There are serious concerns about fraud in autism services, particularly in Minnesota where 85 centers are under investigation for potential fraud, waste, or abuse. Recent prosecutions revealed schemes like hiring unqualified staff and billing for unprovided services. HHS also found up to $600 million in "improper" payments for autism services across four states.
