(215 ILCS 5/356z.15)
    Sec. 356z.15. Habilitative services for children.
    (a) As used in this Section, "habilitative services" means occupational therapy, physical therapy, speech therapy, and other services prescribed by the insured's treating physician pursuant to a treatment plan to enhance the ability of a child to function with a congenital, genetic, or early acquired disorder. A congenital or genetic disorder includes, but is not limited to, hereditary disorders. An early acquired disorder refers to a disorder resulting from illness, trauma, injury, or some other event or condition suffered by a child prior to that child developing functional life skills such as, but not limited to, walking, talking, or self-help skills. Congenital, genetic, and early acquired disorders may include, but are not limited to, autism or an autism spectrum disorder, cerebral palsy, and other disorders resulting from early childhood illness, trauma, or injury.
    (b) A group or individual policy of accident and health insurance or managed care plan amended, delivered, issued, or renewed after the effective date of this amendatory Act of the 95th General Assembly must provide coverage for habilitative services for children under 19 years of age with a congenital, genetic, or early acquired disorder so long as all of the following conditions are met:
        (1) A physician licensed to practice medicine in all
    
its branches has diagnosed the child's congenital, genetic, or early acquired disorder.
        (2) The treatment is administered by a licensed
    
speech-language pathologist, licensed audiologist, licensed occupational therapist, licensed physical therapist, licensed physician, licensed nurse, licensed optometrist, licensed nutritionist, licensed social worker, or licensed psychologist upon the referral of a physician licensed to practice medicine in all its branches.
        (3) The initial or continued treatment must be
    
medically necessary and therapeutic and not experimental or investigational.
    (c) The coverage required by this Section shall be subject to other general exclusions and limitations of the policy, including coordination of benefits, participating provider requirements, restrictions on services provided by family or household members, utilization review of health care services, including review of medical necessity, case management, experimental, and investigational treatments, and other managed care provisions.
    (d) Coverage under this Section does not apply to those services that are solely educational in nature or otherwise paid under State or federal law for purely educational services. Nothing in this subsection (d) relieves an insurer or similar third party from an otherwise valid obligation to provide or to pay for services provided to a child with a disability.
    (e) Coverage under this Section for children under age 19 shall not apply to treatment of mental or emotional disorders or illnesses as covered under Section 370 of this Code as well as any other benefit based upon a specific diagnosis that may be otherwise required by law.
    (f) The provisions of this Section do not apply to short-term travel, accident-only, limited, or specific disease policies.
    (g) Any denial of care for habilitative services shall be subject to appeal and external independent review procedures as provided by Section 45 of the Managed Care Reform and Patient Rights Act.
    (h) Upon request of the reimbursing insurer, the provider under whose supervision the habilitative services are being provided shall furnish medical records, clinical notes, or other necessary data to allow the insurer to substantiate that initial or continued medical treatment is medically necessary and that the patient's condition is clinically improving. When the treating provider anticipates that continued treatment is or will be required to permit the patient to achieve demonstrable progress, the insurer may request that the provider furnish a treatment plan consisting of diagnosis, proposed treatment by type, frequency, anticipated duration of treatment, the anticipated goals of treatment, and how frequently the treatment plan will be updated.
    (i) 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.
    (j) An insurer may not deny or refuse to provide otherwise covered services under a group or individual policy of accident and health insurance or a managed care plan solely because of the location wherein the clinically appropriate services are provided.
