Timeline to Re-apply

  • Lab results: Available within 1-3 business days

FAQ

How long does Blue Cross NC prior authorization take? Standard requests: 15 calendar days. Urgent requests: 72 hours. Submit early in the week for fastest processing.

What if Nucala is non-formulary on my plan? Request a formulary exception with medical necessity documentation. Include specialist support and evidence of inadequate alternatives.

Can I request an expedited appeal? Yes, if delays would seriously jeopardize your health. Both Blue Cross NC and Smart NC offer expedited reviews (72 hours or less).

Does step therapy apply if I failed biologics in another state? Provide documentation of previous biologic trials and outcomes. Blue Cross NC should accept out-of-state specialist records and pharmacy history.

What counts as adequate inhaled therapy documentation? High-dose ICS (≥500 mcg fluticasone equivalent) plus LABA/LAMA for ≥3 months with documented poor control or systemic steroid dependence.

How successful are Smart NC appeals for specialty drugs? While exact statistics aren't published, advocacy reports indicate high success rates when comprehensive clinical evidence and specialist support are included.

Can my doctor request a peer-to-peer review? Yes, providers can request to speak directly with Blue Cross NC medical directors. This often resolves denials faster than formal appeals.

What if I'm switching from another biologic? Document the reason for switching (inadequate response, side effects, etc.) and provide evidence that Nucala is the appropriate next step.

From our advocates: We've seen many North Carolina patients successfully obtain Nucala coverage after initial denials by working closely with their specialists to document eosinophil levels and prior therapy failures, then leveraging Smart NC's external review process when internal appeals weren't successful. The key is thorough documentation and persistence through the appeals process.
