A qualifying life event (a move, a new baby, losing other coverage) opens a Special Enrollment Period at other times of year.
Where do I buy health insurance in Illinois?
Illinois residents enroll through Get Covered Illinois. You can also buy off-Marketplace plans, health sharing, or supplemental coverage directly.
Is Medicaid available in Illinois?
Yes. Because Illinois expanded Medicaid, adults under a certain income may qualify regardless of family status. Eligibility is based on income and household size.

It depends on your age, county, plan tier, and — most importantly — whether you qualify for a subsidy. Many Illinois enrollees pay well under $100/month after ACA premium tax credits. Use our calculators to estimate your cost.
