       1px solid #8da1b4; border-radius: 5px; line-height: 60%  category code is A code that classifies the general type of observation being
         made. This is used for searching, sorting and display purposes.   
    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
       In FHIR, units may be represented twice. Once in the
    agreed human representation, and once in a coded form.
    Both is best, since it's not always possible to infer
    one from the other in code.
    When a computable unit is provided, UCUM (http://unitsofmeasure.org)
    is always preferred, but it doesn't provide notional units (such as
    &quot;tablet&quot;), etc. For these, something else is required (e.g. SNOMED
         CT)
