Updated COVID-19 Provisional Codes in VSAC (ICD10PCS, LOINC)

The National Library of Medicine (NLM) Value Set Authority Center (VSAC) has updated VSAC with the most recent provisional terminology codes published by ICD-10-PCS and LOINC® in response to the COVID-19 pandemic.

These new ICD-10-PCS codes and LOINC pre-release special use provisional codes were developed 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.


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.
