How to Get Symdeko/Symkevi (Tezacaftor/Ivacaftor) Covered by Humana in Illinois: Complete Appeals Guide with Forms and Timelines

Answer Box: Getting Symdeko/Symkevi Covered by Humana in Illinois

Humana typically requires prior authorization for Symdeko/Symkevi (tezacaftor/ivacaftor) and often classifies it as non-formulary, requiring a formulary exception. To get coverage in Illinois: (1) Submit a complete prior authorization with CF diagnosis, CFTR genotype showing F508del mutation, age ≥6 years, and specialist letter; (2) If denied, file internal appeal within 65 days; (3) Request Illinois external review within 30 days of final denial through the Illinois Department of Insurance. Success rates improve significantly with complete documentation upfront.

"Age requirement not met" Verify patient age ≥6 years Birth certificate or medical records
"Step therapy required" Document prior therapy failures/intolerances Treatment history, adverse event documentation
"Non-formulary drug" Request formulary exception Medical necessity letter explaining why alternatives inadequate

Clinician Corner: Medical Necessity Letter Checklist

Your CF specialist's letter should include:

  • Patient's specific CF genotype (F508del + responsive mutation)
  • Current clinical status (FEV1, BMI, exacerbations, hospitalizations)
  • Prior CFTR modulator experience (if any) and outcomes
  • Why Symdeko/Symkevi is appropriate for this genotype
  • Expected clinical benefits and monitoring plan
  • Citations: FDA prescribing information, CF Foundation guidelines

Costs & Patient Assistance

Symdeko/Symkevi's list price is approximately $323,491 annually, but several programs can help:

Manufacturer Assistance

  • Vertex Patient Services: Copay support and free drug programs
  • Contact: Through prescriber or Vertex website (verify current programs)

Foundation Support

  • CF Foundation Compass: Financial navigation and emergency assistance
  • Other rare disease foundations: May provide grants for CF medications

Illinois-Specific Resources

  • Illinois Department of Healthcare and Family Services: For Medicaid coverage questions
  • Illinois 211: Dial 2-1-1 for local assistance programs
From our advocates: We've seen cases where patients initially denied for "incomplete genotype documentation" were approved within days once the CF center submitted a comprehensive CFTR report clearly showing F508del mutations. The key is ensuring your genetic testing explicitly states the mutations rather than just referencing variant numbers.
