About 23520: Closed sternoclavicular dislocation treatment without manipulation
Reports closed care of a sternoclavicular joint dislocation when the provider treats the injury without manipulating the joint to reduce it.
This code describes closed treatment of a dislocation where the clavicle meets the sternum, without manipulation of the joint. An orthopedic surgeon or other qualified treating provider may manage the injury with measures such as a sling, activity restrictions, and clinical follow-up. It applies to the sternoclavicular joint, not the acromioclavicular joint at the outer end of the clavicle. The code reflects definitive treatment, rather than simply identifying the injury during an evaluation.
Choose this code when the documented treatment is closed and no manipulation is performed; use the related with-manipulation code when the provider manipulates the joint. Documentation should identify the sternoclavicular dislocation and support the treatment approach. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. 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.
