Kelso, WA Medicare Advantage Changes for 2027

Kelso is the Cowlitz County seat, sitting on Interstate 5 where the Cowlitz, Coweeman and Columbia rivers meet, 48 miles north of Portland and 125 miles south of Seattle (City of Kelso). That location matters: if you see doctors in Longview, Vancouver or Portland, a plan change that looks small on paper can cut you off from one of them. If your Medicare Advantage plan sent a letter saying it won't be back in 2027, here is how I would work through it.

Example: how a Kelso couple might handle the letter

Example (hypothetical, for illustration only): Pat and Lee live in Kelso. Both are 71. They have been in the same Medicare Advantage plan for six years, and in early October each got a letter saying the plan ends December 31, 2026 in Cowlitz County. Pat sees a heart doctor in Portland twice a year. Lee takes four prescriptions.

Week one: paperwork. They put both letters, with the postmarked envelopes, in a folder. If either applies for a Medicare Supplement (Medigap) policy, the insurer can ask for proof that the old plan ended.
Week two: the provider list. They write down every doctor, the hospital they'd use, and their pharmacy. Pat's Portland cardiologist goes at the top, because that is the provider most likely to fall outside a local network.
Week three: compare two paths. On Medicare Plan Finder they enter Lee's four drugs and the pharmacy and look at Medicare Advantage plans offered for their ZIP code, checking whether the Portland doctor is in each network. Then they price the other path: Original Medicare, a stand-alone Part D drug plan, and a Medigap policy.
November: decide. They don't have to pick the same thing. Pat might lean toward Original Medicare with Medigap because the Portland visits work anywhere Medicare is accepted. Lee might be happy with another Medicare Advantage plan if the drugs and doctors check out.
Before December 31: enroll. Anything chosen by then starts January 1, 2027, so neither has a day without coverage.

Your details will differ. The order of work is what carries over: letter, list, compare, decide, done before New Year's Eve.

Kelso and Cowlitz County, side by side

	Kelso	Cowlitz County
Population	12,880 (OFM, April 2026)	114,900 (OFM, April 2026)
Age 65 and older	about 2,200, roughly 17% (ACS 2020–2024)	25,298, about 22% (OFM 2025)
People with Medicare	not published for cities	29,288
In Medicare Advantage and other health plans	not published for cities	67.6%
Hospital listed by WA DOH	none inside the city	one, in Longview

Sources: WA OFM; U.S. Census ACS 2020–2024 5-year (city 65+ estimate has a margin of about ±374); CMS counts, July 2026 (county level); WA DOH 2025 hospital list.

CMS publishes Medicare enrollment by county, not city, so the closest read on Kelso is the county figure: about two of every three Cowlitz enrollees were in Medicare Advantage and other health plans in July 2026, far above the 49.7% state figure. Kelso skews a bit younger than the county as a whole. CMS doesn't publish how many people got non-renewal letters, so the county share is background, not a count.

No hospital sits inside Kelso's city limits on the state list. The county's one listed hospital is in Longview. Whatever you choose, confirm it works there, and at whatever Portland or Vancouver facility you would use for specialty care.

The Medigap door, and when it closes

Because your plan is the one leaving, you hold a right you would not normally have: you can buy certain Medigap policies without answering health questions. Washington's law, RCW 48.66.055, is broader than the federal floor. If you first qualified for Medicare before 2020 you can choose Plans A through F (including high-deductible F), K or L; if you first qualified on or after January 1, 2020, Plans A, B, D, G (including high-deductible G), K or L. The insurer must take you, cover pre-existing conditions and not charge more for your health.

Timing: OIC tells people to apply no earlier than November 1. Apply by December 31 and the policy can start January 1. The right lasts until 63 days after your plan ends, March 4, 2027. Join another Medicare Advantage plan instead, and you don't use it; after March 4 it's gone. That is the trade-off I'd think about longest, especially if you have a doctor across the river in Oregon.

The rest of the calendar

Your old plan covers you through December 31, 2026. A plan-ending special enrollment period runs December 8, 2026 through February 28, 2027; choices in January begin February 1 and choices in February begin March 1. If you choose nothing, Medicare places you in Original Medicare on January 1 with no drug plan (CMS assigns one to people with Extra Help). A gap in drug coverage of 63 days or longer can trigger the Part D late penalty, which stays on your premium for as long as you have Medicare drug coverage. The Washington statewide page on discontinued Medicare plans has the full timeline.

Your own plan letter sets your dates, and federal Medicare law plus Washington's insurance code set the rules; before you sign anything, run it past 1-800-MEDICARE, SHIBA or a licensed agent.

Kelso questions we hear

Is there a hospital in Kelso?

Not on the Washington Department of Health's 2025 list. The county's one listed hospital is in Longview, so check any new plan against it and against any Portland or Vancouver specialists you see.

Can a Kelso resident keep a Portland doctor in 2027?

Under Original Medicare, yes, if the doctor accepts Medicare. Under a Medicare Advantage plan, only if the doctor is in that plan's 2027 network, so look it up by name first.

What is the last day to buy a Medigap policy without health questions after my plan ends?

March 4, 2027, which is 63 days after a December 31, 2026 plan end. OIC says to apply no earlier than November 1; applying by December 31 lets the policy start January 1.

Does Kelso have its own Medicare enrollment numbers?

No. CMS reports by county. For Cowlitz County, CMS counts for July 2026 show 29,288 people on Medicare, 67.6% of them in Medicare Advantage and other health plans.
