Insurance & Open Enrollment in Illinois: A 2026–27 Guide for Families of Kids with Special Needs

You've got enough on your plate. This guide walks through what changed this year, what to check in your plan, and how to keep your child's therapy going without a gap in coverage. It takes about ten minutes to read, and you can skip straight to whichever section fits your family.

Start here: the deadline moved

Open enrollment opens November 1, 2026. The closing date is the part that changed, and it's the change most likely to catch families off guard. Illinois enrollment for 2027 coverage starts November 1, 2026, and a new federal rule says it can't run past December 31. Get Covered Illinois

picks the exact closing day, so check getcovered.illinois.gov before you build your plan around a date. In past years, if you signed up after mid-December, your coverage simply started February 1 instead of January 1. That option is gone, and every plan selected during open enrollment now starts January 1.

So if you miss the deadline this year, you don't get later coverage. You get no coverage until the next enrollment season or a qualifying life event. That's a meaningful difference for a family whose child has ongoing therapy authorizations.

Two other things to know before you shop

You may have fewer plans to choose from than last year. Illinois had 11 marketplace insurers in 2025, dropped to 7 in 2026, and another one is leaving for 2027. When an insurance company exits, the remaining plans redraw their provider networks, which means your BCBA could be in-network this year and out next year even though nothing about your family changed.

Help with premiums is also unsettled right now.

The extra federal help with premiums ended December 31, 2025, and the House voted in January 2026 to bring it back for three years before sending it to the Senate. As of spring 2026, the Senate hadn't voted on it.

Premiums rose roughly 26% for 2026, which was the biggest jump since 2018. That combination makes it worth actually checking what financial help you qualify for rather than assuming it matches last year. Get Covered Illinois is the only place that shows you the current numbers.

Which situation are you in?

You get insurance through work. Your employer sets the dates, usually sometime in the fall, and HR will announce them. This is your window to switch plans, add your child, or change your FSA or HSA, so ask whether your child's providers are in-network for next year before you renew automatically.

You buy your own insurance. Shop at getcovered.illinois.gov starting November 1, since Illinois now runs its own marketplace instead of using HealthCare.gov. Financial help is only available through the state site, so make sure the web address ends in .gov before you enter any information.

Your child is on Medicaid or All Kids. Illinois Medicaid covers ABA for kids ages 0 to 20 with an autism diagnosis, and you'll need prior authorization for it. Medicaid enrolls people year-round, so the open enrollment deadline doesn't apply to your child's coverage.

Medicaid is changing in January 2027

Most Illinois families haven't heard about this yet, so here's the plain version. Starting January 1, 2027, federal law requires Illinois to add work requirements for certain adults on Medicaid and to check eligibility more often than before. Illinois Healthcare and Family Services

Your child isn't affected by any of this. Kids' Medicaid and All Kids eligibility work differently, and this rule targets one specific group of adults. Most parents aren't affected either, which is worth saying clearly before the details.

The rule applies to adults ages 19 to 64 who aren't on Medicare and aren't parents or guardians of dependent children. Some people are exempt regardless, including people with disabilities and people with mental health diagnoses. If you fall into either group, the requirement shouldn't reach you at all.

If you're on Medicaid yourself, here's the part to check. If your child is 13 or younger, the work requirement doesn't apply to you, and if your child is 14 or older, you can likely get a caregiver exemption when your child is disabled. Apply for the exemption either way, because confirming it in writing is easier than fixing it after a coverage lapse.

There's one more change coming alongside it. Adults in this group will renew their Medicaid every six months instead of once a year, starting with renewals on or after December 31, 2026. Twice as many renewals means twice as many chances for a letter to go unanswered.

HFS says the single most important thing you can do right now is make sure they have your current address. They plan to mail details to affected families in September 2026. Open every letter from the State of Illinois this fall, including the ones that look like routine paperwork. Illinois Healthcare and Family Services. Check medicaid

What Illinois law says about ABA

Illinois requires insurance plans to cover autism diagnosis and treatment for anyone under 21, and the law mentions a $36,000 yearly maximum. That cap may not apply to your family, though. Most newer plans treat ABA as an Essential Health Benefit, and those plans generally can't put a yearly dollar cap on it.

So ask your plan one question: are we grandfathered? If the answer is no, you probably shouldn't see a dollar cap on ABA at all. You might still run into limits on hours or visits, and you'll almost certainly still need prior authorization.

There's a second catch worth understanding. State autism laws mostly apply to plans that the state regulates. Large employers often use self-funded plans that follow federal rules instead, which is why two families working at the same company can end up with completely different ABA benefits. Ask your HR team whether your plan is fully insured or self-funded.

Two recent changes that help

Illinois has continued enforcing federal mental health parity rules for state-regulated plans. In plain terms, that means a plan can't make behavioral health harder to use than regular medical care, including by adding extra hurdles to get services approved.

Illinois also passed a law in July 2025 removing prior authorization for many outpatient mental health services in state-regulated plans. Rollout timing varies from plan to plan, and ABA often carries its own separate rules. Call your plan and confirm rather than assuming the change reached your child's services.

Your ten-minute plan checkup

Print this and go through it once. Every item here is something a plan representative can answer on a single phone call.

• What kind of plan is this? Work plan, self-funded, or marketplace?

• Is it grandfathered? If yes, ask about the $36,000 cap and how it works.

• Is my BCBA in-network for 2027? If not, ask about out-of-network benefits or a single case agreement.

• Does ABA need prior authorization? What paperwork, and how long does approval take?

• What will I pay? Deductible, copay, and yearly out-of-pocket maximum.

• Are there limits on hours or visits? Some Medicaid plans flag anything above 40 hours a week.

• If my child has two plans, how do they coordinate with each other?

• If I'm switching plans, can I get transition of care so the authorization doesn't lapse?

Do this now

1. Confirm Illinois's exact deadline at getcovered.illinois.gov, then work backward from it.

2. List every provider your child sees. ABA, speech, OT, psych, pediatrician. Check each one's 2027 network status.

3. Call your plan and work through the checkup questions above in one sitting.

4. If you're on Medicaid, confirm your plan, confirm your ABA provider is in it, and update your address with HFS.

5. Keep your EOBs. If a claim gets denied, good records are what win appeals.

6. Call us. We'll check your benefits, estimate your costs, and help get authorizations approved.

Questions parents actually ask

"We're on All Kids. Can my child get ABA?"

Yes. Illinois Medicaid covers ABA for kids 0 to 20 with an autism diagnosis, and you'll need prior authorization before services start.

"Our plan says ABA has a dollar cap. Is that allowed?"

Sometimes, but often not. If your plan is grandfathered, Illinois law allows a $36,000 yearly maximum, while newer plans usually can't cap ABA in dollars at all. Ask which kind you have.

"Will the new Medicaid rules stop my child's therapy?"

No. The work requirement starts January 2027 and applies to certain adults, not to children, and generally not to parents of dependent children.

"What if I miss the deadline?"

You'd need a qualifying life event, such as a job change, a move, or a new baby. There's no late signup option this year, which is exactly why December matters more than it used to.
