Medicaid and CHIP have helped millions of children access preventive care at no cost to families. The Affordable Care Act (ACA) takes this commitment further by removing cost and coverage barriers that could deter families from taking full advantage of preventive care services in private insurance plans. Since becoming law, the ACA has helped maintain or improve access to preventive services for more than half of America’s children (54.1%). By removing financial barriers, the Affordable Care Act is helping more Americans access preventive care, which should result in better health care outcomes and a more effective use of health care dollars. In honor of the ACA’s second anniversary, the following fact sheet looks at its success in protecting and improving access to preventive care for children.
