(a) A group or individual policy of accident and health insurance or managed care plan amended, delivered, issued, or renewed after December 12, 2008 (the effective date of Public Act 95-1005) must provide individuals under 21 years of age coverage for the diagnosis of autism spectrum disorders and for the treatment of autism spectrum disorders to the extent that the diagnosis and treatment of autism spectrum disorders are not already covered by the policy of accident and health insurance or managed care plan.
     (b) Coverage provided under this Section shall be subject to a maximum benefit of $36,000 per year, but shall not be subject to any limits on the number of visits to a service provider. After December 30, 2009, the Director of the Division of Insurance shall, on an annual basis, adjust the maximum benefit for inflation using the Medical Care Component of the United States Department of Labor Consumer Price Index for All Urban Consumers. Payments made by an insurer on behalf of a covered individual for any care, treatment, intervention, service, or item, the provision of which was for the treatment of a health condition not diagnosed as an autism spectrum disorder, shall not be applied toward any maximum benefit established under this subsection.
     (c) Coverage under this Section shall be subject to copayment, deductible, and coinsurance provisions of a policy of accident and health insurance or managed care plan to the extent that other medical services covered by the policy of accident and health insurance or managed care plan are subject to these provisions.
     (d) This Section shall not be construed as limiting benefits that are otherwise available to an individual under a policy of accident and health insurance or managed care plan and benefits provided under this Section may not be subject to dollar limits, deductibles, copayments, or coinsurance provisions that are less favorable to the insured than the dollar limits, deductibles, or coinsurance provisions that apply to physical illness generally.
     (e) An insurer may not deny or refuse to provide otherwise covered services, or refuse to renew, refuse to reissue, or otherwise terminate or restrict coverage under an individual contract to provide services to an individual because the individual or their dependent is diagnosed with an autism spectrum disorder or due to the individual utilizing benefits in this Section.
     (e-5) 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.
     (f) Upon request of the reimbursing insurer, a provider of treatment for autism spectrum disorders shall furnish medical records, clinical notes, or other necessary data that substantiate that initial or continued medical treatment is medically necessary and is resulting in improved clinical status. When treatment is anticipated to require continued services to achieve demonstrable progress, the insurer may request a treatment plan consisting of diagnosis, proposed treatment by type, frequency, anticipated duration of treatment, the anticipated outcomes stated as goals, and the frequency by which the treatment plan will be updated.
     (g) When making a determination of medical necessity for a treatment modality for autism spectrum disorders, an insurer must make the determination in a manner that is consistent with the manner used to make that determination with respect to other diseases or illnesses covered under the policy, including an appeals process. During the appeals process, any challenge to medical necessity must be viewed as reasonable only if the review includes a physician with expertise in the most current and effective treatment modalities for autism spectrum disorders.
     (h) Coverage for medically necessary early intervention services must be delivered by certified early intervention specialists, as defined in 89 Ill. Adm. Code 500 and any subsequent amendments thereto.
     (h-5) If an individual has been diagnosed as having an autism spectrum disorder, meeting the diagnostic criteria in place at the time of diagnosis, and treatment is determined medically necessary, then that individual shall remain eligible for coverage under this Section even if subsequent changes to the diagnostic criteria are adopted by the American Psychiatric Association. If no changes to the diagnostic criteria are adopted after April 1, 2012, and before December 31, 2014, then this subsection (h-5) shall be of no further force and effect.
     (h-10) An insurer may not deny or refuse to provide covered services, or refuse to renew, refuse to reissue, or otherwise terminate or restrict coverage under an individual contract, for a person diagnosed with an autism spectrum disorder on the basis that the individual declined an alternative medication or covered service when the individual’s health care provider has determined that such medication or covered service may exacerbate clinical symptomatology and is medically contraindicated for the individual and the individual has requested and received a medical exception as provided for under § 45.1 of the Managed Care Reform and Patient Rights Act. For the purposes of this subsection (h-10), “clinical symptomatology” means any indication of disorder or disease when experienced by an individual as a change from normal function, sensation, or appearance.
     (h-15) If, at any time, the Secretary of the United States Department of Health and Human Services, or its successor agency, promulgates rules or regulations to be published in the Federal Register or publishes a comment in the Federal Register or issues an opinion, guidance, or other action that would require the State, pursuant to any provision of the Patient Protection and Affordable Care Act (Public Law 111-148), including, but not limited to, 42 U.S.C. § 18031(d)(3)(B) or any successor provision, to defray the cost of any coverage outlined in subsection (h-10), then subsection (h-10) is inoperative with respect to all coverage outlined in subsection (h-10) other than that authorized under Section 1902 of the Social Security Act, 42 U.S.C. § 1396a, and the State shall not assume any obligation for the cost of the coverage set forth in subsection (h-10).
