Full answer: It depends on which dual-eligible tier applies. Illinois residents who qualify for full Illinois Medicaid on top of Medicare (usually through the Aid to the Aged, Blind, and Disabled program or SSI) get nearly all Medicare premiums, deductibles, and coinsurance covered, plus Illinois Medicaid extras like dental, vision, hearing aids, and long-term care. Illinois residents who qualify only for a Medicare Savings Program, QMB, SLMB, or QI, get help with Medicare Part A and Part B premiums and, for QMB only, Medicare cost-sharing, but not the full Illinois Medicaid benefit package.
Illinois residents who carry both Medicare and Illinois Medicaid are called dual eligibles, and Illinois is home to a substantial share of the 12 million Americans who fall into this category nationwide in 2026. Being dual eligible in Illinois is not a single status. It splits into full dual eligibility, which layers complete Illinois Medicaid benefits on top of Medicare, and partial dual eligibility through a Medicare Savings Program, which only helps pay Medicare premiums and, in one tier, cost-sharing. Which tier you land in depends on your monthly income, your household size, and in some cases your countable assets.
Illinois dual-eligible enrollees will find in this guide what they actually receive in 2026, the income limits for each tier by household and family size, how to apply through the Illinois Application for Benefits Eligibility (ABE) portal, and what happens if an application is denied.

Direct Answer: What Dual Eligibles Get in Illinois
It depends on which dual-eligible category you fall into. Illinois residents who have both Medicare and full Illinois Medicaid get nearly all Medicare premiums, deductibles, and coinsurance covered, plus Medicaid extras like dental, vision, and long-term care. Illinois residents who qualify only for a Medicare Savings Program (QMB, SLMB, or QI) get help with Medicare Part A and Part B premiums and, for QMB, cost-sharing, but not full Illinois Medicaid benefits.
What 'Dual Eligible' Means in Illinois (2026)
Illinois recognizes two dual-eligible tiers, and the difference matters more than most enrollees realize. Full dual eligibles qualify for the complete Illinois Medicaid benefit package on top of Medicare, typically because they meet the income and asset limits for the Aid to the Aged, Blind, and Disabled (AABD) program or receive Supplemental Security Income (SSI). Partial dual eligibles qualify only for a Medicare Savings Program (MSP), which uses Illinois Medicaid funds to pay some or all Medicare premiums and, for the top MSP tier, Medicare cost-sharing, without adding full Medicaid benefits like dental or long-term care.
The Illinois Department of Healthcare and Family Services (HFS) administers full Illinois Medicaid benefits, while the Illinois Department of Human Services (IDHS) processes most Medicare Savings Program and AABD applications through the same statewide intake system. Both full and partial dual-eligible status require the applicant to already be enrolled in Medicare Part A, Part B, or both; Illinois Medicaid cannot pay Medicare premiums for someone who has not yet signed up for Medicare.
Illinois Dual-Eligible Income Limits by Household Size (2026)
Illinois sets the Qualified Medicare Beneficiary (QMB) tier, the entry point for full Medicare cost-sharing help, at 100% of the 2026 Federal Poverty Level. The table below shows that ceiling scaled by household size using the 2026 FPL guidelines for the 48 contiguous states and DC. For a single Illinois applicant, that works out to about $1,330 per month; for a two-person household it is about $1,803 per month, after the standard $20 monthly income disregard Illinois applies to Medicare Savings Program applicants. Illinois residents in Alaska or Hawaii use separate, higher federal poverty figures published by HHS.
Full Medicaid through the Aid to the Aged, Blind, and Disabled program in Illinois uses this same 100% FPL income test in most cases, but adds an asset limit of $17,500 for an individual, well above the $2,000 federal floor most states use. Medicare Savings Program applicants face a tighter asset test: $9,950 for one person and $14,910 for a couple in 2026. Countable assets exclude your home, one vehicle, and most personal belongings.
