Due to the public health emergency of the COVID-19 pandemic, the National Library of Medicine (NLM) Value Set Authority Center (VSAC), in agreement with specific terminology providers, has responded to public requests to remove the UMLS License login requirements from known COVID-19 related value sets in VSAC. The terms of the UMLS License Agreement still apply to the content of these value sets.
All value sets in VSAC are authored and maintained by external subject matter experts and are not reviewed or governed by NLM.
Please contact us if you are aware of any additional COVID-19 related value sets in VSAC that you believe should be added to this login-free set.
The current list of login-free COVID-19 value sets is hosted here: https://www.nlm.nih.gov/vsac/support/usingvsac/covid19valuesets.html
