According to this news report, "the former president of WellStar Medical Group believes he was fired to prevent him from going public with alleged billing and revenue improprieties by some WellStar physicians. The health system's attorney denies the allegation. WellStar Health System Interim CEO Jim Budzinski terminated Dr. Richard Lopes on March 21 without cause. WellStar claimed in a press release that Lopes had resigned. Not true, Lopes said in a March 24 letter to Budzinski."
