Transferring Medicaid from Washington to Delaware
No — Medicaid does not move with you. Your Washington coverage ends when you stop being a Washington resident, and you apply again with Delaware Medicaid after you arrive. There is no residency waiting period, and coverage can reach back to your application date.
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 Delaware too.

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 Delaware 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 Delaware, you need Delaware coverage — apply immediately and ask about retroactive coverage for bills in the gap.
Is there a waiting period for Medicaid in Delaware?
No. States cannot impose a minimum-residency waiting period. You qualify (or not) on Delaware'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 Delaware?
Through Delaware Health and Social Services, Division of Medicaid and Medical Assistance (online application linked above). Official Medicaid pages for both states are cited at the bottom of this page.
