215 ILCS 5/356g.5-1
A group or individual policy of accident and health insurance or managed care plan that is amended, delivered, issued, or renewed after the effective date of this amendatory Act of the 95th General Assembly must provide coverage for all medically necessary pain medication and pain therapy related to the treatment of breast cancer on the same terms and conditions that are generally applicable to coverage for other conditions. For purposes of this Section, "pain therapy" means pain therapy that is medically based and includes reasonably defined goals, including, but not limited to, stabilizing or reducing pain, with periodic evaluations of the efficacy of the pain therapy against these goals. The provisions of this Section do not apply to short-term travel, accident-only, limited, or specified-disease policies, or to policies or contracts designed for issuance to persons eligible for coverage under Title XVIII of the Social Security Act, known as Medicare, or any other similar coverage under State or federal governmental plans.
Rulemaking authority to implement this amendatory Act of the 95th General Assembly, if any, is conditioned on the rules being adopted in accordance with all provisions of the Illinois Administrative Procedure Act and all rules and procedures of the Joint Committee on Administrative Rules; any purported rule not so adopted, for whatever reason, is unauthorized.
