Medicare Plan Choices in Mukilteo, WA for 2027

Around Mukilteo, shoppers often wonder how their Medicare options compare with what neighbors a few miles away are seeing. Heading into 2027, choice looks broad across the north Puget Sound metro, but the exact plan count depends on which county line you fall on. Mukilteo is in Snohomish County, where the 2026 Medicare Advantage and Part D Landscape files from the Centers for Medicare & Medicaid Services (CMS) showed a full slate of plans available to residents age 65 and older. The 2027 lineup is detailed in each plan's Annual Notice of Change (ANOC) and on the Plan Finder at Medicare.gov.

What "plan availability" really means around Mukilteo

Medicare plan availability is set by CMS at the county level, not the city level. That means every ZIP code inside Snohomish County — Mukilteo, Everett, Lynnwood, Edmonds, Bothell and the smaller communities in between — draws from the same menu of Medicare Advantage plans. If you cross into King County to the south or Island County to the west, the list changes, sometimes noticeably.

For 2026, Snohomish County residents had 71 Medicare Advantage plans to consider. That is a large field by national standards, and it reflects the fact that the Seattle–Everett metro is a competitive market where multiple national and regional insurers do business. The 2027 plan count is published in the CMS Landscape files and on Medicare.gov's Plan Finder.

How nearby areas compare

Because availability shifts at each county border, a Mukilteo resident and a relative in a neighboring county may see different plan lists even if they live 20 minutes apart. When you use the Plan Finder at medicare.gov, the tool asks for your ZIP code precisely so it can match you to the county-level menu CMS has approved.

A few things to keep in mind when you compare across the metro:

• The number of Medicare Advantage plans in a county tells you how much choice exists, not how good any single plan is.
• The number of carriers matters too. In Snohomish County, 10 carriers offered MA-PD plans for 2026, meaning shoppers could compare across several companies rather than being limited to one or two. The 2027 carrier list is on Medicare.gov's Plan Finder.
• Stand-alone Part D plans, which are used by people who stay on Original Medicare, are offered on a broader regional footprint. Availability counts for those plans are reported separately by CMS.

Star Ratings, briefly

CMS publishes Star Ratings each fall to give consumers a general sense of quality for Medicare Advantage and Part D contracts. Ratings look at things like customer service, member experience, and how well plans manage chronic conditions.

Ratings are a helpful sanity check, but they are not a shopping shortcut. A high-star contract may not fit your doctors, your prescriptions, or your budget — and a lower-rated contract may cover the specialists you already see. Use ratings as one input among several.

Program-wide rules that apply in 2027 no matter which plan you pick

Some of the biggest changes for 2027 are program-wide and apply to every Part D and MA-PD plan:

• The Part D out-of-pocket cap is $2,100 in 2026 ($2,400 in 2027). Once your covered drug spending hits that amount, you pay $0 for covered Part D drugs the rest of the year.
• The maximum Part D deductible is $615 in 2026 ($700 in 2027). Plans can charge less, but not more.
• The coverage gap ("donut hole") is gone as of 2025. Part D now has three phases: deductible, initial coverage, and catastrophic.
• The Medicare Prescription Payment Plan lets you spread your out-of-pocket drug costs across the calendar year in monthly installments instead of paying at the pharmacy counter.
• IRMAA surcharges — the income-related extra amounts for Part B and Part D — begin above $109,000 for a single filer in 2026.

Key dates for Mukilteo shoppers

• Oct. 15 – Dec. 7: Annual Enrollment Period. You can join, switch, or drop a Medicare Advantage or Part D plan for coverage that begins Jan. 1.
• Jan. 1 – March 31: Medicare Advantage Open Enrollment. If you are already in an MA plan, you can make one change during this window.
