One of the biggest flash points in the debate over Republican legislation to repeal and replace the Affordable Care Act is the future of Medicaid. Here are some basic facts about the 52-year-old program.



What is Medicaid?

It’s a public health insurance program largely for low-income people, though some middle-class disabled and elderly people also qualify. States and the federal government share the cost.

Whom does Medicaid cover?

■ Nearly one in five Americans, 74 million people, are on Medicaid.

■ Federal law guarantees Medicaid coverage to pregnant women, children, elderly and disabled people under certain income levels.

■ It covers more than a third of the nation’s children and pays for half of all births.

■ It also covers almost two-thirds of nursing home residents, including many who are middle class and spent of all their savings on care before becoming eligible.
