What 23455 covers
This open operation stabilizes the front of the shoulder by reattaching the labrum to the glenoid and tightening the capsule. Orthopedic surgeons commonly perform it for recurrent anterior shoulder instability, including instability after dislocation when the labrum and capsule are detached or lax. The repair is performed in an operating room, typically in a facility setting.
Report this code when the operative work includes both anterior capsular tightening and labral repair; a capsule-only repair is a different service. The operative report should document the instability, labral injury, approach, and repairs performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

23455 billing questions
How does this differ from 23450?
This code includes repair of the anterior labrum along with capsular tightening. Code 23450 describes anterior capsular repair without the labral repair.
Can the labral repair be billed separately?
The labral repair is part of this service. Do not report a separate code for that same repair.
When is 29806 considered instead?
Code 29806 describes arthroscopic shoulder capsulorrhaphy. This code represents the open anterior repair, so the documented surgical approach helps distinguish them.
What should the operative report support?
Document the anterior instability, the labral detachment or injury, and the open capsular and labral work performed. The record should make clear that both structures were repaired.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are bilateral procedures and assistants handled?
When performed bilaterally and reported with modifier 50, CMS pays at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation.
