T-MSIS Data Not Yet Available for Overseeing Medicaid

In 2016, the Federal Government and States spent $574 billion on Medicaid, serving more than 74 million enrolled individuals. Complete, accurate, and timely Medicaid data are vital for the effective administration and oversight of the Medicaid program by States and the Federal Government. Historically, problems with Medicaid data have hindered program integrity, research, budgeting, and policy. Consequently, OIG has designated the improvement of Medicaid data as a top management challenge facing the Department of Health and Human Services. The Transformed Medicaid Statistical Information System (T-MSIS) is a new data system intended to improve the completeness, accuracy, and timeliness of Medicaid data.
