1.25.2.1.220.1 Content Logical Definition

This value set has an inline code system http://hl7.org/fhir/observation-relationshiptypes, which defines the following codes:

Code	Display	Definition	v3 Map (ActRrelationshipType)
has-member	Has Member	This 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.	=MBR
derived-from	Derived From	The 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.	=DRIV
sequel-to	Sequel To	This observation follows the target observation (e.g. timed tests such as Glucose Tolerance Test).	=SEQL
replaces	Replaces	This observation replaces a previous observation (i.e. a revised value). The target observation is now obsolete.	=RPLC
qualified-by	Qualified By	The value of the target observation qualifies (refines) the semantics of the source observation (e.g. a lipemia measure target from a plasma measure).	=QUALF
interfered-by	Interfered By	The 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).	=INTF

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. In this scheme, some codes are under other codes, and imply that the code they are under also applies

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)

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
