Washington State has earned a reputation for progressive healthcare policy, and its state-run marketplace reflects that commitment to expanding access. Health insurance in Washington is available through Wahealthplanfinder, the state-based exchange that has been connecting residents with qualified health plans and Apple Health (Medicaid) since 2013. With over 200,000 residents enrolled in marketplace plans and more than 2 million covered through Apple Health, the Evergreen State provides a range of pathways to coverage. Here is what you need to know about choosing and enrolling in a plan.
Wahealthplanfinder: Washington’s State Marketplace
Washington operates its own health insurance exchange through Wahealthplanfinder, managed by the Washington Health Benefit Exchange. Unlike states that rely on the federal Healthcare.gov platform, Washington controls its own enrollment system, outreach, and customer support infrastructure. This gives the state flexibility to extend enrollment periods, create tailored outreach campaigns, and offer unique programs.
The marketplace offers Bronze, Silver, Gold, and Platinum tier plans, along with catastrophic plans for eligible young adults. Washington has also been at the forefront of standardized plan design, meaning that plans within each metal tier share similar cost-sharing structures, making it easier for consumers to compare based on network, carrier reputation, and extra benefits rather than puzzling through different deductible and copay combinations.
Washington made national news by introducing a public option called Cascade Care. These plans, available through Wahealthplanfinder, are offered by private insurers but must meet state-set requirements for affordability and provider access. Cascade Care plans are designed to bring down premiums, particularly in rural areas where competition among insurers has traditionally been limited.
Major Insurers in Washington
Several carriers participate in the Washington marketplace, though availability depends on your county. Premera Blue Cross and Regence BlueShield are two of the largest, offering plans across much of the state. Kaiser Permanente provides coverage in parts of western Washington, known for its integrated care model. Molina Healthcare, Community Health Plan of Washington, Coordinated Care, and LifeWise Health Plan of Washington round out the marketplace options.
In the Seattle metro area, residents often have five or more carriers to choose from, creating strong price competition. Rural eastern Washington and some smaller counties may have only one or two options, which is partly why the state introduced Cascade Care public option plans to improve affordability in those areas.
Network differences matter significantly in Washington. Kaiser Permanente operates its own hospitals and clinics, meaning you must generally use Kaiser facilities. Other carriers contract with independent hospitals and physician groups, so checking whether your preferred providers participate in a plan’s network is essential before enrolling.
Costs, Premiums, and Subsidies
The cost of health insurance washington residents face varies by age, location, and plan tier. According to KFF, the average benchmark Silver plan premium in Washington before subsidies is roughly $450 to $575 per month for a 40-year-old, depending on the rating area. Western Washington counties, particularly around Seattle, tend to have more competitive pricing due to greater insurer competition.
Premium tax credits are available to reduce costs for households with qualifying incomes. Washington residents who earn between 138% and 400% of the federal poverty level — and in many cases above 400% thanks to enhanced subsidies — may receive significant financial help. The state estimates that most marketplace enrollees pay less than the full premium, with many paying under $100 per month after credits are applied.
Washington also offers a state-funded premium assistance program for certain income levels, further reducing costs beyond what federal subsidies provide.

How to Enroll
Open Enrollment for health insurance in Washington through Wahealthplanfinder typically runs from November 1 through January 15, though the state has occasionally extended deadlines. During this period, anyone can apply for new coverage, change plans, or renew existing coverage.
Visit Wahealthplanfinder.org to create an account and begin your application. You will need income documentation, Social Security numbers for household members, and information about any employer coverage available. The system determines your eligibility for premium tax credits, cost-sharing reductions, and Apple Health before showing plan options.
Outside of open enrollment, Special Enrollment Periods are available for qualifying life events like losing other coverage, moving to Washington, marriage, or the birth of a child. The state also maintains a network of brokers and navigators called enrollment assisters who offer free help in multiple languages. Those who are self-employed will find the marketplace especially useful, as it is designed to serve individuals without employer coverage.
Apple Health: Medicaid and CHIP in Washington
Washington expanded Medicaid under the ACA, and its program — called Apple Health — covers adults with incomes up to 138% of the federal poverty level as well as children in families with higher incomes. Apple Health is administered by the Washington Health Care Authority and provides comprehensive coverage including medical, dental, vision, mental health, and substance use disorder services.
Children may qualify for Apple Health with household incomes up to 312% of the federal poverty level, and pregnant individuals qualify at even higher income thresholds. The program has no premiums and minimal cost-sharing for most enrollees, making it one of the more generous Medicaid programs nationally.
You can apply for Apple Health directly through Wahealthplanfinder at any time of year — there is no limited enrollment period for Medicaid. The marketplace application automatically screens for Apple Health eligibility. You can also apply through the Health Care Authority or at a local Community Service Office.
Cascade Care and the Public Option
Washington’s Cascade Care initiative represents one of the first state-level public option experiments in the country. These plans are sold on Wahealthplanfinder alongside standard marketplace plans, but they must meet additional state requirements for affordability. Insurers offering Cascade Care plans must cap premiums at a percentage of the benchmark Silver plan cost and must contract with a sufficient network of providers.
The goal is to bring down premiums in areas where limited competition has kept prices high. In practice, Cascade Care plans have been most impactful in rural counties where one or two carriers previously dominated the market. The plans are available across all metal tiers and are identifiable on Wahealthplanfinder by a Cascade Care label, making them easy to spot while shopping.
