Illinois has a large individual market anchored by metro Chicago, with a substantial population of self-employed professionals, freelancers, and small-business owners.
Here's what you need to know about finding the right plan in the Prairie State.
The Illinois Health Insurance Landscape
Illinois expanded Medicaid under the ACA, covering many lower-income residents. For self-employed and higher-income residents above those limits, the individual market is the main route to coverage.
Blue Cross Blue Shield of Illinois is the dominant carrier, alongside Aetna, Cigna, Ambetter, and UnitedHealthcare.
ACA Marketplace Options in Illinois
Illinois has been transitioning toward its own state-based marketplace, Get Covered Illinois. You enroll during Open Enrollment (roughly November through mid-January) or a Special Enrollment Period after a qualifying life event.
The Chicago metro has the most plan options; premiums downstate are often lower than in the city.
💡 Illinois tip: Chicago-area premiums can run high on the marketplace. If you're healthy and self-employed, a privately underwritten plan often delivers better value than a comparable Silver plan.
Private Health Insurance in Illinois
For healthy Illinoisans — especially Chicago's large base of freelancers, consultants, and small business owners who don't qualify for subsidies — the private medically underwritten market is frequently the best value, with lower premiums for healthy applicants.
A healthy 40-year-old in Chicago might save a meaningful amount monthly versus a comparable Silver ACA plan, given the metro's higher marketplace pricing.
Illinois-Specific Considerations
High Chicago premiums
Marketplace premiums in Cook County and the collar counties can be steep. Healthy applicants often do noticeably better in the private market.
Downstate vs. Chicago
Pricing and networks differ sharply between Chicago and downstate Illinois — where you live materially affects your options.
A large freelance economy
Chicago's professional, creative, and tech freelancers rarely get employer coverage, making individual plans their default.
How to Find the Best Plan in Illinois
Illinois residents — especially in the Chicago metro — should compare private options closely, since marketplace pricing runs high.
- Determine your income and whether you'd qualify for any ACA subsidies
- Assess your health history — are you a good candidate for medically underwritten plans?
- Work with an independent agent who has access to both ACA and private-market options
- Compare total cost — premium, deductible, and out-of-pocket maximum
- Confirm your doctors and hospitals are in network before enrolling
