Illinois Statutes Chapter 215. Insurance § 161/10. Noncovered services

(a) No vision care organization that issues, delivers, amends, or renews a vision care plan on or after the effective date of this Act shall issue a contract that requires an eye care provider, as a condition of participation in the vision care plan, to provide services or materials to an enrollee at a fee set by the vision care plan unless the services or materials are covered services or covered materials under the vision care plan. De minimis reimbursements shall not qualify a service or material as a covered service or a covered material under this Act.

(b) An eye care provider who chooses not to accept as payment an amount set by a vision care plan for services or materials that are not covered services or covered materials shall post, in a conspicuous place, a notice stating the following: “IMPORTANT: This eye care provider does not accept the fee schedule set by your insurer for vision care services and vision care materials that are not covered benefits under your plan and instead charges his or her normal fee for those services and materials. This eye care provider will provide you with an estimated cost for each noncovered service or noncovered material upon your request.”
