A former top executive with Tustin (CA) Hospital and Medical Center has agreed to plead guilty to paying illegal kickbacks for patients recruited from skid row in Los Angeles, according to papers filed in federal court. Vincent Rubio was the hospital's chief financial officer when authorities raided the facility two years ago during an investigation into an alleged multimillion-dollar scheme to defraud Medicare and Medi-Cal. Authorities contended that the hospital recruited thousands of homeless people to undergo unnecessary medical tests and procedures, the Los Angeles Times reports.
