What 23466 covers
The surgeon tightens or repairs the glenohumeral capsule to limit abnormal movement in more than one direction. This open stabilization is used for multidirectional shoulder instability, such as recurrent slipping with laxity across several directions of motion. Orthopedic surgeons typically perform it in an operating room. The operative report should identify the instability pattern and describe the capsular work performed; a single-direction repair or a procedure centered on a different structure may point to another code.
Report 23466 for the open capsular stabilization performed for multidirectional instability, supported by the diagnosis and operative details. It has 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 procedure is paid in full and others at 50%. For bilateral surgery, 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.

- Choose 23466 for capsular stabilization addressing instability in multiple directions; 23465 is directed at posterior instability.
- 23455Shoulder stabilizationAnterior repair with labrum
- 23455 describes anterior capsular stabilization with labral repair. 23466 is selected for open stabilization of multidirectional instability.
- 29806Shoulder stabilizationArthroscopic capsulorrhaphy
- Both address shoulder instability, but 29806 is the arthroscopic approach; 23466 describes open capsular stabilization for multidirectional instability.
23466 billing questions
When is 23466 a better fit than an anterior capsular repair?
Use 23466 when the operative indication and capsular work address instability in multiple directions. A repair directed at anterior instability, particularly one with labral repair, is a different service.
How does 23466 differ from posterior capsular repair?
23466 is for multidirectional instability. A procedure directed specifically at posterior instability is represented by 23465.
What documentation supports reporting 23466?
Document the multidirectional instability and describe the open capsular stabilization performed. The operative note should make clear that the procedure addressed instability in multiple directions.
Can modifier 50 be used when both shoulders are treated?
Yes. CMS identifies this as a bilateral procedure; modifier 50 is paid at 150% when performed bilaterally.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
