What's New –

November 24, 2023

Errata V3.01.4 for MDS Data Specifications V3.01.1 (FINAL) is now available for download under the Downloads section at the bottom of this webpage.  Six issues were added to the errata. As a result, four edits were revised, and there were several mapping changes of items to edits. These revisions will be implemented in production on December 12, 2023, but they will be RETROACTIVE, so modifications to assessments submitted between October 1, 2023 and December 12, 2023 will have the edit and mapping changes from these issues applied in assessment validation.

The “PDPM Grouper JAR Package V2.2001.zip” is now available in the Downloads section below. This V2.2001 release is an update to adjust the OBRA logic for target dates on or after October 1, 2023.   

The logic for standalone OBRA assessments will be similar to the interim payment assessments logic.

This means that: 

    If A0310A=01 and A0310B=99, use column 1 (GGxxxxx1) 

    If A0310A=02-06 and A0310B=99, use column 5 (GGxxxxx5) 

This change will affect Nursing, Occupational Therapy, and Physical Therapy logic.
