Value sets, also referred to as code groups, help healthcare providers and payers define clinical concepts.
Each value set is essentially a bag of codes that can represent a particular disease or a type of medicine. A value set consists of terms and their associated numerical codes, which are taken from standard terminologies such as ICD-10, SNOMED CT®, RxNorm and LOINC®. Value sets have a number of use cases. Those include creating Clinical Quality Measures (CQMs), defining a patient population cohort, defining decision support rules, and developing application pick lists.
