Notice of Upcoming RxNorm Data Changes

As a courtesy to users, this section provides advance notice of possible upcoming RxNorm data changes. More information about each change will be provided or repeated in the future. Please note that planned data changes and timelines may change if issues arise.

  • Reminder: Deleting UMLS Metathesaurus UMLSAUI & UMLSCUI in the RxNorm November 2020 Monthly Release
    • The Unified Medical Language System (UMLS) atom unique identifier (AUI) and concept unique identifier (CUI) will not exist in RxNorm beginning with the November 2020 release. In other words, the UMLSAUI and UMLSCUI attributes will be deleted from the RxNorm terminology in the RXNSAT.RRF file. Users can obtain the UMLSAUI and UMLSCUI directly from the Metathesaurus if needed.
