Ellensburg is a college town, and the numbers show it. The Census Bureau's 2020–2024 survey puts about 2,100 of its roughly 21,000 residents at 65 or older, near 10%, while OFM counts about 21% of Kittitas County as a whole in that age group. That doesn't make a Medicare plan letter any less urgent if you're one of them. Your Medicare Advantage plan pays through December 31, 2026; here is how I would use the time.
Ellensburg and Kittitas County at a glance
| Ellensburg | Kittitas County | |
|---|---|---|
| Population | 21,500 (OFM, April 2026) | 49,250 (OFM, April 2026) |
| Age 65+ | about 2,100, near 10% (ACS 2020–2024, ±318) | 10,128, about 21% (OFM 2025) |
| People with Medicare | no city count | 10,860 (CMS counts, July 2026) |
| Medicare Advantage and other health plans | no city count | 28.1% |
| Original Medicare | no city count | 71.9% |
| Hospital (WA DOH) | Kittitas Valley Healthcare, 603 S. Chestnut | same; the county's only listed hospital |
CMS reports Medicare enrollment by county only. ACS city figures are survey estimates with the margin shown.
Two things follow. Original Medicare is the more common setup in this county, about 7 in 10 people on Medicare, so it is a well-understood option here, though that alone doesn't make it right for you. And because the one listed hospital in the county is here in town, the first network question for any Medicare Advantage plan is simple: is Kittitas Valley Healthcare in it for 2027?

A note for public-sector retirees
Ellensburg is home to Central Washington University, a state school. If your Medicare coverage comes through the Public Employees Benefits Board, your choices are made through PEBB, not through Medicare's Plan Finder. OIC tells PEBB members to contact the Health Care Authority directly. PEBB's retiree open enrollment runs October 26 through November 23, 2026, with changes effective January 1, 2027. Before you leave PEBB coverage for an individual plan, ask whether you can ever come back.
The two paths, briefly
Join another Medicare Advantage plan available in Kittitas County. Check Kittitas Valley Healthcare, your doctors and your pharmacy by name, then run your drugs through Medicare Plan Finder. Remember the trade: a network in exchange for a yearly out-of-pocket limit on covered services.
Or move to Original Medicare, add a stand-alone Part D plan, and decide on Medigap. A plan leaving the area gives you the right to buy certain Medigap plans with no health questions under RCW 48.66.055. That right is time-limited and you only use it by going to Original Medicare. If you pass on it and want Medigap later, expect medical underwriting. The Washington guide for people whose Medicare plan is being discontinued has the plan letters and Part D limits.
If you do nothing at all, Medicare puts you in Original Medicare on January 1 without drug coverage, unless you have Extra Help, in which case CMS reassigns you to a drug plan. A gap of 63 days or more can mean a Part D late penalty, added for as long as you have Medicare drug coverage.

Who to ask
- SHIBA statewide line, 800-562-6900, weekdays 8:30–4:30. The local sponsor, Kittitas County Health Network on Dolarway Road, showed "Currently not accepting appointments" on OIC's site on October 26, 2026, with a pointer to 1-800-MEDICARE.

What controls your case is federal Medicare law, Washington insurance law and the dates in your own plan notice; check with 1-800-MEDICARE, SHIBA or a licensed agent before making the switch.
