Why Hip Replacement Is Denied in Washington State

• Conservative treatment not documented: Insurers require proof of failed physical therapy (typically 3–6 months), NSAIDs, and corticosteroid injections before approving hip replacement.
• Medical necessity disputes: The insurer's reviewing physician applies internal clinical criteria to override your orthopedic surgeon's recommendation.
• Radiographic threshold requirements: Plans require X-rays showing specific degrees of joint degeneration — typically Kellgren-Lawrence Grade 3–4 osteoarthritis.
• Functional status arguments: Insurers claim your functional limitations don't meet threshold criteria for surgical intervention.
• BMI restrictions: Some Washington plans require weight management participation before hip replacement approval.
• Out-of-network provider: Using a non-network orthopedic surgeon or facility increases denial risk.
