FHIR Infrastructure Responsible Owner: Clinical Decision Support Work Group Normative (from v4.0.0) Use Context Standards Status : Any This is a code system defined by the FHIR project. Summary Defining URL: http://hl7.org/fhir/constraint-severity Version: 4.0.1 Name: ConstraintSeverity Title: ConstraintSeverity Definition: Informative SHALL applications comply with this constraint?

This code system http://hl7.org/fhir/constraint-severity defines the following codes: Code Display Definition error Error If the constraint is violated, the resource is not conformant. warning Raw Turtle Warning If the constraint is violated, the resource is conformant, but it is not necessarily following best practice.   See the full registry of code systems (+ also see Turtle/RDF Format Specification defined as part of FHIR. )

Explanation of the columns that may appear on this page: Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System Definition for further information. Source The source of the definition of the code (when the value set draws in codes defined elsewhere) Code The code (used as the code in the resource instance). If the code is in italics, this indicates SystemActionRequiredBehavior

Usage note: every effort has been made to ensure that the code is examples are correct and useful, but they are not selectable ('Abstract') Display The display (used in the display element of a Coding ). If there is no display, implementers should not simply display the code, but map the concept into their application Definition An explanation of the meaning normative part of the concept Comments Additional notes about how to use the code specification.
