A value set is a list of terms and their codes
derived from single or multiple standard
vocabularies used to unambiguously define
clinical concepts (such as patients with
diabetes, clinical visit, reportable diseases)
used in clinical quality measures and to
support effective health information
exchange, as well as other specific business
purposes.

Contribute to the unambiguous definition of the numerator
and the denominator for a quality measure.

diverse contexts as clinical and comparative effectiveness
research, clinical decision support, performance measurement
and public health
