What 23660 covers
An orthopedic surgeon uses an open approach to treat an acute shoulder dislocation, reducing the joint and repairing the associated Bankart lesion when indicated. The service is typically performed in an operating room, most often in a hospital or ambulatory surgery setting. A shoulder dislocation accompanied by a specified humeral fracture may fall under a different fracture-dislocation code rather than this code.
Report 23660 when the operative record supports open treatment of an acute dislocation; the diagnosis alone does not establish that an open procedure was performed. This major surgery 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%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

How to choose
- 23650Shoulder reduction
- 23650 describes closed manipulation without anesthesia. Choose 23660 when the acute dislocation is treated through an open surgical approach.
- 23655Shoulder reduction
- 23655 describes closed manipulation with anesthesia, not open treatment. The procedure performed, rather than anesthesia alone, distinguishes it from 23660.
- 23670Shoulder surgery
- 23670 is for open treatment of a shoulder dislocation with a greater tuberosity fracture. Use 23660 for acute open dislocation treatment without that specified fracture pattern.
- 29806Shoulder stabilization
- 29806 describes arthroscopic shoulder capsulorrhaphy for instability. It is not the open treatment code for an acute shoulder dislocation.
23660 billing questions
How is 23660 different from closed treatment codes 23650 and 23655?
23660 is for open surgical treatment of the acute dislocation. Codes 23650 and 23655 describe closed treatment with manipulation, distinguished by whether anesthesia is used.
Does 23660 include repair of a Bankart lesion?
Yes. The open treatment includes Bankart lesion repair; do not report the included repair separately as an additional service.
Which code applies when the dislocation includes a humeral fracture?
Use the applicable fracture-dislocation code when the operative diagnosis and treatment involve a specified fracture. For example, 23670 addresses an associated greater tuberosity fracture and 23680 an associated surgical neck fracture.
What postoperative care is included in the payment?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
How is bilateral treatment handled?
When the procedure is performed bilaterally and reported with modifier 50, CMS pays 150%.
