Transferring Medicaid from New York to South Dakota
Think of it as two separate programs: New York Medicaid ends with your residency, and South Dakota Medicaid begins with a new application. Nothing carries over automatically. Submit the South Dakota application as soon as you have an address there.
Both states cover adults under expansion rules at 138% of the federal poverty level, so if you qualified on income in New York, you will likely qualify in South Dakota too.

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