Medicare in Missouri: 2025 Guide
Missouri has approximately 1.4 million Medicare beneficiaries, with Medicare Advantage plans enrolling about 50% of the market. Kansas City and St. Louis are Missouri's most competitive Medicare Advantage markets, while rural Missouri has considerably more limited plan availability. Missouri expanded Medicaid in 2021 through voter-approved Amendment 2 (MO HealthNet), and the state's free Medicare counseling program goes by the distinctive name CLAIM — Community Leaders Assisting the Insured of Missouri.
Medicare Advantage Plans in Missouri
Missouri's two major metro areas anchor its Medicare Advantage market. Kansas City — including both the Missouri and Kansas sides of the metro — typically offers 30 or more plans, with carriers including UnitedHealth, Humana, Centene/WellCare, and Anthem competing actively for enrollees. St. Louis similarly offers a competitive market with 30 or more plans, and the bi-state metro can include plans from both Missouri and Illinois carriers. Both cities feature plans with $0 or low premiums and strong supplemental benefits such as dental, vision, hearing, and fitness programs, often with access to major regional health systems including BJC HealthCare, SSM Health, and Saint Luke's Health System.
Beyond the major metros, plan availability decreases substantially. Springfield and Columbia offer moderate plan counts, but much of rural Missouri — particularly in the Ozarks, the Bootheel, and the northwestern and northeastern corners of the state — has a limited selection of Medicare Advantage plans. Provider network adequacy can also be a concern in rural areas, particularly for specialty care. Missourians in rural counties with limited plan options should weigh whether Original Medicare with a Medigap supplement better serves their needs, especially if they frequently travel or need access to providers in Kansas City, St. Louis, or out of state. CLAIM counselors are available statewide to help assess options at no cost.
Missouri expanded Medicaid under the ACA through Amendment 2, passed by voters in August 2020 and implemented in 2021 under the MO HealthNet program. This has expanded dual-eligible populations and D-SNP availability for low-income Missourians who qualify for both Medicare and Medicaid.
Medicare Savings Programs in Missouri
Missouri's Medicare Savings Programs are administered through MO HealthNet, the state's Medicaid program, overseen by the Missouri Department of Social Services (DSS) and the Department of Health and Senior Services (DHSS). The QMB, SLMB, QI, and QDWI programs help low-income Medicare beneficiaries pay Part A and/or Part B premiums, deductibles, and cost-sharing. Missouri's Medicaid expansion under Amendment 2 has extended full dual-eligible coverage to a broader group of low-income adults, including some Medicare beneficiaries who may now qualify for MO HealthNet alongside Medicare — providing the most comprehensive cost protection available.
To apply for Medicare Savings Programs in Missouri, contact your local Family Support Division (FSD) office or the MO HealthNet Division. MSP enrollment automatically triggers Extra Help for Part D drug costs. CLAIM counselors can guide applicants through the process and help identify all available state and federal savings programs. Given Missouri's significant rural poverty pockets, these programs are especially important for many fixed-income Missourians.
State Pharmaceutical Assistance in Missouri
Missouri does not operate a State Pharmaceutical Assistance Program (SPAP) to supplement Medicare Part D drug coverage. Missourians who need help with prescription drug costs should apply for the federal Extra Help (Low Income Subsidy) program through the Social Security Administration. Qualifying for a Medicare Savings Program automatically grants Extra Help eligibility. CLAIM counselors can also help identify pharmaceutical manufacturer patient assistance programs for specific high-cost drugs and assist with Extra Help applications at no cost.
Getting Free Medicare Help in Missouri
CLAIM — Community Leaders Assisting the Insured of Missouri — is Missouri's free Medicare counseling program, one of the few state SHIP programs with a distinctive community-focused name that reflects its grassroots, volunteer-driven model. CLAIM is administered through the Missouri Department of Health and Senior Services (DHSS) and funded by the federal government. Trained volunteer counselors across Missouri help beneficiaries compare Medicare Advantage, Medigap, and Part D plans; apply for Medicare Savings Programs and Extra Help; understand dual-eligible benefits; and resolve billing disputes. CLAIM counselors are not affiliated with any insurer and never sell products.
To reach CLAIM, call 1-800-390-3330. Local CLAIM counseling sites are available throughout Missouri, including in rural communities. CLAIM is particularly active during the Annual Enrollment Period (October 15 – December 7) and conducts year-round outreach through community events, senior centers, and libraries across the state.
Kansas City and St. Louis metro areas each typically offer 30 or more Medicare Advantage plans from multiple carriers. Springfield and Columbia generally have 15–25 plans. Rural Missouri counties — especially in the Ozarks, the Bootheel, and the far corners of the state — may have only 5–15 plans available. Use Medicare.gov's Plan Finder or call CLAIM at 1-800-390-3330 to check exact availability in your county.
Missouri voters approved Medicaid expansion through Amendment 2 in 2020, and coverage took effect in 2021 under MO HealthNet. The expansion primarily covers adults aged 19–64 without Medicare, but it has increased the number of Missourians who qualify for full dual Medicare-Medicaid enrollment once they age into Medicare at 65. Dual-eligible beneficiaries receive comprehensive cost protection and may qualify for D-SNPs that coordinate both programs. If you have both Medicare and a low income, contact CLAIM at 1-800-390-3330 or a local FSD office to check whether you qualify for MO HealthNet alongside Medicare.
CLAIM (Community Leaders Assisting the Insured of Missouri) provides free, unbiased Medicare counseling to all Missouri residents. Trained volunteer counselors can help you compare plans, apply for savings programs, understand your MO HealthNet dual-eligible options, and resolve billing issues. Call 1-800-390-3330 to speak with a counselor or find a local CLAIM site. All services are free and counselors do not sell insurance.
