Rhode Island is receiving more than a quarter-million-dollars to help prevent Medicare and Medicaid fraud.  The funding from the Department of Health and Human Services money will be used to educate recipients on how to defend against Medicare and Medicaid fraud.  In many cases officials say the schemes are presented as free services to seniors, but they come with a steep cost for taxpayers.  It's estimated that this type of fraud costs taxpayers across the country 60-billion-dollars a year.
