Now Available: Final MDS 3.0 RAI User’s Manual Version 1.18.11

The final Minimum Data Set (MDS) 3.0 Resident Assessment Instrument (RAI) User’s Manual version (v)1.18.11 is now available in the Downloads section on the Minimum Data Set (MDS) 3.0 Resident Assessment Instrument (RAI) Manual page. The MDS 3.0 RAI User’s Manual v1.18.11 will be effective beginning October 01, 2023.

This version of the MDS 3.0 RAI Manual contains substantial revisions related to the Improving Medicare Post-Acute Care Transformation Act of 2014 (IMPACT Act), which requires that standardized assessment items be collected across post-acute care (PAC) settings. Standardized data will enable cross-setting data collection, outcome comparison, exchangeability of data, and comparison of quality within and across PAC settings. Additionally, the language of the manual has been updated throughout to be gender neutral. Guidance and examples in numerous chapters and appendices have been revised for clarification and to reflect current regulations and best practices. Due to the scope of the revisions, CMS will not issue Replacement Pages for v1.18.11; those wishing to continue using a physical copy of the manual are encouraged to print the new version.

A document listing all changes from the MDS 3.0 RAI Manual v1.18.11 draft version to the final version is available for reference in the Downloads section on the Minimum Data Set (MDS) 3.0 Resident Assessment Instrument (RAI) Manual page.
