Short-Term Health Insurance in Illinois: 2027 Rules
A short-term health plan in Illinois is a temporary policy meant to fill a gap of weeks or a few months, not a full replacement for major medical coverage. It can exclude pre-existing conditions, cap what it pays and decline applicants, and Illinois adds its own rules on top of the federal limits. With Illinois Marketplace premiums rising 14% to 14.1% on average for 2027, more people are looking at short-term plans, so it pays to know what they leave out. I don't sell short-term plans; this page explains how they work in Illinois and the year-round options I do offer.
Private health insurance in Illinois
Most people I help in Illinois end up on a private plan, not a Marketplace plan. Private, medically underwritten health insurance is priced on your age, zip code and health instead of your income, so a strong year never raises your premium and there is no tax credit to pay back in April.
Why people leave the Marketplace
- Premiums keep climbing. Illinois Marketplace premiums are rising 14% to 14.1% on average for 2027.
- The subsidy cliff. Above 400 percent of the poverty level ($63,840 for one person, $132,000 for a family of four) you pay full price.
- Surprise tax bills. Underestimate your income and you repay the tax credit in April.
- Narrow networks. Many plans are local HMOs or EPOs that need referrals and cover little outside the area.
- High out-of-pocket costs. 2027 out-of-pocket maximums reach $12,000 per person and $24,000 per family.
- One window a year. Outside open enrollment you need a qualifying life event to enroll or switch.
What a private plan does differently
- Start any month. If approved, coverage can begin the first of next month, with no wait for open enrollment.
- Networks that travel. Many private plans use national PPO networks, which can give you in-network doctors outside Illinois too. Networks vary by plan.
- Can cost less than full-price Marketplace plans for some healthy applicants above the subsidy line.
- Accident coverage the Marketplace does not offer. A private plan can be paired with accident coverage, a separate policy. What it includes varies by plan.
- Approval is based on health. You answer health questions, and acceptance is not guaranteed.
With a significant health condition, or income low enough for a large tax credit, a Marketplace plan can be the better fit, and I will tell you if it is. Either way you see both side by side.
Private plans are not ACA Marketplace plans. Benefits, exclusions and pre-existing condition rules differ by plan and by state, so review the plan details before you enroll.

Short-term plan rules in Illinois
Illinois bans short-term limited-duration insurance. Public Act 103-0649, signed in July 2024, added Section 352c to the Illinois Insurance Code: since January 1, 2025, no company may issue, deliver, amend or renew a short-term plan for an Illinois resident, and the old Short-Term, Limited-Duration Health Insurance Coverage Act was repealed. Before that, state law capped these plans at six months with no renewals. A 2026 bill to undo the ban (SB 2757) stalled in the Senate in March 2026. Federal non-enforcement of the 2024 four-month rule, announced in August 2025 with replacement rulemaking still pending as of late 2026, does not override a state ban. The Illinois Department of Insurance regulates health coverage sold in the state.
When a short-term plan fits in Illinois, and what to use instead
Since short-term plans can't be sold to Illinois residents, a Chicago restaurant worker between jobs or a downstate manufacturing employee waiting on new benefits needs another bridge. Be wary of out-of-state sellers or non-insurance products pitched as substitutes; they may exclude prior conditions and don't qualify for tax credits. Illinois now runs its own exchange, Get Covered Illinois, which replaced HealthCare.gov for 2026 coverage, and losing employer coverage opens a 60-day special enrollment window there. Frank can also help with a year-round medically underwritten private plan; if approved, it can take effect the first of a month, offering a path outside the enrollment calendar.
The Illinois individual market
Illinois buyers use Get Covered Illinois, the state's own exchange since the 2026 plan year. Final 2027 individual rates rise about 14 percent on average across five insurers, and two insurers are leaving the exchange, so some enrollees must pick new plans. Illinois now requires prior approval of individual and small-group rates. The state banned short-term plans in 2025, so the alternatives to Marketplace coverage are private, medically underwritten plans and employer or union coverage. Continuation rights are relatively strong: 12 months for employees, and up to two years, or until Medicare for those 55 and older, for divorced or widowed spouses.
Other Illinois rules to know
- Leaving a small employer: Illinois requires insured group plans to offer up to 12 months of continuation after three months of coverage, and gives divorced or widowed spouses up to two years, or until Medicare if they are 55 or older.
- Short-term plans: Illinois banned new short-term health plans starting January 1, 2025.
- Where to enroll: Illinois uses its own exchange, Get Covered Illinois, which replaced HealthCare.gov for 2026. Get Covered Illinois sets its own open enrollment dates; check its site for 2027 deadlines. Private, medically underwritten plans can start the first of any month if approved.
- 2027 rates: individual plans 14% to 14.1% on average, small-group plans about 17.6%. See the Illinois 2027 rate page.
What a short-term plan is
Short-term limited-duration insurance is temporary coverage outside the ACA rules. It can ask health questions, turn applicants down, exclude conditions you already have and leave out benefits such as maternity care, mental health care or prescriptions. It is not Marketplace coverage, so no subsidy applies to it.
Why the time limit matters
A 2024 federal rule caps short-term plans at three months, or four with renewals. In August 2025 federal regulators said they would not prioritize enforcing that cap, so the real limit now depends on your state, from a few months to as long as three years. However long it lasts, when the plan ends you are not guaranteed a new one, and losing a short-term plan does not open a Marketplace enrollment window.
The two options that last all year
A Marketplace plan accepts everyone during open enrollment or within 60 days of losing other coverage. A medically underwritten private plan is year-round coverage priced on age, ZIP code and health; it is not a Marketplace plan, approval depends on your health answers, benefits vary by plan, and if approved it can start the first of a month. For most people who need more than a short bridge, one of these two is the better fit.
For 2027 the Marketplace credit stops at 400 percent of the poverty level: $63,840 for one person, $86,560 for two and $132,000 for a family of four. The out-of-pocket maximum for 2027 Marketplace plans is $12,000 for one person and $24,000 for a family. The full guide covers the rest.
