The Prescription Drug Benefit

You and your eligible family members are automatically enrolled in a prescription drug plan managed by Express Scripts (ESI) when you sign up for MIT health coverage. The benefit provides a variety of cost savings for eligible prescription drug expenses when they are prescribed by a plan doctor. You can obtain your medications by mail or at retail pharmacies that belong to your health plan's network.

  • When you use an ESI network pharmacy, you can purchase up to a 30-day supply of your medications.
  • When you order through the mail, you can order up to a 90-day supply of your medications.

How it Works

If you are eligible for the Prescription Drug Benefit, Express Scripts (ESI) will send you an ESI ID card automatically. The amount you save depends on

  • how you fill your prescription—by mail or through an ESI network retail pharmacy
  • which tier of drug you purchase
    • Tier 1 drugs—Generic
      Medications that have exactly the same active ingredients as their brand-name counterparts. Your costs will be lowest when you choose Tier 1 drugs.
    • Tier 2 drugs—Preferred brand
      Brand-name medications that are on a list of preferred drugs (also referred to as the Preferred Formulary List available below) that have been approved by a panel of doctors and pharmacists as safe, effective, and less expensive than other alternatives. You will pay more for Tier 2 drugs than Tier 1 drugs.
    • Tier 3 drugs—Non-preferred brand
      Brand-name medications that have not been identified as an effective, lower cost medication on the formulary list. Your costs will be highest when you choose Tier 3 drugs.
