What 27570 covers

An orthopedic surgeon manipulates the knee while the patient is under anesthesia to address substantial stiffness or restricted range of motion. A common setting is a hospital or ambulatory surgery center, including treatment of persistent stiffness after knee replacement. The service is a closed manipulation; it does not describe arthroscopic release of adhesions or an open lengthening procedure.

Report the service when the operative note supports manipulation under anesthesia and identifies the treated knee and the motion limitation addressed. Related postoperative visits are included in the 10-day global period. 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. For bilateral manipulation, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this code; 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.
