Because Medicare Advantage plans are approved county by county, a plan listed statewide may or may not be available where you live in Maine. The counts below describe what Aetna is offering across the state; your own choices depend on your ZIP code.
How many Aetna Medicare Advantage plans are offered in Maine for 2027?
Aetna is offering 6 Medicare Advantage plans in Maine for 2027, per the CMS Landscape Source File. By plan type, that breaks down to 5 HMO-POS plans and 1 PPO plan. Two of the six are Dual Eligible Special Needs Plans (D-SNPs); Aetna is not offering a Chronic Condition SNP (C-SNP) or Institutional SNP (I-SNP) in Maine for 2027. Five plans include Part D prescription drug coverage, and one is offered without drug coverage.
For context, five other carriers are also offering Medicare Advantage plans in Maine for 2027, and all carriers together account for 50 plans statewide. Aetna is one piece of that broader market, and the right fit for any individual depends on county availability, provider networks and drug lists — details this article does not evaluate.
Which Aetna Medicare Advantage plans reach the most Maine counties in 2027?
The widest county reach among Aetna's 2027 Maine plans belongs to Aetna Medicare Full Dual (HMO-POS D-SNP), offered in 16 counties, followed by Aetna Medicare Partial Dual (HMO-POS D-SNP) in 9 counties and Aetna Medicare Eagle Giveback (PPO) in 8 counties. The remaining Aetna plans are Aetna Medicare Signature (HMO-POS), offered in 5 counties in one version and 3 counties in another, and Aetna Medicare Enhanced (HMO-POS), offered in 3 counties.
The complete county-by-county picture is laid out in the tables rendered from the CMS data on this page. "Widest reach" simply means the plan appears on the Landscape file in the most Maine counties for 2027 — it is not a judgment about quality, price or benefits.
What is new or not returning from Aetna in Maine for 2027?
Aetna has no new Medicare Advantage plans launching in Maine for 2027, and one of its Maine plans from 2026 is not returning for 2027, based on the year-over-year comparison in the CMS Landscape files. If you are currently enrolled in an Aetna plan in Maine, you should receive an Annual Notice of Change (ANOC) from Aetna by late September 2026 explaining what is changing for your specific plan, including whether it will still be offered in your county.
If a plan you are in does not continue into 2027, you will have options during the Annual Enrollment Period and, in some cases, a Special Enrollment Period. The notice from the plan will spell out what applies to you.
How do I check whether an Aetna plan is offered in my Maine county and covers my doctors and drugs?
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. Entering your ZIP code shows which Aetna Medicare Advantage plans are available in your Maine county for 2027, along with every other plan in your area.
From there, you can confirm three things that matter most: whether your doctors and hospitals are in the plan's network, whether your prescriptions are on the plan's formulary, and whether any pharmacies you use are preferred. For the most authoritative detail on a specific plan, review the plan's Evidence of Coverage and provider and pharmacy directories, which Aetna publishes directly. This site does not list premiums, copays, benefits, star ratings or network details for any plan.
What should I do before December 7, 2026?
Before December 7, 2026, review your current coverage and compare it to what will be available for 2027 in your Maine county. The Annual Enrollment Period for Medicare Open Enrollment 2027 runs October 15 through December 7, 2026, and whatever you choose during that window takes effect January 1, 2027.
A simple checklist helps:
- Read the Annual Notice of Change from your current plan when it arrives.
- Make a list of your doctors, hospitals and prescriptions.
- Use medicare.gov's Plan Finder to compare every plan available in your county, including but not limited to Aetna's.
- If you qualify for both Medicare and Medicaid (MaineCare), look specifically at D-SNP options, which include two Aetna plans statewide.
There is no need to rush — the date is fixed, and you have the full window to decide.
Where can I get free help comparing Medicare plans in Maine for 2027?
The two free, official sources are medicare.gov and 1-800-MEDICARE (TTY 1-877-486-2048). Both can walk you through plans available in your Maine county for 2027, including Aetna's six plans and plans from the other five carriers in the state.
If you prefer to work from paper, you can request the "Medicare & You" handbook through medicare.gov or by phone. For plan-specific questions — a particular drug tier, a specific specialist, a prior authorization rule — contact Aetna directly using the phone number on the plan's materials.
