Common Denial Prevention Tips

Five Critical Pitfalls to Avoid

  1. Incomplete Genetic Documentation
    • Pitfall: Submitting without specific enzyme defect confirmation
    • Prevention: Include complete genetic testing report with specific mutations identified
  2. Missing Vitamin Trial Documentation
    • Pitfall: No evidence of B6, B12, folate therapy attempts
    • Prevention: Document specific doses, durations, and clinical response to each vitamin
  3. Non-Specialist Prescriber
    • Pitfall: Primary care provider without metabolic expertise
    • Prevention: Ensure prescription from geneticist or metabolic specialist
  4. Inadequate Lab Values
    • Pitfall: Normal or borderline homocysteine levels
    • Prevention: Submit multiple elevated homocysteine measurements over time
  5. Exceeding FDA Dosing
    • Pitfall: Requesting >20 grams daily without justification
    • Prevention: Stay within FDA-approved dosing limits or provide exceptional clinical rationale

From our advocates: We've seen several homocystinuria cases succeed in external review when the initial denial was based on incomplete genetic documentation. The key was providing comprehensive genetic testing results and detailed vitamin therapy failure records. While outcomes vary, thorough documentation significantly improves your chances with the independent reviewers.

Success Rates and Expectations

Based on historical Smart NC data, external reviews overturn insurer denials in approximately 20-25% of cases. Success depends heavily on:

  • Completeness of clinical documentation
  • Strength of genetic and biochemical evidence
  • Clear demonstration of medical necessity
