Snoqualmie has its own hospital, and that changes how you should shop for 2027 coverage. Snoqualmie Valley Hospital on Frontier Avenue SE is listed by CMS as a critical access hospital. It's the only hospital with a Snoqualmie address in the state and federal hospital lists. So if your Medicare Advantage plan is ending, the very first question for any replacement is simple: is Snoqualmie Valley Hospital in the network, and are your valley doctors?
Start with the network, not the brochure
A Medicare Advantage plan generally asks you to use doctors and hospitals in its network for non-emergency care, and you may need a referral to see a specialist. Networks are drawn plan by plan and change every year. A plan that's fine for someone in Bellevue may not include the providers you rely on east of Issaquah.
Before you pick any 2027 Medicare Advantage plan, check these by name in its provider directory:
- Snoqualmie Valley Hospital
- Your primary care clinic
- Any specialist you see, including ones in Issaquah, Bellevue or Seattle
- The larger hospital you'd want for surgery or a serious illness
- Your pharmacy, checked against the plan's 2027 drug coverage
The other road is Original Medicare. It has no network: you can see any doctor or hospital in the U.S. that accepts Medicare, and in most cases you don't need a referral. What it lacks is a yearly cap on your out-of-pocket costs and most drug coverage, which is why people pair it with a stand-alone Part D plan and often a Medigap policy. Medicare Advantage plans do carry a yearly out-of-pocket limit for covered services. That's the real trade: network rules and a cap, or open access and filling the gaps yourself.

Snoqualmie has the smallest share of residents 65 and older of any King County city above 10,000 people. That means fewer neighbors going through this, and fewer people at the next table who have done it before. It also means many readers here are newer to Medicare. If you first became eligible on or after January 1, 2020, Medigap Plans C and F aren't available to you; D and G take their place under the guaranteed issue right.
Dates for anyone whose plan is ending
Your current plan pays through December 31, 2026. Make your choice by that day and the new coverage starts January 1. Because the plan is ending, you also have a special enrollment period from December 8, 2026 through February 28, 2027; anything chosen in January starts February 1, and in February starts March 1.
If you don't choose, you'll be in Original Medicare on January 1, 2027, with no drug plan unless you get Extra Help (CMS reassigns those members to a stand-alone Part D plan).
For the Medigap route, Washington law gives you a guaranteed issue right when your Medicare Advantage plan ends, as long as you switch to Original Medicare. OIC says apply on or after November 1. The window closes 63 days after your plan does, on March 4, 2027. The statewide guide has the plan-by-plan detail.
One practical step for the Medigap road: hold on to your plan's letter and the postmarked envelope. An insurer may ask for a copy to confirm your plan ended, and digging for it in February is no fun. If you were in your first Medicare Advantage plan for less than a year, also ask SHIBA about a "trial right," which can widen your Medigap choices.
Help in the valley
The Mt Si Senior Center at 411 Main Avenue South in North Bend lists information and referral on health insurance issues, and King County's directory says Medicare recipients of any age can use it. Hours are weekdays 9 to 4; call for an appointment.
For rides, the same listing points to Snoqualmie Valley Transportation at (425) 888-7001 for transit information and door-to-door reservations. If a new network sends you to specialists down the hill, that's worth a call before January.
Statewide, SHIBA offers free, unbiased Medicare counseling at 800-562-6900, weekdays 8:30 to 4:30. When we checked on October 26, 2026, OIC's listings for King County's local SHIBA sponsors said they weren't taking appointments and directed people to 1-800-MEDICARE (1-800-633-4227), which runs 24 hours. Medicare's Plan Finder lets you filter by your drugs and pharmacy.
Federal Medicare rules and Washington law are the backdrop for everything above; the dates in your plan's own notice are what bind you, so confirm with 1-800-MEDICARE, a SHIBA advisor or a licensed agent before choosing.
