Transferring Medicaid from Idaho to South Carolina
Your coverage does not follow the moving truck. Idaho Medicaid ends when residency ends, and South Carolina requires a fresh application with South Carolina Department of Health and Human Services. Time the old case to close at the end of your move month, then file in South Carolina right away to shrink the gap.
Warning: South Carolina has not adopted Medicaid expansion, so adults who qualified in Idaho on income alone (up to 138% of the federal poverty level) may not qualify in South Carolina at all. Check South Carolina's categories before you move, and look at HealthCare.gov marketplace coverage as the fallback.

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 Idaho Department of Health and Welfare you are leaving
Report your move and ask for your case to be closed effective the end of the month you leave. Medicaid cannot cover you in two states at once.

After you arrive
- 4
Apply with South Carolina Department of Health and Human Services 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 Idaho Medicaid in South Carolina while I wait?
Generally no. Idaho Medicaid only pays providers for Idaho residents, and out-of-state care is limited to emergencies. Once you live in South Carolina, you need South Carolina coverage — apply immediately and ask about retroactive coverage for bills in the gap.
Is there a waiting period for Medicaid in South Carolina?
No. States cannot impose a minimum-residency waiting period. You qualify (or not) on South Carolina'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 Idaho case effective your move month.
Where do I actually apply in South Carolina?
Through South Carolina Department of Health and Human Services (online application linked above). Official Medicaid pages for both states are cited at the bottom of this page.
