Notes: A coded concept that specifies the pharmaceutical or biological product or substance (e.g. peanut) to which the person has an allergy or intolerance.<br/><br/>Value Set:<b> </b><a href="https://fhir.infoway-inforoute.ca/ValueSet/pharmaceuticalbiologicproductandsubstancecode"><font color="#0000ff"><u>https://fhir.infoway-inforoute.ca/ValueSet/pharmaceuticalbiologicproductandsubstancecode</u></font></a> <br/>
Allergy or Intolerance Category Code Codeable Concept
Notes: A coded concept that specifies the classification of the pharmaceutical, biological product or substance (e.g. food, medication, environment) to which the person has the allergy or intolerance.<br/><br/>Value Set:<br/><a href="https://fhir.infoway-inforoute.ca/ValueSet/allergyintolerancecategory"><font color="#0000ff"><u>https://fhir.infoway-inforoute.ca/ValueSet/allergyintolerancecategory</u></font></a> <br/>

Patient Allergy or Intolerance Reaction Risk Code Codeable Concept
Notes: A coded concept that specifies an estimate of the potential clinical harm, or seriousness, of the reaction to the identified substance (e.g. low risk, high risk, unable to assess risk).<br/><br/>Value Set:<br/><a href="https://fhir.infoway-inforoute.ca/ValueSet/allergyintolerancecriticality"><font color="#0000ff"><u>https://fhir.infoway-inforoute.ca/ValueSet/allergyintolerancecriticality</u></font></a> <br/>
Patient Allergy or Intolerance Resolution Date Date

Patient Allergy or Intolerance Onset Date Time Date Time
Notes: The estimated or actual date and, if available, time when the allergy or intolerance was identified.<br/>
Allergy or Intolerance Substance Code Codeable Concept
Notes: A coded concept that specifies the particular substance (e.g., Ara h 2) considered to be responsible for the allergic or intolerance reaction.<br/><br/>Value Set: <br/><a href="https://fhir.infoway-inforoute.ca/ValueSet/substancecode"><font color="#0000ff"><u>https://fhir.infoway-inforoute.ca/ValueSet/substancecode</u></font></a> <br/>
Allergy or Intolerance Type Code Codeable Concept
Notes: A coded concept that specifies the underlying physiological mechanism for the reaction risk (e.g. allergy, intolerance).<br/><br/>Value Set:<br/><a href="https://fhir.infoway-inforoute.ca/ValueSet/allergyintolerancetype"><font color="#0000ff"><u>https://fhir.infoway-inforoute.ca/ValueSet/allergyintolerancetype</u></font></a> <br/>
Patient Allergy or Intolerance Verification Status Code Codeable Concept
Notes: A coded concept that specifies the confirmation status of the risk of reaction to the identified product or substance.<br/><br/>Value Set: <br/><a href="https://fhir.infoway-inforoute.ca/ValueSet/allergyintoleranceverificationstatus"><font color="#0000ff"><u>https://fhir.infoway-inforoute.ca/ValueSet/allergyintoleranceverificationstatus</u></font></a> <br/>
