CMS reports that, overall, the updated data indicate that of all the RAC overpayment determinations (525,133), only 7.6 percent (40,115) were overturned on appeals as of August 31, 2008. As has been widely reported here and elsewhere, RACs succeeded in correcting more than $1.03 billion of Medicare improper payments. Approximately 96 percent of these improper payments were overpayments collected from providers, while the remaining 4 percent were underpayments repaid to providers.
