In all, the fraudulent billings allegedly totaled USD 900 million, the Justice Department said. Authorities called it the largest-ever national Medicare fraud dragnet.
The Justice Department says the defendants billed for care that was not necessary or services that were not rendered.

While the individual cases may be unrelated, law enforcement agencies often coordinate the announcement of health fraud charges and arrests to send a message to fraudsters and the general public alike. Health care fraud costs tens of billions of dollars annually.
