An Atlantic County doctor Brian Sokalsky, 46, of Margate was sentenced to 15 months in prison Tuesday for defrauding New Jersey state and local health benefits programs and other insurers by submitting fraudulent claims for medically unnecessary prescriptions, U.S. Attorney Vikas Khanna said. Sokalsky previously pleaded guilty before U.S. District Judge Robert B. Kugler to one count of conspiring to commit health care fraud. U.S. District Judge Edward S. Kiel sentenced Sokalsky in Camden federal court.
