Revision Knee Replacement Surgery
What is this procedure?
Surgical revision of a previously implanted total knee prosthesis when the original replacement has failed due to wear, loosening, infection, instability, or fracture around the implant. Revision surgery is more complex than primary replacement and involves removing the failed components, addressing bone loss, and implanting new prosthetic components.
Does this require prior authorization?
Medical Necessity Tips
What clinical evidence supports approval
