What 23520 covers

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.

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.

23520 billing questions

When should 23520 be chosen instead of 23525?

Report 23520 when the sternoclavicular dislocation is treated closed without manipulation. Choose 23525 when the provider manipulates the joint as part of closed treatment.

How does 23520 differ from open treatment?

23520 describes closed treatment without manipulation. When the provider surgically treats the sternoclavicular dislocation, consider the applicable open-treatment code, such as 23530 or 23532.

What documentation supports reporting 23520?

Document the sternoclavicular joint dislocation, the closed treatment plan, and that the joint was not manipulated. Include the treatment provided, such as immobilization or activity restrictions, when applicable.

What is included in the global period?

CMS assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care.

How is bilateral treatment reported?

For bilateral treatment, CMS pays modifier 50 at 150%. The code's multiple-procedure reduction also applies when other procedures are performed in the same session.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. CMS does not permit co-surgeons or team surgery for this code.

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.
