The NHS Digital SNOMED CT Browser

The NHS Digital SNOMED CT Browser provides ways to browser and search the SNOMED CT UK Edition. The SNOMED CT UK Edition consists of the International Edition plus the UK-specific content provided within the UK Clinical Extension, the UK Drug Extension, and the UK Pathology Extension including maps to ICD-10 and OPCS-4. This is for use in the UK only. Please see the SNOMED CT Release Schedule for more information

Note that the NHS Digital SNOMED CT Browser is updated in line with the SNOMED CT UK Edition release schedule, and will therefore not always align with content in the latest SNOMED CT International Edition release.

The Browser is provided by NHS Digital to anyone for reference purposes. The interface and REST APIs are not to be used as part of production systems. There are other tools developed by IHTSDO for Members for the use in health care settings.
