How a successful Colorado startup turned into a nearly $1 billion health care fraud scheme

Zynex Medical, a Colorado-based medical device manufacturer, has been hit with federal indictments alleging a massive health care fraud scheme totaling nearly $1 billion. The company, which specialized in electrotherapy devices, reportedly engaged in aggressive and fraudulent billing practices that inflated its revenue figures for years. Once a darling of the Colorado tech and health scene, the company's stock has plummeted as federal investigators detail a sophisticated operation designed to defraud insurance providers and government health programs. The indictment marks a dramatic fall for the public company that had previously reported hundreds of millions of dollars in annual revenue.
