What 23406 covers
Code 23406 describes an operation that divides or releases multiple tendons in the shoulder region. An orthopedic surgeon may perform it when a shoulder contracture or deformity requires release of several tendon structures. It is distinct from an operation that repairs a torn rotator cuff or secures a tendon to bone.
Select the code based on the operative report’s account of the shoulder-area tendons released; a release of one tendon points to the single-tendon sibling code. Documentation should identify the treated structures and the operative work performed. 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. The bilateral adjustment does not apply, and modifier 50 is inappropriate. CMS permits assistant-at-surgery payment; co-surgeons and team surgery are not permitted.

23406 billing questions
How does 23406 differ from 23405?
23406 is for release of multiple shoulder-area tendons. Use 23405 when the operative work releases a single tendon.
Does 23406 describe rotator cuff repair?
No. It describes tendon release or division, not repair of a torn rotator cuff. The operative report should support the work actually performed.
Should modifier 50 be appended for both shoulders?
No. CMS identifies the bilateral adjustment as inapplicable to this code and modifier 50 as inappropriate.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon be reported?
CMS permits assistant-at-surgery payment for 23406. Co-surgeons and team surgery are not permitted.
How are other procedures in the same session paid?
CMS applies the standard multiple procedure reduction: the highest-valued procedure is paid in full, and other procedures are paid at 50%.
