HealthChoice Illinois and the State's BCBS-Dominant Market

HealthChoice Illinois, launched statewide January 1, 2018, delivers Medicaid through three separate programs administered by the Department of Healthcare and Family Services (HFS): HealthChoice Illinois (HCI) for most beneficiaries, YouthCare for special needs children, and the Medicare Medicaid Alignment Initiative (MMAI) for dual eligibles, which became statewide in July 2021. Roughly 80 percent of Illinois Medicaid beneficiaries receive care through managed care organizations rather than traditional fee-for-service.

On the commercial side, Blue Cross Blue Shield of Illinois (BCBSIL), a subsidiary of Health Care Service Corporation, is by far the dominant carrier, covering more than 8.9 million members across all 102 counties and reaching over 96 percent of Illinois physicians and hospitals. In the Chicago metro area specifically, BCBSIL's share has run as high as 68 percent, making it the default network for most Illinois employers and practices.
