*The “VSAC Code System Version” designation is a VSAC-created element based on the VSAC acquisition date of the provisional codes. Each VSAC provisional code system version contains all provisional codes, cumulatively, until the terminology incorporates their provisional codes into a formal release.

Be aware that downstream users may not be ready to handle prerelease codes until they are published in an official terminology release.

The SNOMED CT US Edition 20200301 included COVID-19 related codes in the formal release. The INTERIM March 2020 International Edition release, created as part of the ongoing global effort to tackle the Coronavirus outbreak, provided updated Coronavirus descriptions for Members and implementers. VSAC updated the SNOMED CT US Edition 20200301 descriptions accordingly, on 04/03/2020. See SNOMED CT COVID-19 Related Content--Released & Published Content.
