MDS 3.0 RAI Manual
The PDF file labeled “MDS3.0RAIManualv1.17R.Errata.v2,” available in the Downloads section below, contains revisions to pages in Chapter 3, Section I, of the Minimum Data Set (MDS) 3.0 Resident Assessment Instrument (RAI) Manual v1.17.1R that clarifies the need for a detailed evaluation and appropriate diagnostic information to support a diagnosis, such as for a mental disorder, prior to coding the diagnosis on the MDS, and the steps that may be necessary when a resident has potentially been misdiagnosed. An example of when a diagnosis should not be coded in Section I due to lack of a detailed evaluation and appropriate diagnostic information to support the diagnosis has also been added to this section.
Changed manual pages are I-12 and I-16 and are marked with the footer “October 2019 (R).”
The errata document begins with a table that lists all identified revisions and the pages to which they have been applied. Following the table are the actual corrected replacement pages for insertion into the printed manual.
