Prescription drug tiers defined

Access the Approved Drug List online. When browsing the Approved Drug List, you’ll notice that drugs are listed with a tier level. There are nine total tiers on the Approved Drug List. Different tiers denote different costs and coverage as determined by Priority Health, and the type of tiers available to you for each drug will depend on your plan type.

Here's a breakdown of the meaning of each tier (this information can also be found in the Approved Drug List):

  • tier 1 Medicaid icon

    Tier 1a: ($) The least expensive prescription drugs available to you. This tier includes lowest-cost generic drugs—proven to be as safe as brand-name drugs—and, on some formularies, select brand-name drugs.

    Tier 1b: ($) This tier includes low-cost generic drugs—proven to be as safe as brand-name drugs—and, on some formularies, select brand-name drugs.

  • tier 2 optimized icon

    Tier 2: ($$) Includes preferred and lower cost brand-name drugs, and some higher cost generic drugs. If you must take a brand-name drug, you should work with your provider to choose one that is covered here, and the most affordable.

  • Tier 3 optimized icon

    Tier 3: ($$$) Non-preferred and expensive brand-name drugs, as well as higher-cost generic drugs. These drugs may cost you a significant amount out of pocket so you should ask your provider if a tier 1 or 2 option can be prescribed instead.

  • Tier 4 Medicare icon

    Tier 4: ($$$$) Includes very expensive brand-name and generic drugs, and preferred specialty drugs used to treat complex conditions. Specialty drugs often have high costs and may have special handling or storage requirements. They are usually dispensed by trained personnel at specialty pharmacies. If you need to take a specialty drug, you should work with your provider to choose one that is covered here. These drugs do not typically have a specific copay. Instead, you may pay a percentage of the total cost, up to a maximum amount per prescription.

  • Tier 5 Medicare icon

    Tier 5: ($$$$$) Non-preferred specialty drugs, and the most expensive brand-name and generic drugs are covered here because they offer limited clinical value. Most have a similar lower-cost option offering the same clinical value on tiers 1 through 4. Ask your provider about alternatives. These drugs typically do not have a specific copay. Instead, you may pay a percentage of the total cost, up to a maximum amount per prescription.

  • Tiers 6-8: ($$$$$$) A drug that is covered by your medical plan benefits instead of your prescription plan benefits. Check your plan documents for details.

    Tier 9: ($$$$$$$$) A drug that your prescription plan will not pay for or that is not included on the Approved Drug List. Check your plan documents for details.
