From our advocates: We've seen Pennsylvania's external review process work particularly well for specialty medications like Palynziq. The independent reviewers often have more expertise in rare diseases than internal insurance reviewers. One key tip: when submitting your additional evidence during the 15-day window, include peer-reviewed studies about Palynziq's efficacy and any relevant PKU treatment guidelines.
