Compare 102 Mississippi Medicare Advantage Plans for 2027 From 9 Carriers

JACKSON, Miss. — For the 2027 plan year, Mississippi residents on Medicare will have 102 Medicare Advantage plans to compare, offered by nine carriers, according to the Centers for Medicare & Medicaid Services (CMS) Landscape Source Files. The Annual Enrollment Period runs from October 15 through December 7, 2026, and a choice made during that window takes effect on January 1, 2027.

Those 102 plans are counted once statewide. Because Medicare Advantage is sold county by county, the plans available in your county will be a subset of the statewide list. The point of this guide is to help you narrow the statewide picture down to what is actually offered where you live, using the official tools before December 7.

How many Medicare Advantage plans are offered in Mississippi for 2027?

Mississippi has 102 Medicare Advantage plans for 2027 from 9 carriers, per the CMS MA Landscape Source File. Of those statewide plans, 96 include Part D prescription drug coverage. There are 19 plans new for 2027 and 10 plans that are not returning from 2026.

Because each plan is sold county by county, the number of plans you can actually enroll in will be smaller than 102. A plan listed statewide may not be offered in your county, and two neighbors in different counties can see different menus. The statewide count is a starting point; the Medicare Plan Finder narrows it to your ZIP code.

What types of Medicare Advantage plans are available in Mississippi for 2027, including Special Needs Plans?

Across Mississippi for 2027, the 102 plans break down by type into 30 HMO plans, 20 HMO-POS plans and 52 PPO plans. Special Needs Plans (SNPs) total 51 statewide: 36 Dual-Eligible SNPs (D-SNP), 12 Chronic Condition SNPs (C-SNP) and 3 Institutional SNPs (I-SNP).

Each type has its own rules about networks and referrals. HMOs usually ask you to use in-network providers; HMO-POS plans allow some out-of-network use; PPOs typically give you broader out-of-network access at a different cost share. SNPs are limited to people who meet specific eligibility rules — for example, D-SNPs are for people who have both Medicare and Medicaid. The plan's own documents, not this article, spell out those rules in detail.

Which carriers offer Mississippi Medicare Advantage plans for 2027?

Nine carriers offer Medicare Advantage plans in Mississippi for 2027. In alphabetical order, with statewide plan counts from the CMS Landscape file: Aetna (CVS Health) with 13 plans, American Health Advantage of MS with 1 plan, Centene (WellCare) with 13 plans, Devoted Health with 10 plans, HealthSpring with 12 plans, Healthy Mississippi, Inc. with 4 plans, Humana with 25 plans, UnitedHealthcare with 18 plans, and Zing Health with 6 plans.

The full carrier and plan tables are rendered elsewhere on this page. Carrier footprints differ by county: a carrier that lists 25 plans statewide may offer only a handful of them in any one county, and some carriers concentrate in specific regions. Confirm your county's list in the Medicare Plan Finder.

How do I compare Medicare Advantage plans in my own Mississippi county for 2027?

Compare plans in your own Mississippi county for 2027 by entering your ZIP code into the Medicare Plan Finder at medicare.gov, which returns only the plans offered where you live. Then work through the plan details one at a time.

A step-by-step order that works well:

1. Doctors. Check whether your primary care provider and specialists are in each plan's network. Call the office to confirm, and ask about the specific plan name and contract/plan ID. 2. Hospitals. Confirm your preferred hospital system participates with the plan. 3. Prescriptions. Enter every medication, dosage and frequency into Plan Finder so it can show how each plan's formulary treats your drugs. 4. Pharmacies. Pick a pharmacy you can actually use. Cost sharing can vary between preferred, standard and mail-order pharmacies within the same plan. 5. Annual Notice of Change (ANOC). If you are already in a Medicare Advantage or Part D plan, read the ANOC your plan mailed in September. It explains what is changing for 2027, including whether the plan is being discontinued. 6. Evidence of Coverage (EOC). For any plan you are seriously considering, review the EOC for the full rules.

If a plan is one of the 10 not returning for 2027, you will get a non-renewal notice from the carrier and will have options during the Annual Enrollment Period and a Special Enrollment Period into early 2027.

What should Mississippi residents do before December 7, 2026?

Before December 7, 2026, Mississippi residents should confirm the plan they want for 2027 and complete any enrollment through medicare.gov, 1-800-MEDICARE or the plan directly. December 7, 2026 is the last day of the Annual Enrollment Period for coverage that starts January 1, 2027.

A simple checklist:

• Read your current plan's ANOC side by side with the plan's 2027 details.
• Make a written list of your doctors, hospitals, medications and preferred pharmacy.
• Run that list through the Medicare Plan Finder for your ZIP code.
• Save or print confirmation of any enrollment.

Outside of Annual Enrollment, there is also a Medicare Advantage Open Enrollment Period from January 1 through March 31, 2027, with its own rules for one-time changes.
