Snomed CT®

SNOMED CT® – the Systematised Nomenclature of Medicine – is a clinical terminology which is the common computerised language that will be used by all computer applications in the NHS to facilitate communications between healthcare professionals in clear and unambiguous terms. It has greater depth and coverage of healthcare than the versions of Clinical Terms (Read Codes) that it replaced and enables clinicians, researchers and patients to share and exchange healthcare and clinical knowledge worldwide.



The Health and Social Care Information Centre website provides up to date information on SNOMED CT®.  It includes a section containing details of available Training, Resources and Forums including a programme of webinars, brochures, online learning and case studies.

The International Health Terminology Standards Development Organisation based in Denmark is the not-for-profit association that owns and maintains SNOMED CT.

The UK Terminology Centre (UKTC) within the Health and Social Care Information Centre (HSCIC) is the National Release Centre for the UK and is responsible for the management of SNOMED CT, Read codes and other healthcare terminology products and Clinical Classifications. The UKTC maintains the NHS Dictionary of Medicines and Devices (dm+d) in partnership with the NHS Business Service Authority.
