Data Changes

Qualitative Distinction
Qualitative Distinction modifiers allow flexibility in the RxNorm model to create new RXCUIs as needed. See the RxNorm Technical Documentation for more information about Qualitative Distinctions (QDs), which were first released in the August 2016 monthly release.

Here are the new concepts with QDs in the April 2019 release:

  • 20/80 Release

REMINDER: Eliminating Two Weekly Releases
RxNorm will be eliminating 2 weekly releases beginning in 2019. The May 1, 2019 and October 30, 2019 weekly releases will not be created this year. The two eliminated weekly releases will immediately precede the full May and November monthly releases moving forward. Please note that there will now be 50 RxNorm weekly releases instead of 52.
