Coverage Basics

Is Evrysdi Covered by Humana?

Evrysdi (risdiplam) is covered under Humana Medicare Part D and Medicare Advantage plans, but requires prior authorization due to its specialty status and high cost (approximately $340,000 annually). The medication is typically placed on a high-tier formulary requiring documentation of medical necessity.

Which Humana Plans Cover Evrysdi?

  • Medicare Part D: All Humana Part D plans include Evrysdi on formulary with PA
  • Medicare Advantage: Coverage varies by specific plan; check your formulary at Humana's drug list tool
