Anthem Medicare Advantage in Missouri for 2027: 6 Plans, County by County

JEFFERSON CITY — Anthem Medicare Advantage will offer six plans across Missouri for the 2027 plan year, according to the CMS Medicare Advantage Landscape Source Files for CY2026 and CY2027. The lineup includes a mix of HMO, HMO-POS and PPO options, plus Special Needs Plans aimed at specific groups of enrollees. This article is published by an independent Medicare education site; it is not the government and not Anthem.

Because Medicare Advantage plans are approved county by county, a plan listed statewide may or may not be available where you live. The counts below describe what Anthem files with CMS for Missouri as a whole for 2027.

What does Anthem offer across Missouri for 2027?

Anthem files 6 Medicare Advantage plans in Missouri for 2027: 2 HMOs, 3 HMO-POS plans and 1 PPO. Of those, 5 include Part D prescription drug coverage and 1 does not.

Three of the six are Special Needs Plans: 2 Dual Eligible SNPs (for people who have both Medicare and Medicaid) and 1 Chronic Condition SNP (for people with a qualifying chronic condition). There are no Institutional SNPs in Anthem's 2027 Missouri lineup. CMS groups Anthem under "Elevance Health (Anthem)" in its filings.

For context, 11 other carriers also offer Medicare Advantage plans somewhere in Missouri for 2027, and all carriers together file 174 plans statewide. The full carrier and plan tables appear elsewhere on this page.

Which Anthem plans reach the most Missouri counties in 2027?

Two Anthem Dual Eligible SNPs tie for the widest county reach in Missouri for 2027: Anthem Full Dual Advantage (HMO D-SNP) and Anthem Full Dual Advantage 2 (HMO D-SNP) are each offered in 85 counties. Both include drug coverage, and both are limited to people who qualify based on dual Medicare and Medicaid eligibility.

After those two, Anthem Veteran (PPO) is offered in 18 counties and does not include drug coverage. The two Anthem Medicare Advantage (HMO-POS) plans are offered in 10 counties and 8 counties respectively, both with drug coverage. Anthem Chronic Care (HMO-POS C-SNP) is offered in 3 counties and also includes drug coverage; eligibility is limited to people with a qualifying chronic condition.

The point of the county counts is simple: a plan in the statewide list may not be approved in your county, so the service area is the first thing to check.

What is new or not returning from Anthem in Missouri for 2027?

Anthem has 0 new Medicare Advantage plans in Missouri for 2027, and 1 plan it offered in 2026 is not returning for 2027. That year-over-year comparison comes from the CMS Landscape Source Files for CY2026 and CY2027.

If you are currently enrolled in an Anthem plan, watch for the Annual Notice of Change (ANOC) that your plan mails each fall. The ANOC is the document that tells you whether your specific plan is continuing, changing or ending, and what that means for you on January 1, 2027. If a plan is non-renewing, CMS and the carrier send written notice with instructions on your options and timing.

How do I check whether an Anthem plan is offered in my Missouri county and covers my doctors and prescriptions?

Use the Medicare Plan Finder at medicare.gov, where you enter your ZIP code and county and see the plans actually available to you for 2027. The statewide list on this page tells you what Anthem files in Missouri; the Plan Finder tells you what is approved in your county.

Once you see the plans available in your county, check three things for each plan you are considering:

• Doctors and hospitals: look up each provider in that plan's online directory, or call the plan to confirm current network status.
• Prescriptions: enter your drug list into the Plan Finder, or review the plan's formulary directly, to see how each drug is covered.
• Plan documents: the Summary of Benefits and the Evidence of Coverage explain how a plan works in detail.

If you prefer to work by phone, 1-800-MEDICARE (TTY 1-877-486-2048) is available 24 hours a day, seven days a week.

What should Missouri Medicare beneficiaries do before December 7, 2026?

The Annual Enrollment Period runs October 15 through December 7, 2026, and any choice made in that window takes effect January 1, 2027. There is no advantage to deciding on a specific day inside the window; what matters is that your decision is on file by December 7.

A simple checklist for the weeks before December 7:

• Read your current plan's Annual Notice of Change for 2027.
• Make a current list of your doctors, pharmacies and prescriptions.
• Compare the plans available in your county on medicare.gov.
• Confirm anything important directly with the plan before you enroll.

People who qualify for a Special Needs Plan — for example, through Medicaid eligibility or a qualifying chronic condition — may also have Special Enrollment Periods outside the fall window. The Plan Finder and 1-800-MEDICARE can confirm which periods apply to you.
