Understanding Humana's Policy for Hetlioz

Humana covers Hetlioz (tasimelteon) under both Medicare Advantage Part D and commercial plans, but every plan maintains its own formulary with specific coverage rules. Your exact requirements depend on whether you have:

  • Humana Medicare Advantage with Part D (most common for seniors)
  • Humana Commercial/Employer plans (working-age adults)
  • Humana Medicaid (varies by state)

Key Policy Features:

  • Hetlioz typically appears on specialty tier (highest copay/coinsurance)
  • Prior authorization required for all indications
  • May be non-formulary on some plans, requiring exception requests
  • 12-month approval periods with annual renewal requirements
Tip: Humana updates formularies monthly. Always verify current status using their drug list search tool before starting the PA process.

Medical Necessity Requirements

Humana's medical necessity criteria align closely with FDA labeling and clinical guidelines. Your prescriber must document:

For Non-24-Hour Sleep-Wake Disorder:

  • Confirmed diagnosis with ICD-10 code G47.24
  • Total blindness (no light perception) - required for most plans
  • Sleep pattern documentation: 2-4 weeks of sleep logs showing daily drift in sleep timing
  • Functional impairment: Impact on work, school, or daily activities
  • Chronicity: Symptoms present for at least 3-6 months

For Smith-Magenis Syndrome (SMS):

  • Genetic confirmation of SMS (17p11.2 deletion or RAI1 mutation)
  • Nighttime sleep disturbances with behavioral impact
  • Age-appropriate formulation: Hetlioz LQ for ages 3-15, capsules for 16+
  • Caregiver burden documentation showing family/school disruption

Clinical Documentation Checklist:

  • Specialist evaluation (sleep medicine, neurology, or psychiatry)
  • Objective sleep data (actigraphy preferred, sleep logs minimum)
  • Prior treatment history with specific outcomes
  • Current medications and contraindications
  • Laboratory results if relevant (liver function for dosing)

Step Therapy and Prior Treatment Documentation

Most Humana plans require documented failure of lower-cost alternatives before approving Hetlioz. The typical sequence:

Required Prior Treatments:

  1. Melatonin trial (most critical)
    • Duration: Minimum 6 months continuous use
    • Dosing: Document various doses and timing attempted
    • Outcome: Specific reasons for inadequacy (no entrainment, side effects, etc.)
  2. Sleep hygiene measures
    • Fixed bedtime routines
    • Light therapy (morning bright light, evening light restriction)
    • Environmental modifications
  3. Other sleep medications (if clinically tried)
    • Sedative-hypnotics, antihistamines, or other agents
    • Document specific reasons for discontinuation

Medical Exception Pathways:

  • Contraindication to melatonin (rare but possible)
  • Intolerance to required step-therapy agents
  • Clinical urgency requiring immediate circadian intervention
From our advocates: We've seen denials overturned when prescribers included specific melatonin dosing details (e.g., "3mg, 6mg, and 9mg nightly for 8 months each, with no improvement in sleep entrainment per sleep logs") rather than vague statements about "melatonin failure."

Prior Authorization Process: Step-by-Step

Step 1: Verify Coverage and Requirements

  • Call Humana Member Services (number on your insurance card)
  • Confirm Hetlioz is on your plan's formulary
  • Request current PA form and submission instructions
  • Ask about any plan-specific requirements

Step 2: Gather Required Documentation

Your prescriber will need:

  • Completed Humana PA form
  • Clinical notes supporting diagnosis
  • Sleep logs or actigraphy data (2-4 weeks minimum)
  • Prior treatment documentation
  • Relevant lab results or imaging

Step 3: Submit Prior Authorization

Submission methods:

  • Electronic: Through Humana's provider portal (fastest)
  • Fax: Use number provided on PA form
  • Mail: To address specified in form instructions

Timeline expectations:

  • Standard review: 7-30 days depending on drug classification
  • Expedited review: 72 hours (when delay could harm health)

