The U.S. Department of Justice recently announced an $18.5 million False Claims Act settlement in a case brought by two whistleblowers against LifeWatch Services Inc., an Illinois-based company. The firm allegedly improperly billed Medicare for ambulatory cardiac telemetry (ACT) services, which, according to the Justice Department’s press release, are “a form of cardiac event monitoring that use cell phone technology to record cardiac events in real time without patient intervention.”
