First, confirm your plan type. Humana Medicare Advantage plans with Part D coverage treat Hetlioz as a specialty drug requiring prior authorization. Call the number on your insurance card to verify:

  • Your specific plan includes Part D pharmacy benefits
  • Hetlioz is on your formulary (may be non-formulary on some plans)
  • Your prescribing doctor is in-network
Note: If Hetlioz is completely non-formulary, you'll need to request a formulary exception rather than standard prior authorization.

California-Specific Appeals: DMHC Independent Medical Review

  • Denial was based on "not medically necessary" or "experimental/investigational"
  • You've completed Humana's internal appeal process

IMR Success Rates for Specialty Drugs

Recent DMHC data shows strong overturn rates for medically necessary treatments:

  • 55% of medical necessity denials overturned by independent reviewers
  • 25% reversed by plans during the IMR process
  • Combined success rate of approximately 80% for well-documented cases

How to File IMR

  1. Contact DMHC Help Center
  2. Submit Required Documents
    • Completed IMR application
    • All denial and appeal letters from Humana
    • Medical records supporting necessity
    • Treating physician letter explaining why Hetlioz is medically necessary
  3. Timeline Expectations
    • Standard IMR: Decision within 45 days
    • Expedited IMR: Decision within 72 hours for urgent cases
    • Binding decision: Humana must implement favorable IMR decisions within 5 working days

What if Hetlioz is non-formulary on my plan? You can request a formulary exception with documentation that formulary alternatives are ineffective or contraindicated. The process is similar to PA but requires stronger medical necessity justification.

Does step therapy apply if I failed treatments with a previous insurer? Yes, prior therapy failures from other insurers count if properly documented with dates, dosages, and reasons for discontinuation.

What's the difference between Hetlioz capsules and Hetlioz LQ? Hetlioz capsules are for patients ≥16 years; Hetlioz LQ oral suspension is for ages 3-15 years with Smith-Magenis syndrome. They are not interchangeable.

How much does Hetlioz cost without insurance? Retail prices typically range from approximately $5,895 for 30 capsules to $24,678 for Hetlioz LQ, though costs vary by pharmacy and location.
