This Code system is used in the following value sets:


A supported modifier for a search parameter.

This code system http://hl7.org/fhir/search-modifier-code defines the following codes:

CodeDisplayDefinitionCopy
missing MissingThe search parameter returns resources that have a value or not.btn btn
exact ExactThe search parameter returns resources that have a value that exactly matches the supplied parameter (the whole string, including casing and accents).btn btn
contains ContainsThe search parameter returns resources that include the supplied parameter value anywhere within the field being searched.btn btn
not NotThe search parameter returns resources that do not contain a match.btn btn
text TextThe search parameter is processed as a string that searches text associated with the code/value - either CodeableConcept.text, Coding.display, Identifier.type.text, or Reference.display.btn btn
in InThe search parameter is a URI (relative or absolute) that identifies a value set, and the search parameter tests whether the coding is in the specified value set.btn btn
not-in Not InThe search parameter is a URI (relative or absolute) that identifies a value set, and the search parameter tests whether the coding is not in the specified value set.btn btn
below BelowThe search parameter tests whether the value in a resource is subsumed by the specified value (is-a, or hierarchical relationships).btn btn
above AboveThe search parameter tests whether the value in a resource subsumes the specified value (is-a, or hierarchical relationships).btn btn
type TypeThe search parameter only applies to the Resource Type specified as a modifier (e.g. the modifier is not actually :type, but :Patient etc.).btn btn
identifier IdentifierThe search parameter applies to the identifier on the resource, not the reference.btn btn
of-type Of TypeThe search parameter has the format system|code|value, where the system and code refer to an Identifier.type.coding.system and .code, and match if any of the type codes match. All 3 parts must be present.btn btn
code-text Code TextTests whether the textual display value in a resource (e.g., CodeableConcept.text, Coding.display, or Reference.display) matches the supplied parameter value.btn btn
text-advanced Text AdvancedTests whether the value in a resource matches the supplied parameter value using advanced text handling that searches text associated with the code/value - e.g., CodeableConcept.text, Coding.display, or Identifier.type.text.btn btn
iterate IterateThe search parameter indicates an inclusion directive (_include, _revinclude) that is applied to an included resource instead of the matching resource.btn btn

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. See Code System for further information.
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). If the code is in italics, this indicates that the code is not selectable ('Abstract')
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
