Value sets are essential in activities such as electronic clinical quality measures (eCQM) and patient cohort definition. Creation and maintenance of value sets is labor intensive and error prone. Our method aims to use existing inter-terminology maps to improve the quality of value sets that are defined in more than one terminology. For 197 eCQM value sets defined in SNOMED CT plus ICD-9-CM and/or ICD-10-CM, the map-generated codes showed good overlap with the value set codes. Manual review showed that some new codes identified by mapping should probably be included in the value sets. This could potentially augment the ICD-9-CM codes by 45% (1.5 codes), ICD-10-CM codes by 25% (1.8 codes) and SNOMED CT codes by up to 42% (4.8 codes) per value set on average. The mapping between SNOMED CT and ICD-10-PCS did not perform as well because of the granularity discrepancy in the map.
