Fraud is a serious problem that robs Medicare of hundreds of millions of dollars every year. Reducing this fraud is no simple matter. Medicare is the largest health program in the United States, and it generates more transactions annually than can be reasonably investigated for fraud.
In order to detect and prosecute this fraud, the US is highly dependent upon whistleblowers who are willing to report Medicare fraud and provide the evidence necessary to bring cases forward. To encourage whistleblowing, the US relies on a law known as the False Claims Act (FCA).
