## Resource Profile: AT APS AllergyIntolerance

Official URL: https://fhir.hl7.at/elga/aps/r4/StructureDefinition/at-aps-allergyintolerance | Version: 1.1.0
Active as of 2026-02-17 | Computable Name: AtApsAllergyIntolerance

Das AT APS-Profil für die AllergyIntolerance-Ressource berücksichtigt zum einen die österreichischen Vorgaben (z.B. Patient und zu verwendende Value-Sets) und stellt andererseits die Konformität gegenüber dem IPS-Profil sicher, indem die so genannte `imposeProfile`-Erweiterung verwendet wird.

Usages:

- Use this Profile: AT APS Bundle
- Refer to this Profile: AT APS ClinicalImpression and AT APS Composition
- Examples for this Profile: AllergyIntolerance/at-aps-example-allergyintolerance-01
- CapabilityStatements using this Profile: AT APS CapabilityStatement (Server)
