Medicare Advantage plans in Washington State

A Medicare Advantage plan (also called Part C) is an all-in-one alternative to Original Medicare, offered by private insurers that Medicare approves and pays. You still have Medicare, but the plan administers your Part A and Part B coverage and almost always folds in Part D drug coverage too. Which companies sell in your county, and which hospitals sit inside each plan’s network, changes every year — and in Washington State that second question usually settles the choice.

What’s usually included

• Hospital and medical coverage (your Part A and Part B benefits).
• Prescription drug coverage in most plans — so you don’t buy a separate Part D plan.
• Extras Original Medicare doesn’t cover, which can include dental, vision, hearing, fitness benefits, and an annual out-of-pocket maximum that caps what you spend on covered care.

The trade-off: networks, system by system

Advantage plans use provider networks (HMO or PPO) and are sold by county. That is the single most important thing to check before you enroll: whether your doctors and your hospital are in the plan’s network, and whether your medications are on its drug list. Washington’s big systems each contract on their own terms — UW Medicine (Harborview, UW Medical Center, Valley Medical Center), Providence Swedish, MultiCare (Tacoma, Puyallup, Auburn, Spokane, Yakima), Virginia Mason Franciscan Health, EvergreenHealth, Overlake, PeaceHealth (Bellingham, Vancouver, Longview), Confluence Health in Wenatchee, Kadlec in the Tri-Cities and Providence Sacred Heart in Spokane. Kaiser Permanente Washington is different again: it is both an insurer and a care system, and its Advantage plans are built around its own medical centers.

Two Washingtons

West of the Cascades — King, Pierce, Snohomish, Thurston, Clark, Whatcom, Kitsap — the Advantage menu is deep and the networks usually include most of the big systems, so the comparison is about extras, drug costs and which system your doctors belong to. East of the passes and along the coast the menu is short, several counties lean on a single public hospital district, and a specialist may mean a drive to Spokane, Yakima, the Tri-Cities or over the mountains to Seattle. Out there, a $0-premium plan with a network that stops at the county line can be a poor bargain, and Original Medicare with a Medigap policy is often the practical answer.

If your plan left your county

A non-renewal notice is not just bad news; it opens doors. You get a Special Enrollment Period that runs past the normal deadlines, and because the plan left you involuntarily, federal rules give most people a guaranteed-issue right to buy a Medigap policy without medical underwriting, generally for 63 days after your coverage ends. Once you hold that Medigap policy, Washington’s year-round switching rule lets you move between Medigap plans later without health questions; it does not, however, get you into Medigap from an Advantage plan, so use the federal window when it comes.

Who Medicare Advantage tends to suit

People who want predictable, lower upfront costs and value bundled extras, who are comfortable using a plan network, and who live where the menu is deep. If you spend winters in Arizona or summers on the Peninsula, see specialists outside the network, or want to use any provider nationwide, compare it against a Medigap policy. Military retirees with TRICARE For Life have their own calculation; see Veterans.

There are also specialized Advantage plans for specific situations: Chronic Special Needs Plans (C-SNPs), Institutional SNPs (I-SNPs), and Dual Special Needs Plans for people with both Medicare and Apple Health.
