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

These pre-release special use provisional codes were developed by LOINC in response to the COVID-19 pandemic and they are based on the most up to date information available at the time of their creation.
