Extension Exposure risk of adverse reaction (allergy or intolerance) to the specified substance/product - Detailed Descriptions

Detailed Descriptions for the elements in the extension.

Extension
Definition	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.
Control	0..1 This element is affected by the following invariants: ele-1
Comments	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").
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (xpath: @value\|f:\|h:div) ext-1: Must have either extensions or value[x], not both (xpath: exists(f:extension)!=exists(f:[starts-with(local-name(.), 'value')])) inv-1: If the substanceExposureRisk extension element is present, the AllergyIntolerance.code element must be omitted. (xpath: exists(f:substanceExposureRisk) and not(exists(f:code)))
Extension.id
Definition	unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Control	0..1
Type	string
Extension.extension
Definition	An Extension
Control	0..*
Type	Extension
Slicing	This element introduces a set of slices. The slicing rules are: unordered Open discriminators: url
Extension.extension(substance)
Definition	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.
Control	1..1
Type	Extension
Comments	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.
Extension.extension.id
Definition	unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Control	0..1
Type	string
Extension.extension.extension(extension)
Definition	An Extension
Control	0..0
Type	Extension
Extension.extension.url
Definition	Source of the definition for the extension code - a logical name or a URL.
Control	1..1
Type	uri
Comments	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.
Fixed Value	substance
Extension.extension.valueCodeableConcept
Definition	Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list).
Control	1..1
Terminology Binding	Codes defining the type of the substance (including pharmaceutical products). For example codes, see Substance Code
Type	CodeableConcept
Extension.extension(exposureRisk)
Definition	The presence or absence of a known exposure risk of the patient for an adverse reaction (allergy or intolerance) to the specified substance/product.
Control	1..1
Type	Extension
Comments	exposureRisk is a modifier of the substance.

Definition	Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list).
Control	1..1
Terminology Binding	The risk of an adverse reaction (allergy or intolerance) for this patient upon xposure to the substance (including pharmaceutical products). The codes SHALL be taken from AllergyIntoleranceSubstanceExposureRisk
