How Will Illinois Medicaid Handle Six-Month Redeterminations and Work Requirements?

Updated November 4, 2026, based on the Illinois Department of Healthcare and Family Services (HFS) and CMS as of that date.

Illinois starts both H.R. 1 changes for ACA Adults on January 1, 2027, but each enrollee meets them at their first redetermination in 2027. The HFS Federal Resource Center FAQs say the first group subject to work requirements is people whose redetermination dates fall in March 2027. From that renewal on, ACA Adults renew every six months instead of every twelve.

New applicants feel it sooner. The work requirement applies to anyone who qualifies as an ACA Adult and submits an application after 5:00 p.m. on December 31, 2026. On the same January 1 date, retroactive coverage drops from three months to two for all Illinois Medicaid customers.

This post covers what the Illinois Department of Healthcare and Family Services (HFS) has published; for the federal rules, see our guide to the federal changes. Several HFS webinar decks cited below are marked "Draft – for preliminary discussion only," so details from them may still change.

When each change starts in Illinois

• January 1, 2027: work requirements take effect, six-month renewals begin, and retroactive coverage falls to two months.
• Applications submitted by 5:00 p.m. Central on December 31, 2026: decided under current rules, even if HFS processes them later. If approved, the person meets work requirements at their first 2027 redetermination.
• March 2027: the first redetermination cohort subject to work requirements.

Work requirements and six-month renewals apply only to ACA Adults: generally people 19 to 64 who aren't on Medicare and don't have a related child under 18 in the home. HFS's Module 3 work requirements deck (draft) puts that group at about 700,000 people. Someone exempt from work requirements is still on the six-month schedule.

How Illinois will renew ACA Adults

HFS won't shorten eligibility periods already set in 2026. Its FAQ example: a period that started in June 2026 and ends in May 2027 is renewed under the new rules starting in April 2027. That matches what CMS's six-month renewal slides call option 2, moving people at their next scheduled renewal, though HFS doesn't name an option.

HFS will keep using Form A (ex parte), confirmed from data without contacting the customer, and Form B, which the customer must return. The FAQ warns the new rules may reduce how many renewals can be done ex parte. HFS's Module 6 Q&A deck (draft) says people whose income HFS can verify, and who meet or are exempt from the work requirement, get Form A. Everyone else gets Form B.

Eligibility periods are set per person, so in a mixed household only the ACA Adult moves to six months. Customers can renew in Manage My Case at abe.illinois.gov.

How Illinois will check work requirements

HFS picked the shortest look-back federal law allows. Applicants must have met the requirement in the month before they apply. At renewal, HFS checks one month since the last determination and verifies only at the six-month renewals, not monthly.

A person meets the requirement with $580 a month in income, 80 hours a month of work, community service, a work program or a combination, or half-time school. Income is counted under MAGI and can come from others in the same household group.

HFS checks its own data first. Because HFS and the Illinois Department of Human Services share an eligibility system, people meeting SNAP work rules, or in their three-month SNAP grace period, are marked exempt automatically. Per the Module 3 and Module 4 exemptions decks (both draft), in 2027 HFS will accept self-attestation under penalty of perjury for activities and exemptions its data can't confirm.

If HFS can't confirm compliance, it sends a notice with the redetermination form. The person has 30 calendar days to respond and keeps coverage meanwhile. If they don't show compliance or an exemption, coverage ends at the end of the certification period. Appeals are due within 60 days.

Reporting runs through a screener at abe.illinois.gov, Manage My Case, and a Manage My Work Requirement form that can be mailed, faxed, or dropped off at a Family and Community Resource Center, per the September 1, 2026 member notice.

What changes for providers and health centers

H.R. 1 cuts retroactive coverage to one month for ACA Adults. The HFS Phase 2 toolkit says HFS will provide two months for all eligible applicants anyway, using state funding. For an uninsured patient seen at your center, coverage can reach back only to the two months before the application month, so a prompt application matters more than it did.

HFS has asked providers to help in specific ways:

• Post Phase 1 and Phase 2 toolkit flyers in clinic waiting rooms, and hand out palm cards at check-in or check-out (Module 6).
• Help patients create and log in to Manage My Case accounts. Module 4 urges "all agencies with customer contact" to do this.
• Help patients update their address. A notice that doesn't reach someone can cost them coverage (Module 6).
• If your organization runs a volunteer program, make sure ACA Adults know about it, since community service hours count (Module 3).

Webinar recordings for Modules 1 through 7 are on the HFS Federal Resource Center.

What Illinois hasn't decided yet

• Medical frailty. Module 6 says Illinois "is considering several approaches to medical frailty code lists." For people the data can't place, HFS will rely on self-attestation.
• When the screener opens. The member notice and FAQ say "late 2026" and that HFS will announce when the screener and form are ready. Module 6, dated September 15, says exemption requests through the screener go live September 18, 2026, while Medicaid work requirement information won't appear in Manage My Case until January 1, 2027. Check ABE before telling patients it's open.
• The first look-back window. Module 6 says the first 2027 redetermination may look back as far as 12 months. The Phase 2 toolkit says one month "during the six-month period before your redetermination." The FAQ says "at least one month since your last redetermination."
• Verification after 2027. HFS describes self-attestation as its 2027 policy and hasn't said what follows.

Frequently asked questions

Do parents on Illinois Medicaid have to meet work requirements?

Usually not. HFS says most parents and caretaker relatives are in Family Health Plans, not the ACA Adult group. ACA Adults caring for a child under 14 or a person with a disability can claim an exemption.

Does a patient exempt from work requirements still renew every six months?

Yes. Module 3 says an ACA Adult exempt from work requirements is not exempt from six-month redeterminations.

Can someone who loses coverage reapply right away?

Yes. Module 6 says there's no waiting period, though ABE accepts one new application per person per month. If the denial was a mistake, file an appeal instead of reapplying.
