Who: Dr. Emad Rizk, 51
New role: President and CEO of Accretive Health, a Chicago-based revenue-cycle and collections company, effective July 21. The firm has struggled with restructuring, executive turnover and an ongoing restatement of its finances, which prompted a delisting this year by the New York Stock Exchange. He replaces Steve Schuckenbrock, who has been CEO since April 2013.
Previous position: President of McKesson Healthcare Solutions since 2003. The division includes revenue cycle, health information technology and accountable care software and services, and the clinical decision-support service InterQual.
