Transferring Medicaid from Wyoming to Washington
Plan on a close-and-reapply. Wyoming Medicaid only works while you live in Wyoming; 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.
Eligibility usually gets easier in this direction: Washington has adopted Medicaid expansion (adults up to 138% of the federal poverty level), while Wyoming has not — many adults who were denied in Wyoming qualify in Washington.

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 Wyoming Medicaid in Washington while I wait?
Generally no. Wyoming Medicaid only pays providers for Wyoming 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 Wyoming 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.
