What is a “Formulary”?
A formulary is a listing of all the medications your insurance company covers, including the cost of the co-pay associated with each particular medication. Most formularies are “tiered”, meaning that while a particular medication may be covered under your policy, it may belong in a higher tier, which typically translates into a higher co-pay for you. Tier structures tend to be highly variable and dependent on each individual’s insurance policy. If you bring your formulary with you to your appointment, your physician may be able to help you choose the most appropriate medication on the lowest tier (i.e., the least expensive co-pay).
