<description
value="HL7® Austria FHIR® Core Extension for the municipality code (Gemeindecode) part of the Austrian address. The municipality code is related to the [municipality key (Gemeindekennziffer)](StructureDefinition-at-core-ext-address-municipalityKey.html). While these two are generally identical, there is one notable exception: in Vienna, the municipality key (Gemeindekennziffer) is consistently 90001, whereas the municipality code (Gemeindecode) varies by district. The current list of values is provided by [Statistik Austria](https://www.statistik.at/verzeichnis/reglisten/gemliste_knz.pdf)."/>
