Former N.J. physician sentenced for billing fraud

A U.S. District Court judge in Newark, N.J., this week sentenced a former physician to six and a half years in federal prison for fraudulently diagnosing patients with heart ailments and ordering them to undergo unnecessary tests. The physician reportedly defrauded Medicare, Medicaid and private insurers of $19 million. Jose Katz, a former professor at Columbia University who once had offices in northern New Jersey and New York City, pleaded guilty in April.
