## Data Type Profile: HCPD Local Identifier (HCPD-LI)

Official URL: http://digitalhealth.gov.au/fhir/hcpd/StructureDefinition/hcpd-local-identifier | Version: 26.0.0

This profile of Identifier defines a HCPD Local Identifier (HCPD-LI) used for system reference and internal business logic.

#### HCD Local Identifier

Beyond the identifiers already defined in AU Core, the following HCPD resource profiles: Location, PractitionerRole, HealthcareService & Endpoint explicitly support a unique Health Connect Provider Directory attributed slice. The value of this identifier is uniquely assigned at creation, therefore this prevents duplications of values regardless of resource type.

Publishing guidance:

- The HCPD Local Identifier (HCPD-LI) is the canonical identifier for resources internally within the Health Connect Provider Directory system and SHALL be supplied when known. Publishing systems SHALL NOT manipulate the HCPD-LI value themselves — the HCPD service SHALL generate and manage this identifier.

Usages:

- Use this DataType Profile: HCPD Endpoint, HCPD HealthcareService, HCPD Location and HCPD PractitionerRole

You can also check for usages in the FHIR IG Statistics
