What 27175 covers

This code represents closed treatment of a slipped capital femoral epiphysis when the surgeon does not manipulate the displaced femoral head. Orthopedic surgeons commonly use it for in-situ stabilization, often with percutaneous fixation, in an adolescent with a stable slip. The service is performed in an operative setting; the key distinction is treatment without manipulation, not a particular slip severity or implant choice.

Select this code when the operative record supports closed treatment without manipulation, and document the diagnosis, affected side, approach, and whether manipulation was performed. The 90-day global period includes the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; 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.
