XQT lays the foundation for making clinical information available early, securely, and with quality assurance. ordomediq (Gesellschaft für medizinisches Honorarmanagement mbH) expands this foundation in the APPLY layer with GOÄ application logic that transforms medical documentation—both via FHIR-based data paths and from PDFs converted into FHIR data—into traceable and interoperable private billing processes. In this way, data sovereignty becomes a concrete clinical use case with economic impact, operational relevance, and clear structural sustainability.
