If I switch plans, how do I make sure the drug I am taking is covered under the new plan?

All Marketplace health insurers must make the formulary or list of covered drugs available to consumers on their websites. Consumers should be able to easily access a health plan’s formulary on an insurer’s website without creating an account or entering a policy number to access the information. In addition, the website link to the formulary should also be included in the Summary of Benefits and Coverage, which provides information on the covered benefits and applicable cost-sharing amounts, and on the Marketplace website. (45 C.F.R. § 147.200; 45 C.F.R. § 156.122).
