  sdohhttp://hl7.org/fhir/us/core/CodeSystem/us-core-tagsSDOHSocial Determinants of Health Category
  clinical-testhttp://hl7.org/fhir/us/core/CodeSystem/us-core-observation-categoryClinical TestIncludes non-imaging and non-laboratory tests performed on a patient that results in structured or unstructured (narrative) findings specific to the patient, such as electrocardiogram (ECG), visual acuity exam, macular exam, or graded exercise testing (GXT), to facilitate the diagnosis and management of conditions.
  social-historyhttp://terminology.hl7.org/CodeSystem/observation-categorySocial HistorySocial 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-signshttp://terminology.hl7.org/CodeSystem/observation-categoryVital SignsClinical 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.
  imaginghttp://terminology.hl7.org/CodeSystem/observation-categoryImagingObservations generated by imaging. The scope includes observations regarding plain x-ray, ultrasound, CT, MRI, angiography, echocardiography, and nuclear medicine.
  laboratoryhttp://terminology.hl7.org/CodeSystem/observation-categoryLaboratoryThe 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.
  procedurehttp://terminology.hl7.org/CodeSystem/observation-categoryProcedureObservations 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.
  surveyhttp://terminology.hl7.org/CodeSystem/observation-categorySurveyAssessment tool/survey instrument observations (e.g., Apgar Scores, Montreal Cognitive Assessment (MoCA)).
  examhttp://terminology.hl7.org/CodeSystem/observation-categoryExamObservations 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.
  therapyhttp://terminology.hl7.org/CodeSystem/observation-categoryTherapyObservations generated by non-interventional treatment protocols (e.g. occupational, physical, radiation, nutritional and medication therapy)
  activityhttp://terminology.hl7.org/CodeSystem/observation-categoryActivityObservations 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
