Code Display Definition
missing Missing The search parameter returns resources that have a value or not.
exact Exact The search parameter returns resources that have a value that exactly matches the supplied parameter (the whole string, including casing and accents).
contains Contains The search parameter returns resources that include the supplied parameter value anywhere within the field being searched.
not Not The search parameter returns resources that do not contain a match.
text Text The search parameter is processed as a string that searches text associated with the code/value - either CodeableConcept.text, Coding.display, or Identifier.type.text.
in In The 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.
not-in Not In The 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.
below Below The search parameter tests whether the value in a resource is subsumed by the specified value (is-a, or hierarchical relationships).
above Above The search parameter tests whether the value in a resource subsumes the specified value (is-a, or hierarchical relationships).
type Type The search parameter only applies to the Resource Type specified as a modifier (e.g. the modifier is not actually :type, but :Patient etc.).
identifier Identifier The search parameter applies to the identifier on the resource, not the reference.
ofType Of Type The 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.

Explanation of the columns that may appear on this page:

Lvl A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System 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 that the code is 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 of the concept
Comments Additional notes about how to use the code
