Transferring Medicaid from Oregon to Idaho
No — Medicaid does not move with you. Your Oregon coverage ends when you stop being an Oregon resident, and you apply again with Idaho 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 Oregon, you will likely qualify in Idaho 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).

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 Idaho Department of Health and Welfare 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 (90 if a disability decision is needed). From January 1, 2027 (earlier in some states), most adults in the expansion group must also show 80 hours a month of work, school, job training, or community service, or an exemption, possibly for 1 to 3 months preceding the application.

Ask about retroactive coverage
Most states can pay eligible medical bills from as early as the third month before the month you apply, so ask when you apply if you had care during the gap. For applications filed on or after January 1, 2027, federal law (Public Law 119-21) shortens this to the month before the month you apply for adults in the expansion group and the second month before the month you apply for everyone else.

Can I use my Oregon Medicaid in Idaho 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 Idaho, you need Idaho coverage — apply immediately and ask about retroactive coverage for bills in the gap.
Is there a waiting period for Medicaid in Idaho?
No. States cannot impose a minimum-residency waiting period. You qualify (or not) on Idaho's income and category rules from the day you become a resident. The application itself takes up to 45 days (90 if a disability decision is needed).
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 Idaho?
Through Idaho Department of Health and Welfare (online application linked above). Official Medicaid pages for both states are cited at the bottom of this page.
