Drugs on a formulary are often organized into different drug "tiers," or groups of different drug types. Your cost depends on which drug tier your drug is in.
For example, a plan may form tiers this way:
- Tier 1 - Generic drugs.
- Tier 2 - Preferred brand-name drugs.
- Tier 3- Non-preferred brand name drugs.
Contact the plan to learn more about its specific tier structure.
