NLM released VSAC update version 2.16.6 on May 14, 2018
New code systems in VSAC
- Unique Ingredient Identifier (UNII) : The joint FDA/USP Substance Registration System (SRS) generates unique ingredient identifiers (UNIIs) for substances in drugs, biologics, foods, and devices.
- Common UCUM Units: LOINC® translation table that enumerates the Unified Code for Units of Measure (UCUM) syntax for many common unit patterns currently used in electronic reporting.
- Medication Reference Terminology (MED-RT): The evolutionary successor to the Veterans Health Administration's (VHA) National Drug File-Reference Terminology (NDF-RT). RxNav and RxClass will change because of the NDF-RT to MED-RT transition

Change value set ownership between VSAC authoring groups
If you are no longer associated with a value set you authored, due to personnel or other changes, you may now transfer your value set to a VSAC group who is willing to steward your value set. Both your current VSAC group members and the future owners of your value set must agree in advance. Learn more...
Contact value set stewards directly for questions and feedback
Sometimes you may have questions about the content, purpose or usage of a value set that only the steward can answer. You may wonder when a value set steward intends to update their value set. Select the Contact icon within the value set details of any published value set. For draft value sets in the Authoring tool, select the Contact Steward link in the left side bar.
Remove all codes from a new version of your value set
In some cases, you may wish to exclude all your value set's current codes so that you can easily replace your code list with a different list of codes, perhaps from a different terminology code system, that will serve the same purpose. The original intent and usage of your value set should always be preserved.
