Children’s Health Insurance Program The Children’s Health Insurance Program (CHIP) was created in 1997 to give health insurance and preventive care to nearly 11 million, or 1 in 7, uninsured American children. Many of these children came from uninsured working families that earned too much to be eligible for Medicaid. All 50 states, the District of Columbia, and the territories have CHIP plans. Affordable Care Act The 2010 Affordable Care Act (ACA) brought the Health Insurance Marketplace, a single place where consumers can apply for and enroll in private health insurance plans. It also made new ways for us to design and test how to pay for and deliver health care. Medicare and Medicaid have also been better coordinated to make sure people who have Medicare and Medicaid can get quality services.
