Prosecutors have announced arrests in a health care fraud case that they say extended to several states.
The U.S. attorney's office says agents on Tuesday arrested the CEO of Chicago-based Mobile Doctors and one of its physicians.
Mobile Doctors operates in six states: Arizona, Illinois, Indiana, Michigan, Missouri and Texas. Its website says its doctors made more than 400,000 house calls since the company's founding in 1996.
Agents executed search warrants at offices in Chicago, Detroit, and Indianapolis. The warrants also sought more than $2.5 million in allegedly fraudulent proceeds.
Prosecutors say the scheme involved fraudulently increasing Medicare bills for in-home visits, including by indicating treatments were more complicated than they were.
Calls to several numbers for Mobile Doctors' Chicago headquarters were not answered Tuesday.
