Concepts

This case-sensitive code system http://hl7.org/fhir/allergy-intolerance-type defines the following codes:

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