What is Aetna offering across Massachusetts for 2027?
Aetna is offering 9 Medicare Advantage plans in Massachusetts for 2027, per the CMS Landscape file. The mix is 2 HMO-POS plans and 7 PPO plans, and 8 of the 9 include Part D prescription drug coverage.

For broader context, 11 other carriers are offering Medicare Advantage plans in Massachusetts for 2027, and all carriers combined account for 97 plans statewide. The table on this page shows the full Aetna lineup; the names of the plans appear below where they are relevant to a specific point.
Which Aetna plans reach the most Massachusetts counties in 2027?
The widest county reach among Aetna's 2027 Massachusetts plans belongs to Aetna Medicare Eagle Giveback (PPO), a PPO without drug coverage, offered in 7 counties.
After that, Aetna Medicare Signature (HMO-POS) is offered in 6 counties in one of its listings. Several plans — including Aetna Medicare Elite (PPO), Aetna Medicare Enhanced (PPO) and Aetna Medicare Signature Extra (PPO) — appear in 5 counties in their broader listings, with narrower 2-county listings alongside them. A second Aetna Medicare Signature (HMO-POS) listing is offered in 2 counties. Because the same plan name can appear under more than one service-area listing, the county footprint for a given name may vary; the table on this page shows each listing separately.
What is new or not returning from Aetna in Massachusetts for 2027?
Aetna has 2 plans new for 2027 in Massachusetts and 0 plans that are not returning, based on the CMS year-over-year comparison between the CY2026 and CY2027 Landscape files.
Both new entries carry the name Aetna Medicare Enhanced (PPO) — one offered in 5 counties and one in 2 counties. In addition, Aetna Medicare Elite (PPO) is listed as renamed from Aetna Medicare Signature (PPO); if you were enrolled in a Signature PPO for 2026, the new name on your paperwork does not necessarily mean a new plan, but it is worth confirming the plan ID on your Annual Notice of Change.
How do I check whether an Aetna plan is offered in my Massachusetts county and covers my doctors and drugs?
To check whether a specific Aetna plan is offered in your Massachusetts county for 2027 and whether it covers your doctors and prescriptions, use the Medicare Plan Finder at medicare.gov, call 1-800-MEDICARE (available 24 hours a day, 7 days a week), or read the plan's own Evidence of Coverage and provider and pharmacy directories.
Medicare Advantage plans are offered county by county, so a plan listed in the statewide Aetna slate — Barnstable, Berkshire, Bristol, Essex, Middlesex, Norfolk, Plymouth, Suffolk, Worcester or any other Massachusetts county — may not be available where you live. The Plan Finder lets you enter your ZIP code, add your prescriptions and search for your providers in the plan's network. The plan's directories are the authoritative source for whether a particular doctor, hospital or pharmacy participates.
What should Massachusetts residents do before December 7, 2026?
Before December 7, 2026, Massachusetts residents who want to join, switch or drop a Medicare Advantage plan for 2027 should make that election during the Annual Enrollment Period, which runs October 15 – December 7, 2026. A choice made in that window takes effect January 1, 2027.
A reasonable checklist:
- Read the Annual Notice of Change your current plan mailed you, if you have one, and note any renaming (for example, Aetna Medicare Signature (PPO) listed as Aetna Medicare Elite (PPO) for 2027).
- List your prescriptions, dosages and pharmacies, and your regular providers.
- Use the Medicare Plan Finder at medicare.gov to compare plans available in your county for 2027.
- Confirm anything important directly with the plan before enrolling.
The date is simply the date; there is no need to rush through the comparison.
Where can Massachusetts residents get free help with Medicare questions?
Massachusetts residents can get free, official help with Medicare questions from Medicare.gov and from 1-800-MEDICARE, which is available 24 hours a day, 7 days a week.
Medicare.gov hosts the Plan Finder, the official plan details for every Medicare Advantage and Part D plan, and plain-language guides to enrollment periods and rights. 1-800-MEDICARE can walk you through enrollment windows, confirm what you are enrolled in now and connect you with the right resources. For plan-specific questions — a particular drug on the formulary, a particular specialist in network, a particular copay — the plan's own Evidence of Coverage and member services line are the authoritative source.
