Consolidated CDA (C-CDA), published by Health Level Seven. This guide is not an authorized publication; it is the continuous build for version 5.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build.

Logical Model: Substance or Device Allergy - Intolerance Observation

Official URL: http://hl7.org/cda/us/ccda/StructureDefinition/SubstanceOrDeviceAllergyIntoleranceObservation Version: 5.0.0-ballot
Draft as of 2025-12-02 Computable Name: SubstanceOrDeviceAllergyIntoleranceObservation
Other Identifiers: urn:ietf:rfc:3986#Uniform Resource Identifier (URI)#urn:hl7ii:2.16.840.1.113883.10.20.24.3.90:2014-06-09

This template reflects a discrete observation about a patient's allergy or intolerance to a substance or device. Because it is a discrete observation, it will have a statusCode of "completed". The effectiveTime, also referred to as the 'clinically relevant time' is the time at which the observation holds for the patient. For a provider seeing a patient in the clinic today, observing a history of penicillin allergy that developed five years ago, the effectiveTime is five years ago.

The effectiveTime of the Substance or Device Allergy - Intolerance Observation is the definitive indication of whether or not the underlying allergy/intolerance is resolved. If known to be resolved, then an effectiveTime/high would be present. If the date of resolution is not known, then effectiveTime/high will be present with a nullFlavor of "UNK".
