## Extension: Section Coding

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

This extension allows for the assignment of a specific code to a section within a Composition resource. The code provides a standardized way to categorize or identify the content of the section, enabling better organization, searchability, and interoperability of clinical documents or other structured artifacts.

The SectionCoding extension is used to indicate a specific code to a section within a Composition resource. The code provides a standardized way to categorize or identify the content of the section, enabling better organization, searchability, and interoperability of clinical documents or other structured artifacts.

Context of Use

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

- Element ID: `Element`

### Guidance

This extension allows assigning a specific code to a section within a Composition resource.

#### Overview

Section coding provides a standardized way to categorize or identify the content of sections, enabling better organization, searchability, and interoperability. It is particularly useful for sections that need coded values (e.g., care setting, care stage).

#### Context

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

#### Value Type

The value is a `CodeableConcept`:

    * value[x] only CodeableConcept
    * valueCodeableConcept 1..1

#### Use Cases

- Care Setting: Classify whether ambulatory, inpatient, or mixed
- Care Stage: Classify as prevention, diagnosis, therapy, etc.
- Care Level: Classify as primary care, specialist care, etc.

#### Example Usage

    // In a care setting section:
    * section[careSetting]
      * section[careSetting]
        * extension[value].valueCodeableConcept from vs-encounter-type (extensible)
      * section[careStage]
        * extension[value].valueCodeableConcept from vs-care-stage (extensible)
      * section[careLevel]
        * extension[value].valueCodeableConcept from vs-care-level (extensible)
