Aetna Medicare Advantage in Oregon for 2027: 3 Plans, County by County

SALEM, Ore. — For the 2027 plan year, Aetna (which the Centers for Medicare & Medicaid Services groups as Aetna (CVS Health)) is offering three Medicare Advantage plans in Oregon, according to the CMS Medicare Advantage Landscape Source Files for CY2027. Oregonians will see those three Aetna plans alongside offerings from 13 other Medicare Advantage carriers in the state, for a statewide total of 95 plans. Because every Medicare Advantage plan is sold county by county, a plan listed statewide may or may not be available where you actually live.

What is Aetna offering across Oregon for 2027?

Aetna is offering 3 Medicare Advantage plans in Oregon for the 2027 plan year, per the CMS Landscape Source Files. Of those 3 plans, 1 is a Health Maintenance Organization (HMO) and 2 are HMO-POS (HMO with a Point-of-Service option). Two of the three plans include Medicare prescription drug coverage; one does not.

Aetna is not offering any Special Needs Plans (SNPs) in Oregon for 2027 — zero Dual Eligible SNPs (D-SNP), zero Chronic Condition SNPs (C-SNP), and zero Institutional SNPs (I-SNP). Oregonians who need an SNP would need to look at other carriers among the 13 also offering Medicare Advantage in the state.

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

Among Aetna's three Oregon plans for 2027, the widest county reach belongs to Aetna Medicare Eagle (HMO), which is offered in 7 counties. It is an HMO without drug coverage and is new for 2027.

Aetna's two remaining plans are both named Aetna Medicare Elite (HMO) and are both HMO-POS plans with drug coverage. One is offered in 5 counties and the other in 2 counties. Both were renamed for 2027 — each was previously listed as Aetna Medicare Elite (HMO-POS). The full plan-by-plan breakdown is shown in the table on this page; we are not listing every county here because that information is best confirmed against your own ZIP code on Medicare.gov.

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

For 2027, Aetna has 1 new Medicare Advantage plan in Oregon — Aetna Medicare Eagle (HMO) — and 3 plans that were available in 2026 are not returning for 2027. CMS tracks these year-over-year changes in its Landscape Source Files for the current and coming plan year.

If you are currently enrolled in an Aetna plan that is not returning for 2027, you should receive an Annual Notice of Change (ANOC) or a non-renewal notice from Aetna explaining your options. You will then have a window to pick a new plan — either another Aetna plan still offered in your county, a plan from one of the 13 other carriers in Oregon, or Original Medicare with or without a stand-alone Part D drug plan.

The two renamed Aetna Medicare Elite (HMO) plans are the same plans listed in 2026 under the HMO-POS label; the plan type did not change, only the display name.

How do I check whether an Aetna plan is offered in my Oregon county and covers my doctors and prescriptions?

To confirm whether a specific Aetna plan is offered in your Oregon county for 2027, use the Medicare Plan Finder at medicare.gov and enter your ZIP code, or call 1-800-MEDICARE (TTY 1-877-486-2048), which is available 24 hours a day, 7 days a week. The CMS Landscape counts tell you what exists statewide; the Plan Finder tells you what is available at your address.

For doctors, hospitals, and specialists, check the plan's provider directory directly with Aetna, and call your providers' offices to confirm they will accept the specific plan for 2027 — networks can change from year to year. For prescriptions, review the plan's formulary (drug list) and look up each of your medications; the Plan Finder lets you enter your drugs to see how they are covered under each plan. Your most authoritative document is the plan's Evidence of Coverage (EOC), which Aetna will send or make available before the plan year begins.

What should Oregonians do before December 7, 2026?

The Annual Enrollment Period for 2027 Medicare coverage runs from October 15, 2026 through December 7, 2026, and any choice made during that window takes effect January 1, 2027. There is no benefit to waiting until the last day, and no penalty for comparing early.

A simple checklist for Annual Enrollment 2027:

• Read the Annual Notice of Change from your current plan, if you have one, and note anything flagged as not returning.
• Make a current list of your doctors, pharmacies, and prescriptions.
• Use the Plan Finder at medicare.gov to compare the plans available in your county — from Aetna and from the other 13 Medicare Advantage carriers in Oregon.
• If you want help, call 1-800-MEDICARE.

A separate Medicare Advantage Open Enrollment Period runs January 1 through March 31, 2027, allowing one change for people already in a Medicare Advantage plan.

Where can Oregonians get free help comparing Medicare plans for 2027?

The two free, official sources are Medicare.gov and 1-800-MEDICARE (TTY 1-877-486-2048). Medicare.gov hosts the Plan Finder, which shows every Medicare Advantage and Part D plan available at your address, and 1-800-MEDICARE can walk you through enrollment and answer coverage questions at any hour.

For plan-specific details — exact premiums, deductibles, copays, covered benefits, provider networks, drug tiers, and star ratings — go directly to Aetna's materials for each plan or to the Plan Finder. This article intentionally does not list those numbers, because they vary by plan and county and are best read from the source.
