Coverage Basics: Is Firazyr Covered by Aetna CVS Health?

The short answer: Not routinely. Firazyr (icatibant) appears on Aetna's 2024 exclusion drug lists for both commercial and Medicare plans. This means:

  • Your plan won't cover Firazyr automatically
  • You'll need a formulary exception to get any coverage
  • Even with approval, you may face high specialty-tier costs
  • Generic icatibant or Sajazir may be preferred alternatives

Calling Aetna About Your Denial: "Hello, I'm calling about a prior authorization denial for Firazyr. My member ID is [ID number]. I have hereditary angioedema confirmed by lab testing, and my specialist believes Firazyr is medically necessary. Can you tell me specifically why this was denied and what additional information you need for reconsideration?"
