Opfolda (Miglustat) Approval with UnitedHealthcare in Washington: Complete Guide to Coverage, Appeals, and Patient Support

Quick Answer: Getting Opfolda Covered by UnitedHealthcare in Washington

Opfolda (miglustat) requires prior authorization from UnitedHealthcare and must be prescribed with Pombiliti for late-onset Pompe disease in adults ≥40 kg who aren't improving on current enzyme replacement therapy. Start by having your provider submit a PA request through OptumRx with documentation of your LOPD diagnosis, current ERT regimen, and evidence of inadequate clinical response. If denied, you have internal appeals (up to 180 days) and external review through Washington's Independent Review Organization (within 4 months).

Coverage Basics

Is Opfolda Covered by UnitedHealthcare?

Yes, but with strict requirements. Opfolda is covered under UnitedHealthcare's specialty pharmacy benefit when prescribed correctly as combination therapy. Key point: Opfolda is never covered as monotherapy—it must be prescribed with Pombiliti (cipaglucosidase alfa).
