From 2009 through to 2011 Khanna owned and operated his own medical practice, Family Medicine and Pediatrics LLC, according to court documents.
He agreed with representatives of a diagnostic testing facility called Orange Community MRI LLC (Orange MRI) that he would be paid cash in exchange for patients he referred for testing.
He received cash kickbacks from Orange MRI for diagnostic tests performed on Medicare and Medicaid patients and met with an Orange MRI representative at his office on October 4, 2011, and November 10, 2011, taking envelopes with cash, according to the documents.
Khanna acknowledged taking kickbacks from Orange MRI on other occasions as well, federal prosecutors said.
