SNOMED CT UK Edition

The SNOMED CT UK Edition is released twice per year and consists of the International Edition plus the UK-specific content provided within the UK Clinical Extension and UK Drug Extension and which is for use in the UK only. The international Edition on its own is insufficient for use in the UK.

To download the files, select ‘UK Edition of SNOMED CT’ from the list on the left hand side of the relevant area on TRUD.

A new release of the SNOMED CT UK Edition is provided a short time after each release of the International Edition to allow UK-specific content to be included. A new release of the SNOMED CT UK Edition is provided in April and October of each year.

Important Notice: The Standardisation Committee for Care Information (SCCI) has announced changes to the SNOMED CT standard with the time frames to cease the provision of the data-files in Release Format 1 (RF1). SNOMED CT will be provided in Release Format 2 (RF2) only, after 1st April 2018. Details of the standard and this change can be found here. All current users of SNOMED CT RF1 should be ready to process releases in RF2 after 1st April 2018.

SNOMED CT UK Derivative Products

There are a number of resources developed by the UK teams designed to support successful implementation of SNOMED CT which are referred to as derivative products as they are in some form derived from SNOMED CT content. These are most commonly mappings or subsets and these are available as packs on TRUD.

Maps / Mapping Table examples:

UK Clinical Edition, RF1 Cross-maps: Provides mappings from SNOMED CT to ICD-10 and OPCS-4 Classifications. More information can be found on the Cross-mapping page.

NHS Data Migration:  Provides mappings to support the migration of primary care systems from the Read Codes to SNOMED CT.

SNOMED Antecedent Versions Data Migration: Mapping from older versions of SNOMED to SNOMED CT - some areas of pathology laboratories are currently dependent on using legacy SNOMED products to SNOMED CT.

SNOMED CT Subsets

Sometimes it can be useful to have only part of the SNOMED CT vocabulary available. To facilitate this, we provide products known as ‘SNOMED CT subsets’. Subsets provide a set of components from the full Edition of SNOMED CT and are usually defined by a particular requirement, e.g. all procedures carried out in an ophthalmology clinic.

We issue a number of subsets in the UK Edition which have been defined for a specific national purpose and in some cases have been developed by a professional body for their members.

The Data Dictionary for Care provides details of all the subsets available in the UK release.

How can I request a change?

You should submit requests for new terms or concepts to SNOMED CT UK via the NHS Digital Request Submission Portal (RSP) and select SNOMED CT from the products list. You will need to register before being able to request new terms or changes and, once registered, you will be able to view existing user to see if the term has already been requested.

We support requests for new content and changes to existing content from all UK countries; however we would request that users in Scotland make their requests directly to NHS Scotland ISD Terminology Services.

You may find it useful to understand how terms are worded and added to the terminology and this may help you when making requests for new terms. This short presentation runs through some of the important editorial principles and provides a summary of the request process.

UK Drug Extension or dm+d requests for change need to be submitted via the dm+d website.
