T-MSIS, which stands for Transformed Medicaid Statistical Information System, is an expansion of the existing Centers for Medicare & Medicaid (CMS) MSIS extract process. T-MSIS is mandated by CMS and the Affordable Care Act (ACA), and is a natural extension of current Decision Support Systems (DSS) and data warehouse solutions in state agencies today.
As part of the CMS plan to improve and expand upon its Medicaid data repository, states are required to augment the current MSIS data extracts. Currently, each state submits five MSIS extracts to CMS on a quarterly basis. These data are used by CMS to assist in federal reporting for the Medicaid and Children’s Health Insurance Program (CHIP). Several reasons culminated in the CMS mission to improve the repository, including incomplete data, questionable results, multiple data collections from states, multiple federal data platforms, and analytic difficulties in interpreting and presenting the results. In addition, timeliness issues have prompted CMS to re-evaluate its processes and move toward a streamlined delivery, along with an enhanced data repository.
The new T-MSIS extract format and frequency is expected to further CMS goals for improved timeliness, reliability, and robustness through monthly updates and an increase in the amount of data requested. .
