A ring of Medicare fraudsters used Miami-Dade courts for years to execute a $63 million health insurance scam, according to information from the U.S. Department of Justice.

The group coordinated with criminal defendants in the Miami-Dade state court system, helping them avoid incarceration by securing court orders for mental health treatment, according to documents filed in federal court. It then referred the defendants to Greater Miami Behavioral Healthcare Center Inc., a community mental health center that has since shuttered.
