Formulary (aka Drug list)

A formulary lists generic and brand-name prescription medications covered by your insurance plan. Prescription medications are grouped into tiers, and your drug’s tier determines your portion of the cost. Tier 1 usually covers generic medications, making this the lowest-cost tier. Higher tiers cover preferred and non-preferred brand-name medications at a higher cost. If your medication is not included on a formulary tier, it is not covered by a plan.
