Questions
Good questions, short answers.

Washington runs its own exchange, Washington Healthplanfinder, which sets its own dates. Most exchanges open Nov 1, 2026 and close Jan 15, 2027 for 2027 coverage; confirm the exact dates with Washington Healthplanfinder. A qualifying life event (a move, a new baby, losing other coverage) opens a Special Enrollment Period at other times of year.
Where do I buy health insurance in Washington?
Washington residents enroll through Washington Healthplanfinder. You can also buy off-Marketplace plans, health sharing, or supplemental coverage directly.
Is Medicaid available in Washington?
Yes. Because Washington expanded Medicaid, adults under a certain income may qualify regardless of family status. Eligibility is based on income and household size.
How much does health insurance cost in Washington?
It depends on your age, county, plan tier, and — most importantly — whether you qualify for a subsidy. Many Washington enrollees pay well under $100/month after ACA premium tax credits. Use our calculators to estimate your cost.
