A new law passed in the recent Tennessee legislative session should help state officials cast a wider net in going after potential fraud against TennCare, including healthcare providers that charge for services that never took place. Under the law, TennCare would use proceedings before an administrative law judge to pursue cases that involve less than $10,000 of suspected fraud. That would allow the state's attorney general to focus on larger, more serious cases that have to go through the federal court system where the process is more time-consuming.
