Illinois Statutes Chapter 215. Insurance § 5/356z.23. Coverage for opioid antagonists

(a) An individual or group policy of accident and health insurance amended, delivered, issued, or renewed in this State after the effective date of this amendatory Act of the 99th General Assembly that provides coverage for prescription drugs must provide coverage for at least one opioid antagonist, including the medication product, administration devices, and any pharmacy administration fees related to the dispensing of the opioid antagonist. This coverage must include refills for expired or utilized opioid antagonists.

(a-5) Notwithstanding subsection (a), no individual or group policy of accident and health insurance amended, delivered, issued, or renewed after January 1, 2024 that provides coverage for naloxone hydrochloride shall impose a copayment on the coverage provided, except that this subsection does not apply to coverage of naloxone hydrochloride to the extent such coverage would disqualify a high-deductible health plan from eligibility for a health savings account under Section 223 of the Internal Revenue Code.  1

(b) As used in this Section, “opioid antagonist” means a drug that binds to opioid receptors and blocks or inhibits the effect of opioids acting on those receptors, including, but not limited to, naloxone hydrochloride or any other similarly acting drug approved by the U.S. Food and Drug Administration.
