## description

This code system represents resource IDs of the source practitioner.

For reasons of implementation efficiency, the resource ID is sometimes returned as a Coding in the **meta.security** element of a resource.

The extension which represents the same information when not in a Coding is: [http://fhir.patientsknowbest.com/structuredefinition/source-person](http://fhir.patientsknowbest.com/structuredefinition/source-person) (but note that this is a more general extension which can capture a source person that is not necessarily a practitioner).
