Transferring Medicaid from New Hampshire to Washington
Plan on a close-and-reapply. New Hampshire Medicaid only works while you live in New Hampshire; once you land in Washington, your application goes to Washington State Health Care Authority. File it immediately after arriving, because processing takes time and coverage ties to the application date.
Both states cover adults under expansion rules at 138% of the federal poverty level, so if you qualified on income in New Hampshire, you will likely qualify in Washington 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 Hampshire Department of Health and Human 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.

Time the closure to the end of your move month

After you arrive
- 4
Apply with Washington State 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 New Hampshire Medicaid in Washington while I wait?
Generally no. New Hampshire Medicaid only pays providers for New Hampshire residents, and out-of-state care is limited to emergencies. Once you live in Washington, you need Washington coverage — apply immediately and ask about retroactive coverage for bills in the gap.
Is there a waiting period for Medicaid in Washington?
No. States cannot impose a minimum-residency waiting period. You qualify (or not) on Washington'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 Hampshire case effective your move month.
Where do I actually apply in Washington?
Through Washington State Health Care Authority (online application linked above). Official Medicaid pages for both states are cited at the bottom of this page.
