Transferring Medicaid from South Carolina to Montana
Medicaid is not portable. The South Carolina program stops covering you when you move, and Montana Medicaid starts only after you apply and qualify under Montana's rules. Apply in your first week; ask about retroactive coverage if you had medical bills during the gap.
Eligibility usually gets easier in this direction: Montana 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 Montana.

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 Montana 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 Montana, you need Montana coverage — apply immediately and ask about retroactive coverage for bills in the gap.
Is there a waiting period for Medicaid in Montana?
No. States cannot impose a minimum-residency waiting period. You qualify (or not) on Montana'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 Montana?
Through Montana Department of Public Health and Human Services (DPHHS) (online application linked above). Official Medicaid pages for both states are cited at the bottom of this page.
