What 27395 covers
This operation surgically lengthens tendons in the thigh to reduce fixed tightness and improve movement. A typical clinical setting is an operating room, where an orthopedic surgeon treats a contracture affecting knee extension or walking, including hamstring tightness associated with a neuromuscular condition. The operative report should identify the tendons treated and the lengthening performed; a tendon release or transfer is a different service.
Report the code when the documented procedure supports thigh tendon lengthening. CMS assigns a major-surgery global period: the day-before preoperative visit and 90 days of related postoperative care are included. 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. The code is priced as bilateral, so modifier 50 does not increase payment. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 27393Tendon lengthening
- This is a related thigh tendon-lengthening code. Choose between the codes based on the specific procedure and tendon scope documented, not simply the presence of a contracture.
- 27394Tendon lengthening
- This is another related thigh tendon-lengthening code. The operative report must support the particular scope assigned to the selected code.
- 27390Adductor tendon release
- This code describes incision of a thigh tendon. Use it when the documented procedure is an incision or release rather than tendon lengthening.
- 27396Tendon transfer
- This code describes thigh tendon transplantation. It represents tendon transfer, not surgical lengthening.
27395 billing questions
How is this distinguished from codes 27393 and 27394?
Compare the operative report with the specific tendon, extent, and procedure represented by each code. Do not select among these related lengthening codes from the diagnosis alone.
Is a tendon release reported as a lengthening?
Not solely because both procedures address tightness. Codes 27390 and 27391 describe thigh tendon incision procedures; report this code when the documented work is tendon lengthening.
Should modifier 50 be appended for bilateral work?
CMS prices this code as bilateral, and modifier 50 does not increase payment.
What postoperative care is included?
The major-surgery global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard 50% multiple-procedure reduction.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
