From our advocates: "We've seen the strongest Filsuvez approvals when families work closely with specialized EB centers to document comprehensive treatment attempts. The key is showing that standard wound care hasn't provided adequate healing, not just that it was tried. One family's detailed wound diary showing persistent infections despite multiple dressing types helped overturn an initial denial within 30 days."
