What is a Value Set?
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.

Use Cases for Value Sets/VSAC
• Initial: “Meaningful Use” 2014 Clinical Quality Measures • Contribute to the unambiguous definition of the numerator
and the denominator for a quality measure.Example: #diabetes patients/specific population
• Future/Phase 2: In collaboration with the field, support exchange and analysis of data within and between such diverse contexts as clinical and comparative effectiveness research, clinical decision support, performance measurement and public health
