Killing the Affordable Care Act (ACA) Medicaid expansion program along with the ACA public exchange system could have a significantly bigger effect on the U.S. uninsured rate than simply killing the ACA public exchange system.

Matt Buettgens and other analysts at the Washington-based Urban Institute, a nonprofit research center commonly viewed as being supportive of the ACA, have analyzed the possible effects of killing the big ACA health coverage expansion programs in a new paper.
The ACA exchange system gives consumers with incomes from 100 percent to 400 percent of the federal poverty level the ability to use federal tax credit money to pay for health coverage.
The ACA Medicaid expansion program provides federal cash states can use to get low-income childless adults enrolled in Medicaid.
Buettgens and his colleagues predict in the paper that eliminating the two programs would increase the number of uninsured people in the United States to 53.5 million in 2021, from about 30 million if the exchange and Medicaid expansion programs stay in place.
Federal Medicaid spending would drop to $286 billion, from $364 billion, but states would reduce their share of Medicaid spending by just $11 billion, to $208 billion, the analysts estimate.
For a look at some numbers showing how the analysts think saving Medicaid expansion, but killing the exchange system, might affect the U.S. health care system in 2021, read on:

By the numbers
U.S. residents ages 65 and older already qualify for Medicare, a nearly universal health coverage program for the elderly.
