Data Type Profile: Identifier

See also Enterprise Integration Patterns - Correlation Identifier and Rule 3: Reference Other Aggregates by Identity (Implementing Domain Driven Design)

This relates directly to HL7 v2 Data Types

EI - Entity Identifier

The EI.2 - Namespace Id (FHIR Identifier.assigner.value) should be an ODS code. E.g. ORC segment (extract)

ORC|RE|ABC123^ROA|XYZ789^699X0

where ROA is the ODS code for Manchester University NHS Foundation Trust and 699XO is the ODS code from NW Region GLH

CX - Extended Composite ID with Check Digit

The 'CX.6 - Assigning Facility' (FHIR Identifier.assigner.value) should be an ODS code. E.g. ORC segment (extract)

PID|1||EPI1234^^^MR^ROA||Doe^John^Michael^Mr.||19800101|123 Main St^Anytown^CA^12345||555-1234||S||ABC123|987654321|M

where ROA is the ODS code for Manchester University NHS Foundation Trust
