Medical Necessity Letter Essentials

Clinician Corner: Your medical necessity letter should address Cigna's specific coverage criteria while emphasizing the unique nature of exon 45 skipping.

Essential elements to include:

  • Genetic confirmation: Quote the exact lab result stating "amenable to exon 45 skipping"
  • Failed alternatives: Document trials of corticosteroids or other DMD therapies
  • Functional status: Current 6MWT results and trajectory
  • Specialist oversight: Neurologist or neuromuscular specialist involvement
  • Monitoring plan: Quarterly 6MWT, CK levels, safety assessments

Key talking points:

  • Amondys 45 is the only FDA-approved therapy for exon 45-amenable DMD (~8% of cases)
  • No other exon-skipping therapy targets this specific mutation
  • Early intervention critical before loss of ambulation (median age ~12 years)

Counterforce Health helps clinicians draft evidence-backed medical necessity letters that align with payer-specific requirements, turning complex coverage criteria into clear, compelling clinical narratives.

Common Denial Reasons & Solutions

Denial Reason Solution Required Documentation
Missing genetic confirmation Resubmit with explicit CLIA report Lab stating "exon 45 skipping amenable"
Non-ambulatory status Prove ≥300m on 6MWT Recent functional assessments
Age over 14 Verify birth date; appeal if close Birth certificate, medical records
Insufficient prior therapy Document steroid trials/failures Medication history with dates/outcomes
Site of care issues Justify infusion location Clinical letter supporting home/clinic
Not medically necessary Strengthen clinical rationale Peer-reviewed studies, FDA labeling
From our advocates: We've seen families successfully overturn "experimental" denials by emphasizing that Amondys 45 received full FDA approval (not just compassionate use) and is the standard of care for exon 45-amenable DMD. The key is connecting the genetic test results directly to the FDA indication.

Standard review is 72 hours; expedited review is 24-72 hours. Complex cases may take up to 5-10 business days.

What if Amondys 45 is non-formulary on my plan?
Request a formulary exception through the same PA process. Emphasize that no formulary alternatives exist for exon 45-amenable DMD.

Can I request an expedited appeal?
Yes, if delay would cause serious harm. Document medical urgency in your request to both Cigna and NJ IHCAP.

Does step therapy apply to Amondys 45?
Typically no, since it's mutation-specific. However, Cigna may require documentation of steroid trials or other DMD therapies.

What happens if I move from another state?
New Jersey honors prior authorizations from other states temporarily. Work with your new provider to establish NJ coverage quickly.

How often do appeals succeed for rare disease drugs?
