| Description | This subset contains concepts that represent a health condition, sign, symptom, event, situation with explicit context or procedure for which a medication is or was prescribed to manage, improve, treat or prevent. This is a broad data exchange subset that is intended to support semantic interoperability and conformance testing. It is recommended that jurisdictions define and implement more specific clinically curated subsets that contain a portion of these concepts for data capture at the point of care for their specific use case. This subset was defined using the intensional definition of ^ 45941000087104 |Diagnoses, results of a clinical observation, assessment of judgment, normal and abnormal clinical states reference set (foundation metadata concept)| or < 272379006 |Event (event)| or < 243796009 |Situation with explicit context (situation)| or ^ 45911000087100 |Activities performed in the provision of health care reference set (foundation metadata concept)| against the substrate SNOMED CT Canadian Edition. This resource is an informative value set; a normative subset containing the expanded values can be found on Canada Health Infoway's [Terminology Server](https://infocentral.infoway-inforoute.ca/en/tools/standards-tools/terminology-server). |
