Austrian Address Code Extension: FHIR Specification for Municipality Information Released

Details

This document is part of the HL7® Austria FHIR Core Implementation Guide and details the specifications for an extension called 'Address Municipality Code.' This extension is specifically designed to handle the municipality code component within Austrian address information. Technically, the extension applies to the `Address` element and is defined as a structure with a specific URL (`http://hl7.at/fhir/...`). The data type is string, built upon FHIR v4.0.1. By providing this specification, healthcare institutions and systems within Austria can exchange regional codes for addresses in a standardized format. This significantly improves interoperability, particularly in fields where geographical context is critical, such as drug management or public health data analysis. This guideline offers concrete technical instructions for enhancing the quality and comprehensiveness of medical information at the national level through structured FHIR data representation.
