How it works here
ACA Marketplace plans, explained for Washington.
Washington residents buy ACA Marketplace plans through Washington Healthplanfinder. These are comprehensive plans that cover the ten essential health benefits, cannot deny you for a pre-existing condition, and are the only plans eligible for income-based premium tax credits.
Because Washington runs a state-based marketplace, you enroll at Washington Healthplanfinder. Plans and prices are set at the county level across Washington's 39 counties, so two neighbors in different counties can see different options.
Washington expanded Medicaid, so if your income is low you may qualify for Medicaid instead of a subsidized plan — the Marketplace will tell you when you apply.
Washington Healthplanfinder is the state-based marketplace for Washington residents.
Washington expanded Medicaid (Apple Health), and applications commonly screen public coverage alongside subsidized private plans.
King County and other Puget Sound counties often differ from eastern Washington counties in issuer competition and specialist access.
