Coverage Basics

Is Nucala Covered by Aetna CVS Health?

Nucala is covered by Aetna CVS Health plans in New York, but it's classified as a non-preferred specialty medication requiring prior authorization. Unlike preferred biologics such as Fasenra (benralizumab), Nucala sits on a higher formulary tier, meaning higher out-of-pocket costs and stricter approval criteria.

From Our Advocates: We've seen multiple Nucala cases overturned on external review when patients provided comprehensive documentation showing severe eosinophilic asthma with documented biologic failures. The key was including peer-reviewed literature supporting mepolizumab's efficacy for their specific phenotype. While outcomes vary, thorough preparation significantly improves success rates.

Annual Renewals

  • Continued Clinical Benefit: Reduced exacerbations, improved asthma control
  • Ongoing Medical Necessity: Still meets FDA indication criteria
  • Treatment Adherence: Continued use of maintenance asthma medications
  • No New Exclusions: Patient doesn't now meet exclusion criteria

Mark your calendar 30 days before your approval expires to ensure uninterrupted coverage.

Once approved, Nucala must be dispensed through CVS Specialty Pharmacy:

  • Automatic Transfer: CVS will contact your local pharmacy to transfer the prescription
  • Delivery Options: Home delivery or pickup at CVS locations
  • Injection Training: CVS provides autoinjector training and support
