Transferring Medicaid from Vermont to Montana
The short answer is no. Medicaid eligibility is decided by the state you live in, so leaving Vermont closes that coverage. Your move to Montana means qualifying again under Montana income rules, through Montana Department of Public Health and Human Services (DPHHS). Apply immediately — there is no new-resident waiting period.
Both states cover adults under expansion rules at 138% of the federal poverty level, so if you qualified on income in Vermont, you will likely qualify in Montana 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 Department of Vermont Health Access 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.

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 Vermont Medicaid in Montana while I wait?
Generally no. Vermont Medicaid only pays providers for Vermont 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 Vermont 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.
