Because Medicare Advantage plans are sold county by county, a plan listed statewide may not be available in the county where you live.

For context, 15 other carriers also offer Medicare Advantage plans somewhere in the state for 2027, and the full statewide field across all carriers is 117 plans.

Which Aetna plans reach the most Wisconsin counties in 2027?

The Aetna Wisconsin plan with the widest county reach for 2027 is Aetna Medicare Eagle (PPO), a PPO without drug coverage, offered in 32 counties. The remaining PPO and HMO-POS plans show smaller county footprints.

Several Aetna names appear more than once because CMS treats each contract/plan combination as its own listing. The 2027 statewide list includes Aetna Medicare Enhanced (PPO) in 17 counties (renamed from Aetna Medicare Premier (PPO)); another Aetna Medicare Enhanced (PPO) in 7 counties; Aetna Medicare Signature (HMO-POS) in 7 counties; two Aetna Medicare Signature (PPO) listings, one in 17 counties and one in 15 counties; Aetna Medicare Signature Extra (PPO) in 7 counties; and Aetna Medicare Value Care (PPO) in 7 counties. The full plan-by-plan breakdown is in the table on this page.

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

Aetna has 0 new Medicare Advantage plans entering Wisconsin for 2027 and 0 plans that will not return for 2027, based on the CMS Landscape files for 2026 and 2027.

There is one naming change worth noticing: the plan previously sold as Aetna Medicare Premier (PPO) is listed for 2027 as Aetna Medicare Enhanced (PPO). A rename is not the same as a new plan or a plan leaving, but it can be confusing on paperwork. If you see "Premier" on 2026 materials and "Enhanced" on 2027 materials, that is why. Your Annual Notice of Change from the plan will spell out what, if anything, is changing for you.

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

To check whether a specific Aetna plan is offered in your Wisconsin 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), available 24 hours a day, 7 days a week. A plan that shows up on a statewide list may not be sold in your county.

Once you see which plans are available at your address, confirm the details that matter to you directly with the plan. That means:

• Checking the plan's provider directory for the doctors, clinics and hospitals you use.
• Checking the plan's formulary (drug list) for each prescription you take, including dosage and pharmacy.
• Reading the plan's Summary of Benefits and Evidence of Coverage for how the plan handles costs, referrals and prior authorization.

This site does not publish premiums, deductibles, copays, benefits, networks, drug lists or star ratings for any plan. Those details live in the plan's own documents and on medicare.gov so you are always comparing current, official information.

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

Before December 7, 2026, Wisconsin beneficiaries can use the Annual Enrollment Period, which runs October 15 through December 7, 2026, to join, switch or drop a Medicare Advantage plan for 2027. Any choice made during that window takes effect January 1, 2027.

A simple, unhurried checklist: 1. Read the Annual Notice of Change from your current plan, which arrives in the fall. 2. Make a short list of your doctors, hospitals and prescriptions. 3. On medicare.gov, enter your ZIP code and compare the 2027 plans available in your county, including any Aetna plans. 4. Verify your providers and medications with each plan you are seriously considering. 5. Enroll by December 7, 2026 if you want to change for January 1, 2027.

If you are happy with your current coverage and it is still being offered in your county for 2027, you do not have to do anything.

Where can Wisconsin residents get free help comparing 2027 plans?

Wisconsin residents can get free, official help comparing 2027 Medicare Advantage plans by going to medicare.gov or calling 1-800-MEDICARE (TTY 1-877-486-2048), 24 hours a day, 7 days a week. Both are run by Medicare itself and cover every plan available at your address, not just one carrier.

For plan-specific questions — a provider, a drug, how a benefit works — the plan's own member services line and its Evidence of Coverage are the authoritative sources.
