle meets the acromion, not the sternoclavicular joint or a clavicle fracture.
Report this code when the operative record supports open treatment of the acromioclavicular dislocation and graft use. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

Does the code include harvesting the graft?
The graft reconstruction is part of the service. Document the graft used and the open treatment performed; do not assume a separately reportable harvest service from the graft use alone.
When should 23545 be considered instead?
23545 is for closed treatment of an acromioclavicular dislocation with manipulation. This code is for open treatment with graft reconstruction.
What does the 90-day global period include?
It includes the day-before preoperative visit and 90 days of related postoperative care.
Can this be reported for both shoulders?
For bilateral treatment, CMS pays the procedure with modifier 50 at 150%. The operative documentation should support treatment of both sides.
