Some plans group their formulary, or Drug List, into tiers. Tiers help determine the amount you’ll pay for your prescription. Typically, drugs in lower tiers cost less than those in higher tiers.
Tier 1: Preferred generics usually include more common, lower-cost, generic prescription drugs.
Tier 2: Generics usually include higher-cost generic prescription drugs and some lower-cost brand prescription drugs.
Tier 3: Preferred brands are brand-name drugs that don't have a generic equivalent.
Tier 4: Non-preferred drug is a higher-priced brand and generic drugs with no preferred cost share.
Tier 5: Specialty tier is the most expensive drugs, usually used to treat complex conditions such as cancer, multiple sclerosis or rheumatoid arthritis.
