Embattled hospital revenue management company Accretive Health Inc. has replaced longtime Chief Executive Mary Tolan with Stephen Schuckenbrock, former president of Dell Services, the company said Tuesday. Tolan will become chairman of Accretive's board, where she will continue to work with the company's customers and court new prospects, she said in a brief conference call with analysts. The move to replace Tolan comes at a difficult time for Chicago-based Accretive, which has not reported fourth-quarter 2012 financial results. The company said last month that it booked revenue for certain contracts incorrectly for at least nine quarters and will restate all quarterly financial statements going back to the second quarter of 2010.
