What 24320 covers
Code 24320 represents an operative tenoplasty on a tendon in the elbow-to-shoulder region, reported for each tendon treated. The surgeon reconstructs or reshapes tendon tissue; the procedure is distinct from tendon release, lengthening, transfer, fixation, or a separately defined tendon or muscle repair. Orthopedic surgeons and upper-extremity specialists typically perform it in an operating-room setting when the operative plan calls for tenoplasty of a tendon in this region.
The operative report should identify the tendon and site, describe the reconstructive work performed, and support the number of tendons treated. This major-surgery code has 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% multiple-procedure reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this descriptor and anatomy.

How to choose
- 24305Tendon lengthening
- 24305 is for lengthening a tendon. Choose 24320 when the documented procedure is tenoplasty, not tendon lengthening.
- 24310Open tenotomy
- 24310 describes open tenotomy, or tendon release. It is not the choice for reconstructive or reshaping work reported as tenoplasty.
- 24341Tendon/muscle repair
- 24341 covers a defined tendon or muscle repair in the upper arm or elbow. Distinguish it from tenoplasty by the procedure actually documented.
- 24340Biceps tenodesis
- 24340 is for biceps tendon fixation at the elbow. Use 24320 for tenoplasty of a tendon rather than that fixation procedure.
24320 billing questions
How is tenoplasty different from tendon repair?
Use 24320 when the documented operation is a tenoplasty. When the surgeon performs the separately defined repair of a tendon or muscle in the upper arm or elbow, consider 24341 instead.
Should 24320 be reported per tendon?
Yes. The code is reported for each tendon treated, so the operative report should identify the tendon or tendons and the work performed on each.
Can modifier 50 be used when both elbows are treated?
No. CMS identifies bilateral adjustment as inappropriate for this descriptor and anatomy; modifier 50 should not be used.
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 or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
