This expansion generated 26 Mar 2023

This value set contains 2 concepts

Expansion based on Allergy Intolerance Type v5.0.0 (CodeSystem)

Code	System	Display	Definition
allergy	http://hl7.org/fhir/allergy-intolerance-type	Allergy	A propensity for hypersensitive reaction(s) to a substance. These reactions are most typically type I hypersensitivity, plus other "allergy-like" reactions, including pseudoallergy.
intolerance	http://hl7.org/fhir/allergy-intolerance-type	Intolerance	A propensity for adverse reactions to a substance that is judged to be not allergic or "allergy-like". These reactions are typically (but not necessarily) non-immune. They are to some degree idiosyncratic and/or patient-specific (i.e. are not a reaction that is expected to occur with most or all patients given similar circumstances).

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
