Transferring Medicaid from California to Idaho
Moving ends your California Medicaid — the program is state-bound. The good news: Idaho lets you apply right away through Idaho Department of Health and Welfare, with no waiting period for new residents. Keep the two cases from overlapping by closing California coverage effective the month you leave.
Both states cover adults under expansion rules at 138% of the federal poverty level, so if you qualified on income in California, 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 California Department of Health Care Services you are leaving
Report your move to your county Medi-Cal office within 10 days; ask for your case to be closed effective the end of the month you leave.

Time the closure to the end of your move month

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.

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 California Medicaid in Idaho while I wait?
Generally no. California Medicaid only pays providers for California 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.
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 California 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.
