What Affects Xyrem Approval Timing

Several factors determine how quickly UnitedHealthcare will approve Xyrem in North Carolina:

Plan Type Variations:

  • Commercial plans: Standard 24 hours to 15 calendar days
  • Medicare Advantage: Often faster due to federal oversight, typically 24-72 hours
  • Self-funded employer plans: May follow different timelines; verify with HR

Documentation Completeness:

  • Complete submissions with all required documents: 1-3 business days
  • Incomplete submissions requiring additional information: 7-15 days
  • Missing REMS enrollment: Automatic delay until completed

Submission Method:

  • Electronic submission via UnitedHealthcare provider portal: Fastest (24 hours to 3 days)
  • Fax submissions: 3-7 days
  • Mail submissions: 7-15 days
Note: UnitedHealthcare's OptumRx has introduced automated prior authorization for select medications, with median approval times of 29 seconds for eligible drugs, though Xyrem is not currently in this fast-track program.

    • Modafinil or armodafinil (dose, duration, reason for discontinuation)

If Your PA is Denied: Appeals Timeline

UnitedHealthcare Internal Appeals

Level 1 Appeal:

  • Deadline: 180 days from denial notice
  • Timeline: 15-30 days for standard review, 72 hours for expedited
  • How to submit: UnitedHealthcare member portal, fax, or mail per denial letter
  • Required: Copy of denial letter, medical records, prescriber letter

Level 2 Appeal (if available):

  • Deadline: 60 days from Level 1 denial
  • Timeline: 15-30 days for decision
  • Includes: Independent medical review
From our advocates: "We've seen the strongest appeals include a detailed letter from the sleep specialist explaining why formulary alternatives failed and how Xyrem's unique mechanism addresses both cataplexy and excessive daytime sleepiness. Including peer-reviewed studies supporting off-label uses can also strengthen the case, though this should be a composite of successful strategies rather than guaranteed outcomes."
