In a string of qui tam lawsuits, Phillips & Cohen clients alleged that various medical labs were billing Medicare for blood tests that doctors hadn't ordered and weren't medically necessary. Lawsuits brought by the firm recovered nearly $200 million for the government. The firm's first lawsuit in this area resulted in the government launching "Labscam," an investigation into the lab industry. The investigation and qui tam lawsuits returned more than $800 million to the federal government and according to an economic analysis deterred false claims that could have cost the Medicare program billions of dollars.
