Prior Authorization Process

Step-by-Step: Fastest Path to Approval

  1. Complete REMS Enrollment (Patient and prescriber must both enroll)
  2. Gather Required Documentation
    • Sleep study results (PSG and MSLT)
    • Prior medication trials with documented failures
    • Current narcolepsy diagnosis with ICD-10 codes
  3. Submit Prior Authorization
    • Use Aetna's Availity portal or EMR system
    • Include all supporting documentation with initial submission
    • Timeline: 15 business days for standard review
  4. Track Your Request
    • Follow up within 10 business days if no response
    • Request expedited review for urgent situations (24-72 hours)
Tip: Submit precertification requests at least two weeks in advance for standard processing to avoid treatment delays.

Step Therapy and Clinical Requirements

Aetna implements step therapy protocols requiring documented evidence of therapeutic failures before Xyrem approval. Simply stating prior experience from another insurer is insufficient—Aetna requires comprehensive medical records.

Required Prior Trials

  • Stimulants: Methylphenidate or amphetamine-based medications with documented inadequate response
  • Modafinil/Armodafinil: Trial with documented failure or intolerance
  • Duration: Each trial should be adequate duration at therapeutic doses

Clinical Documentation Needed

  • Confirmed narcolepsy diagnosis with sleep study evidence
  • Polysomnography (PSG) and Multiple Sleep Latency Test (MSLT)
  • Sleep latency ≤8 minutes and ≥2 SOREMPs (Sleep Onset REM Periods)
  • Prior medication history with specific reasons for discontinuation
Clinician Corner: Medical necessity letters should address the specific failure criteria for each prior therapy, include guideline citations from the American Academy of Sleep Medicine, and reference the FDA-approved labeling for Xyrem in narcolepsy treatment.

REMS Enrollment (Required First Step)

Before Aetna will process any authorization, both prescriber and patient must be enrolled in the FDA's XYREM Risk Evaluation and Mitigation Strategy (REMS) program. This is non-negotiable.

Prescriber Enrollment

Patient Enrollment

  • Complete the Patient Enrollment Form
  • Acknowledge understanding of serious risks and safe use conditions
  • Provide insurance and caregiver information if applicable

Contact for REMS questions: 1-866-997-3688

Appeals Process in California

California offers robust patient protections through its dual regulatory system. Most Aetna plans fall under the Department of Managed Health Care (DMHC) oversight.

Internal Appeals (First Level)

  1. File Grievance: Submit within 180 days of denial
  2. Timeline: Aetna has 30 days to respond (expedited: 72 hours)
  3. Required Documents: Denial letter, supporting medical records, prescriber statement

Independent Medical Review (IMR)

If your internal appeal is denied, California's IMR process provides an external review by independent medical experts.

When to Request IMR

  • Denial upheld after internal appeal
  • Plan fails to respond within 30 days
  • Services denied as "not medically necessary" or "experimental"

IMR Process

  • Cost: Free to patients
  • Timeline: 45 days for standard review, 72 hours for expedited
  • Decision: Binding on the insurance plan
  • Success Rate: California IMRs have favorable outcomes for medically justified requests

How to File IMR

  • DMHC Plans: Call DMHC Help Center at 888-466-2219 or visit healthhelp.ca.gov
  • CDI Plans: Contact CDI Consumer Hotline at 800-927-4357
