The $1.3 billion was from a single fraud ring not overall Medicare fraud. That was merely one investigation that netted 400 individuals. In 2015 it was reported that Medicare fraud for the previous year was a $60 Billion of a $600 billion Program while in 2016 it was reported that $140 Billion in "improper payments" were paid on the Medicaid program or 12% of the total program. Oh, and the rate of improper payments on Medicaid has almost doubled in the last few years. So across both programs, $200 billion in fraudulent/improper payments in approximately one year.
