Costs & Patient Assistance

Financial Support Options

Kuvan costs approximately $30,000-$300,000+ annually depending on weight and dosing. Financial assistance options include:

Manufacturer Support:

  • BioMarin RareConnections™ - Patient support program
  • Copay assistance for eligible commercially-insured patients
  • Free drug programs for qualifying uninsured patients

Foundation Grants:

  • National PKU Alliance assistance programs
  • HealthWell Foundation grants for rare diseases
  • Patient Access Network Foundation

State Programs: Illinois residents may qualify for additional support through state rare disease programs.

From our advocates: We've seen families successfully secure Kuvan coverage after initial denials by working closely with their metabolic specialist to document clear biochemical response data. The key is having baseline and post-trial Phe levels that show objective improvement, not just clinical impressions.

FAQ

How long does BCBS Illinois prior authorization take for Kuvan? Electronic submissions via CoverMyMeds typically receive responses within 2-5 business days. Fax submissions may take 7-10 business days.

What if Kuvan is non-formulary on my plan? Request a formulary exception by demonstrating medical necessity. Include documentation that standard PKU treatments (diet alone) are insufficient.

Can I request expedited review if my child needs Kuvan urgently? Yes, if delays would seriously jeopardize health or function, request expedited internal appeal (24-hour response) and expedited external review if needed.

Does step therapy apply to Kuvan in Illinois? Most BCBS policies require trial of dietary management first, but don't typically require other drug trials since Kuvan is often first-line pharmacotherapy for BH4-responsive PKU.

What if I've been using Kuvan successfully in another state? Document your response history and current Phe levels. BCBS Illinois should honor established medical necessity, but may require their specific PA forms.

How often do I need reauthorization? Typically annually, with updated labs showing continued response (Phe levels <600 µmol/L or ≥20% reduction maintained).
