The statement of scope for the International Release is that it includes content necessary for international conformance and interoperability.

Content that is within the scope of the International Release is restricted to the International Release and may not be modified or replaced by an extension, unless explicitly permitted by SNOMED International.

SNOMED CT has an international and multilingual scope and can be localized to represent meanings and terms unique to particular organizations or localities. There are three dimensions to the scope of SNOMED CT:

International release criteria include affirmative answers to the following:

  • Does it need to be understandable in electronic health applications in more than one national healthcare system?
  • Can it be used in electronic health applications beyond a patient's national healthcare system, i.e. if a patient were to travel or relocate to a different country?
  • Is it useful in more than one national healthcare system?

A National Extension includes content outside of the scope of the International Release, but necessary for national conformance and interoperability. Each member-state determines the application and interpretation of this scope and whether or not concepts should be added to their extension.

National Extension criteria include affirmative answers to the following:

  • Is the concept outside of the scope of the International Release, but necessary for national conformance and interoperability?
  • Is it useful throughout the national healthcare system?
  • Does it need to be understandable throughout the national healthcare system?
  • Does it need to be shared in a reproducible manner within the national healthcare system?
  • If so, then the concept may be eligible for the National Extension.

SNOMED CT is not intended to cover all medical knowledge. Content that is strictly non-human is out of the scope of SNOMED CT

Examples of non-human content,

    • Egg-related coelomitis (disorder)
    • Dehorning (procedure)
    • Bone structure of wing (body structure)

Neither does SNOMED CT attempt to capture probabilistic or uncertain knowledge.
