Extension: substanceExposureRisk

URL for this extension:

http://hl7.org/fhir/StructureDefinition/allergyintolerance-substanceExposureRisk

Status: draft. Extension maintained by: Health Level Seven, Inc. - FHIR WG

A complex extension allowing structured capture of the exposure risk of the patient for an adverse reaction (allergy or intolerance) to the specified substance/product.

Comment:

This extension is available and is intended to be used as a more completely structured and flexible alternative to the 'code' element for representing positive and negative allergy and intolerance statements. If this extension element is present, the AllergyIntolerance.code element SHALL be omitted (see invariant "code or substanceExposureRisk").

Context of Use: Use on Element ID AllergyIntolerance
