Fifty-five-year-old Dr. Harold Persaud of the Cleveland suburb of Westlake is accused of performing unnecessary tests, heart catheterizations and stent insertions. He also is accused of referring patients for coronary bypass surgeries they didn't need.
An indictment says Persaud engaged in the scheme between February 2006 and June 2012.
He faces 16 counts, including one count of health care fraud and 14 counts of making false statements. A news release from the U.S. attorney's office in Cleveland says Persaud's overbilling resulted in $1.5 million in illegal payments.
Persaud's attorney says he denies the charges and has given patients quality care.
