Read the Denial: Understanding Aetna's Decision

When Aetna CVS Health denies Hetlioz coverage, your denial letter will contain specific reason codes. Common denial reasons include:

Medical Necessity Denials:

  • Insufficient documentation of total blindness for Non-24
  • Missing genetic confirmation for Smith-Magenis Syndrome
  • Lack of sleep specialist involvement
  • Inadequate melatonin trial documentation

Administrative Denials:

  • Non-formulary status without exception request
  • Quantity limits exceeded
  • Age restrictions not met
  • Missing prior authorization
Tip: Look for the specific denial code and reference policy number in your letter. This tells you exactly which criteria weren't met and guides your appeal strategy.

The denial letter will also specify your appeal deadlines. For Aetna CVS Health members in Michigan, you have 180 calendar days from the denial date to file your first internal appeal.

Fixable Causes: Common Issues and Quick Solutions

Many Hetlioz denials can be overturned by addressing specific documentation gaps:

Missing Specialist Documentation

Problem: PA submitted by primary care physician Solution: Obtain consultation note from board-certified sleep medicine, neurology, or genetics specialist

Incomplete Diagnosis Documentation

Problem: Chart notes don't clearly establish total blindness or SMS Solution: Request ophthalmology report confirming "no light perception" or genetic testing results showing 17p11.2 deletion/RAI1 mutation

Insufficient Prior Therapy Records

Problem: Melatonin trial not documented or too brief Solution: Gather pharmacy records showing at least 30-day melatonin trial with specific doses, dates, and failure reasons

Wrong Formulation Request

Problem: Requesting capsules for patient under 16 or suspension for adult Solution: Verify age-appropriate formulation per FDA labeling

First-Level Appeal: Building Your Case

Your internal appeal to Aetna CVS Health must address every denial reason point-by-point. Here's what to include:

Required Documentation Checklist

  • Complete appeal form (available through Aetna provider portal)
  • Original denial letter
  • Sleep specialist consultation note
  • Diagnosis confirmation (ophthalmology report or genetic testing)
  • Melatonin trial documentation with failure reasons
  • Current sleep logs or actigraphy data
  • Medical necessity letter addressing all PA criteria

Medical Necessity Letter Components

Your specialist should include:

  1. Patient identification and diagnosis with ICD-10 codes (G47.24 for Non-24, Q93.88 for SMS)
  2. Clinical presentation detailing sleep-wake disruption
  3. Prior treatment failures with specific medications, doses, duration, and adverse effects
  4. Medical justification citing FDA labeling and clinical guidelines
  5. Prescriber credentials confirming specialty board certification

Peer-to-Peer Review: Direct Doctor Discussion

If your initial appeal is denied, request a peer-to-peer review. This allows your prescribing specialist to discuss the case directly with an Aetna medical director.

Scheduling the Call

Contact Aetna's provider services line and request a peer-to-peer review for the denied PA. Be prepared to provide:

  • Member ID and PA reference number
  • Prescribing physician's name and NPI
  • Preferred call times and contact number

Preparation Checklist for Your Doctor

  • Patient's complete medical history
  • Specific sleep disorder symptoms and severity
  • Documentation of melatonin trial failure
  • Alternative treatment considerations and contraindications
  • Expected clinical outcomes with Hetlioz
From our advocates: "We've seen peer-to-peer calls succeed when the prescribing specialist can clearly articulate why formulary alternatives failed and provide specific clinical evidence supporting Hetlioz's unique mechanism of action for the patient's condition. Having sleep logs and objective measures ready makes a compelling case."

Michigan External Review: DIFS Process

If Aetna's internal appeals are exhausted, Michigan residents can request an external review through the Department of Insurance and Financial Services (DIFS).

Timeline and Eligibility

  • Filing deadline: 127 days from final internal denial
  • Standard review: Up to 60 days for decision
  • Expedited review: 72 hours if delay poses serious health risk
  • Cost: No fee to consumer

How to File

Submit your request through the DIFS Online External Review Form or call 877-999-6442 for assistance.

Required documents:

  • Final denial letter from Aetna
  • All previous appeal decisions
  • Medical records supporting necessity
  • Physician statement (required for expedited review)

The external review decision is binding on Aetna and typically has higher overturn rates than internal appeals.
