Humana Inc. settled part of a case in which Kansas City area physicians sued Humana and other health insurance companies for allegedly conspiring to suppress payments to physicians. A class action lawsuit filed in 2005 alleges that the companies violated antitrust laws by fixing prices and engaging in other monopolistic practices, such as refusing to negotiate reasonable reimbursements. Under the settlement, Humana admitted no wrongdoing and agreed to pay $2.8 million in cash, to be distributed among more than 2,200 physicians, and implement initiatives and other commitments with respect to its business practices, the cost of which will have a value of no less than $200,000.
