(Active) Effective Date: N/A Surgery - Musculoskeletal System Feed
Revision of total knee arthroplasty, with or without allograft; one component
Modifiers may be applicable. Refer to current CPT guidelines for specific modifier usage.
Medical necessity must be established by documenting the patient's symptoms, functional limitations, failed conservative treatments, and the impact on their quality of life. The need for revision should be clearly justified based on the clinical findings.
The surgeon is responsible for removing the damaged or loose prosthesis, preparing the bone, implanting the new component, ensuring proper fixation, managing any bone loss, and closing the incision. They must also address any infection or instability issues.
In simple words: This procedure involves replacing one part of an artificial knee joint with a new one. The surgeon removes the old part, prepares the bone, and puts in the new part. Sometimes, bone from a donor is used to help rebuild the knee.This surgery is more complex than the original knee replacement.
This code represents a revision procedure for a total knee arthroplasty involving a single component. The procedure may or may not utilize an allograft. It includes removing the existing component (femoral, tibial, or patellar), preparing the bone, and implanting the new component.The use of allograft is included in the code. The procedure addresses issues like wear and tear, infection, or instability of the original implant.It's a more complex and time-consuming procedure than a primary knee arthroplasty.
Example 1: A patient presents with a painful, loose femoral component of their total knee prosthesis. The surgeon performs a revision arthroplasty, removing the femoral component and replacing it with a new one., A patient with an infected tibial component undergoes a revision arthroplasty. The infected component is removed, the area is cleaned, and a new tibial component is implanted, possibly with antibiotic-impregnated cement., A patient experiences instability due to a worn patellar component. The surgeon performs a revision arthroplasty, replacing the patellar component and addressing any ligamentous laxity.
Documentation should include the reason for revision (e.g., pain, loosening, infection, instability), operative findings (condition of bone and soft tissues, presence of infection), details of the procedure (component removed, type of new implant, use of allograft, any bone grafting or augments used), and any complications.
