More than 1.5 million people in Washington are signed up for Medicare, putting it in the top 15 states for Medicare beneficiaries.
Medicare is the federal health insurance program for people 65 and older. Medicare Advantage, sold by private insurance companies, is a bundled alternative to Medicare that offers the same benefits and usually some extras, such as cost help with dental and vision coverage.
Medicare Advantage plans offer more benefits than Original Medicare plans, and they're often cheaper than paying for Medicare and a Medicare Supplement Insurance plan, or Medigap. However, they offer less flexibility because you’ll need to get care from within the plan’s network of providers. Weigh your options to determine what plan best suits your needs.

How to choose a Medicare Advantage plan
It’s crucial to ask a few questions as you’re shopping for the right plan. Here’s a quick checklist to help you consider your options:
How much are the plan’s costs? Do you understand what the plan’s premium, deductibles, copays and/or coinsurance will be? Can you afford them?
Is your doctor in-network? If you have a preferred doctor (or doctors) or hospital, make sure they participate in the plan’s network.
Are your prescriptions covered? If you’re on medication, understand how the plan covers it. What tier are your prescription drugs on, and are there any coverage rules that apply to them?
Is there dental coverage? Does the plan offer routine coverage for vision, dental and hearing needs?
Are there extras? Does the plan offer any additional perks, such as fitness memberships, transportation benefits or meal delivery?

Medicare Advantage review methodology
The Medicare Advantage marketplace is concentrated among just a handful of companies; in many places, one insurer serves more than half of the market. NerdWallet reviewed 26 Medicare Advantage brands, with some insurers having more than one brand under their umbrella. (For example, Blue Cross Blue Shield includes the brands Anthem and Highmark.) At the national level, these reviews include nine of the 10 largest brands by enrollment. At the state level, our research includes at least one major insurer in 47 of the 49 states that offer Medicare Advantage plans, and includes the top two insurers in 35 of those states. (Alaska doesn't offer Medicare Advantage plans.) We also look at online search volume to identify regional and other notable players in the space.
NerdWallet’s Medicare Advantage reviews are based on ratings data from the Centers for Medicare & Medicaid Services, as well as pricing, plan availability by state, plan types available, consumer experience, extra benefits offered and more. These reviews are a guide, but we encourage you to shop around and compare several plans to find the best coverage and rate for you. NerdWallet does not receive compensation for any reviews.
