The Pennsylvania attorney general’s office has charged a co-founder and former executives of an addiction treatment firm and accused them of profiting off addicts by fraudulently billing insurance companies for tens of millions of dollars. The charges announced Monday by Attorney General Josh Shapiro against 11 people and nine corporations focus on Liberation Way, a for-profit treatment company. The firm that bought a majority stake in Liberation Way in 2017 says the staff has been overhauled.
