Living Dependency Code System Specification (2.3 - 1.0.0) JSON Representation
Living Dependency (2.3 - 1.0.0) - JSON Representation - v2+
HL7 International published a JSON representation for the Living Dependency vocabulary (2.3 - 1.0.0) for FHIR v2+.
Summary
HL7 has published the specification for a code system, "Living Dependency (2.3 - 1.0.0)", which identifies specific living conditions relevant to evaluating patient healthcare needs. This information is intended for use in discharge planning and is structured using FHIR standards.

Details
This document provides the technical specification (JSON representation) for a concept code system called "Living Dependency (2.3 - 1.0.0)". The system defines codes for specific living situations—such as 'Spouse dependent,' 'Medical Supervision Required,' and 'Small children'—which are useful in assessing patient care needs and planning discharge. The documentation notes that this concept was used in Version 2.3 and 2.3.1 messaging (in the NK1 segment) but has been superseded by a different code system in Version 2.4 of the Standard. Technically, it is presented within the FHIR framework as a `CodeSystem` resource type. It includes various structured data properties (e.g., versionIntroduced, versionDeprecated), demonstrating its role as a crucial technical reference for standardizing concept definitions and usage in healthcare information exchange. Implementing such standardized code systems enhances interoperability between different hospital or regional care systems. For Japanese healthcare IT, where seamless transition of care from acute care to home settings is critical, adopting standardized codes like this one can significantly improve the quality of continuous care provision by ensuring detailed living status information is accurately shared across various institutional boundaries.
