Oct. 4, 2011: Barker meets with his then-boss, Kevin Sass, chief executive officer for Doctors Hospital. According to the lawsuit, Barker tells Sass about the alleged issues he uncovered with medical documentation of office visits, including that many of the medical oncologists patient encounter forms did not support the claims submitted on their behalf.
