You can use the service as many times as you wish. If you wish to access more detailed SNOMED CT data and structures, please see the information under Join Us.

Although many SNOMED CT concepts have been translated into several languages the web-based lookup service currently only shows the English language terms. Additionally the current release of the lookup service does not show which of the synonyms is the preferred term for the selected concept. Preferred term information for each dialect is provided in a language reference set which is part of the SNOMED CT release.

The Lookup Service is in its first phase of development and we would welcome your feedback; if you wish to assist us in developing the service to meet your needs please provide feedback via email to
