A plan can be listed because it was renumbered or replaced, not only because a company is leaving the county. When the same company keeps other plans there, members are usually moved to a replacement plan. Your plan should send you a notice, and Medicare’s Annual Enrollment Period (October 15 to December 7) is when you can compare and switch. “People enrolled” is the number enrolled in that plan today (CMS hides counts of 10 or fewer).

Why your county matters for coverage
In Oregon, the health plans you can choose depend on where you live. Medicare Advantage and Part D plans are offered by service area, usually county by county, and marketplace premiums and carriers are set by area as well. Living in Washington County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Oregon SHIBA (Senior Health Insurance Benefits Assistance) gives free, unbiased counseling at 800-722-4134. Ask which plans serve Washington County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace) -- transitioning to Explore Health November 1, 2026; enter your Washington County ZIP code to see what is offered.
- Medicaid: apply through Oregon Health Plan (Oregon Health Authority).
Oregon note: Oregon is in the middle of a marketplace transition: a 2023 state law required the Oregon Health Authority to stand up its own exchange, and the new Explore Health site received federal approval and is scheduled to replace HealthCare.gov for Oregon starting November 1, 2026 -- worth double-checking which site is current if you're reading this after that date.
