Common Denial Prevention Tips

Five Critical Pitfalls to Avoid

  1. Incomplete genetic documentation
    • Fix: Include full laboratory report with variant details and pathogenicity assessment
    • Source: Ensure CLIA-certified lab testing per BCBS medical policies
  2. Missing specialist involvement
    • Fix: Document consultation with appropriate subspecialist (genetics, pediatrics, metabolics)
    • Evidence: Include specialist note confirming diagnosis and treatment plan
  3. Incorrect age/BSA documentation
    • Fix: Provide current measurements with BSA calculation showing ≥0.39 m²
    • Verification: Double-check math and include calculation method
  4. Inadequate clinical justification
    • Fix: Detailed letter explaining disease severity, prognosis, and expected benefits
    • Support: Reference FDA approval and clinical trial data
  5. Wrong submission pathway
    • Fix: Verify your specific plan's PA requirements and submission portal
    • Confirmation: Call plan to confirm current process before submitting
From our advocates: In our experience with rare disease approvals, the most successful cases include a comprehensive genetic report, a detailed specialist letter addressing the plan's specific criteria point-by-point, and proactive communication with the specialty pharmacy to coordinate seamlessly after approval. This approach significantly reduces delays and back-and-forth requests for additional information.
