Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

    (a) The Director shall prescribe by rule, after consultation with providers of health care or treatment, insurers, hospital, medical, and dental service corporations, and other prepayment organizations, insurance claim and billing forms that the Director determines will provide for uniformity and simplicity in insurance claims handling. The claim forms shall include, but need not be limited to, information regarding the medical diagnosis, treatment, and prognosis of the patient, together with the details of charges incident to the providing of care, treatment, or services, sufficient for the purpose of meeting the proof requirements of an insurance policy or a hospital, medical, or dental service contract.

application of any other policy limitation or exclusion set forth in the insured's policy, along with an explanation thereof.
        (4) The total dollar amount paid.
        (5) The total dollar amount remaining unpaid.
    (d) The Director may issue an order directing an accident and health insurer to comply with subsection (c).
    (e) An accident and health insurer does not violate subsection (c) by using a document that the accident and health insurer is required to use by the federal government or the State.
    (f) The adoption of uniform claim forms and uniform billing forms by the Director under this Section does not preclude an insurer, hospital, medical, or dental service corporation, or other prepayment organization from obtaining any necessary additional information regarding a claim from the claimant, provider of health care or treatment, or certifier of coverage, as may be required.
    (g) On and after January 1, 1996 when billing insurers or otherwise filing insurance claims with insurers subject to this Section, providers of health care or treatment, medical services, dental services, pharmaceutical services, or medical equipment must use the uniform claim and billing forms adopted by the Director under this Section.
