Answer Box: Getting Fabrazyme Covered by UnitedHealthcare in Washington

UnitedHealthcare requires prior authorization for Fabrazyme (agalsidase beta) in Washington, typically decided within 1-3 business days for standard requests once complete documentation is received. Key requirements include genetic testing confirming Fabry disease, specialist prescription, and clinical evidence of organ involvement. If denied, Washington residents have strong appeal rights including external review through the Office of the Insurance Commissioner.

Fastest path to approval:

  2. Submit PA through UnitedHealthcare Provider Portal with complete clinical documentation
  3. If denied, request peer-to-peer review within 24 hours, then file internal appeal if needed

Coverage Requirements at a Glance

Requirement What It Means Where to Find It Timeline
Prior Authorization Required for all Fabrazyme prescriptions UHC Provider Portal 1-3 business days
Genetic Testing Pathogenic GLA mutation or enzyme deficiency Specialist clinic notes Before PA submission
Specialist Prescription Geneticist, nephrologist, cardiologist, or neurologist Provider credentials verification At time of prescription

What Affects Approval Timing

Several factors influence how quickly UnitedHealthcare processes Fabrazyme prior authorization requests in Washington:

Benefit Type and Plan Structure

  • Commercial plans using OptumRx: Pharmacy benefit PA, typically faster processing
  • UnitedHealthcare Community Plan (Apple Health): Medical benefit PA, may require additional review
  • Medicare Advantage: Subject to federal timelines plus any state protections

Documentation Completeness The most significant factor affecting approval speed is having complete clinical documentation upfront. UnitedHealthcare's PA requirements for enzyme replacement therapies like Fabrazyme are specific and comprehensive.

Clinical Complexity Cases requiring medical director review (borderline criteria, off-label use, or complex medical history) take longer than straightforward approvals meeting standard criteria.

Pre-Submission Preparation (0-2 Days)

Essential Documentation Checklist

Before submitting your Fabrazyme PA request, gather these required documents:

  • GLA gene test showing pathogenic or likely pathogenic variant
  • If genetic testing unavailable: enzyme activity test showing deficient α-galactosidase A activity (<5% of normal)

✓ Specialist Documentation

  • Recent consultation note from geneticist, nephrologist, cardiologist, or neurologist
  • Clear documentation of Fabry disease diagnosis (ICD-10 E75.21)
  • Clinical manifestations and organ involvement

Initial Review Process

  2. Clinical Review (Days 1-3): Pharmacist or medical director reviews against Fabrazyme-specific criteria
  3. Decision Communication: Approval or denial notice sent to provider and member

What Reviewers Check First

  • Valid Fabry disease diagnosis with genetic or biochemical confirmation
  • Specialist prescriber credentials and recent evaluation
