Evidence for Medical Necessity

Clinical Documentation Checklist

Medical Necessity Letter Must Include:

  1. Patient-specific details:
    • Confirmed DMD diagnosis with genetic testing results
    • Current functional status with objective measurements
    • Treatment goals and expected outcomes
  2. Clinical rationale:
    • Why Amondys 45 is appropriate for this patient's mutation
    • Evidence of maintained ambulatory function
    • Contraindications to alternative therapies (if applicable)
  3. Supporting evidence:
    • FDA approval letter for exon 45 skipping
    • ESSENCE trial data showing dystrophin increases
    • Current DMD care guidelines supporting antisense therapy
Clinician Corner: Reference the FDA's accelerated approval based on dystrophin production increases, while acknowledging that clinical benefit confirmation is ongoing. Emphasize patient-specific factors that make Amondys 45 the most appropriate treatment option.
