Do You Qualify for Xyrem Coverage by Humana in Pennsylvania? Decision Tree & Next Steps

Answer Box: Getting Xyrem Covered by Humana in Pennsylvania

You likely qualify if you have confirmed narcolepsy with cataplexy (ICD-10: G47.411), documented sleep study results, and have tried/failed standard therapies. First step: Your prescriber must enroll in the REMS program and submit prior authorization to Humana with clinical documentation. Timeline: 72 hours for standard PA decisions, 24 hours for expedited. If denied, Pennsylvania's new external review program has a 50% overturn rate. Start with the eligibility checklist below.

How to Use This Guide

This decision tree helps patients and clinicians determine if Xyrem (sodium oxybate) will be covered by Humana Medicare Advantage or Part D plans in Pennsylvania. Work through each section in order—don't skip ahead to appeals if you haven't confirmed basic eligibility first.

What you'll need handy: Insurance card, recent clinic notes, sleep study results, and a list of medications you've tried for narcolepsy or excessive daytime sleepiness.

Eligibility Triage: Do You Qualify?

Step 1: Diagnosis Confirmation

Check YES if you have:

  • ✅ Confirmed diagnosis of narcolepsy with cataplexy (ICD-10: G47.411)
  • ✅ Sleep study showing mean sleep latency ≤8 minutes on MSLT
  • ✅ Evidence of ≥2 sleep-onset REM periods (SOREMPs)
  • ✅ Documented cataplexy episodes (sudden muscle weakness triggered by emotions)

Alternative pathway: CSF hypocretin deficiency testing can substitute for sleep studies in some cases.

Step 2: Prior Therapy Documentation

Humana typically requires evidence you've tried:

  • Modafinil or armodafinil (first-line stimulants)
  • Traditional stimulants (if appropriate)
  • Antidepressants for cataplexy management
  • Documentation of failure, intolerance, or contraindications

Step 3: REMS Program Eligibility

Both prescriber and patient must:

  • Complete REMS enrollment forms
  • Acknowledge counseling on abuse risks
  • Agree to single-pharmacy dispensing through certified network

If you answered YES to all three steps: You're likely eligible. Continue to the document checklist.

If you answered YES to steps 1-2 but NO to step 3: You're possibly eligible but need REMS enrollment first.

If you answered NO to step 1 or 2: You're not yet eligible. See alternatives section.

If "Possibly Eligible": Tests to Request

Missing Diagnosis Documentation

Request from your sleep specialist:

  • Complete sleep study interpretation letter
  • Formal narcolepsy diagnosis statement
  • Cataplexy episode documentation with specific examples

Missing Prior Therapy Records

Gather from previous providers:

  • Medication trial summaries
  • Reasons for discontinuation
  • Dosing and duration details

Timeline to re-apply: Once documentation is complete, typically 2-4 weeks for records gathering.

If "Not Yet": Alternatives to Discuss

First-Line Therapies to Try

Before Xyrem approval, Humana typically requires trials of:

  • Modafinil (Provigil): 200-400mg daily
  • Armodafinil (Nuvigil): 150-250mg daily
  • Solriamfetol (Sunosi): 75-150mg daily

Preparing for Exception Requests

If standard therapies are contraindicated, your prescriber can request a formulary exception by documenting:

  • Specific medical reasons why alternatives won't work
  • Safety concerns with first-line options
  • Urgency of treatment need

Exception timeline: Humana must decide within 72 hours (24 hours if expedited).

If Denied: Appeal Path Chooser

Level 1: Internal Appeal with Humana

Who can file: Patient, prescriber, or authorized representative Deadline: 60 days from denial letter Timeline: 7 days for standard appeals, 72 hours for expedited How to file:

Level 2: Independent Review Entity (IRE)

When to use: If Level 1 appeal is denied Timeline: Must request within 60 days of Level 1 denial Process: Medicare assigns independent medical reviewers

Level 3: Pennsylvania External Review

Pennsylvania's new external review program, launched in 2024, offers an additional pathway for residents. Success rate: Approximately 50% of appeals are overturned.

Eligibility: Must complete Humana's internal appeals first Deadline: 4 months from final denial How to file: pa.gov external review portal (verify current link) Timeline: 45 days for standard review, 72 hours for expedited

From our advocates: We've seen patients succeed by focusing on the clinical necessity documentation rather than just fighting the denial reason. One patient's neurologist included a detailed letter explaining how Xyrem's unique mechanism was essential for both cataplexy and sleep consolidation—something other medications couldn't address. The appeal was approved at Level 1.
