What 27325 covers
This operation excises targeted nerve tissue supplying a hamstring muscle to reduce unwanted muscle overactivity. It is most often considered for a patient with spasticity when hamstring overactivity limits knee extension or affects gait. An orthopedic surgeon or neurosurgeon typically performs the procedure in an operating room, commonly in a hospital or ambulatory surgical facility.
Report this code when the operative work targets the hamstring’s nerve supply; a tendon or fascia release, or a neurectomy at a different nerve site, is a different service. The operative report should identify the nerve target, side, indication, and work performed. CMS classifies the service as major surgery: the day-before preoperative visit and 90 days of related postoperative care are included. For multiple procedures in one 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 made; co-surgeons and team surgery are not permitted.

27325 billing questions
How is this different from a popliteal neurectomy?
This code is for nerve tissue supplying a hamstring muscle. Code 27326 applies when the operative target is the popliteal nerve.
Can a hamstring tendon release be reported as this procedure?
No. This code describes nerve excision, not an incision or release of a hamstring tendon or fascia. Select the code that matches the operative work.
What documentation supports reporting this code?
The operative report should identify the treated side, nerve target, indication, and procedure performed. It should distinguish the nerve work from any separately performed tendon or other procedure.
How should bilateral surgery be reported?
CMS identifies this as a bilateral procedure; modifier 50 is paid at 150%. Document the work performed on each side.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeons and team surgery are not permitted for this code under the CMS rules provided.
