Observation Category Codes extended for use in an Australian context. Includes HL7 international codes plus Australian additions to create a complete set.

References

This value set is not used here; it may be used elsewhere (e.g. specifications and/or implementations that use this content)

Changes since version 5.0.0:

- New Content

### Logical Definition (CLD)

Profile: `https://healthterminologies.gov.au/fhir/StructureDefinition/composed-value-set-4`

This value set includes codes based on the following rules:

- Include all codes defined in `http://terminology.hl7.org.au/CodeSystem/observation-category`
- Import all the codes that are contained in Observation Category Codes

### Expansion

Expansion performed internally based on:

- codesystem Observation Category Codes AU v6.0.0-draft (CodeSystem)
- codesystem Observation Category Codes v1.0.1 (CodeSystem)
- valueset Observation Category Codes v4.0.1 (ValueSet)

This value set contains 10 concepts

Code | System | Display (en-AU) | Definition
program | http://terminology.hl7.org.au/CodeSystem/observation-category |  | Observations that describe an individual’s participation in one or more health programs such as treatment or prevention or public health (e.g. disease screening or substance use therapy).
social-history | http://terminology.hl7.org/CodeSystem/observation-category |  | Social History Observations define the patient's occupational, personal (e.g., lifestyle), social, familial, and environmental history and health risk factors that may impact the patient's health.
vital-signs | http://terminology.hl7.org/CodeSystem/observation-category |  | Clinical observations measure the body's basic functions such as blood pressure, heart rate, respiratory rate, height, weight, body mass index, head circumference, pulse oximetry, temperature, and body surface area.
imaging | http://terminology.hl7.org/CodeSystem/observation-category |  | Observations generated by imaging. The scope includes observations regarding plain x-ray, ultrasound, CT, MRI, angiography, echocardiography, and nuclear medicine.
laboratory | http://terminology.hl7.org/CodeSystem/observation-category |  | The results of observations generated by laboratories. Laboratory results are typically generated by laboratories providing analytic services in areas such as chemistry, hematology, serology, histology, cytology, anatomic pathology (including digital pathology), microbiology, and/or virology. These observations are based on analysis of specimens obtained from the patient and submitted to the laboratory.
procedure | http://terminology.hl7.org/CodeSystem/observation-category |  | Observations generated by other procedures. This category includes observations resulting from interventional and non-interventional procedures excluding laboratory and imaging (e.g., cardiology catheterization, endoscopy, electrodiagnostics, etc.). Procedure results are typically generated by a clinician to provide more granular information about component observations made during a procedure. An example would be when a gastroenterologist reports the size of a polyp observed during a colonoscopy.
survey | http://terminology.hl7.org/CodeSystem/observation-category |  | Assessment tool/survey instrument observations (e.g., Apgar Scores, Montreal Cognitive Assessment (MoCA)).
exam | http://terminology.hl7.org/CodeSystem/observation-category |  | Observations generated by physical exam findings including direct observations made by a clinician and use of simple instruments and the result of simple maneuvers performed directly on the patient's body.
therapy | http://terminology.hl7.org/CodeSystem/observation-category |  | Observations generated by non-interventional treatment protocols (e.g. occupational, physical, radiation, nutritional and medication therapy)
activity | http://terminology.hl7.org/CodeSystem/observation-category |  | Observations that measure or record any bodily activity that enhances or maintains physical fitness and overall health and wellness. Not under direct supervision of practitioner such as a physical therapist. (e.g., laps swum, steps, sleep data)

Explanation of the columns that may appear on this page:

Level | A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System | The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code | The code (used as the code in the resource instance)
Display | The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition | An explanation of the meaning of the concept
Comments | Additional notes about how to use the code
