MDM Decommissioning Notification
Master Data Management (MDM) Announcement

The Master Data Management (MDM) platform is being formally retired as part of CMS’s broader data modernization effort.

This is the first of a series of notifications for all MDM data users and consumers about the decommissioning of the MDM PMI/SPP and NPI Profile provider data products. 

  • The final data refresh of the MDM PMI/SPP and NPI Profile provider data products will occur on November 12, 2026.
  • Effective November 13, 2026, please contact IDR Support for any MDM PMI/SPP and NPI Profile access needs or data inquiries.
  • MDM termination of external data shares and S3 access will take effect November 18, 2026.
  • A snapshot of the final data refresh of the MDM PMI/SPP and NPI Profile provider data products will reside in the IDR by November 18, 2026. 

If your applications, reports, or processes rely on the MDM PMI/SPP and/or NPI Profile data products, please begin planning for this change by contacting the IDR Support team at MDM-IDR-Migration@GDIT.com and the CMS IDR Support team at CMSIDR_Support@cms.hhs.gov to migrate to alternate provider data in the Integrated Data Repository (IDR).

For all MDM questions, please contact the MDM team at MDMTeam@cms.hhs.gov.
