This Code system is used in the following value sets:

1.30.1.11.220.1 Content

1.30.1.11.220.2 ObservationRelationshipType

Codes specifying how two observations are related.

This code system http://hl7.org/fhir/observation-relationshiptypes defines the following codes:

CodeDisplayDefinition
has-member Has MemberThis observation is a group observation (e.g. a battery, a panel of tests, a set of vital sign measurements) that includes the target as a member of the group.
derived-from Derived FromThe target resource (Observation or QuestionnaireResponse) is part of the information from which this observation value is derived. (e.g. calculated anion gap, Apgar score) NOTE: "derived-from" is only logical choice when referencing QuestionnaireResponse.
sequel-to Sequel ToThis observation follows the target observation (e.g. timed tests such as Glucose Tolerance Test).
replaces ReplacesThis observation replaces a previous observation (i.e. a revised value). The target observation is now obsolete.
qualified-by Qualified ByThe value of the target observation qualifies (refines) the semantics of the source observation (e.g. a lipemia measure target from a plasma measure).
interfered-by Interfered ByThe value of the target observation interferes (degrades quality, or prevents valid observation) with the semantics of the source observation (e.g. a hemolysis measure target from a plasma potassium measure which has no value).

Explanation of the columns that may appear on this page:

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance)
DisplayThe 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
