The National Library of Medicine (NLM) Value Set Authority Center (VSAC) has updated VSAC with the most recent provisional terminology codes published by LOINC® and SNOMED CT, in response to the COVID-19 pandemic.

These terminologies developed and published these codes to streamline the public health response to the SARS-CoV-2 virus and the COVID-19 disease, and they are based on the most up to date information available at the time of their creation



Value set authors who create COVID-19 related value sets can Contact NLM to request their COVID-19 value sets be included in a prefiltered VSAC search.
