Federal law enforcement officials announced what they called the largest healthcare fraud case in the nation’s history, indicting a Dallas area physician for allegedly bilking Medicare for nearly $375 million in billings for nonexistent home healthcare services.

Top Justice Department officials, working for several years to stem a rampant rise in healthcare fraud around the country, also revealed Tuesday that 78 home health agencies that were working with the physician, Dr. Jacques Roy, will be suspended from the Medicare program for up to 18 months.

FBI agents in Texas arrested Roy, of Rockwall, Texas, a physician for 28 years, and asked a federal judge in Dallas to keep him in custody until trial, citing his vast “bank accounts, a sailboat, vehicles and multiple pieces of property” as indications he may attempt to flee.

Facing life in prison and a $250,000 fine, as well as restitution of the vast sum of money he allegedly cost the federal government, Roy is to appear in court in Dallas later Tuesday.
