Prescription drug benefits are included as part of your health care package when you are enrolled in a University health plan. Express Scripts is the manager of Washington University's prescription drug benefit program. 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.
