What is new or not returning for Aetna in Mississippi for 2027?

For plan year 2027 in Mississippi, Aetna is not introducing any new Medicare Advantage plans and is not discontinuing any — zero new, zero exiting — based on the year-over-year comparison between the CY2026 and CY2027 CMS Landscape Source Files. That means the 13 plans on the 2027 statewide list are returning plans. Even so, returning plans can change their service areas, provider networks, drug formularies, and cost-sharing from one year to the next, so current members should still read their Annual Notice of Change for 2027 to see what, if anything, has shifted for the specific plan they are on.

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

To check whether a specific Aetna plan is offered in your Mississippi county for 2027, enter your ZIP code into the Medicare Plan Finder at medicare.gov or call 1-800-MEDICARE (TTY 1-877-486-2048), available 24 hours a day, seven days a week. Because Medicare Advantage plans are sold county by county, a plan on Aetna's statewide list — for example, one offered in 70 counties or one offered in only 4 — may not be available at your address. Once you confirm a plan serves your county, use Plan Finder to check whether your doctors and preferred hospitals are in-network, whether your prescriptions are on the plan's formulary, and what the plan's cost-sharing looks like. For the fullest detail, request the plan's Evidence of Coverage and provider and pharmacy directories directly from Aetna.

What should Mississippi residents do before December 7, 2026?

Before December 7, 2026, Mississippi residents should review their current Medicare coverage against the plans available for 2027 and make any changes they want in time for a January 1, 2027 effective date. The Annual Enrollment Period for 2027 — also called Medicare Open Enrollment 2027 — runs October 15 – December 7, 2026. During that window you can join, switch, or drop a Medicare Advantage plan, or move between Original Medicare and Medicare Advantage. A good checklist: read your current plan's Annual Notice of Change, list your prescriptions and preferred providers, compare options on the Medicare Plan Finder, and confirm that the plan you want is offered in your county.
