The ‘substanceExposureRisk’ extension is a structured and more flexible alternative to AllergyIntolerance.code for making positive or negative allergy or intolerance statements. This extension provides the capability to make “no known allergy” (or “no risk of adverse reaction”) statements regarding any coded substance/product (including cases when a pre-coordinated “no allergy to x” concept for that substance/product does not exist). If the ‘substanceExposureRisk’ extension is present, the AllergyIntolerance.code element SHALL be omitted.

    Summary

    Complex Extension: The 'substanceExposureRisk' extension is a structured and more flexible alternative to AllergyIntolerance.code for making positive or negative allergy or intolerance statements. This extension provides the capability to make "no known allergy" (or "no risk of adverse reaction") statements regarding any coded substance/product (including cases when a pre-coordinated "no allergy to x" concept for that substance/product does not exist). If the 'substanceExposureRisk' extension is present, the AllergyIntolerance.code element SHALL be omitted.

    • substance: CodeableConcept: Code for a substance or pharmaceutical product that is considered to be responsible for the adverse reaction risk or is known not to have an associated risk of an adverse reaction upon exposure.
    • exposureRisk: CodeableConcept: The presence or absence of a known exposure risk of the patient for an adverse reaction (allergy or intolerance) to the specified substance/product.
