Illinois moved off HealthCare.gov recently enough that a good share of the advice online still points you at the wrong site, and the wrong deadline with it.
My Illinois license runs under NPN 22091157, which is also the license number, and it is public record.
Illinois now runs its own marketplace
The marketplace is Get Covered Illinois, and the word to hold onto is new. Illinois only recently took this over from HealthCare.gov, which means two things. Search results still send people to the federal site, and the state now owns its own calendar rather than inheriting one.
For 2027 that calendar reads November 1 to January 15. The date that actually costs you money is December 15, because missing it pushes your start to February and leaves January uncovered. Nothing about the underlying protections changed in the move: no health questions, no surcharge for a condition, subsidies still set by projected income. The open enrollment guide goes deeper.
Illinois also has a private market outside the exchange. Many plans sold there aren't ACA plans; those can ask about your health, turn an applicant down, and take applications year round, which sometimes makes them a better fit for a healthy buyer who earns too much for a subsidy. They are a different product with different rules, not the same coverage at a discount. The private plans vs. the marketplace guide lays out the difference. I quote both, side by side.
Illinois expanded Medicaid
Worth stating plainly, because it is not true in every state I am licensed in. Illinois expanded Medicaid, so low income adults are not stranded in the coverage gap that exists in Florida, Georgia, Tennessee, Texas and South Carolina. If your income is low, or it moves around from month to month, there is a genuine floor underneath you. The estimate you put on your application still matters, because it decides which program you land in, so if your income is hard to predict, say so before we choose anything.
Chicago networks are not downstate networks
Whether a plan covers your hospital is a network question, not a brand question, and Illinois is a state where that bites. The systems that anchor a plan in Chicago and the collar counties are not the ones that anchor it in Peoria, Rockford or southern Illinois, and two plans at the same premium can treat the same hospital completely differently. If you travel between the two, or your specialist is in the city and you are not, that needs checking before you enroll, not after. It is part of every quote I run.
If you work for yourself, everything in the self-employed guide applies here: the premium deduction, estimating a variable income, and the marketplace versus private decision.
Questions Illinoisans actually ask
Can an out-of-state broker help me in Illinois?
Yes. I am licensed in Illinois under NPN 22091157. Worth knowing that a broker costs you nothing here or anywhere else, because the commission is built into the premium whether you use one or go direct. Going alone does not save you money, it just means nobody checks your networks.
Does Illinois use HealthCare.gov?
Illinois moved to its own state marketplace, Get Covered Illinois. Same ACA rules, different website and a different calendar from the federal site.
When is open enrollment in Illinois?
November 1, 2026 through January 15, 2027 for 2027 coverage. Get Covered Illinois runs its own dates now, and for this year they line up with the federal window, which will not necessarily hold. December 15 is the cutoff for a January 1 start. The open enrollment guide covers what happens if you miss it.
Did Illinois expand Medicaid?
Yes. Illinois expanded Medicaid, so there is no coverage gap here of the kind that exists in non-expansion states. Your income estimate still decides which program you qualify for.
What does health insurance cost in Illinois?
It depends on your age, your county, your income, and whether a private-market or marketplace plan fits better. Text me your zip code and age and I will give you real numbers the same day.
Want both quotes for your Illinois zip code?
Send me your situation and I will show you both doors, with real numbers, in one conversation. Free, no pressure.
Get my options →The bottom line
Illinois expanded Medicaid, so the income floor is real and the gap that catches people in Georgia and South Carolina does not exist here. What does catch people is geography. A plan built around Chicago networks can leave you short downstate, and the reverse is just as true.
Tell me your zip and the doctors you already see, and I will tell you which plans actually cover them. That is the part a comparison site will not do for you.
