How to Use This Decision Tree

This guide helps Michigan patients and clinicians navigate Cigna's specific requirements for Xyrem (sodium oxybate) coverage. Start with the eligibility check below, then follow your pathway to approval or appeals.

Before you begin: Gather your insurance card, recent sleep study results, medication history, and any previous denial letters. Xyrem costs approximately $18,968 per 3×180 mL supply without coverage, making proper authorization crucial.

Eligibility Quick Check

Answer these questions to determine your coverage pathway:

✅ Likely Eligible if you have:

  • Sleep study documentation (PSG + MSLT showing ≤8 minutes mean sleep latency + ≥2 SOREMPs)
  • Age 7 years or older
  • Documented trial/failure of stimulants (dextroamphetamine) OR medical contraindication
  • Prescription from sleep specialist, neurologist, or psychiatrist
  • Willingness to enroll in REMS program

⚠️ Possibly Eligible if you have:

  • Narcolepsy symptoms but incomplete sleep studies

❌ Not Yet Eligible if you have:

  • No confirmed narcolepsy diagnosis

From Our Advocates

We've seen Michigan patients successfully overturn Xyrem denials by focusing on three key elements: comprehensive sleep study documentation, detailed medication trial history, and clear articulation of functional impairment. One effective approach involves having the sleep specialist write a detailed letter explaining why alternatives are inadequate for the patient's specific presentation. This personalized clinical rationale often resonates with reviewers more than generic medical necessity language.
