Medical Necessity Letter Essentials

Your physician's medical necessity letter is crucial for approval. Here's what Cigna expects:

Core Components

Patient Summary:

  • Confirmed diagnosis with ICD-10 code
  • Disease severity and functional impact
  • Treatment goals and expected outcomes

Prior Therapy Documentation:

  • Each medication tried (name, dose, duration)
  • Specific reason for discontinuation
  • Adverse events or contraindications
  • Clinical response or lack thereof

Clinical Justification:

  • Why Ilaris is medically necessary
  • Reference to FDA labeling and clinical guidelines
  • Specialist recommendation and monitoring plan

Supporting Evidence:

  • Recent laboratory values
  • Objective disease activity measures
  • Quality of life impact
  • Risk of delaying treatment
From our advocates: We've seen the strongest approvals when physicians include specific inflammatory marker trends (CRP, ESR) and cite current ACR or EULAR guidelines. A clear timeline showing disease progression despite standard therapies significantly strengthens the case.
