| Field | Card. | Type | Description | 
|---|---|---|---|
| resolutionAge | 0..1 | Extension | The estimated patient age at which the allergy or intolerance resolved. Should be specified only if the status is resolved. | 
| reasonRefuted | 0..1 | Extension | A code capturing the explanation of why the allergy or intolerance has been refuted. Should be specified only if the status is refuted. Binding: The value set to instantiate this attribute should be drawn from a terminologically robust code system for reasons of refuting an allergy or intolerance. This value set is provided as a suggestive example. (example)  | 
| clinicalStatus | 0..1 | String | The clinical status of the allergy or intolerance. Binding: http://hl7.org/fhir/ValueSet/allergy-clinical-status (required)  | 
| verificationStatus | 1..1 | String | Assertion about certainty associated with the propensity, or potential risk, of a reaction to the identified substance (including pharmaceutical product). Binding: http://hl7.org/fhir/ValueSet/allergy-verification-status (required)  | 
| type | 0..1 | String | Identification of the underlying physiological mechanism for the reaction risk. Binding: Identification of the underlying physiological mechanism for a Reaction Risk. (required)  | 
| category | 0..* | List<String> | Category of the identified substance. Binding: Category of an identified substance. (required)  | 
| criticality | 0..1 | String | Estimate of the potential clinical harm, or seriousness, of the reaction to the identified substance. Binding: Estimate of the potential clinical harm, or seriousness, of a reaction to an identified substance. (required)  | 
| code | 1..1 | Concept | Code for an allergy or intolerance statement (either a positive or a negated/excluded statement).  This may be a code for a substance or pharmaceutical product that is considered to be responsible for the adverse reaction risk (e.g., "Latex"), an allergy or intolerance condition (e.g., "Latex allergy"), or a negated/excluded code for a specific substance or class (e.g., "No latex allergy") or a general or categorical negated statement (e.g.,  "No known allergy", "No known drug allergies"). Binding: A substance or other type of agent (e.g., sunshine) that may be associated with an intolerance reaction event or a propensity to such an event. (preferred)  | 
| patient | 1..1 | Patient | The patient who has the allergy or intolerance. | 
| assertedDate | 0..1 | DateTime | The date on which the existance of the AllergyIntolerance was first asserted or acknowledged. | 
| recorder | 0..1 | Practitioner | Patient | Individual who recorded the record and takes responsibility for its content. | 
| asserter | 0..1 | Patient | RelatedPerson | Practitioner | The source of the information about the allergy that is recorded. | 
| reaction | 0..* | List<reaction> | Details about each adverse reaction event linked to exposure to the identified substance. | 
| reaction-duration | 0..1 | Extension | The amount of time that the Adverse Reaction persisted. |
