Concepts

This case-sensitive code system `http://terminology.hl7.org/v2plusvocab/CodeSystem/v2CS-relationshipType` defines the following codes:

Code | Display | Definition | version introduced | comment, to suppress IG-publisher warning, to be replaced with standard later | modified

COMP | Component of | Target universal service identifier is a component of source universal identifier | 2.9 | Example: one care plan activity (target) is a component of another care plan activity (source) | 2022-08-25
CONCR | Concurrently | Source and target universal service identifier should start concurrently | 2.9 | Example: two care plan activities should start concurrently | 2022-08-25
EVID | Evidence | Source universal service identifier provides evidence for target universal service identifier | 2.9 | Example: observation result provides evidence for certain care plan activity or treatment action | 2022-08-25
INTF | Interferes / interfered | Source universal service identifier interferes / interfered with fulfilment of target universal service identifier | 2.9 | Example: patient financial or physical constraints interferes / interfered with fulfilment of goal | 2022-08-25
LIMIT | Limits/limited | Source universal service identifier limits/limited the fulfillment of target universal service identifier | 2.9 | Example: patient condition limits the extend that planned treatment can be implemented | 2022-08-25
SUCCD | Succeeds | Target universal service identifier should succeed (starts after end of) source universal service identifier | 2.9 | Example: one care plan activity (target) should start after completion of another (source) | 2022-08-25
SVTGT | Service target | Target universal service identifier is the object of the service identified by the source universal service identifier | 2.9 | Example: An order requests clarification or interpretation of a previous clinical laboratory test result | 2022-08-25
