What Drives Tysabri Costs with UnitedHealthcare

Understanding your UnitedHealthcare plan's benefit design helps predict and manage Tysabri costs. Here's what influences your out-of-pocket expenses:

Specialty Tier Placement

Tysabri typically sits on UnitedHealthcare's specialty tier, which carries the highest cost-sharing. For 2025, Medicare Part D members benefit from a new $2,000 annual out-of-pocket maximum, but commercial plan members face variable cost-sharing without this federal cap.

Prior Authorization Requirements

UnitedHealthcare requires prior authorization for Tysabri through OptumRx. Recent policy changes in 2025 have increased utilization management for specialty medications, including multiple sclerosis treatments.

Note: OptumRx announced in March 2025 that they're eliminating reauthorizations for approximately 80 drugs, potentially reducing some administrative burden for established patients.

Specialty Pharmacy Network

UnitedHealthcare mandates that outpatient providers obtain Tysabri from designated specialty pharmacies including AllianceRx Walgreens Pharmacy, Amber Specialty Pharmacy, Option Care Health, and Optum Specialty Pharmacy, unless an exception is granted.

Annual Renewal Planning

What Changes Each Year

  • Formulary placement and tier assignments
  • Prior authorization requirements

Renewal Checklist

  • Review new formulary documents in October-November
