In recent years, the Obama administration has added manpower to investigate cases, increase audits and analyze more data to fight fraud in the taxpayer-funded Medicare program. Yet a report from the U.S. Senate Special Committee on Aging criticized the government for not targeting its resources more effectively. Improper payments within Medicare’s largest sector increased for the first time in five years, jumping from $30 billion to $36 billion, despite the Obama administration’s all-out campaign to prevent fraud. Medicare fraud in the fee-for-service program had steadily declined since 2009, but improper payments rose between 2011 and 2012, according to the report that cites the most recent data available. During that same time, federal health officials launched a $77 million technology screening system designed to proactively prevent fraudulent providers from at bing joining the system and prevent bogus claims from being paid in the first place.
