Transferring Medicaid from Montana to Texas
Moving ends your Montana Medicaid — the program is state-bound. The good news: Texas lets you apply right away through Texas Health and Human Services Commission, with no waiting period for new residents. Keep the two cases from overlapping by closing Montana coverage effective the month you leave.
Warning: Texas has not adopted Medicaid expansion, so adults who qualified in Montana under its expansion rules (up to 138% of the federal poverty level) may not qualify in Texas at all. Check Texas'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 Montana Department of Public Health and Human Services (DPHHS) 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 Texas Health and Human Services Commission 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 Montana Medicaid in Texas while I wait?
Generally no. Montana Medicaid only pays providers for Montana residents, and out-of-state care is limited to emergencies. Once you live in Texas, you need Texas coverage — apply immediately and ask about retroactive coverage for bills in the gap.
Is there a waiting period for Medicaid in Texas?
No. States cannot impose a minimum-residency waiting period. You qualify (or not) on Texas'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 Montana case effective your move month.
Where do I actually apply in Texas?
Through Texas Health and Human Services Commission (online application linked above). Official Medicaid pages for both states are cited at the bottom of this page.
