The SNF data validation process assesses the accuracy of Minimum Data Set (MDS)-based quality measures used in the SNF Value Based Purchasing (VBP) and Quality Reporting Programs (QRPs). The SNF data validation process has been established in response to Section 1888(h)(12) of the Social Security Act that requires the Secretary to apply a data validation process to SNF VBP and QRP measures. In the SNF Prospective Payment System (PPS) fiscal year (FY) 2024 final rule (CMS1779-F) and FY 2025 final rule (CMS-1802-F), CMS specified that a data validation process for MDSbased measures would be implemented to ensure accurate quality data beginning with the FY 2027 program year/FY 2025 performance period.
