- If your plan is on the non-returning list, your carrier must mail you an Annual Notice of Change or non-renewal letter, generally arriving in the fall.

How many Medicare Advantage plans are leaving Missouri for 2027, and which carriers are affected?
Twenty-one Medicare Advantage plans available in Missouri in 2026 are not in the CMS 2027 file for any Missouri county. The affected carriers are Aetna (CVS Health), Centene (WellCare), Elevance Health (Anthem), HealthSpring, Provider Partners Health Plans, and UnitedHealthcare. The full list, with contract type and the number of counties each plan served in 2026, appears in the table on this page.
Statewide, 174 Medicare Advantage plans from 12 carriers will still be offered somewhere in Missouri in 2027. A plan is sold county by county, so a plan on the non-returning list may never have been available where you live, and a plan returning for 2027 may or may not be sold in your county.
Which non-returning Missouri plans served the most counties in 2026?
The largest statewide footprints among the 21 non-returning plans belong to several UnitedHealthcare contracts. UHC Complete Care AM-1, UHC Complete Care Support AM-1A, UHC Dual Complete MO-S3, UHC Dual Complete MO-V001, and UHC Medicare Advantage AM-0002 were each offered in 115 Missouri counties in 2026. Two Provider Partners Health Plans institutional special needs plans — Provider Partners Missouri Community Plan and Provider Partners Missouri Essential Plan — were each offered in 65 counties. Smaller statewide footprints among the discontinued plans include three AARP Medicare Advantage from UHC plans (27, 27, and 15 counties), several Aetna Medicare plans (ranging from 9 to 21 counties), Healthy Blue Dual (10 counties), four HealthSpring plans (7 to 13 counties), and Wellcare Giveback (9 counties).
Those county counts describe where each plan was sold in 2026, not everywhere in Missouri.
How can a Missouri member tell if their Medicare Advantage plan is being discontinued for 2027?
There are two reliable signals. First, the carrier is required to mail a non-renewal notice, usually arriving in the fall of 2026, telling you the plan will not be offered in 2027. Second, you can match the exact plan name on your member ID card against the list of 21 plans in the table above — the names here are spelled exactly as CMS lists them.
If you cannot find the letter, call the member services number on the back of your card, or call 1-800-MEDICARE (1-800-633-4227), TTY 1-877-486-2048, 24 hours a day, seven days a week.
What happens to a Missouri enrollee who does nothing before January 1, 2027?
If your plan is on the non-returning list and you make no choice, you will be returned to Original Medicare (Part A and Part B) on January 1, 2027. You will not have Medicare Part D prescription drug coverage unless you actively enroll in a stand-alone Part D plan or in a Medicare Advantage plan that includes drug coverage. You will also not have the extra benefits a Medicare Advantage plan may have included.
Original Medicare will pay for covered hospital and medical services under the standard federal rules, but you will be responsible for the deductibles and coinsurance Original Medicare sets.
What Special Enrollment Period and Medigap rights apply when a Medicare Advantage plan leaves Missouri?
Members of a non-renewed Medicare Advantage plan qualify for a Special Enrollment Period that runs through the end of February 2027. During that window you can join a different Medicare Advantage plan or a stand-alone Part D plan, with coverage generally starting the first of the month after you enroll.
Federal rules also give people in this situation a guaranteed-issue right to buy certain Medigap (Medicare Supplement) policies without medical underwriting for a limited time after the Medicare Advantage coverage ends. Missouri may apply additional state protections; the Missouri Department of Commerce and Insurance can explain which Medigap plans and timeframes apply in Missouri.
How can a Missourian check which Medicare Advantage plans are offered in their county for 2027?
Use the Medicare Plan Finder at medicare.gov and enter your ZIP code, or call 1-800-MEDICARE. The Plan Finder shows every 2027 Medicare Advantage plan and stand-alone Part D plan available in your county, along with premiums, deductibles, drug lists, provider networks, and star ratings specific to each plan.
Because availability is set at the county level, the 174 plans counted statewide are not all offered everywhere; your county may show more or fewer options.
What should Missouri members do before December 7, 2026?
Before December 7, 2026, read the Annual Notice of Change or non-renewal letter from your current plan, write down the prescriptions you take and the doctors and hospitals you want to keep, and compare the 2027 plans available in your county on medicare.gov. Enroll in the plan you choose by December 7, 2026, for coverage that starts January 1, 2027.
If your plan is one of the 21 not returning, remember that your Special Enrollment Period runs into February 2027, so you still have a path if you need more time.
Where can Missourians get free, unbiased help choosing a 2027 plan?
Free help is available from Medicare itself. Call 1-800-MEDICARE (1-800-633-4227), TTY 1-877-486-2048, 24 hours a day, seven days a week, or use the Plan Finder and chat tools at medicare.gov. Both will walk through the 2027 options in your county without steering you to a particular carrier.
