What the numbers mean
- More plans isn't automatically better. What matters is whether a plan's network includes your doctors and hospital, and whether its formulary covers your drugs.
- Counts don't show costs or benefits. Medicare Advantage plans may offer extra benefits such as dental, vision, hearing or fitness. Extra benefits vary by plan and county, may have limits and costs, and not every plan offers them. Check a plan's Summary of Benefits or Evidence of Coverage.
- Many Oregonians already use Medicare Advantage. In July 2026, 523,528 of Oregon's 973,880 people with Medicare were in Medicare Advantage or other health plans, according to CMS.
Changes for 2027
Six companies stop offering Medicare Advantage plans in some Oregon counties for 2027. If your plan is ending, you'll get a non-renewal letter and have a Special Enrollment Period through February 28, 2027; choose a new plan by December 31, 2026, to avoid a gap. See plans ending in 2027.
Open Enrollment runs through December 7, 2026. You can see plans for your ZIP code at PlanMatch or Medicare.gov's Plan Finder, or request a call from a licensed insurance agent to compare plans from the companies they work with.

Frequently asked questions
Why does my county have fewer plans than the statewide number?
Each plan is approved for specific counties. The statewide number counts every plan offered anywhere in Oregon once, so no county has all of them.
What is a special needs plan?
A Medicare Advantage plan only for people who have both Medicare and the Oregon Health Plan, live in a nursing home, or have certain chronic conditions. They are counted separately because not everyone can join.
How many standalone Part D plans are in Oregon for 2027?
8 standalone Part D plans from 4 companies, available statewide. Oregon and Washington share Part D region 30.
