A cardiologist with offices in South Paterson allegedly received a $500,000 loan and a trip to Florida for referring patients to a medical lab in Parsippany that made millions of dollars, according to acting U.S. attorney William Fitzpatrick.

Aiman Hamdan (pictured), 50, of Wayne, was charged for allegedly accepting bribes in exchange for test referrals to now-defunct Biodiagnostic Laboratory Services of Parsippany. His wife, Kristina Hamdan, 39, and another doctor Yousef Zibdie, 53, also of Wayne, were charged for their alleged role in the scheme.

A federal grand jury returned a 16-count indictment charging all three with taking bribes, wire fraud, and other violations.

Hamdan allegedly received bribes, a $500,000 loan, a trip to Florida on a private jet for fishing and visiting strip clubs in exchange for generating millions of dollars of patient referrals to the lab from September 2008 to April 2013, authorities said. His wife is accused of paying bribes to several doctors through a sham entity that also paid their household and personal expenses, authorities said.

She allegedly bribed Zibdie, a doctor of internal medicine with a practice in Woodland Park, in exchange for generating more than $900,000 in business for the lab. Hamdan and Zibdie are the fifth and sixth doctors indicted in connection with the lab bribery scheme, authorities said.

The indictment of the three is just the latest in a sweeping bribery investigation that has resulted in 45 guilty pleas including 31 from doctors. This investigation represents the largest number of medical professionals ever prosecuted in a bribery case, authorities believe.

Organizers of the scheme have admitted it involved millions of dollars in bribes that led to more than $100 million in payments to the lab from Medicare and private insurance companies. Authorities to date have recovered more than $12 million through forfeiture. In June 2016, authorities seized all the assets of the lab through forfeiture, authorities said.