What Full Dual-Eligible Status Gets You in Illinois
Illinois full dual eligibles get the combined coverage of Medicare and Illinois Medicaid, with Medicare paying first for most medical services and Illinois Medicaid picking up the rest. Illinois Medicaid covers the Medicare Part B premium ($202.90 per month standard in 2026), the Medicare Part A and Part B deductibles ($1,736 and $283 respectively in 2026), and the 20% Part B coinsurance that Original Medicare leaves unpaid. On top of that, Illinois Medicaid adds benefits Medicare does not cover at all: routine dental care, eyeglasses, hearing aids, non-emergency medical transportation, and long-term nursing home or home- and community-based waiver services once a separate long-term care income and asset test is met.
Most Illinois full dual eligibles enroll in a Dual-Eligible Special Needs Plan (D-SNP), a type of Medicare Advantage plan built specifically to coordinate Medicare and Illinois Medicaid benefits under one card, often with $0 premiums and extra perks like an over-the-counter allowance or grocery card. D-SNP enrollment is optional; Illinois dual eligibles can stay on Original Medicare with wraparound Illinois Medicaid instead.
Partial Dual Eligible in Illinois: QMB vs. SLMB vs. QI
Illinois residents who do not meet the AABD asset test can still get help through a Medicare Savings Program, and the three MSP tiers pay for different things. Qualified Medicare Beneficiary (QMB) is the richest tier: it pays the Part A premium (for the small number of Illinoisans who owe one), the Part B premium, and all Medicare deductibles, coinsurance, and copays. Specified Low-Income Medicare Beneficiary (SLMB) and Qualified Individual (QI) pay the Part B premium only, and QI funding is capped annually by the federal government and awarded first-come, first-served each year in Illinois.
Illinois Medicare Savings Program tiers and 2026 monthly income limits| Tier | 2026 Monthly Income Limit | What It Pays |
|---|
| QMB | $1,330 individual / $1,803 couple | Part A and B premiums, deductibles, coinsurance, copays |
| SLMB | $1,331 to $1,595 individual / $1,804 to $2,163 couple | Part B premium only |
| QI | Up to $1,796 individual / up to $2,435 couple | Part B premium only; capped annual funding |

How to Apply for Dual-Eligible Benefits in Illinois
Illinois processes applications for full Medicaid, all three Medicare Savings Program tiers, and AABD through one shared intake system, so applicants do not need to guess which specific program to request. Illinois Medicaid and Medicare Savings Program applications have no enrollment deadline and can be submitted any time of year. Enrolling in a Dual-Eligible Special Needs Plan afterward, however, follows Medicare's own calendar: dual eligibles can switch D-SNPs during the Medicare Annual Enrollment Period (October 15 to December 7, 2026) or during a monthly Special Enrollment Period available to dual eligibles year-round.
- Confirm you are already enrolled in Medicare Part A, Part B, or both before applying, since Illinois Medicaid cannot pay premiums for coverage you have not started.
- Apply online through the Application for Benefits Eligibility (ABE) portal at abe.illinois.gov, Illinois's shared intake system for Medicaid, SNAP, TANF, and Medicare Savings Programs.
- Apply by phone at 1-800-843-6154 or in person at any Illinois Family Community Resource Center if you prefer not to use the online portal.
- Watch for a notice from IDHS within about 45 days for standard applications; AABD applications based on disability can take up to 90 days while a disability determination is completed.
Illinois Is a Medicaid Expansion State: Why That Matters as You Approach Medicare
Illinois expanded Medicaid under the Affordable Care Act effective January 1, 2014, so Illinois adults ages 19 to 64 with income up to 138% of the Federal Poverty Level ($22,025 for an individual, $45,540 for a family of four in 2026) already qualify for Illinois Medicaid before they ever become eligible for Medicare at 65. There is no ACA coverage gap in Illinois the way there is in the 10 non-expansion states (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, and Wyoming). Once an Illinois expansion Medicaid enrollee turns 65 or qualifies for Medicare through disability, their case is redetermined against the stricter, non-MAGI dual-eligible income and asset rules described above, since expansion eligibility ends when Medicare eligibility begins for most adults.
Common Reasons Dual-Eligible Applications Get Denied in Illinois
Illinois denies a significant share of dual-eligible applications for reasons that are fixable once you know what went wrong. Understanding the pattern helps applicants avoid a second rejection.
- Countable income slightly above the QMB, SLMB, or QI limit for the household size, even after the $20 disregard is applied.
