SNOMED CT Licensing

To use SNOMED CT in software application, you need either an Affiliate License or an End-User Sub-license issued by the IHTSDO Affiliate who provided the software application. The requirement for a license applies wherever SNOMED CT is used. However, charges for use of SNOMED CT vary according to where and how SNOMED CT is used.

The following sections provide more information about obtaining a license and the situations in which payments are required for use in non-Member territories. Full details are provided in the Affiliate License Agreement.
