The Validation Utility Tool (VUT) is a software utility that can be used to validate MDS 3.0 submission files in XML format. The tool enforces the edits that are mapped to the MDS 3.0 items as published in the MDS 3.0 Data Specifications.

The v3.5.0 VUT continues to support older data specification versions and has been updated to incorporate Issues 17 in Errata v3.00.6 to the current Data Specifications, as well as new ICD codes and is in effect on January 1, 2021.

Please note that there are edits which the VUT cannot support because they are edits against existing ASAP system data. The VUT does not interface with ASAP therefore it cannot confirm those edits. The VUT does not currently interface with the RUG III and IV DLLs, or the new PDPM DLLs, therefore it does not recalculate and confirm that Grouper values are correct.
