CareSource built its entire business around government-sponsored health programs, starting as an Ohio Medicaid managed care plan in 1989 under founder Pamela Morris and growing into the second largest Medicaid plan in the country. Today the not-for-profit serves more than two million members across states including Arkansas, Florida, Georgia, Indiana, Michigan, Mississippi, Nevada, New York, Ohio, West Virginia and Wisconsin. Product lines cover Medicaid managed care, ACA Health Insurance Marketplace plans you can buy during open enrollment, Medicare Advantage, and dual-eligible options such as MyCare Ohio. Its Dayton roots show in a heavy emphasis on social determinants of health, with programs addressing employment, housing and food access sitting alongside traditional medical management. CareSource’s health plan entities do not carry AM Best financial strength ratings, though AM Best assigned its captive, CareSource Reinsurance LLC, an A- (Excellent) rating in January 2026.