- Countable assets above the $9,950 individual or $14,910 couple MSP limit, or the $17,500 AABD limit, often because a second bank account or vehicle was not disclosed correctly.
- Missing proof of Medicare enrollment, such as a Medicare card or Social Security award letter, since Illinois Medicaid cannot pay premiums for Medicare you have not yet enrolled in.
- Incomplete income verification, most often missing pay stubs, Social Security benefit letters, or pension statements for every household member counted.
- Residency or identity documentation gaps, especially for applicants who recently moved to Illinois or lack a current Illinois-issued photo ID.
How to Appeal a Denial in Illinois
Illinois applicants who are denied full Medicaid, AABD, or a Medicare Savings Program have the right to request a state fair hearing through the Illinois Department of Human Services within 60 days of the denial notice. Requests can be filed online through ABE, by phone, or in writing to the address listed on the denial letter, and applicants can ask to keep receiving benefits during the appeal if they file within 10 days of the notice. A local Illinois Legal Aid office or the Illinois Senior Health Insurance Program (SHIP) counselor network can help prepare the appeal at no cost.
Frequently Asked Questions
What is the income limit to qualify as a dual eligible in Illinois for a household of 2 in 2026?
For the QMB Medicare Savings Program tier, a two-person Illinois household qualifies at about $1,803 per month ($21,640 per year at 100% FPL) after the standard $20 income disregard. SLMB extends up to about $2,163 per month for a couple, and QI up to about $2,435 per month. Full Medicaid through AABD generally uses the same 100% FPL income test plus a $17,500 asset limit.
What counts as income for Illinois Medicare Savings Program and AABD eligibility?
Illinois counts Social Security retirement or disability benefits, pensions, wages, and most other regular income, then applies a $20 general income disregard before comparing the total to the limit. Unlike MAGI-based Illinois Medicaid for adults under 65, these non-MAGI dual-eligible categories also apply an asset test that counts bank accounts, stocks, and most property other than your home and one vehicle.
What documents do I need to apply for dual-eligible benefits in Illinois?
You need proof of Medicare enrollment, a Social Security number for each applicant, proof of identity and Illinois residency, recent income documentation like pay stubs or a Social Security award letter, and bank or asset statements if applying for full Medicaid or a Medicare Savings Program. Apply through abe.illinois.gov or a Family Community Resource Center.
What happens if my dual-eligible application is denied in Illinois?
Illinois sends a written denial notice explaining the reason, most often income or assets over the limit, or missing documentation. You can request a state fair hearing through the Illinois Department of Human Services within 60 days, and if you file within 10 days you can typically keep receiving benefits while the appeal is pending. Illinois SHIP counselors can help free of charge.
Can I work and still get dual-eligible benefits in Illinois?
Yes, but earned income counts toward the QMB, SLMB, QI, or AABD income limit for your household size, so working can push you over the threshold. Illinois applies standard earned-income disregards before comparing your income to the limit, and a benefits counselor at your local Family Community Resource Center or SHIP office can run the math for your specific paycheck.
Is Illinois a Medicaid expansion state, and does that affect dual eligibles?
Yes, Illinois expanded Medicaid under the ACA effective January 1, 2014, covering adults up to 138% FPL. That expansion eligibility generally ends when someone becomes eligible for Medicare, at which point Illinois evaluates the case under the stricter non-MAGI dual-eligible rules (QMB, SLMB, QI, or AABD) described in this guide instead.
What is the difference between QMB, SLMB, and QI in Illinois?
QMB is the richest Medicare Savings Program tier: it pays Medicare Part A and Part B premiums plus all Medicare deductibles, coinsurance, and copays. SLMB and QI pay only the Part B premium, with no help toward deductibles or coinsurance. QI also has capped annual federal funding awarded first-come, first-served in Illinois each year.
Does dual-eligible status in Illinois include a Medicare Advantage D-SNP plan automatically?
No. Dual-eligible status in Illinois qualifies you to enroll in a Dual-Eligible Special Needs Plan (D-SNP), but enrollment is optional and must be done separately through Medicare, not automatically through Illinois Medicaid. Dual eligibles can also choose to keep Original Medicare with Illinois Medicaid wraparound coverage instead of a D-SNP.
