What Affects Xyrem Approval Timing

Several factors determine how quickly UnitedHealthcare processes your Xyrem prior authorization in Illinois:

Documentation Completeness is the biggest factor. Complete submissions with all required elements can receive automated approval in as little as 29 seconds. Missing documentation triggers manual review, extending timelines to 15 days.

REMS Enrollment Status creates a hard stop. Both prescriber and patient must be enrolled in the Xyrem REMS program before any PA can be processed. This typically takes 1-3 business days if completed electronically.

Step Therapy Requirements add complexity. UnitedHealthcare requires documented trials of modafinil and/or armodafinil unless contraindicated. Incomplete medication history documentation will delay or deny approval.

Clinical Urgency can accelerate timelines. Expedited reviews for urgent medical need receive decisions within 24-72 hours when properly documented by your physician.

Note: UnitedHealthcare's OptumRx processes approximately 90% of complete PA requests within the standard 72-hour window, but complex cases requiring clinical review can take the full 15 days.

Pre-Submission Preparation (0-2 Days)

Essential Checklist

Before submitting your PA request, gather these required documents:

REMS Program Verification

  • Confirm both patient and prescriber enrollment at XywavXyremREMS.com
  • Print enrollment confirmation for your records

Clinical Documentation

  • Sleep study reports (polysomnography and MSLT)
  • Narcolepsy diagnosis with ICD-10 codes (G47.411 with cataplexy, G47.419 without)
  • Complete medication history showing modafinil/armodafinil trials and outcomes
  • Current symptom documentation and functional impact

Insurance Information

  • UnitedHealthcare member ID and group number
  • Current formulary status verification
  • Prior authorization form (available through UHC Provider Portal)

Documentation Quality Standards

Your medical necessity letter should include:

  • Specific diagnosis with supporting sleep study data
  • Detailed prior treatment history (medications, doses, duration, reasons for discontinuation)
  • Clinical rationale for Xyrem versus alternatives
  • Expected treatment goals and monitoring plan

Submission to Initial Review (1-5 Days)

Illinois State Requirements

Illinois law requires UnitedHealthcare to acknowledge PA requests within 24 hours and provide decisions within 15 business days for standard requests. Expedited requests must be decided within 24 hours of receiving complete information.

What Reviewers Check First

UnitedHealthcare's initial review focuses on:

  1. REMS Compliance: Verified enrollment for both parties
  2. Step Therapy: Evidence of modafinil/armodafinil failure or contraindication
  3. Diagnosis Confirmation: Sleep study results supporting narcolepsy diagnosis
  4. Clinical Necessity: Symptom severity and functional impact documentation

Submission Methods

Fastest Option: UnitedHealthcare Provider Portal with document upload Alternative: Fax to OptumRx at 1-844-403-1027 Urgent Cases: Call 1-800-711-4555 for expedited processing

Additional Information Requests (1-7 Days)

When UnitedHealthcare requests additional information, you typically have 14 days to respond. Common requests include:

  • More detailed sleep study interpretation
  • Additional medication trial documentation
  • Updated clinical notes from specialist
  • Peer-to-peer review with medical director
Tip: Respond to information requests within 48 hours to avoid delays. Incomplete responses restart the review clock.

From our advocates: We've seen cases where patients submitted partial medication histories, thinking "I tried modafinil years ago" was sufficient. The insurer needed specific dates, doses, and documented reasons for discontinuation. Having your sleep specialist prepare a comprehensive treatment timeline upfront prevents these delays.

Time-Saving Tips for Faster Approval

  • Check PA status daily through member portal

Documentation Bundling

Submit these together in initial request:

  • Complete PA form with all sections filled

Direct Specialty Routing

Have your sleep specialist or neurologist submit the PA rather than primary care physician. Specialists familiar with narcolepsy treatment criteria achieve higher approval rates.
