Extension: Section Keyword

Official URL: http://fhir.awmf.org/awmf.ig/StructureDefinition/ext-section-keyword Version: 0.2.0
Draft as of 2026-01-29 Computable Name: SectionKeyword

This extension allows for the indication of keywords associated with the section

The SectionKeyword extension is used to capture keywords associated with the section.

Context of Use

    This extension may be used on the following element(s)

Guidance

This extension allows adding keywords to sections for improved searchability and categorization.

Overview

Keywords help identify the clinical concepts covered in a section. They can be coded using standard terminologies or provided as free text.

Context

This extension can be applied to any Element (typically Composition sections).

Value Type

The value is a CodeableConcept with support for multiple coding systems:

* value[x] only CodeableConcept
* valueCodeableConcept 1..1
  * coding contains
    icd10-gm 0..1 MS and
    sct 0..1 MS and
    loinc 0..1 MS and
    ops 0..1 MS and
    atc 0..1 MS and
    atcde 0..1 MS

Supported Code Systems

Slice Code System Description
icd10-gm ICD-10-GM German modification of ICD-10
sct SNOMED CT Systematized Nomenclature of Medicine
loinc LOINC Laboratory tests, clinical observations
ops OPS German procedure classification
atc ATC WHO Anatomical Therapeutic Chemical
atcde ATC-DE German ATC extension

Example Usage

// In a population section:
* section[population]
  * section[language]
    * extension[keyword][+].valueCodeableConcept
      * coding[sct] = $sct#73211009 "Diabetes mellitus"
    * extension[keyword][+].valueCodeableConcept
      * coding[icd10-gm] = $icd10-gm#E11 "Type 2 diabetes mellitus"
