Answer Box: Getting Mepsevii Covered by UnitedHealthcare in Pennsylvania

Yes, you can get Mepsevii (vestronidase alfa-vjbk) covered by UnitedHealthcare in Pennsylvania if you have confirmed MPS VII diagnosis. UnitedHealthcare requires prior authorization but does NOT require step therapy since Mepsevii is the only FDA-approved treatment for MPS VII. First step today: Contact your geneticist or metabolic specialist to gather diagnostic documentation (enzyme assay results, genetic testing, current weight). Submit PA through OptumRx provider portal with complete specialist documentation. If denied, Pennsylvania's new external review process has overturned 50% of specialty drug denials in 2024.