Step 4: Follow Up and Track Status

  • Humana provides confirmation numbers for tracking
  • Call Member Services if no response within expected timeframe
  • Request expedited review if medical urgency develops

Common Denial Reasons and How to Fix Them

Denial Reason How to Overturn Required Documentation
Insufficient diagnosis documentation Provide detailed specialist evaluation Sleep study, actigraphy, genetic testing results
Step therapy not met Document specific melatonin trial details Prescription records, pharmacy fills, outcome notes
Age restrictions Verify FDA labeling compliance Birth certificate, appropriate formulation request
Non-formulary status Request formulary exception Medical necessity letter, no suitable alternatives
Quantity limits exceeded Justify dosing based on weight/severity Clinical rationale, FDA dosing guidelines
Missing specialist requirement Obtain evaluation from required provider Sleep medicine, neurology, or psychiatry consultation

Appeals Process in Texas

If Humana denies your Hetlioz PA, Texas law provides strong appeal rights with specific timelines:

Internal Appeal (Level 1)

  • Deadline: 60 days from denial notice
  • Timeline: 30 days for standard review, 72 hours for expedited
  • Requirements: Written request with supporting clinical evidence
  • Contact: Use appeals information in your denial letter

External Review (Level 2)

If internal appeal fails, Texas offers independent review:

  • Eligibility: Medical necessity denials qualify
  • Timeline: Request within 4 months of final internal denial
  • Process: Independent Review Organization (IRO) conducts review
  • Binding: IRO decisions are final and binding on Humana
  • Cost: Free to patients (insurer pays IRO fees)

Expedited Appeals

Available when delays could "seriously jeopardize your life, health, or ability to regain maximum function":

  • Prescriber support: If your doctor requests expedited review, Humana must grant it
  • Timeline: 72 hours for decision at each level
  • Concurrent filing: Can file expedited external review simultaneously with internal appeal

Frequently Asked Questions

Q: How long does Humana's prior authorization process take for Hetlioz? A: Standard PA reviews take 7-30 days depending on your plan type. Part D drug requests typically receive decisions within 7 days, while Part C medical benefits may take up to 30 days. Expedited reviews are completed within 72 hours when medically justified.

Q: What if Hetlioz isn't on my Humana formulary? A: You can request a formulary exception by having your prescriber demonstrate that no covered alternatives are as safe and effective for your condition. Include documentation of why switching to a formulary drug would cause potential harm.

Q: Can I get emergency supplies while waiting for PA approval? A: Humana Medicare plans typically offer 31-day transition supplies when switching plans or care settings. For urgent situations, request expedited PA review, which requires a decision within 72 hours.

Q: Does step therapy apply if I tried melatonin with a different insurance company? A: Yes, prior treatment history from other insurers generally counts toward step therapy requirements. Ensure your prescriber includes detailed documentation of previous trials, including dates, doses, and outcomes.

Q: What's the difference between Hetlioz and Hetlioz LQ coverage? A: Both require PA, but age restrictions differ. Hetlioz LQ is only covered for SMS patients ages 3-15, while capsules are for ages 16+. They're not interchangeable formulations.

Q: Can I appeal to Texas state regulators if Humana denies my appeal? A: Yes, Texas offers independent external review through IROs contracted by the Texas Department of Insurance. This review is binding and free to patients. You can also file complaints with TDI if you believe Humana violated state insurance laws.

Q: How often do I need to renew Hetlioz prior authorization? A: Most Humana approvals are for 12 months, requiring annual renewal with updated clinical documentation demonstrating continued medical necessity and treatment response.

Q: What should I do if my prescriber won't complete the PA paperwork? A: Contact Counterforce Health or similar advocacy services that help clinicians prepare comprehensive PA submissions. You can also ask to speak with the practice's prior authorization specialist or request a referral to a provider experienced with Hetlioz prescribing.
