Properties

CodeURLDescriptionType
SpecializesThe child code is a more narrow version of the concept represented by the parent code. I.e. Every child concept is also a valid parent concept. Used to allow determination of subsumption. Must be transitive, irreflexive, antisymmetric.Coding
GeneralizesInverse of Specializes. Only included as a derived relationship.Coding
internalIdhttp://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-idThe internal identifier for the concept in the HL7 Access database repository.code
statushttp://hl7.org/fhir/concept-properties#statusDesignation of a concept's state. Normally is not populated unless the state is retired.code

This code system http://terminology.hl7.org/CodeSystem/v3-ObservationCategory defines the following codes:

CodeDisplayDefinitioninternalIdstatus
exam ExamObservations 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.23740active
imaging ImagingObservations generated by imaging. The scope includes observations, plain x-ray, ultrasound, CT, MRI, angiography, echocardiography, nuclear medicine.23736active
laboratory LaboratoryThe 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, microbiology, and/or virology. These observations are based on analysis of specimens obtained from the patient and submitted to the laboratory.23737active
procedure ProcedureObservations generated by other procedures. This category includes observations resulting from interventional and non-interventional procedures excluding lab 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, such as where a gastroenterologist reports the size of a polyp observed during a colonoscopy.23738active
social-history Social HistoryThe Social History Observations define the patient's occupational, personal (e.g. lifestyle), social, and environmental history and health risk factors, as well as administrative data such as marital status, race, ethnicity and religious affiliation.23734active
survey SurveyAssessment tool/survey instrument observations (e.g. Apgar Scores, Montreal Cognitive Assessment (MoCA))23739active
therapy TherapyObservations generated by non-interventional treatment protocols (e.g. occupational, physical, radiation, nutritional and medication therapy)23741active
vital-signs Vital SignsClinical observations measure the body's basic functions such as such as blood pressure, heart rate, respiratory rate, height, weight, body mass index, head circumference, pulse oximetry, temperature, and body surface area.23735active
