## Data Type Profile: BeObservationCodeableConcept

Official URL: https://www.ehealth.fgov.be/standards/fhir/core-clinical/StructureDefinition/be-observationcodeableconcept | Version: 1.0.1
Active as of 2025-10-16 | Maturity Level: 1 | Computable Name: BeObservationCodeableConcept

This is a supporting profile, only to give guidelines how to express a few of the typical coding systems. In general, it shall be noted SNOMED-CT is the preferred national terminology. Other coding systems remain allowed or MAY be preferred in specific flows (e.g. the use of LOINC codes to express a laboratory test.)
