      <comment value="Allergic (typically immune-mediated) reactions have been traditionally regarded
       as an indicator for potential escalation to significant future risk. Contemporary
       knowledge suggests that some reactions previously thought to be immune-mediated
       are, in fact, non-immune, but in some cases can still pose a life threatening risk.
       It is acknowledged that many clinicians might not be in a position to distinguish
       the mechanism of a particular reaction. Often the term &quot;allergy&quot; is used
       rather generically and may overlap with the use of &quot;intolerance&quot; - in
       practice the boundaries between these two concepts might not be well-defined or
       understood. This data element is included nevertheless, because many legacy systems
       have captured this attribute. Immunologic testing may provide supporting evidence
       for the basis of the reaction and the causative substance, but no tests are 100%
       sensitive or specific for sensitivity to a particular substance. If, as is commonly
       the case, it is unclear whether the reaction is due to an allergy or an intolerance,

       statement).  This may be a code for a substance or pharmaceutical product that
       is considered to be responsible for the adverse reaction risk (e.g., &quot;Latex&quot;),
       an allergy or intolerance condition (e.g., &quot;Latex allergy&quot;), or a negated/excluded

       may be different from the substance identified as the cause of the risk, but it
       must be consistent with it. For instance, it may be a more specific substance (e.g.
       a brand medication) or a composite product that includes the identified substance.
       It must be clinically safe to only process the 'code' and ignore the 'reaction.substance'.
        If a receiving system is unable to confirm that AllergyIntolerance.reaction.substance
       falls within the semantic scope of AllergyIntolerance.code, then the receiving
       system should ignore AllergyIntolerance.reaction.substance."/> 
      <comment value="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, ICD-9, IDC-10, UNII, and ATC. Plain text should only be used if there
       is no appropriate terminology available. Additional details can be specified in
       the text.

When a substance or product code is specified for the 'code' element, the &quot;default&quot;
       semantic context is that this is a positive statement of an allergy or intolerance
       (depending on the value of the 'type' element, if present) condition to the specified
       substance/product.  In the corresponding SNOMED CT allergy model, the specified
       substance/product is the target (destination) of the &quot;Causative agent&quot;
       relationship.

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

      <comment value="Allergic (typically immune-mediated) reactions have been traditionally regarded
       as an indicator for potential escalation to significant future risk. Contemporary
       knowledge suggests that some reactions previously thought to be immune-mediated
       are, in fact, non-immune, but in some cases can still pose a life threatening risk.
       It is acknowledged that many clinicians might not be in a position to distinguish
       the mechanism of a particular reaction. Often the term &quot;allergy&quot; is used
       rather generically and may overlap with the use of &quot;intolerance&quot; - in
       practice the boundaries between these two concepts might not be well-defined or
       understood. This data element is included nevertheless, because many legacy systems
       have captured this attribute. Immunologic testing may provide supporting evidence
       for the basis of the reaction and the causative substance, but no tests are 100%
       sensitive or specific for sensitivity to a particular substance. If, as is commonly
       the case, it is unclear whether the reaction is due to an allergy or an intolerance,
       then the type element should be omitted from the resource."/>

       has identified a propensity for a more serious or potentially life-threatening
       reaction, such as anaphylaxis, and implies an absolute contraindication to deliberate
       or voluntary exposure to the substance. If this element is missing, the criticality
       is unknown (though it may be known elsewhere).  Systems that capture a severity
       at the condition level are actually representing the concept of criticality whereas
       the severity documented at the reaction level is representing the true reaction
       severity.  Existing systems that are capturing both condition criticality and reaction
       severity may use the term &quot;severity&quot; to represent both.  Criticality
       is the worst it could be in the future (i.e. situation-agnostic) whereas severity
       is situation-dependent."/>

       a brand medication) or a composite product that includes the identified substance.
       It must be clinically safe to only process the 'code' and ignore the 'reaction.substance'.
        If a receiving system is unable to confirm that AllergyIntolerance.reaction.substance

      <comment value="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, ICD-9, IDC-10, UNII, and ATC. Plain text should only be used if there
       is no appropriate terminology available. Additional details can be specified in
       the text.

When a substance or product code is specified for the 'code' element, the &quot;default&quot;
       semantic context is that this is a positive statement of an allergy or intolerance
       (depending on the value of the 'type' element, if present) condition to the specified
       substance/product.  In the corresponding SNOMED CT allergy model, the specified
       substance/product is the target (destination) of the &quot;Causative agent&quot;
       relationship.

The 'substanceExposureRisk' extension is available as a structured and more flexible
       alternative to the 'code' element for making positive or negative allergy or intolerance
       statements.  This extension provides the capability to make &quot;no known allergy&quot;
       (or &quot;no risk of adverse reaction&quot;) statements regarding any coded substance/product
       (including cases when a pre-coordinated &quot;no allergy to x&quot; concept for
       that substance/product does not exist).  If the 'substanceExposureRisk' extension
