Common Denial Prevention Tips

Five Critical Pitfalls to Avoid

  1. Insufficient step therapy documentation: Always provide specific dates, dosages, and outcomes for all prior treatments
  2. Missing quantitative cystine levels: Include actual mg/24h values, not just "elevated"
  3. Incomplete stone analysis: Provide composition analysis confirming cystine stones
  4. Generic medical necessity letters: Customize letters to address Cigna's specific criteria
  5. Wrong submission portal: Use electronic PA systems when possible for faster processing

Strengthening Your Case

  • Include peer-reviewed literature supporting Thiola use in cystinuria
  • Provide genetic testing results if available
  • Document quality of life impact and functional limitations
  • Show compliance with monitoring requirements
