Transferring Medicaid from South Dakota to South Carolina
No — Medicaid does not move with you. Your South Dakota coverage ends when you stop being a South Dakota resident, and you apply again with Healthy Connections after you arrive. There is no residency waiting period, and coverage can reach back to your application date.
Warning: South Carolina has not adopted Medicaid expansion, so adults who qualified in South Dakota under its expansion rules (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 South Dakota Department of Social Services 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.

Moving week
- 3
Time the closure to the end of your move month
Keep coverage through the month you travel. Your old state's coverage generally ends the month you stop being a resident.
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 (90 if a disability decision is needed).

Ask about retroactive coverage
Most states can pay eligible medical bills from as early as the third month before the month you apply, so ask when you apply if you had care during the gap. For applications filed on or after January 1, 2027, federal law (Public Law 119-21) shortens this to the month before the month you apply for adults in the expansion group and the second month before the month you apply for everyone else.

Can I use my South Dakota Medicaid in South Carolina while I wait?
Generally no. South Dakota Medicaid only pays providers for South Dakota 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 (90 if a disability decision is needed).
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 Dakota 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.
