About Coverage Navigation Support

Counterforce Health specializes in helping patients navigate complex prior authorization and appeals processes for specialty medications like Hemgenix. Their platform analyzes denial letters and insurance policies to create targeted, evidence-backed appeals that address specific payer requirements. For patients facing denials of expensive gene therapies, professional appeal support can significantly improve approval chances by ensuring all clinical criteria are properly documented and presented.

From Our Advocates: "We've seen Hemgenix approvals succeed when patients work closely with their hemophilia treatment centers to document not just the clinical criteria, but the real-world impact of bleeding episodes on daily life. One case involved compiling three years of emergency room visits and missed work days alongside the required lab values – that comprehensive picture helped demonstrate medical necessity beyond the basic eligibility checklist."
