A note on geography: Medicare Advantage plans are approved county by county. A plan counted once in this statewide view may or may not be available in the county where you actually live.

Which Kaiser Permanente Medicare Advantage plans reach the most Oregon counties in 2027?

Three of Kaiser Permanente's 2027 Oregon plans share the widest county reach, each offered in 9 counties: Kaiser Permanente Senior Advantage Enhanced (HMO-POS), Kaiser Permanente Senior Advantage Standard (HMO-POS) and Kaiser Permanente Senior Advantage Value (HMO-POS). The fourth plan, Kaiser Permanente Senior Advantage Value Lane (HMO-POS), is offered in 1 county.

All four plan names, plan types and county counts appear in the plan table on this page. The important thing to carry forward is that "offered in Oregon" and "offered in your county" are not the same statement — a plan listed above may not be sold where you live, and you should confirm availability by county before making any decisions.

What is new or not returning from Kaiser Permanente in Oregon for 2027?

Nothing is changing on either side of the ledger: Kaiser Permanente has 0 new Medicare Advantage plans for 2027 in Oregon and 0 plans that are not returning from 2026. In other words, the Kaiser Permanente lineup carries over from 2026 to 2027 at the statewide level.

Even when the lineup is stable, the details inside a plan — the drug formulary, the provider directory, the cost-sharing structure, and the extra benefits — can shift from one year to the next. Current Kaiser Permanente members should still read the Annual Notice of Change (ANOC) that the plan mails each fall and compare it to the 2027 Evidence of Coverage.

How do I check whether a Kaiser Permanente plan is offered in my Oregon county and covers my doctors and prescriptions?

The most reliable way to check county availability, doctors and drugs for a 2027 Kaiser Permanente plan in Oregon is to use the Medicare Plan Finder at Medicare.gov or call 1-800-MEDICARE (TTY 1-877-486-2048), available 24 hours a day, 7 days a week. Enter your ZIP code and county, then your prescriptions and pharmacies, and the tool will show which plans are available at your address.

A short checklist that works for any plan you are considering:

• Confirm the plan is offered in your specific Oregon county for 2027, not just somewhere in the state.
• Search the plan's provider directory for the doctors, clinics and hospitals you want to keep using.
• Enter each prescription into the plan's 2027 formulary to see tier, restrictions and preferred pharmacies.
• Read the plan's Evidence of Coverage for the full rules on referrals, prior authorization and out-of-network care.

Because the four Kaiser Permanente plans are HMO-POS products, how out-of-network care is handled is one of the details worth confirming in writing before you enroll.

What should Oregon Medicare beneficiaries do before December 7, 2026?

Before December 7, 2026, Oregon beneficiaries should review their current coverage and compare it to the plans available in their county for 2027, because that is the last day of the Annual Enrollment Period. Any Medicare Advantage or Part D choice you make between October 15 and December 7, 2026 takes effect January 1, 2027.

A workable sequence:

1. Read your current plan's Annual Notice of Change when it arrives in the fall of 2026. 2. Make a short list of must-keep doctors, hospitals and prescriptions. 3. Use the Medicare Plan Finder at Medicare.gov to compare the 2027 options in your county — Kaiser Permanente and the 13 other carriers offering plans in Oregon. 4. If you decide to switch, enroll on or before December 7, 2026.

If you are satisfied with your current plan and it is returning for 2027, you generally do not need to do anything to stay enrolled.
