Aetna's Medicare Advantage plans in Portland for 2027: what changed, what to check

PORTLAND, Ore. — Fall 2026. If you have an Aetna Medicare Advantage plan in Portland, or you are weighing one for next year, the 2027 lineup looks different from 2026. According to the CMS Medicare Advantage Landscape Source File for the coming plan year, Aetna will offer 2 Medicare Advantage plans in Multnomah County in 2027: one new plan and one that has been renamed. Two plans the carrier offered in 2026 are not returning. You have until December 7, 2026 to compare and switch for coverage that begins January 1, 2027.

MyMedicarePlans.org is an independent consumer site and is not affiliated with Aetna or any other insurer. Aetna is one of 10 carriers offering Medicare Advantage plans in the county for 2027; across all carriers, Multnomah County will have 45 Medicare Advantage plans available.

What Aetna Medicare Advantage plans are available in Portland for 2027?

Aetna will offer 2 Medicare Advantage plans in Multnomah County — the county Portland sits in — for the 2027 plan year, per the CMS Landscape Source File. By type, that is 1 HMO and 1 HMO-POS. One of the two includes Part D prescription drug coverage. Aetna is not offering any Special Needs Plans (D-SNP, C-SNP or I-SNP) in the county next year.

The plans, in alphabetical order, are:

• Aetna Medicare Eagle (HMO) — HMO, without drug coverage — new for 2027
• Aetna Medicare Elite (HMO) — HMO-POS, with drug coverage — renamed (was Aetna Medicare Elite (HMO-POS) in 2026)

The table below lists every plan with the carrier and plan type as CMS files them.

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

Compared with 2026, Aetna has 1 new plan, 1 renamed plan, and 2 plans that are not returning. The new plan for 2027 is Aetna Medicare Eagle (HMO). Aetna Medicare Elite kept its name on the marquee but changed plan type — CMS lists it as HMO-POS for 2027, where it was HMO-POS under a slightly different label the year before. The specific premiums, networks, drug lists and benefit details for each 2027 plan are in the plan's own Evidence of Coverage and Summary of Benefits, which you can view through Medicare.gov.

If one of the Aetna plans you were enrolled in for 2026 is not on the 2027 list, you should receive a non-renewal notice from the plan explaining your options. You can switch to another Medicare Advantage plan during the Annual Enrollment Period, or you may qualify for a Special Enrollment Period if your plan leaves the market.

What happens if I do nothing before December 7, 2026?

Nothing happens automatically to a person who does nothing — as long as the plan is still being offered in 2027. A returning plan simply renews on January 1, 2027, with any changes spelled out in the plan's Annual Notice of Change (ANOC), which plans mail each September. If your plan is not returning, you will need to either pick a different plan during the Annual Enrollment Period or you will revert to Original Medicare (Parts A and B) and can add a stand-alone Part D plan.

The Annual Enrollment Period runs October 15 through December 7, 2026. If you want more time after that, the Medicare Advantage Open Enrollment Period (January 1 – March 31, 2027) lets people already in a Medicare Advantage plan make one change.

How do I check an Aetna plan against my doctors and prescriptions?

Before you pick any plan, line it up against three personal lists: your doctors and hospitals, your regular prescriptions, and the pharmacies you actually use. There are three reliable ways to do this:

1. Medicare.gov Plan Finder. Enter your ZIP code, add your drugs and preferred pharmacies, and the tool will show each plan's drug coverage and estimated yearly costs for you specifically. 2. Call 1-800-MEDICARE (TTY 1-877-486-2048), 24 hours a day, 7 days a week, for help comparing plans. 3. Ask the plan directly. The plan's provider directory and formulary (drug list) are the authoritative sources for whether your doctor is in-network and whether your medication is covered, and at what tier.

Networks and formularies can change from year to year, so a plan that fit in 2026 may fit differently in 2027. Always confirm with the plan before enrolling.

What Medicare rules and figures should I know for 2027?

CMS has already published some program-wide 2027 figures. The Part D out-of-pocket cap rises to $2,400 in 2027 (up from $2,100 in 2026). The Part D maximum deductible is $700 in 2027 (up from $615 in 2026). The Part D national base beneficiary premium for 2027 is $41.33 — that is a formula input CMS uses, not what any one plan will charge you.

Some pieces are not out yet: the 2027 standard Part B premium and deductible, and the 2027 IRMAA income brackets, are typically announced by CMS in the fall, usually in November. Do not rely on projections; wait for the official numbers.

Two other features still apply in 2027: the coverage gap (the old "donut hole") remains gone — Part D now has three phases — and the Medicare Prescription Payment Plan lets you spread your out-of-pocket drug costs across the calendar year in monthly amounts instead of paying at the pharmacy counter.
