This Code system is used in the following value sets:

Observation Category codes.

This code system http://hl7.org/fhir/observation-category defines the following codes:

CodeDisplayDefinition
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.
vital-signs Vital Signs Clinical 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.
imaging ImagingObservations generated by imaging. The scope includes observations, plain x-ray, ultrasound, CT, MRI, angiography, echocardiography, nuclear medicine.
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.
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.
survey SurveyAssessment tool/survey instrument observations (e.g. Apgar Scores, Montreal Cognitive Assessment (MoCA))
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.
therapy TherapyObservations generated by non-interventional treatment protocols (e.g. occupational, physical, radiation, nutritional and medication therapy)

Explanation of the columns that may appear on this page:

LevelA 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
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe 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
