Current Provider: Express Scripts


Regardless of whether you are enrolled in a United HealthCare (UHC) or Anthem Blue Cross Blue Shield health plan, your prescription drug benefits are administered by Express Scripts.

With the exception of the High Deductible Health Plan (HDHP), drugs are categorized by tier. Tier One is primarily generic drugs; Tier Two is primarily preferred brand name drugs; and Tier Three is primarily non-preferred brand name drugs. With the HDHP, you must pay the full negotiated cost of the drug until your HDHP deductible is satisfied; then, you pay a 20% co-insurance.
