What 27390 covers

This operation releases one adductor tendon at the hip through an open surgical approach. Orthopedic surgeons commonly perform it when adductor tightness or contracture limits hip positioning, including in patients with spasticity. The operative report should identify the adductor tendon treated and establish that the surgeon used an open approach; a percutaneous release is coded differently.

Report this code for one tendon, not a multiple-tendon release or a hamstring procedure. Documentation should describe the operative site, tendon released, approach, and reason for the release. CMS classifies the service as major surgery with a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral surgery, modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
