More than one in four Americans—54 million people—could lose health insurance due to pre-existing conditions, without the protections of the Affordable Care Act (ACA). That analysis comes from a new study from the Kaiser Family Foundation (KFF).

The report is an update of a 2016 analysis which found that 27 percent of American adults under 65, at that time equaling 52 million people, would not qualify for insurance under pre-existing condition exclusions prior to the ACA. The percentage today remains 27 percent, based on data about pre-existing conditions drawn from the National Health Interview Survey.
