Each tier costs a different amount. Generally, a drug in a lower tier will cost you less than a drug in a higher tier. Example of a drug plan’s tiers • Tier 1—Most generic prescription drugs. Lowest copayment. • Tier 2—Preferred, brand-name prescription drugs. Medium copayment. • Tier 3—Non-preferred, brand-name prescription drugs. Higher copayment.
