Value Set Authority Center
• Provides downloadable access to all official versions of vocabulary value sets contained in the 2014 CMS Clinical Quality Measures (CQMs).
• Because many of the clinical terminologies used by value sets have copyright restrictions, VSAC users are required to agree to the terms of the UMLS License.

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

• As currently represented in the VSAC, value sets are closely tied to specific measures (CQM).
• Value set developers currently include such organizations as • National Committee for Quality Assurance• AMA (Physician Consortium for Performance
Improvement)• CDC • CMS
