Health Insurance in Illinois: Plans, Marketplace, and Costs

Health insurance in Illinois benefits from a competitive marketplace, expanded Medicaid, and a state government that has actively worked to reduce the uninsured rate. Whether you live in Chicago, the suburbs, or downstate communities, understanding health insurance Illinois options helps you find coverage that balances affordability with comprehensive care. This guide covers the state marketplace, typical costs, Medicaid and All Kids, the major insurers, enrollment timing, and where to get free help — with the caveat that programs, subsidies, and enrollment platforms change, so verify current details before you enroll.

Illinois has been a strong supporter of the Affordable Care Act, expanding Medicaid early and investing in enrollment outreach. With over 12.5 million residents, the state offers a diverse insurance landscape shaped by its mix of urban, suburban, and rural populations.

The Illinois Health Insurance Marketplace

Illinois has moved to a fully state-based marketplace, operating under the name Get Covered Illinois. This is an important change: in earlier years Illinois used the federal HealthCare.gov platform for enrollment while managing outreach at the state level, but the state has since launched its own official marketplace and enrollment website at getcovered.illinois.gov (with enrollment through enroll.getcovered.illinois.gov). Because this transition has been phased in around the 2026 plan year, confirm the current enrollment site before you shop — if you land on HealthCare.gov, you may be redirected to the Illinois state platform.

The state-run model gives Illinois residents:

• A dedicated state enrollment platform: Get Covered Illinois hosts plan shopping, comparison, and enrollment on its own site rather than the federal exchange.
• State-directed outreach and assistance: Get Covered Illinois coordinates local navigators, certified assisters, enrollment events, and multilingual support 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 helps determine eligibility for marketplace plans, premium tax credits, Medicaid, and All Kids (Illinois CHIP).

Hundreds of thousands of Illinois residents enroll in marketplace coverage each year, with a substantial majority receiving financial assistance. Free help is available by phone at 1-866-311-1119, through live chat, or from certified local assisters. There is also a Tax Time Easy Enrollment Program that helps residents who missed the standard window connect to coverage.

Average Health Insurance Costs in Illinois

Health insurance Illinois costs are generally in line with or slightly below national averages, particularly in the Chicago metropolitan area where insurer competition is strongest. The figures below are approximate and change every plan year, so use them as a rough guide and confirm exact premiums when you shop.

• Benchmark Silver plan premium: commonly in the range of roughly $470–$550 per month for a 40-year-old before subsidies (varies by rating area and year).
• Bronze plans: often around $300–$380 per month before subsidies.
• Gold plans: approximately $540–$640 per month before subsidies.
• After subsidies: many Illinois residents pay well under $100 per month after premium tax credits, and some qualify for very low or $0-premium Bronze or Silver plans — though this depends heavily on the status of enhanced subsidies (see below).

The Chicago metro area, home to the majority of the state’s population, tends to have the most competitive pricing due to multiple insurers vying for enrollees. Downstate and rural areas may see higher premiums with fewer insurer options.

A Note on Enhanced Premium Tax Credits

The enhanced premium tax credits first enacted in 2021 (which increased subsidy amounts and removed the old 400%-of-poverty income cliff) were scheduled to expire at the end of 2025 unless extended by Congress. Whether they were extended has a major effect on what Illinois residents pay in 2026: if the enhanced subsidies lapse, net premiums for many enrollees would rise, and higher-income households just above 400% of the poverty level could lose subsidy eligibility entirely. Because this is a fast-moving policy question, verify the current status of premium tax credits — through Get Covered Illinois, HealthCare.gov, or KFF — before you assume a particular monthly cost. Do not lock in a budget based on a prior year’s subsidy amount.

Medicaid Expansion in Illinois

Illinois was an early Medicaid expansion state, extending coverage to adults with incomes up to 138% of the federal poverty level starting in 2014. The state has consistently maintained strong Medicaid enrollment and benefits.

Illinois Medicaid covers:

• Expansion adults: individuals aged 19–64 with incomes up to 138% FPL.
• Children: through Medicaid and All Kids, covering children in families across a range of incomes, with additional tiers (with premiums) for higher-income families.
• Pregnant individuals: with income limits set above the adult threshold, plus extended postpartum coverage.
• Seniors and individuals with disabilities: multiple pathways based on specific eligibility criteria.
• Immigrant adults: Illinois has extended Medicaid-like coverage to income-eligible older immigrants through the Health Benefits for Immigrant Adults/Seniors programs; verify current age thresholds and enrollment status, as these programs have been adjusted over time.

Illinois Medicaid operates primarily through managed care, with most enrollees choosing a managed care organization. Major MCOs have included Meridian (Centene), Molina Healthcare, Blue Cross Community Health Plan, and CountyCare (a Cook County plan).

The state’s All Kids program is notable for providing coverage to uninsured children in Illinois regardless of immigration status or pre-existing conditions, with premiums and cost-sharing scaled to family income.

