Knee surgery
About 27443: Knee joint revision surgery
Reports revision surgery on the knee joint, with the operative report identifying the revision work performed and the prior procedure or joint condition addressed.
This code represents revision surgery involving the knee joint. Orthopedic surgeons perform these operations in an operating room when prior knee surgery or joint treatment requires revision; the reason may include problems such as loosening, wear, or instability. The operative report should identify the prior work, the current joint findings, and the revision steps performed. The code should not be selected from the word “revision” alone: distinguish it from codes that specifically describe revision of a total knee replacement by the components revised.
Report the service for the documented knee joint revision, using the procedure details to distinguish it from primary knee arthroplasty and more specifically defined revision procedures. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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.

27443 billing questions
How is this code distinguished from 27486 or 27487?
Those codes specifically describe revision of a total knee arthroplasty based on whether one or both components are revised. Use this code only when the documented procedure matches its knee joint revision service rather than a more specifically defined total knee replacement revision.
Is this the code for a primary total knee replacement?
No. Code 27447 describes total knee arthroplasty; this code represents revision work. The operative report should support that the service is a revision rather than a primary replacement.
What documentation supports reporting this code?
Document the prior knee procedure or joint treatment, the current findings, and the specific revision work performed. Those details help distinguish this service from primary arthroplasty and revision codes defined by component count.
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. The global period is tied to this major surgery.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only when supporting documentation is submitted; team surgery is not permitted.
How are bilateral and same-session procedures handled?
Bilateral reporting with modifier 50 is paid at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
