215 ILCS 5/356z.48: Colonoscopy coverage.

(a) A group policy of accident and health insurance that is amended, delivered, issued, or renewed on or after January 1, 2022 shall provide coverage for a colonoscopy that is a follow-up exam based on an initial screen where the colonoscopy was determined to be medically necessary by a physician licensed to practice medicine in all its branches, an advanced practice registered nurse, or a physician assistant.

(b) A group or individual policy of accident and health insurance or managed care plan amended, delivered, issued, or renewed on or after January 1, 2026 shall provide coverage for a colonoscopy determined to be medically necessary.

(c) A policy subject to this Section shall not impose a deductible, coinsurance, copayment, or any other cost-sharing requirement on the coverage provided; except that this subsection does not apply to coverage of colonoscopies to the extent such coverage would disqualify a high-deductible health plan from eligibility for a health savings account pursuant to Section 223 of the Internal Revenue Code.
