CHIP stands for the Children’s Health Insurance Program. It provides health coverage to eligible children, through both Medicaid and separate CHIP programs. CHIP is administered by states, according to federal requirements. The program is funded jointly by states and the federal government.
The Medicaid.gov website says that 8.9 million children were enrolled in CHIP (according to 2016 statistical enrollment data). Eligibility is based on income. It covers uninsured children up to age 19 in families with incomes too high to qualify them for Medicaid. CHIP also covers pregnant women who meet income eligibility requirements. In 2010, the Affordable Care Act extended CHIP eligibility to state employee’s children (who previously were not eligible, regardless of income.)
Here is what happened when the United States Congress failed to renew funding for CHIP in 2017.
