Medical Necessity Letter Requirements

Your CF specialist's letter should include these essential elements:

Clinical Documentation Checklist

  • ✅ Confirmed CF diagnosis: Sweat chloride test results and/or clinical presentation
  • ✅ Genetic testing: Laboratory report showing F508del or other responsive CFTR mutation
  • ✅ Patient age: Confirm patient is 2 years or older
  • ✅ Prior therapies: Document previous CFTR modulators tried, failed, or inappropriate
  • ✅ Current clinical status: FEV1, nutritional status, pulmonary exacerbations
  • ✅ Treatment goals: Expected clinical outcomes with Trikafta therapy
  • ✅ Monitoring plan: Commitment to FDA-required liver function monitoring

Supporting Evidence to Include

  • Recent clinic notes documenting CF progression
  • Pulmonary function test results
  • Laboratory values (liver function, vitamin levels)
  • Documentation of previous medication failures or intolerances
  • Reference to FDA-approved indications
Clinician Tip: The strongest letters reference specific sections of the FDA label and include exact genetic test results with mutation names. Humana reviewers look for precise documentation that matches FDA-approved criteria.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documents
"Genetic testing not provided" Submit complete genetic analysis Lab report with specific mutations listed
"Step therapy not completed" Request exception based on clinical urgency Letter explaining why alternatives are inappropriate
"Not medically necessary" Provide CF specialist attestation Enhanced clinical documentation with guidelines
"Age requirement not met" Verify birth date and FDA approval Patient demographics and FDA label reference
"Incomplete prior authorization" Resubmit with all required fields Complete PA form with attachments

Most Effective Appeal Strategy

Focus on FDA compliance and standard of care. Trikafta is the gold standard for eligible CF genotypes, and denial often stems from incomplete documentation rather than legitimate medical concerns.

California Appeals Process

California offers one of the strongest patient protection systems in the country through Independent Medical Review (IMR).

Internal Appeal with Humana (Required First Step)

  • Timeline: Must file within 60 days of denial
  • Process: Submit additional documentation to same PA fax number
  • Decision: Humana has 30 days to respond
  • Expedited: Available for urgent situations (72-hour decision)

California Independent Medical Review (IMR)

  • When: After internal appeal is denied or if Humana doesn't respond in 30 days
  • Timeline: File within 180 days of original denial
  • Cost: Free to patients
  • Process: Independent physicians review your case
  • Decision: Binding on Humana if approved
  • Success Rate: High for well-documented cases with clear medical necessity

How to File IMR

  1. Online: DMHC IMR application
  2. Phone: Call DMHC Help Center at 888-466-2219
  3. Mail: Download forms from DMHC website

Required Documents for IMR:

  • Copy of original denial letter
  • All medical records related to CF diagnosis and treatment
  • Genetic test results
  • CF specialist's letter supporting Trikafta necessity
  • Any additional clinical evidence
California Advantage: The DMHC Help Center can assist with paperwork and provide guidance throughout the process. They're particularly helpful for complex cases involving rare disease medications like Trikafta.

Frequently Asked Questions

How long does Humana prior authorization take for Trikafta?

Standard review takes up to 14 days, but expedited review is available for urgent situations and typically decided within 72 hours. Your CF specialist can request expedited review if delays would harm your health.

What if Trikafta is non-formulary on my Humana plan?

You can request a formulary exception with supporting documentation from your CF specialist. If denied, the California IMR process can override non-formulary decisions when medically necessary.

Can I get an expedited appeal in California?

Yes, both Humana internal appeals and California IMR offer expedited processes for urgent medical situations. Expedited IMR decisions are made within 7 days.

Does step therapy apply if I've used CFTR modulators outside California?

Previous therapy records from any state count toward step therapy requirements. Ensure your CF specialist includes complete medication history in the prior authorization request.

What happens if my genetic test shows an unclear mutation?

If your mutation status is uncertain, request an FDA-cleared CFTR mutation panel to confirm eligibility. Humana cannot deny based on incomplete genetic information if testing is pending.

How much will Trikafta cost with Humana coverage?

Costs depend on your specific plan's specialty tier coinsurance, typically 25-40% of the drug cost. Contact Humana member services for your exact copay amount and annual out-of-pocket maximum.

Can I appeal if I'm new to Humana and was already taking Trikafta?

Yes, and Humana may provide temporary coverage during the transition period. File for prior authorization immediately and request expedited review to avoid interruption.
