AllergyIntolerance Substance Exposure Risk
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.
Exposure risk of adverse reaction (allergy or intolerance) to the specified substance/product
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.
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Must have either extensions or value[x], not both
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
Additional content defined by implementations
May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
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.
It is strongly recommended that this element be populated using a terminology, where possible. For example, some terminologies used include RxNorm, SNOMED CT, DM+D, NDFRT, UNII, and ATC. Plain text should only be used if there is no appropriate terminology available. Additional details can be specified in the text.

Source of the definition for the extension code - a logical name or a URL.
The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R5/extensibility.html) for a list).
Codes defining the type of the substance (including pharmaceutical products).
known-reaction-risk | no-known-reaction-risk
The presence or absence of a known exposure risk of the patient for an adverse reaction (allergy or intolerance) to the specified substance/product.
exposureRisk is a modifier of the substance.
The risk of an adverse reaction (allergy or intolerance) for this patient upon exposure to the substance (including pharmaceutical products).
