215 ILCS 125/4-5
No contract or evidence of coverage issued by a health maintenance organization which provides coverage for health care services shall deny reimbursement for an otherwise covered expense incurred for any organ transplantation procedure solely on the basis that such procedure is deemed experimental or investigational unless supported by the determination of the Office of Health Care Technology Assessment within the Agency for Health Care Policy and Research within the federal Department of Health and Human Services that such procedure is either experimental or investigational or that there is insufficient data or experience to determine whether an organ transplantation procedure is clinically acceptable. If a health maintenance organization has made written request, or had one made on its behalf by a national organization, for determination by the Office of Health Care Technology Assessment within the Agency for Health Care Policy and Research within the federal Department of Health and Human Services as to whether a specific organ transplantation procedure is clinically acceptable and said organization fails to respond to such a request within a period of 90 days, the failure to act may be deemed a determination that the procedure is deemed to be experimental or investigational.
