§ 155.37. Drug formulary; notice.
(a) Insurance companies that transact the kinds of insurance authorized under Class 1(b) or Class 2(a) of Section 4 of this Code and provide coverage for prescription drugs through the use of a drug formulary must notify insureds of any change in the formulary. A company may comply with this Section by posting changes in the formulary on its website.
(b) No later than October 1, 2025, insurance companies that use a drug formulary shall post the formulary on their websites in a manner that is searchable and accessible to the general public without requiring an individual to create any account. This formulary shall adhere to a template developed by the Department by March 31, 2025, which shall take into consideration existing requirements for reporting of information established by the federal Centers for Medicare and Medicaid Services as well as display of cost-sharing information. This template and all formularies also shall do all the following:
(1) include information on cost-sharing tiers and utilization controls, such as prior authorization, for each covered drug;
(2) indicate any drugs on the formulary that are preferred over other drugs on the formulary;
(3) include information to educate insureds about the differences between drugs administered or provided under a policy's medical benefit and drugs covered under a drug benefit and how to obtain coverage information about drugs that are not covered under the drug benefit;
(4) include information to educate insureds that policies that provide drug benefits are required to have a method for enrollees to obtain drugs not listed in the formulary if they are deemed medically necessary by a clinician under Section 45.1 of the Managed Care Reform and Patient Rights Act;
(5) include information on which medications are covered, including both generic and brand name; and
(6) include information on what tier of the plan's drug formulary each medication is in.
(c) No formulary may establish a step therapy requirement as prohibited by Section 87 of the Managed Care Reform and Patient Rights Act.
