Health Insurance in Chicago, IL

Health Insurance Plans Available in Chicago

Residents of Chicago, Illinois can shop for ACA marketplace health insurance plans during Open Enrollment (November 1 – January 15 each year) or during a Special Enrollment Period triggered by a qualifying life event such as losing employer coverage, getting married, having a child, or moving. Marketplace plans are available to all legal residents regardless of health history, and premium tax credits may significantly reduce your monthly cost based on household income.

Which carriers sell in Chicago is set by the plans filed with Get Covered Illinois, and it varies by county and ZIP code; the exchange lists every plan for your address when you shop. Plans are sold in metal tiers from Bronze (lower premium, higher deductible) up through Gold, and Platinum where a carrier offers it.

How Residents in Chicago Buy Coverage

Illinois does not use HealthCare.gov. Chicago residents enroll through Get Covered Illinois, the state-based exchange, which publishes its own carrier list and county-level rates each autumn. Deadlines and special enrollment rules can differ from the federal marketplace — confirm current dates on Get Covered Illinois before enrolling.

Network Types in Chicago

Which network types are sold in Chicago depends on the plans filed with Get Covered Illinois for your county; check the plan type on each listing before you enrol.

PPO plans cover in-network providers without referrals and usually pay something out of network. HMO plans generally need a primary-care referral for specialists and pay nothing out of network except in emergencies. EPO plans also pay nothing out of network, but usually need no referral. If you see specialists or use a particular hospital, the network matters more than the plan label.

ACA Subsidies for Chicago Residents

Premium tax credits are set by household income against the federal poverty level and by the cost of the benchmark plan where you live, so two people with the same income in different counties can receive different credits.

For a single adult in 2026 credits run from about $15,650 up to $62,600 of income, and to $128,600 for a family of four. Above 400% of poverty the credit stops completely — the enhanced rules that removed that cap expired on 31 December 2025.