Major Health Insurance Companies in Illinois

Illinois has a robust insurance market with strong competition, particularly in the Chicago area:

• Blue Cross Blue Shield of Illinois: the largest insurer in the state, offering extensive HMO and PPO networks across Illinois counties.
• Ambetter (Centene): a major marketplace presence with competitive pricing in multiple Illinois markets.
• Molina Healthcare: offers affordable plans focused on underserved communities.
• Oscar Health: available in the Chicago metropolitan area with technology-driven plan designs.
• Cigna: participates in select Illinois rating areas.
• Aetna CVS Health: available in Chicago and suburban markets.
• Quartz: serves portions of northern Illinois near the Wisconsin border.

Chicago-area residents may have several insurer options, while rural downstate counties may have only two or three choices. The breadth of Blue Cross Blue Shield of Illinois helps ensure at least one major insurer is available statewide. Insurer participation changes yearly, so confirm which carriers serve your county when you shop.

Open Enrollment and Special Enrollment

Open Enrollment for Illinois marketplace plans has generally run from November 1 through mid-January (often January 15), with coverage selected by mid-December typically starting January 1 and later enrollments starting the first of the following month. As a state-based marketplace, Illinois can set its own dates, so verify the exact deadlines on Get Covered Illinois for the current year.

Special Enrollment Periods are available for qualifying life events:

• Loss of qualifying health coverage
• Marriage or divorce
• Birth, adoption, or foster care placement
• Relocation to a new coverage area
• Changes in household income or size
• Loss of Medicaid eligibility

Medicaid and All Kids applications are accepted year-round through the Illinois Application for Benefits Eligibility (ABE) system or at local offices.

Subsidies and Financial Assistance

Illinois residents can access substantial financial help for marketplace coverage:

• Premium tax credits: available for eligible households; the exact income range and amounts depend on whether enhanced subsidies remain in effect (see the note above).
• Cost-sharing reductions: available on Silver plans for lower-income enrollees (generally 100%–250% FPL), reducing deductibles, copays, and out-of-pocket maximums.
• Medicaid: free comprehensive coverage for those meeting income requirements.
• All Kids: coverage for uninsured children regardless of immigration status, with costs scaled to income.

Unique Features of Illinois’s Insurance Market

• All Kids program: Illinois’s nationally recognized CHIP program covers uninsured children, including those who are undocumented, making it one of the more inclusive children’s coverage programs in the country.
• Health Benefits for Immigrant Adults/Seniors: the state has extended Medicaid-like coverage to income-eligible older immigrants; verify current eligibility, as the program has evolved.
• Cook County safety net: CountyCare, the Cook County managed care plan, provides coverage integrated with the county’s public hospital system (Cook County Health), offering a safety-net option for Medicaid enrollees in the Chicago area.
• State-based marketplace: Illinois now runs its own marketplace and enrollment platform, allowing for local control over outreach, plan management, and enrollment periods.
• Network adequacy downstate: rural Illinois faces provider shortages, particularly for specialists, making network adequacy a key consideration for plan selection outside the Chicago metro.

Frequently Asked Questions

Is there a penalty for not having health insurance in Illinois?

No. Illinois does not impose a state individual mandate penalty for being uninsured, and the federal penalty has been $0 since 2019. However, going without coverage means you assume full financial risk for medical expenses.

Where do I enroll in an Illinois marketplace plan?

Illinois now uses its own state marketplace, Get Covered Illinois, at getcovered.illinois.gov (enrollment through enroll.getcovered.illinois.gov). You can shop and enroll there, get free help from certified assisters, or call 1-866-311-1119. If you start at HealthCare.gov, you may be directed to the state platform. Verify the current site each year, since the transition has been phased in.

What is the All Kids program?

All Kids is Illinois’s children’s health insurance program that covers uninsured children under 19 living in Illinois, regardless of immigration status, pre-existing conditions, or family income. Coverage is free for families with the lowest incomes and available at sliding-scale premiums for higher-income families. Apply year-round through the ABE system.

How do I apply for Illinois Medicaid?

You can apply online through the Illinois ABE (Application for Benefits Eligibility) portal at abe.illinois.gov, by phone, by mail, or in person at a local Department of Human Services office. Applications are accepted year-round. You can also begin a Medicaid application through the marketplace, which routes eligible applicants to the state Medicaid agency.

Can I see any doctor with a marketplace plan in Illinois?

Not necessarily. Each plan has a specific provider network. HMO plans require you to stay in-network and often require referrals for specialists. PPO plans offer more flexibility for out-of-network care but at a higher cost. Always verify your preferred doctors and hospitals are in-network before enrolling.

Practical Takeaway

Health insurance Illinois residents can access is strengthened by competitive marketplace options, early Medicaid expansion, and inclusive programs like All Kids. Start at Get Covered Illinois (getcovered.illinois.gov) to compare marketplace plans and check your subsidy eligibility, and confirm the current enrollment site and deadlines since the state has transitioned to its own platform. If your income qualifies you for Medicaid, apply year-round through the ABE portal. Chicago-area residents will find the most competitive insurer landscape, while those in rural Illinois should carefully evaluate provider networks. Above all, verify the status of enhanced premium tax credits before budgeting, because that policy decision has an outsized effect on what you actually pay.
