A Janesville pharmacist is facing federal charges of health care fraud after being accused of receiving about a million dollars from the federal government. 55-year-old Mark Johnson was arrested without incident Friday morning in Janesville, by agents from the U.S. Department of Health and Human Services and the U.S. Postal Inspection Service. Officials say a grand jury issued a 46-count indictment Wednesday in Madison. Johnson is accused of devising a scheme to defraud Medicare and Medicaid from January of 2008 to March of 2014. He was the owner and president of Kealey Pharmacy and Home Care on South Jackson Street at the time. Federal agents raided the pharmacy in Marcy of 2014.
