What 27441 covers
This code represents operative revision of a knee joint. An orthopedic surgeon typically performs the procedure in an operating room when the knee requires surgical revision after prior treatment. The operative report should identify the joint work performed and explain why revision was needed; the code should not be selected from the diagnosis alone.
Report it for the documented revision service, distinguishing it from a primary total knee replacement and from revision codes with more specifically defined work. The code has a 90-day global period, including the day-before preoperative visit and 90 days of 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 reporting with modifier 50, payment is at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

27441 billing questions
How is this distinguished from a primary total knee replacement?
This code is for revision surgery on a knee joint. A primary total knee replacement is reported with 27447 when the documented procedure is primary rather than revision surgery.
What documentation supports reporting this code?
The operative report should describe the revision performed, the knee joint work, and the clinical reason for revising it. The diagnosis by itself does not establish the service.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
How is this code paid when other procedures are performed in the same session?
The highest-valued procedure is paid in full, and other procedures are paid at 50% under the standard multiple procedure reduction.
Can modifier 50 be used for bilateral surgery?
Yes. CMS identifies this as a bilateral procedure; reporting modifier 50 results in payment at 150%.
