1. Verify Your Plan and Find the Right Forms

Before starting your Kuvan prior authorization, confirm your specific UnitedHealthcare plan type. The process differs slightly between commercial plans, Medicare Advantage, and Medicaid managed care.

Start Here:

  • Log into your member portal or call the number on your insurance card
  • Verify Kuvan's formulary status (it may be excluded and require an exception)
  • Confirm whether your plan uses OptumRx for specialty pharmacy benefits
  • Check if you need to use a specific specialty pharmacy from UnitedHealthcare's network
Tip: UnitedHealthcare formularies change regularly. Generic sapropterin (Javygtor) may have different coverage rules than brand Kuvan, so verify both options.

From Our Advocates: We've seen several North Carolina patients successfully overturn UnitedHealthcare denials for expensive PKU medications through Smart NC's external review process. The key was providing comprehensive documentation of dietary compliance and metabolic specialist support. While outcomes aren't guaranteed, the external review process provides an important safety net when internal appeals fail.
