Guidance

SNOMED CT Swiss Extension

Within the EPR, SNOMED CT is used for the metadata and in the exchange formats, see here.
SNOMED CT is designed so that the International Edition can be complemented by creating extensions to meet national or local requirements. Since December 2021, the Swiss Extension is available and includes translations in German, French and Italian.

The guidance for Switzerland is that the version element should only be added when using codes from the Swiss extension.
The following section illustrates the usage in value sets exemplarily. For the usage in instances , see the corresponding guidance in CH Core.
