While nearly all states are now reporting to a national repository for Medicaid data, the data are not sufficient to provide effective oversight of the program, according to a new audit by the Government Accountability Office.
Data from the Transformed Medicaid Statistical Information System (T-MSIS) was meant to enhance the ability of federal administrators to identify potential fraud while improving program efficiency. However, GAO auditors report that despite the fact that 49 states had begun reporting T-MSIS data as of this past November, an estimated $36.7 billion in payment errors were still made in 2017.
