The corrupt former president of a New Jersey lab testing firm said hundreds of doctors demanded bribes and kickbacks as part of a $100 million dollar Medicare and insurance billing scheme. Scott Nicoll pleaded guilty and admitted Monday that his Parsippany firm, Biodiagnostic Laboratory Services, paid millions in bribes to doctors in order to bill tens of millions in additional and often unnecessary blood tests sent to his lab. After the court hearing, Nicoll said through his lawyer that hundreds of doctors demanded illegal cash payoffs from the lab in exchange for business.
