Transformed Medicaid Statistical Information System (T-MSIS)

With the on-going changes to the national health care environment, the Centers for Medicare & Medicaid Services (CMS) has made significant investments to meet the organizational and information technology (IT) infrastructure to adequately represent CMS’ role in the healthcare marketplace. The Transformed Medicaid Statistical Information System (T-MSIS) is a critical data and systems component of the CMS Medicaid and CHIP Business Information Solution (MACBIS).

CMS has been working with states to transform our MSIS system, which was used to collect utilization and claims data as well as other key Medicaid and CHIP program information, to keep pace with the data needed to improve beneficiary quality of care, assess beneficiary to care and enrollment, improve program integrity, and support our states, the private market, and stakeholders with key information.

The T-MSIS data set contains:

  • Enhanced information about beneficiary eligibility
  • Beneficiary and provider enrollment
  • Service utilization
  • Claims and managed care data
  • Expenditure data for Medicaid and CHIP

Learn more in the T-MSIS State Health Official and T-MSIS State Medicaid Director letters, as well as the T-MSIS Data Dictionary.

There are multiple factors that have influenced the T-MSIS timeline such as: 

  • Federal technical and operational readiness, and states’ technical readiness
  • Quality and completeness of states’ data
  • States’ competing priorities (e.g. ICD-10 conversion, system replacements, expansion preparations, waivers and vendor performance etc.)
