HCPro's MDS 3.0 RAI User's Manual has been updated to include the July 2022 revisions to pages in Chapter 3, Section I, of the MDS 3.0 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.
