Coverage for lower extremity major joint replacement (hip and knee) is subject to the reasonable and necessary requirements of Local Coverage Determination L36007; services meeting LCD L36007 criteria are covered.
Simultaneous bilateral hip or knee replacement during the same encounter is covered when medical necessity for bilateral procedure is documented; bilateral procedures are subject to bilateral pricing.
Total hip arthroplasty (THA) or total knee arthroplasty (TKA) is covered for advanced joint disease when arthritis of the hip or knee is supported by X-ray or MRI demonstrating subchondral cysts, subchondral sclerosis, periarticular osteophytes, joint subluxation, joint space narrowing, or avascular necrosis.
THA or TKA is covered when the patient has pain or functional disability at the hip or knee, e.g., pain interfering with activities of daily living (ADLs), pain increased with initiation of activity, or pain increased with weight bearing.
THA or TKA is covered when there is documentation of unsuccessful conservative therapy appropriate to the episode of care, generally a reasonable attempt of usually 3 months or more (e.g., trial of NSAIDs or supervised physical therapy, or documented contraindication to such therapy).
THA or TKA is covered for other LCD-indicated causes when appropriate supporting evidence is documented, e.g., malignancy of the joint supported by pathology and oncology referral, or fracture supported by X-ray.
