What 27400 covers
This operation surgically shortens a thigh muscle or tendon as a reconstructive correction. An orthopedic surgeon typically performs it in an operating room when the treatment plan calls for changing the length of the muscle-tendon unit, rather than repairing a newly ruptured structure. The operative report should identify the treated muscle or tendon, side, reason for shortening, and the work performed.
Select this code when the surgeon performs the thigh muscle or tendon shortening procedure, not a primary or secondary repair of a rupture. The record should make the shortening procedure and its anatomic target clear. It 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% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

This code is for a planned shortening procedure. Use a primary or secondary rupture-repair code when the surgeon is repairing a torn quadriceps or hamstring muscle or tendon.
What should the operative report document?
Document the side, specific thigh muscle or tendon, reason for shortening, and the procedure performed so the record supports the service reported.
Does this code have a global period?
Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is bilateral reporting handled?
CMS lists bilateral reporting with modifier 50, paid at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
