The issue / feature

Change description

The PBS / RPBS live feed includes medication form and strength by referencing an extension with an Agency canonical URL http://ns.electronichealth.net.au/fhir/StructureDefinition/medication-form-and-strength however this extension does not exist.

A similar Mobile Gateway extension http://ns.electronichealth.net.au/fhir/v1.2.0/StructureDefinition/medication-form-and-strength is published but cannot be used as it is an earlier forwards incompatible version of FHIR.

If the FHIR payload needs to carry this information the Agency should create and publish this extension in the Medicare Records FHIR implementation guide.

                    "url": "http://ns.electronichealth.net.au/fhir/StructureDefinition/medication-form-and-strength",
                    "valueString": "BENZYLPENICILLIN 3G INJECTION, 1 VIAL"
                }
            ],
