Orthopedic surgery
About 27440: Tibial plateau knee arthroplasty
Reports knee arthroplasty focused on the tibial plateau, rather than replacement of a femoral condyle or a total knee joint.
An orthopedic surgeon performs this operation to reconstruct the knee’s tibial articular surface. It is a joint procedure for selected patients with disease or damage affecting the tibial plateau; it is distinct from replacing the full knee joint or resurfacing both the femoral and tibial sides. The service is generally performed in an operating room, with the operative report identifying the treated surface and the reconstructive work performed.
Select this code when the documented arthroplasty is limited to the tibial plateau. The operative report should support that extent and distinguish it from a broader compartment or total knee replacement. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that 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% reduction. Modifier 50 applies to a bilateral procedure, paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27440 billing questions
How is this different from a total knee replacement?
This code is for arthroplasty focused on the tibial plateau. A total knee arthroplasty replaces the knee more broadly and is reported with 27447.
When should 27441 be considered instead?
27441 is the related tibial plateau arthroplasty code with debridement and partial synovectomy. The operative report must support that additional work.
What operative documentation supports 27440?
Document the knee surface treated, the arthroplasty performed, and the extent of reconstruction. The record should make clear that the service is limited to the tibial plateau.
Are related postoperative visits separately reported during the global period?
The 90-day global period includes the day-before preoperative visit and related postoperative care. The included care is part of the surgical global period.
How does Medicare handle bilateral procedures and other procedures performed in the same session?
A bilateral procedure reported with modifier 50 is paid at 150%. For multiple procedures in the same session, the highest-valued procedure is paid in full and others are paid at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
