Orthopedic surgery
About 27442: Knee joint arthroplasty revision
Reports operative revision arthroplasty of the knee joint, generally performed by an orthopedic surgeon when the joint requires reconstructive surgical treatment.
This code represents an operative revision arthroplasty involving the knee joint. An orthopedic surgeon typically performs the procedure in a hospital or ambulatory surgery facility, addressing a joint that needs reconstructive surgical treatment. The operative report should make clear what was revised and the work performed; a ligament reconstruction, patellar realignment, or routine primary total knee replacement is a different service.
Report the code when the documented operation supports this knee-joint revision service, rather than selecting it from the diagnosis alone. CMS assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

27442 billing questions
How is this code different from a total knee replacement?
This code represents revision arthroplasty of the knee joint. A primary replacement of both knee compartments is reported with 27447 when the operative service meets that code’s criteria.
Does the 90-day global period include postoperative visits?
Yes. Related postoperative care for 90 days is included, along with the preoperative visit on the day before surgery.
How are other procedures performed in the same session paid?
The highest-valued procedure is paid in full; other procedures are subject to the standard multiple-procedure reduction, with payment at 50%.
Can modifier 50 be used for bilateral surgery?
CMS identifies this as a bilateral procedure; reporting with modifier 50 is paid at 150%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
What should the operative report establish?
Document the knee-joint revision performed and the operative work supporting this service. The diagnosis by itself does not establish which procedure code applies.
