The Illinois Department may enter into co-operative arrangements with State agencies responsible for administering or supervising the administration of health services and vocational rehabilitation services to the end that there may be maximum utilization of such services in the provision of medical assistance. The Illinois Department may certify managed care community networks, including managed care community networks owned, operated, managed, or governed by State-funded medical schools, as risk-bearing entities eligible to contract with the Illinois Department as Medicaid managed care organizations. The Illinois Department may contract with those managed care community networks to furnish health care services to or arrange those services for individuals participating in programs administered by the Illinois Department. The rates for those provider-sponsored organizations may be determined on a prepaid, capitated basis.
