Welcome to the NLM Value Set Authority Center (VSAC)


For VSAC announcements, please subscribe to the VSAC Updates listserv.


The Value Set Authority Center (VSAC) is provided by the National Library of Medicine (NLM), in collaboration with the Office of the National Coordinator for Health Information Technology and the Centers for Medicare & Medicaid Services.


The VSAC provides downloadable access to all official versions of vocabulary value sets contained in the 2014 Clinical Quality Measures (CQMs). Each value set consists of the numerical values (codes) and human-readable names (terms), drawn from standard vocabularies such as SNOMED CT® , RxNorm, LOINC and ICD-10-CM, which are used to define clinical concepts used in clinical quality measures (e.g., patients with diabetes, clinical visit).


The content of the VSAC will gradually expand to incorporate value sets for other use cases, as well as for new measures and updates to existing measures.


Viewing or downloading value sets requires a free Unified Medical Language System® Metathesaurus License, due to usage restrictions on some of the codes included in the value sets.


The Data Element Catalog contains the complete list of 2014 CQMs and value set names.

Value Set Information Available Updates:   Expansion Versions Expansion Version is an alphanumeric string label. Value Set Expansions exist only in the "Search Value Sets" tab (the public repository). VSAC computes value set expansions from the value set definitions, created by authors in the "VSAC Authoring Tool," using an author-designated expansion profile of specified code system versions. The default expansion profile (VSAC Auto Expansion) consists of the most recent code system versions available in VSAC. In other words, value set expansions are snapshots-in-time of value set definitions computed by VSAC using a specified code system version.

The value set definition will include the name, code system, purpose statements, and the codes. The codes may be author-defined as an enumerated list of codes, or the codes may be author-defined intensionally as a logical statement (all codes that are children of this code).:
