The U.S. Department of Justice has for years been reliant on whistleblowers, often company insiders, to bring forward allegations of fraud for investigation under the False Claims Act.
But recently the DOJ has openly acknowledged that it has increasingly begun to leverage the government's own insider information, in the form of running sophisticated data analytics on federal health care program billing and claims data "to identify trends and extreme outliers." The DOJ's fiscal year 2020 fraud statistics certainly bear this out, revealing a steep increase in the number of DOJ-initiated FCA suits last year.
