Transferring Medicaid from Mississippi to Idaho
You cannot carry Mississippi Medicaid into Idaho. Each state runs its own program, so the sequence is: close the Mississippi case at the end of your move month, then apply with Idaho Medicaid immediately. New residents qualify on income, not on time lived in the state.
Eligibility usually gets easier in this direction: Idaho has adopted Medicaid expansion (adults up to 138% of the federal poverty level), while Mississippi has not — many adults who were denied in Mississippi qualify in Idaho.

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