Data Type Profile: Medication Unique Identifier

This unique identifier is generated within the Medication Service. It is either a hash derived from a specific set of data elements of the Medication resource or a direct repetition of a single data element. This identifier ensures the distinct identification of Medication resources across the ePA system.

Usages:

• Use this DataType Profile: EPA Pharmaceutical Product Medication, EPA Medication PZN Ingredient and EPA Medication

You can also check for usages in the FHIR IG Statistics
