Find a covered prescription drug
A formulary, or drug list, is a list of prescription drugs that are covered by those plans that use the formulary. Drugs in a formulary are grouped into tiers based on cost-sharing ranging from low-cost drugs (mostly generic drugs) to high-cost specialty drugs. The amount you pay will depend on if the drug is included in the formulary and its tier. You can search for a drug to find out if it’s covered, its tier, and if prior authorization or other considerations may be applicable.
