## Extension: EDI Address

Official URL: http://hl7.org.nz/fhir/StructureDefinition/edi-address | Version: 0.1.0
Active as of 2020-07-20 | Computable Name: Edi_address
Copyright/Legal: HL7 New Zealand© 2020+; Licensed Under Creative Commons No Rights Reserved.

Represents an Electronic Data Interchange (EDI) address. It is intended as an extension on ContactPoint.system, with the system value being 'other'. The value of the extension is the EDI supplier, the actual EDI address is the value element. Note that a new extension 'messaging address' is preferred.

Context of Use

This extension may be used on the following element(s)

- Element ID: `ContactPoint.system`

This extension has been deprecated, and the Messaging Address extension should be used instead. The status will be changed to 'retired' in the next version of this guide.

This extension allows an EDI address to be added to the ContactPoint.system element.

As the FHIR specification has a required binding for this element, it is necessary to provide a value from the defined set (eg 'other') then place the extension on that value.

The actual value of the edi address is the .value element.

In the example below, the extension (on telecom.system) indicates that this is an EDI address supplied by HealthLink. The actual value of the EDI address (on telecom.value) is 001a

Example of extension

      <telecom>
        <system value="other">
          <extension url="http://hl7.org.nz/fhir/StructureDefinition/edi-address">
            <valueString value="healthlink"/>
          </extension>
        </system>
        <value value="001a"/>
      </telecom>
