• UCUM - Regenstrief Institute also maintains the Unified Code for Units of Measure (UCUM) code system, a related standard that includes units of measures being contemporarily used in international science, engineering, and business.
  
• RxTerms - RxTerms is a drug interface terminology derived from RxNorm for prescription writing or medication history recording. CMS is using RxTerms in a demonstration project of its post-acute care assessment tool (CARE), for which a LOINC representation of the assessment tool is also being developed.
