Essential Documents Checklist

Medical Documentation:

  • Genetic testing report confirming exon 45 mutation
  • Current neurologist evaluation notes

Clinician Corner: Medical Necessity Letter

Your prescriber's letter should address these key points:

  • Diagnosis confirmation: "Patient has genetically confirmed DMD with mutation amenable to exon 45 skipping therapy"
  • Clinical rationale: Current functional status and treatment goals
  • Monitoring plan: Commitment to monthly urine protein monitoring and quarterly cystatin C levels
  • Alternative therapies: Documentation of current/prior treatments and their limitations
Tip: Request your genetic testing lab to specifically state "amenable to exon 45 skipping" rather than just listing the mutation. This exact phrasing helps avoid denials.

From Our Advocates

"We've seen families succeed by staying organized and persistent. One Ohio family we worked with was initially denied because their genetic report didn't use the exact phrase 'amenable to exon 45 skipping.' After getting a clarifying letter from the lab, their appeal was approved within two weeks. The key was addressing the specific denial reason rather than just resubmitting the same paperwork."
