Last week, Senate Finance Committee members Hatch (R-UT) and Coburn (R-OK) sent a letter to HHS Inspector General Levinson requesting documents related to a new system of "predictive analytics" that CMS is using to detect Medicare fraud. CMS was required to estimate savings from its use of predictive analytics and then certify that estimate with the inspector general. According to the letter, "Given the high level of interest in this report and the importance of the results as an indicator of future use and reliance of these efforts, we are very interested in obtaining more information concerning HHS-OIG's review of the report and validation of its findings." The senators asked the inspector general's office for documents it used to evaluate CMS's projection, with a response requested by Nov. 2.
