Transferring Medicaid from Oregon to Illinois
The short answer is no. Medicaid eligibility is decided by the state you live in, so leaving Oregon closes that coverage. Your move to Illinois means qualifying again under Illinois income rules, through Illinois Department of Healthcare and Family Services (HFS). Apply immediately — there is no new-resident waiting period.
Both states cover adults under expansion rules at 138% of the federal poverty level, so if you qualified on income in Oregon, you will likely qualify in Illinois 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 Oregon Health Authority you are leaving
Report a permanent change of mailing address or residence within 10 days of the change — online at ONE.Oregon.gov, by phone at 800-699-9075, or by mailing/faxing the Address Change Form (temporary trips out of state do not need to be reported).

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 Illinois Department of Healthcare and Family Services (HFS) 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 Oregon Medicaid in Illinois while I wait?
Generally no. Oregon Medicaid only pays providers for Oregon residents, and out-of-state care is limited to emergencies. Once you live in Illinois, you need Illinois coverage — apply immediately and ask about retroactive coverage for bills in the gap.
Is there a waiting period for Medicaid in Illinois?
No. States cannot impose a minimum-residency waiting period. You qualify (or not) on Illinois'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 Oregon case effective your move month.
Where do I actually apply in Illinois?
Through Illinois Department of Healthcare and Family Services (HFS) (online application linked above). Official Medicaid pages for both states are cited at the bottom of this page.
