From Our Advocates

We've seen many Washington families successfully overturn initial Vyondys 53 denials by ensuring their genetic testing report explicitly states "amenable to exon 53 skipping." One family's appeal was approved within two weeks after their neurologist submitted a clarifying letter explaining how their child's specific deletion pattern (exons 48-52) qualified for exon 53 skipping therapy. The key was connecting the genetic findings directly to the FDA indication.

Washington Appeals Process
