If "Likely Eligible": Document Checklist

Required Documentation for Prior Authorization

Medical Records Must Include:

  • Fabry disease diagnosis with ICD-10 code E75.21
  • Genetic test report confirming amenable GLA variant
  • Current eGFR lab results (within 3 months)
  • Specialist consultation notes (metabolic, genetic, or nephrology)
  • Documentation that patient is not receiving combination therapy

Submission Process:

  1. Provider submits PA: Call 866-889-8054 or use UnitedHealthcare Provider Portal

If "Possibly Eligible": Tests to Request

Missing Genetic Testing

Request from your specialist:

  • Complete GLA gene sequencing (not just enzyme activity)
  • In vitro amenability assay for identified variants
  • Genetic counseling consultation if family history unclear

Timeline: Genetic testing typically takes 2-4 weeks; plan accordingly for medication needs.

Kidney Function Monitoring

If eGFR 30-45 mL/min/1.73m²:

  • Request nephrology consultation
  • Document stability of kidney function over 3-6 months
  • Consider cardiovascular risk assessment

Reapply when: Updated labs and specialist recommendations are available.

Preparing for Exception Requests

  • ERT access challenges (infusion center availability, work schedule conflicts)
  • Antibody development to current ERT
  • Infusion-related reactions or intolerability
  • Patient preference for oral therapy with clinical justification

If Denied: Appeal Path Chooser

Internal Appeals (First Level)

Timeline: Must file within 180 days of denial notice How to file:

  • Online: UnitedHealthcare member portal
  • Phone: Number on your denial letter
  • Mail: Address provided in denial notice

Required documents:

  • Original denial letter

Peer-to-Peer Review

When to request: Before or during internal appeal process Process: Your doctor discusses case directly with UnitedHealthcare medical director Timeline: Usually scheduled within 3-5 business days

From our advocates: In our experience with Fabry disease appeals, peer-to-peer reviews are often successful when the prescribing specialist can clearly explain why the specific GLA variant makes Galafold the preferred option over enzyme replacement therapy. Having the genetic test report and amenability data readily available during the call significantly improves outcomes.

What if Galafold isn't on my formulary? Galafold requires prior authorization but is typically covered when medical criteria are met. Non-formulary status doesn't prevent coverage with proper documentation.

Can I get an expedited appeal if I'm currently on enzyme replacement? Yes, if switching is urgent due to access issues, adverse reactions, or clinical deterioration. Document the urgency with your specialist.

Does step therapy apply if I've tried ERT outside New York? Previous treatment history from any state counts toward step therapy requirements. Provide complete documentation of prior therapies.

What genetic testing laboratories does UnitedHealthcare accept? UnitedHealthcare typically accepts testing from major commercial labs and academic medical centers. Verify with your plan before testing (confirm with UnitedHealthcare provider services).

How much does Galafold cost with UnitedHealthcare coverage? Cost varies by plan. List price is approximately $30,000+ per month. Check your specific copay through the member portal or contact customer service.

Can I appeal if my variant amenability is uncertain? Yes. Include all available genetic data and request coverage pending additional amenability testing if clinically appropriate.

What if I need Galafold while my appeal is pending? Ask your specialist about manufacturer patient assistance programs or temporary supply options through Amicus Therapeutics.
