A new report by the Government Accountability Office “finds that state and federal officials failed to detect millions of dollars in Medicaid prescription drug abuse,” USA Today reports. “An audit of the government program in five large states found about 65,000 instances of beneficiaries improperly obtaining potentially addictive drugs at a cost of about $65 million during 2006 and 2007 — including thousands of prescriptions written for dead patients or by people posing as doctors.”
