Transferring Medicaid from South Carolina to Idaho
Plan on a close-and-reapply. South Carolina Medicaid only works while you live in South Carolina; once you land in Idaho, your application goes to Idaho Department of Health and Welfare. File it immediately after arriving, because processing takes time and coverage ties to the application date.
Eligibility usually gets easier in this direction: Idaho has adopted Medicaid expansion (adults up to 138% of the federal poverty level), while South Carolina has not — many adults who were denied in South Carolina qualify in Idaho.

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