The Illinois Health Insurance Marketplace
Illinois transitioned to a state-based marketplace using the federal platform, operating under the name Get Covered Illinois. While enrollment still occurs through HealthCare.gov, the state manages outreach, consumer assistance, and plan oversight at the state level.
This hybrid approach gives Illinois residents:
- Federal platform enrollment: The familiar HealthCare.gov interface for shopping, comparing, and enrolling in plans.
- State-directed outreach: Get Covered Illinois coordinates local navigators, enrollment events, and community-based assistance across the state.
- Plan oversight: The Illinois Department of Insurance reviews rates and plan designs to ensure compliance with state and federal standards.
- Integrated eligibility: A single application determines eligibility for marketplace plans, premium tax credits, Medicaid, and All Kids (Illinois CHIP).
Over 330,000 Illinois residents enroll in marketplace coverage, with a substantial majority receiving financial assistance.
