Replaces everything after the enacting clause. Amends the Medical Assistance Article of the Illinois Public Aid Code. Requires the Department of Healthcare and Family Services to offer children with complex medical needs the choice of enrollment in a coordinated care entity (CCE) to provide services to the children, where available. Provides that this choice shall be in addition to otherwise available health maintenance organizations (HMOs), managed care community networks, and accountable care entities. Provides that children with complex medical needs under 18 years of age are eligible to enroll in the CCE as long as such children continue to maintain eligibility for medical assistance programs or other health benefit programs administered by the Department; and that the Department may choose to extend enrollment to individuals under 21 years of age for initial enrollment. Provides that individuals may also be excluded under specified circumstances. Requires the Department to ensure that: the parents of eligible enrollees who are children with complex medical needs receive notification of their eligibility and an explanation of how to elect the CCE option; and any third party enrollment broker is briefed on the CCE option. Defines "Care Coordination Entity" and "children with complex medical needs". Makes other changes. Effective immediately.
