About Counterforce Health: Counterforce Health helps patients, clinicians, and specialty pharmacies turn insurance denials into successful appeals. Our platform analyzes denial letters and plan policies to create targeted, evidence-backed appeals that meet payer-specific requirements. For complex cases like Opfolda approvals, we identify the exact denial basis and draft point-by-point rebuttals using FDA labeling, peer-reviewed studies, and specialty guidelines.

From Our Advocates: We've seen Opfolda denials successfully overturned when appeals include specific documentation of ERT failure with dates and clinical markers, plus clear explanation of the combination therapy requirement. The key is addressing the payer's exact denial reason rather than submitting generic medical necessity letters. Success rates improve significantly when appeals quote the plan's own policy criteria verbatim.
