Transferring Medicaid from Washington to Oklahoma
Your coverage does not follow the moving truck. Washington Medicaid ends when residency ends, and Oklahoma requires a fresh application with Oklahoma Health Care Authority. Time the old case to close at the end of your move month, then file in Oklahoma right away to shrink the gap.
Both states cover adults under expansion rules at 138% of the federal poverty level, so if you qualified on income in Washington, you will likely qualify in Oklahoma 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 Washington State Health Care Authority you are leaving
Use Washington Healthplanfinder's 'Update my income or address/report change' function (linked from the HCA Apple Health pages) to report a move.

Moving week

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