Los Angeles Times columnist Michael Hiltzik writes that lawsuits filed earlier this year by insurers Aetna and United Healthcare alleging fraudulent overcharges by a Northern California chain of small surgical clinics are an "admission" of the insurers' "utter incompetence in handling their most important role under" the health reform law, "which is keeping a lid on health care costs." He concludes, "If the insurers continue to perform this badly, who will pay the price? As taxpayers and policyholders, you will."
