Value set

A value set is a list of specific values, terms, and their codes, used to describe clinical and administrative concepts in the quality measures. Value sets provide groupings of unique values along with a standard description or definition from one or more standard vocabularies used to describe the same clinical concept, e.g., diabetes, clinical visit, demographics, within quality measures. Examples of such standard vocabularies that are used to support effective, interoperable health information exchange include SNOMED CT, RxNORM, and Logical Observation Identifiers Names and Codes (LOINC).
