In February 2008, New York State Attorney General Andrew Cuomo announced an industry-wide investigation into a scheme by health insurers to defraud consumers by manipulating reasonable and customary rates. The announcement included a statement that Cuomo intended "to file suit against Ingenix, Inc., its parent UnitedHealth Group, and three additional subsidiaries." Cuomo asserted that his investigation found that rates found in a database of health care charges maintained by Ingenix were lower than what he determined was the actual cost of certain medical expenses. Cuomo said this inappropriately allowed health insurance companies to deny a portion of provider claims, thereby pushing costs down to members.
