As private equity extends its reach into health care, evidence is mounting that the penetration has led to higher prices and diminished quality of care, a KHN investigation has found. KHN found that companies owned or managed by private equity firms have agreed to pay fines of more than $500 million since 2014 to settle at least 34 lawsuits filed under the False Claims Act, a federal law that punishes false billing submissions to the federal government with fines. Most of the time, the private equity owners have avoided liability.
