    Observations are often coded in multiple code systems.
      - LOINC provides codes of varying granularity (though not usefully more specific in this particular case) and more generic LOINCs  can be mapped to more specific codes as shown here
      - snomed provides a clinically relevant code that is usually less granular than LOINC
      - the source system provides its own code, which may be less or more granular than LOINC
