The July 31, 2021 release contains 4,468 new concepts and 8,813 inactivations within SNOMED CT’s 350,000+ concepts. It delivers on SNOMED International’s commitment to make SNOMED CT richer, more precise and more useful to its global users by improving the structural quality of the clinical terminology on an ongoing basis.
The first release reflecting the transition to Concrete Domains, which was previewed in the January 31, 2021 International Edition, the July 31 2021 release contains drug concept strengths and counts expressed as concrete values, which enables users to better express strengths and concentrations of clinical drugs as well as ingredient counts. More details on this transition are provided in the July 31 2021 Release Notes.

Building on past projects and collaborations
This release continues to build on many of SNOMED International’s project-driven and domain-specific collaborations, as well as on requests received from stakeholders. New concepts were recently added to support the SNOMED CT to International Classification for Nursing Practice equivalence product and to support Social Determinants of Health and cancer synoptic reporting.
Working in collaboration with Orphanet
to improve the visibility of rare diseases in terminologies and promote interoperability among different codification and terminology systems, the July 31, 2021 release contains new concepts for the agreed upon original set of prioritized rare diseases. All of the concepts added for the Orphanet project have been mapped to ICD-10. The SNOMED CT to Orphanet Simple Map is set to be published in October 2021 and will be based on the July 2021 International release of SNOMED CT.
The map provided for the July 31, 2021 release now represents a complete map
from SNOMED CT International release to ICD-10 (2016 version): 2,192 newly authored concepts have been added and mapped, and three new codes for special purposes have been added to the terminology browser in accordance with World Health Organization guidelines. This release also reflects maintenance activity for concepts related to the Global Medical Device Nomenclature Agency map.
