About 27391: Open multiple thigh tendon tenotomy
Reports open division of multiple thigh tendons, such as for operative release, when the documented tendon work matches this code rather than a single-tendon procedure.
This code describes an open tenotomy: the surgeon exposes and divides multiple tendons in the thigh to release them. Orthopedic surgeons, including pediatric orthopedic surgeons, may perform tendon releases for contracture or restricted movement. The operative report should identify the tendons treated, the open approach, and the reason for release; the code is not a tendon repair or a lengthening procedure.
Choose this code when the documented work matches the multiple-tendon service in its full CPT descriptor. Distinguish it from the single-tendon code and from codes for tendon lengthening. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Do not append modifier 50; the descriptor or anatomy is unsuitable for bilateral adjustment. Assistant-at-surgery and co-surgeon payment require supporting documentation, and team surgery is not permitted.

27391 billing questions
How does this differ from 27390?
27391 represents multiple thigh tendons, while 27390 is the related single-tendon service. Follow the full CPT descriptor and the operative report’s description of the tendons divided.
Is tendon lengthening reported with this code?
No. This service is tendon division or release; use the appropriate lengthening code when the surgeon lengthens the tendon instead.
What documentation supports reporting multiple tendons?
Document the open approach, the specific tendons divided, and the clinical reason for release. The record should support more than a single-tendon procedure.
Can modifier 50 be appended when both sides are treated?
No. CMS identifies this descriptor or anatomy as unsuitable for bilateral adjustment, so modifier 50 is inappropriate.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
