According to a new analysis by the Department of Health and Human Services, 50 to 129 million (19 to 50 percent of) non-elderly Americans have some type of pre-existing health condition. Up to one in five non-elderly Americans with a pre-existing condition — 25 million individuals — is uninsured. Under the Affordable Care Act, starting in 2014, these Americans cannot be denied coverage, be charged significantly higher premiums, be subjected to an extended waiting period, or have their benefits curtailed by insurance companies.
