All codes in this table are from the system

INInstrumentAssigned by the instrument used to process the sample and generate the result.
LMLIMS (Standalone or EHR)Code is assigned by the system used to manage laboratory results, either stand-alone or as part of the EHR.
HLHL7 feed or other interfaceCode is assigned from an external HL7 feed or other interface (e.g., by a Health Information Exchange).
DWData warehouseLOINC codes are generated during the extract-transform-load (ETL) procedures used to populate a standalone data warehouse or reporting database.
PCPCORnet ETLLOINC codes are assigned as part of the ETL process used to populate the PCORnet CDM.
DMOther CDMCodes are assigned through the ETL used to populate a CDM that is upstream from the PCORnet ETL.

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
Source 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
