CHICAGO – An Illinois-based chiropractor was sentenced on Tuesday to 20 months in federal prison and ordered to pay a $25,000 fine and more than $500,000 in restitution for defrauding insurance providers, including Amtrak’s, by submitting false claims for treatment that was not provided.


According to court documents, John Kosloski, 57, billed private insurers from 2010 to 2017 for services that he purportedly provided to Amtrak employees and their family members, knowing that he was not actively treating them or had never seen them as patients. To further his scheme, Kosloski obtained personal identifiable information of former Amtrak employees or that of their dependents in exchange for cash kickbacks he provided to the employees. Amtrak incurred a loss of approximately $504,347 as a result of Kosloski’s crimes.


In addition to the Amtrak Office of Inspector General, the U.S. Attorney’s Office, Northern District of Illinois, and the FBI supported the joint investigation.
