The lion's share of the money recovered by the DOJ last year came from civil actions taken against individuals or entities the department accused of defrauding Medicaid, Medicare, or other federal health programs with false claims. The feds got $1.9 million out of settlements and judgments related to such cases in 2015.

The department, no doubt sending a warning to would-be fraudsters, touted the way in which new technology has made detecting fraud easier. Software equipped with algorithms that identify claims trends for “known fraud patterns” allows investigators to quickly zero in on likely abuse.

In addition, the Patient Protection and Affordable Care Act (PPACA) put in place new safeguards to ensure that the 1.6 million Medicare providers and suppliers are legitimate. The Centers for Medicare and Medicaid Services halted the enrollment in Medicare of roughly half a million would-be suppliers and providers, insisting that they submit more information.

“CMS also revoked more than 34,000 enrollments meaning, these providers were barred from re-entering the Medicare program for one to three years,” said the statement. “These enhanced screening and enrollment requirements have led to more than $2.4 billion in estimated Medicare savings since 2010.”
