extension namespace identifier
extension namespace identifier
A seven digit number allocated by SNOMED International to an organization that is permitted to maintain a SNOMED CT Extension.
Notes
The namespace identifier enables an authorized organization to generate a unique SNOMED CT identifier (SCTID) for each of their SNOMED CT components. It forms part of the SCTID assigned to every component created by that organization.
Short format SCTIDs, which are used for components that originate from SNOMED International, do not include a namespace identifier. For these SCTIDs the partition identifier provides sufficient information about the origin of the component.
