On Nov. 17, the Justice Department secured the denaturalization of Marieva Briceno, who defrauded more than $5.4 million from Medicare and then obtained US citizenship by concealing her crimes from immigration officials. A native of Venezuela, Briceno owned three purported medical clinics in the Detroit, Michigan, area that paid individuals on Medicare to undergo unnecessary tests and procedures. From May 2007 to January 2010, Briceno and her co-conspirators submitted approximately $5,460,323 in fraudulent claims to Medicare for those medically unnecessary services. Ultimately, Medicare paid $2,998,321.94 on those fraudulent claims, with Briceno personally receiving approximately $513,200 in fraudulent payouts.
