Medicare provides health insurance to over 65 million Americans, including 1.5 million in the state of Washington. Benefits are generally open to seniors aged 65 and over, as well as certain qualifying younger adults. Most beneficiaries enroll in Original Medicare at age 65, which splits coverage between hospital and inpatient care (Part A), outpatient visits and medical equipment (Part B) and a prescription drug benefit (Part D). Since 2003, Medicare enrollees have had an alternative to Original Medicare, known as Part C or Medicare Advantage.

Medicare Advantage Plans are issued by private insurance companies that are licensed to offer care plans in individual states. By law, these plans must provide the same level of coverage as Original Medicare Parts A and B, but they’re typically combined into a single package with one monthly premium. Most Medicare Advantage Plans go beyond minimal coverage to include prescription drug benefits, dental and vision care and several other benefits not included in traditional plans, such as hearing aids and planning services.

These plans are attractive to many Washington seniors for the simplicity of having a single bill each month, which may be as low as $0, and expanded coverage options. They also tend to be more flexible than Original Medicare benefits and may be offered as HMOs, PPOs or as specialty benefits plans for people with unique care needs. In 2023, 45% of Medicare enrollees in Washington have signed up to get their Medicare benefits through a Part C plan, which is close to the 48% national participation rate. This represents a year-over-year growth of nearly 8% from 2022, a time when national participation only rose by 7%.

This guide lists the top providers for Medicare Advantage in Washington, along with price data and Medicare star ratings. Enrollment figures are also given for the most popular care plans. The goal is to help seniors and their families find a Medicare Advantage Plan that works for them and get a head start on planning for great health coverage over age 65.

How Medicare Advantage Plans Work in Washington

Before choosing an Advantage plan, it’s important to know what makes Medicare Advantage different than Original Medicare and how to qualify. Insurance companies offer multiple plans and plan types. There are four types of plans available in Washington: health maintenance organization (HMO), preferred provider organization (PPO), private fee-for-service (PFFS), and special needs plan (SNP), and each plan has its own rules regarding eligibility, network providers, how to see a specialist and what prescription medications are covered. The table below breaks down the four types of Medicare Advantage plans.

Eligibility for Medicare Advantage in Washington

Before seniors can enroll in an Advantage plan, they must first be enrolled in Medicare Parts A and B, live in the plan’s service area and meet the other eligibility requirements for the plan they’ve chosen. Medicare Advantage is available for retirees over the age of 65 or adults with disabilities that allow them to receive Medicare coverage. All beneficiaries need to be lawful citizens or residents of the United States.

Medicare has limited enrollment periods, and there could be penalties for not enrolling during the initial period. Special enrollment periods are available for people who experience specific life events that allow them to enroll free of penalties. Seniors enrolled in Medicare may change their coverage during each enrollment period. See the following list for more information on enrollment periods and timing. 

  • Initial Coverage Election Period: This is the initial 7-month period, coinciding with one’s 65th birthday, during which everyone is eligible to enroll in a Medicare Advantage plan.
  • Annual Election Period (AEP): Also referred to as the Open Enrollment Period, this the time of year when anyone over 65 can enroll in Medicare Advantage for the first time or change to a new plan.
  • Medicare Advantage Open Enrollment Period: During this period, those who are already enrolled in Medicare Advantage can switch to a different plan or switch back to Original Medicare.
