# Class: ConceptClass 


_The CONCEPT_CLASS table includes semantic categories that reference the source structure of each Vocabulary.  Concept Classes represent so-called horizontal (e.g. MedDRA, RxNorm) or vertical levels (e.g. SNOMED) of the vocabulary structure.  Vocabularies without any Concept Classes, such as HCPCS, use the vocabulary_id as the Concept Class.  This reference table is populated with a single record for each Concept Class, which includes a Concept Class ID and a fully specified Concept Class name._
