From Our Advocates
We've seen Pennsylvania patients successfully overturn Gamifant denials by focusing on three key areas: comprehensive HLH diagnostic documentation, detailed prior therapy failure records, and specialist support letters. The state's new external review program has been particularly effective for rare disease medications when internal appeals don't succeed. This represents a composite of successful strategies, not guaranteed outcomes.
