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.

27570 billing questions
When should this code be chosen instead of arthroscopic lysis of adhesions?
Use this code for manipulation under anesthesia without arthroscopic release. CPT 29884 describes arthroscopic treatment of knee adhesions, with or without manipulation.
What documentation supports reporting the service?
Document the knee stiffness or restricted motion, the knee treated, the manipulation performed under anesthesia, and the clinical result, such as motion before and after the procedure.
Are postoperative visits included?
Related postoperative visits during the 10-day global period are included in this procedure's payment.
How is manipulation of both knees reported?
Report bilateral treatment with modifier 50; CMS pays the bilateral procedure at 150%.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
What happens if another procedure is performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction, with payment at 50%.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
