In the five years he served as U.S. Attorney for the Eastern District of Tennessee, Bill Killian oversaw dozens of healthcare fraud cases. By the time he resigned from his post Dec. 5, Killian’s district had collected more than $200 million from healthcare fraud cases during his tenure.In his new position with the national law firm Polsinelli, Killian (right) will continue focusing on civil and criminal fraud cases through the firm’s government investigations and compliance practice. Killian says that although enforcement numbers are continually rising, healthcare fraud is not any more prevalent now than it was in previous years–the government is just getting better at detecting it. Thanks to better detection methods, Killian says his office saw civil fraud claims increase five-fold over the course of his tenure as U.S. Attorney.
