Centene Corporation is a major U.S. healthcare enterprise focused on providing access to affordable, quality-focused healthcare through Medicaid, Medicare and Health Insurance Marketplace programs. The company has operated government-sponsored healthcare programs for approximately 40 years and currently serves millions of members across the United States. As of June 30, 2026, Centene reported 25.9 million managed-care members and operations across all 50 states.
For individuals and families shopping for Marketplace coverage, Centene primarily offers plans under the Ambetter Health brand. Ambetter provides ACA Marketplace plans with benefits that can include preventive and wellness care, maternity and newborn care, pediatric services, mental health and substance-use treatment, prescription drug coverage and other healthcare services. Centene currently offers Ambetter Health Marketplace plans in 29 states, although specific plans and networks vary by location.
Centene also operates Medicaid health plans across 30 states and provides Medicare coverage through its Wellcare brand. Its Medicaid programs include Medicaid expansion, CHIP, foster care, long-term services and supports and other state-specific programs.
Another area of growth is Individual Coverage Health Reimbursement Arrangements (ICHRAs). Through Ambetter Health Solutions, Centene offers individual health plans designed to work with ICHRAs, giving participating employees greater flexibility in selecting coverage that fits their healthcare needs.
Centene's local-market approach means that coverage, premiums, provider networks, deductibles, copayments and benefits can differ significantly between states. Customers should therefore compare the specific plan available in their ZIP code and review the applicable Summary of Benefits and Coverage before enrolling.
