Illinois Mini-COBRA lets you keep your employer’s group health coverage for up to 12 months after you lose it, and it applies even when your employer is too small to fall under federal COBRA. The rules sit in 215 ILCS 5/367e and cover all fully insured group health plans in Illinois regardless of employer size, though the program matters most to workers at companies with fewer than 20 employees, since those employers are exempt from federal COBRA.
Who Qualifies
You’re eligible if you were continuously covered under your employer’s group health plan for the three months immediately before your employment ended or your hours dropped below the plan’s minimum. Dependents who were on the plan at that point qualify on the same terms.
The qualifying events are narrow. Only two trigger Illinois continuation rights: termination of employment, or a reduction in hours that causes you to lose coverage. That’s a real boundary. Federal COBRA also treats divorce, a spouse’s death, and Medicare eligibility as qualifying events, but the Illinois statute does not. Those broader triggers belong to federal COBRA, which applies to employers with 20 or more employees.
One point that helps Illinois workers: the state law does not exclude employees fired for gross misconduct. Federal COBRA does. Under Illinois continuation law, the reason for your termination generally doesn’t disqualify you.
You cannot elect continuation coverage if you’re already covered by Medicare or by another group health plan that you weren’t on before the qualifying event.
The Election Deadline
Your employer must give you written notice of your continuation rights within 10 days of your termination or reduction in hours. If you’re not available in person, the employer must mail the notice to your last known address within the same 10-day window.
Once you have notice, you must request continuation coverage in writing. You get 30 days from whichever comes later: the date your employment ended or your hours were reduced, or the date you received the notice. There’s also a hard outer limit. You cannot elect coverage more than 60 days after the qualifying event itself, no matter when the notice arrives.
Miss the window and your continuation rights end. If your employer sends notice late, the 30-day clock doesn’t start until the notice reaches you, but the 60-day ceiling still runs from the qualifying event, so a delayed notice effectively shortens your decision time.
What the Coverage Includes
Your continuation coverage mirrors the group plan’s hospital, surgical, and major medical benefits. If you had a PPO or HMO, the same network and benefit structure carries over. Dependents who were covered at the time of the qualifying event stay on the plan.
Dental, vision, and prescription drug benefits are not guaranteed. The statute allows insurers to exclude these supplementary benefits from continuation coverage, along with disability income and specified disease coverage. If your employer bundled any of them as separate add-ons rather than as part of the core medical plan, you may lose them when you shift to continuation. Check your plan documents or ask your insurer before assuming everything carries over.
How Long It Lasts
The maximum duration is 12 months from the date your coverage would otherwise have ended. That’s shorter than federal COBRA’s 18-month baseline and its possible 36-month extension for certain qualifying events. Illinois Mini-COBRA also has no disability extension, unlike federal COBRA, which can stretch to 29 months for individuals the Social Security Administration determines are disabled.
The 12-month clock runs from the original loss of coverage, not from the date you elect. Waiting 45 days to enroll doesn’t buy you extra time at the back end.
Coverage can end sooner if any of the following happens:
- You become eligible for Medicare.
- You gain coverage under another group health plan that you weren’t enrolled in before the qualifying event.
- You miss a premium payment. The statute requires timely payment, and falling behind terminates your coverage.
- Your employer’s group plan ends entirely and isn’t replaced with another group policy.
What You’ll Pay
You pay the full group premium, including the portion your employer previously covered. That’s usually the biggest shock. If your employer was paying 70% of a $600 monthly premium, your paycheck showed $180. Under continuation, you owe the full $600.
Illinois continuation law caps your premium at the group rate with no administrative surcharge. Federal COBRA lets employers add a 2% administrative fee on top, bringing the total to 102% of the group rate. On Illinois Mini-COBRA, that surcharge isn’t allowed.
The statute requires timely payment but doesn’t spell out a grace period the way federal COBRA regulations do. Treat your due date as a hard deadline. A missed payment is grounds for immediate termination of coverage.
HSA Funds and Tax Deductions
Money in a Health Savings Account can be used to pay continuation coverage premiums. IRS guidance lists COBRA continuation coverage as a qualified HSA expense, along with premiums paid while receiving unemployment compensation and qualified long-term care insurance premiums. Regular health insurance premiums generally aren’t HSA-eligible, but continuation coverage is an explicit exception.
If you’re self-employed after leaving your job, you may be able to deduct continuation premiums as a self-employed health insurance deduction on Schedule 1. If you’re not self-employed, the premiums can still count toward the medical expense deduction on Schedule A if you itemize and your total medical expenses exceed 7.5% of your adjusted gross income. Most people won’t clear that threshold on premiums alone, but combined with other medical costs in the same year, they might.
What Your Employer Must Do
Employers with fully insured group health plans have three core obligations under 215 ILCS 5/367e. They must provide written notice within 10 days of the qualifying event, delivered in person or mailed to your last known address. They must offer the same hospital, surgical, and major medical benefits available to active employees under the group plan. And they cannot charge more than the group rate for continuation coverage.
The notice requirement is the one employers most commonly fumble.
If Your Employer Doesn’t Comply
The Illinois Department of Insurance oversees the continuation law. If your employer or insurer fails to offer continuation coverage, provides inaccurate notice, or treats you differently from active employees in a way that violates the law, you can file a complaint with the Department. It investigates complaints involving coverage disputes, premium issues, and policy cancellations, among other matters. You can submit online, by email at DOI.complaints@illinois.gov, or by fax at (217) 558-2083. You’ll receive a written response.
Mini-COBRA or the ACA Marketplace
Losing your job or your employer-sponsored coverage also opens a Special Enrollment Period on the federal Health Insurance Marketplace. You have 60 days from the date you lose coverage to enroll in a Marketplace plan, and the same 60-day window opens again when your 12-month continuation coverage expires. You don’t have to wait for Open Enrollment.
Marketplace plans may cost less than continuation coverage, especially if your household income qualifies you for premium tax credits. On the other hand, if you’re mid-treatment with providers in your employer’s network, keeping that plan for a few months while you transition care may be worth the higher premium. You can start on Mini-COBRA and switch to a Marketplace plan later, but time the switch carefully. Ending Mini-COBRA voluntarily doesn’t always trigger a new Special Enrollment Period, so the safer move is to enroll in Marketplace coverage before your continuation period runs out.
