Coverage Overview: Humana's Evrysdi Policy

Humana Medicare Advantage plans in Illinois require prior authorization for Evrysdi (risdiplam), a high-cost specialty medication for spinal muscular atrophy (SMA). The drug typically falls under Humana's Clinical Pharmacy Review (HCPR) process, which applies strict medical necessity criteria before approval.

  • Medicare Advantage Part D: Prior authorization required
  • Commercial plans: Varies by employer group; most require PA
  • Medicaid managed care: Subject to state Medicaid criteria plus Humana's additional requirements

Evrysdi's annual cost can reach approximately $340,000, making it one of the most scrutinized medications in Humana's formulary management system.

Medical Necessity Requirements

Baseline Motor Function Assessment Insurance requires at least one standardized assessment appropriate for the patient's age and motor abilities:
