Does Aetna change its Milwaukee MA plans for 2027?

MILWAUKEE — As the 2027 Annual Enrollment Period runs from October 15 to December 7, 2026, Aetna is one of several insurers selling Medicare Advantage plans to people on Medicare in Milwaukee County. For 2027, Aetna is offering six Medicare Advantage plans in the county, according to the CMS Medicare Advantage Landscape Source File — the same number it offered for 2026, with no plans added and none pulled.

That stability does not mean the plans themselves are unchanged. Every Medicare Advantage plan sends members an Annual Notice of Change (ANOC) each fall that spells out what will be different on January 1. This article walks through Aetna's 2027 Milwaukee County lineup at a high level and shows you how to check your own doctors and prescriptions against each plan before the December 7 deadline.

How many Medicare Advantage plans does Aetna offer in Milwaukee County for 2027?

Aetna is offering six Medicare Advantage plans in Milwaukee County for 2027. By plan type, that is one HMO-POS plan and five PPO plans. Five of the six include Medicare Part D prescription drug coverage; one does not.

Aetna is not offering any Special Needs Plans (SNPs) in Milwaukee County for 2027 — no Dual-Eligible SNP, no Chronic Condition SNP and no Institutional SNP. If you qualify for an SNP because of Medicaid eligibility or a specific chronic condition, you would need to look at other carriers in the county.

The full plan-by-plan list appears in the table below.

What are Aetna's 2027 Medicare Advantage plans in Milwaukee?

Here are all six Aetna plans available to Milwaukee County residents for 2027, listed alphabetically and exactly as CMS lists them:

• Aetna Medicare Eagle (PPO) — PPO, without drug coverage
• Aetna Medicare Enhanced (PPO) — PPO, with drug coverage
• Aetna Medicare Signature (HMO-POS) — HMO-POS, with drug coverage
• Aetna Medicare Signature (PPO) — PPO, with drug coverage
• Aetna Medicare Signature Extra (PPO) — PPO, with drug coverage
• Aetna Medicare Value Care (PPO) — PPO, with drug coverage

We are not listing premiums, deductibles, copays, extra benefits, provider networks or star ratings for any of these plans. Those details change each year and are specific to each plan; the official source is the plan's 2027 Evidence of Coverage, Summary of Benefits and provider and pharmacy directories, or the Medicare Plan Finder at medicare.gov.

What is new or not returning in Aetna's Milwaukee lineup for 2027?

For 2027, Aetna is not adding any new Medicare Advantage plans in Milwaukee County, is not discontinuing any of its current plans, and has not renamed any. The carrier is renewing all six plans it offered for 2026.

That is different from a non-renewal situation. If a plan were leaving, members would get a formal CMS notice and a Special Enrollment Period. Because Aetna's Milwaukee plans are all returning, members will instead receive an Annual Notice of Change by late September listing exactly what is different for January 1, 2027 — things like the premium, the drug deductible, the copays for a doctor visit or a hospital stay, the pharmacy network, the drug formulary and any extra benefits. Read it before you decide to stay or switch.

How do I check an Aetna plan against my doctors and prescriptions before December 7?

The fastest way is the Medicare Plan Finder at medicare.gov. You can enter your ZIP code, add your prescriptions and preferred pharmacy, and see each plan's cost and coverage estimate side by side. You can also call 1-800-MEDICARE, 24 hours a day, seven days a week.

A simple checklist for any Aetna plan on the list above — or any other carrier's plan:

1. Confirm your doctors and hospitals are in the plan's 2027 network. Check with the plan directly, not just the directory, because directories can lag. 2. Check that each of your prescriptions is on the 2027 formulary, at what tier, and whether it requires prior authorization or step therapy. 3. Confirm your regular pharmacy is a preferred in-network pharmacy for that plan. 4. If you travel or spend part of the year outside Wisconsin, ask how the plan covers out-of-area care — this is where the HMO-POS vs. PPO distinction matters. 5. Compare the total expected yearly cost (premium plus expected copays and drug costs), not just the monthly premium.

Six other carriers also offer Medicare Advantage plans in Milwaukee County for 2027. Across all carriers, there are 52 Medicare Advantage plans in the county, so Aetna's six are one slice of a broader market worth comparing.

What Medicare dates and dollar figures should Milwaukee residents know for 2027?

The Annual Enrollment Period runs October 15 through December 7, 2026. Any change you make in that window takes effect January 1, 2027. If you do nothing, your current plan renews with the changes described in its ANOC.

If you end up in a Medicare Advantage plan on January 1 and want to switch to a different Advantage plan or back to Original Medicare, the Medicare Advantage Open Enrollment Period runs January 1 through March 31, 2027.

For Part D in 2027, CMS has confirmed:

• The annual out-of-pocket cap on covered Part D drugs rises to $2,400 (up from $2,100 in 2026).
• The maximum Part D deductible a plan can charge rises to $700 (up from $615 in 2026).
• The national base beneficiary premium is $41.33 — a formula input CMS uses, not what any particular plan charges.

The coverage gap (the old "donut hole") has been gone since 2025; Part D now has three phases. If drug costs hit hard early in the year, ask about the Medicare Prescription Payment Plan, an optional program that spreads your out-of-pocket drug costs across monthly payments.

The 2027 standard Part B premium and deductible, and the 2027 IRMAA income brackets for higher-income surcharges, have not been announced yet. CMS normally publishes those figures in the fall, usually in November. We will update our coverage when they do.
