Bonnie is trying to understand how a formulary (drug list) works. She's been doing some research and made notes to discuss with you. Which of Bonnie's notes about formularies is NOT accurate? Select the correct answer. Health insurance plans use the terms 'formulary' or 'drug list' to describe the list of prescription drugs that they cover. A formulary includes details about the copayment the consumer pays for each type of covered drug.
