When can I enroll in a Illinois Marketplace plan for 2027?

Which insurer has the most doctors in Illinois?

What is the lowest deductible on a Illinois Marketplace plan?
7 plans have a $0 individual deductible. Deductibles run from $0 to $10,600. A lower deductible usually means a higher monthly premium, so compare the out-of-pocket maximum too.
Which plan year does this page cover?
These are Illinois's 2026 plans, the latest available. Illinois's 2027 plan details are not public yet, so prices, benefits and doctors may be different for 2027. Check Get Covered Illinois before you enroll. The doctor lists already include doctors that insurers list for 2027. This page will be updated when the 2027 details come out.
Are all Illinois plans sold in every county?
No. 86 plans are sold only in some counties, and 10 plans are sold statewide. Choose your county above the plan list to see only the plans sold where you live.
Why are there no monthly premiums on this page?
Premiums depend on your age, county, household size and income, and most enrollees get a subsidy, so a single price would mislead. Prices are listed on Get Covered Illinois. This page compares what the plans cover: deductibles, out-of-pocket maximums, coinsurance and networks.

Only individual-market plans sold on Get Covered Illinois are included; small-business (SHOP) and off-exchange plans are left out. A plan an insurer files once per region is shown once.
Doctors listed for 2026 or 2027 plans are counted, because insurer directories already list 2027 networks and most plan IDs carry over.
Deductibles, out-of-pocket maximums and coinsurance are for one person, in network, for the standard version of each plan. Coverage examples (having a baby, managing type 2 diabetes, a simple fracture) are what CMS's standard scenarios cost under each plan.
Directories can be out of date. Call the doctor's office and the insurer to confirm before you enroll.
