## Extension: GFEServiceLinkingInfo 

| | | |
| :--- | :--- | :--- |
| *Official URL*:http://hl7.org/fhir/us/davinci-pct/StructureDefinition/gfeServiceLinkingInfo | *Version*:2.0.1 | |
| * Standards status: *[Trial-use](http://hl7.org/fhir/R4/versions.html#std-process) | [Maturity Level](http://hl7.org/fhir/versions.html#maturity): 2 | *Computable Name*:GFEServiceLinkingInfo |
| *Other Identifiers:*OID:2.16.840.1.113883.4.642.40.4.42.29 | | |

This extension is used to provide the GFE Service Linking Information. This allows implementers to have the same identifier on multiple GFEs that are part of one period of care's services. This would be needed for some of the workflow options that businesses may decide to use.
