Transferring Medicaid from Illinois to Michigan
No — Medicaid does not move with you. Your Illinois coverage ends when you stop being a Illinois resident, and you apply again with Michigan Medicaid after you arrive. There is no residency waiting period, and coverage can reach back to your application date.
Both states cover adults under expansion rules at 138% of the federal poverty level, so if you qualified on income in Illinois, you will likely qualify in Michigan too.

Your step-by-step checklist
Before you move
- 1
Gather your documents before the move
You will reapply from scratch: proof of identity, income (pay stubs or award letters), your new address, and immigration documents if applicable.
- 2
Tell Illinois Department of Healthcare and Family Services (HFS) you are leaving
HFS directs customers to manage their case — including renewals and updates such as address changes — through the ABE (Application for Benefits Eligibility) 'Manage My Case' portal; use it or your local Family Community Resource Center to update or close your case.

Moving week
- 3
Time the closure to the end of your move month
Keep coverage through the month you travel. Your old state's coverage generally ends the month you stop being a resident.
After you arrive
- 4
Apply with Michigan Department of Health and Human Services (MDHHS) as soon as you arrive
There is no waiting period based on how long you have lived there — apply immediately. Processing: up to 45 days.

Ask about retroactive coverage
Most states can cover eligible medical bills up to 3 months before your application date — ask when you apply if you had care during the gap.

Can I use my Illinois Medicaid in Michigan while I wait?
Generally no. Illinois Medicaid only pays providers for Illinois residents, and out-of-state care is limited to emergencies. Once you live in Michigan, you need Michigan coverage — apply immediately and ask about retroactive coverage for bills in the gap.
Is there a waiting period for Medicaid in Michigan?
No. States cannot impose a minimum-residency waiting period. You qualify (or not) on Michigan's income and category rules from the day you become a resident. The application itself takes up to 45 days.
Can I have Medicaid in two states at once?
No. You can only receive Medicaid from the state where you live. Keeping an old case open while opening a new one can create repayment problems — close the Illinois case effective your move month.
Where do I actually apply in Michigan?
Through Michigan Department of Health and Human Services (MDHHS) (online application linked above). Official Medicaid pages for both states are cited at the bottom of this page.
