Centers for Medicaid and CHIP Services (CMCS)

Transformed Medicaid Statistical Information System (T-MSIS)
T-MSIS Data Dictionary Crosswalk (Change Log) - Version 4.0.0 to Version 4.1.1
Last Modified: 2026-05-29

PRA Disclosure Statement: The Transformed Medicaid Statistical Information System (T-MSIS) is used to assist the Centers for Medicare & Medicaid Services (CMS) with monitoring
and oversight of Medicaid and CHIP programs, to enable evaluation of demonstrations under section 1115 of the Social Security Act and to calculate quality measures and other metrics, including those reported
through the new Medicaid and CHIP Scoreboard. Section 4735 of the Balanced Budget Act of 1997 included a statutory requirement for states to submit claims data, enrollee encounter data,
and supporting information. Section 6504 of the Affordable Care Act strengthened this provision by requiring states to include data elements the Secretary determines necessary for program integrity, program
oversight, and administration. Under the Privacy Act of 1974 any personally identifying information obtained will be kept private to the extent of the law. According to the Paperwork Reduction Act of 1995,
no persons are required to respond to a collection of information unless it displays a valid OMB control number. The valid OMB control number for this information collection is 0938-0345 (Expires: 11/30/2027).
The time required to complete this information collection is estimated to average 11.25 hours per response, including the time to review instructions, search existing data resources, gather the data needed,
and complete and review the information collection. If you have comments concerning the accuracy of the time estimate(s) or suggestions for improving this form, please write to:
CMS, 7500 Security Boulevard, Attn: PRA Reports Clearance Officer, Mail Stop C4-26-05, Baltimore, Maryland 21244-1850.
