contextCodeThis optional code is used to categorize the Diagnosis in such a manner as to accommodate LOINC codes that are required by certain implementations (especially CDA). In the FHIM, the "type" of diagnosis is conveyed by the context of the class pointing to this class. For example, an association from Surgery to Diagnosis might have a role name of "pre-operative diagnosis". This mechanism, however, does not allow binding to the a coded terminology such as LOINC. This property provides the ability to bind the diagnosis to such a code.

diagnosisCodeContains a code that most closely identifies the condition or the diagnosis. This code will come from one of several commonly used coding systems, depending on the branch of medicine involved (e.g., clinical medicine, dentistry, mental health), and on the purpose (e.g., clinical, billing). The code will likely come from one of the following: Structured Nomenclature for Medicine (SNOMED), International Classifications of Diseases (ICD), Diagnostic and Statistical Manual of Mental Disorders (DSM)."Reason the encounter takes place, as specified using information from another resource. For admissions, this is the admission diagnosis. The indication will typically be a Condition (with other resources referenced in the evidence.detail), or a Procedure." - HL7 FHIR, Encounter.diagnosis.condition"The diagnosis." - HL7 FHIR, Claim.diagnosis.diagnosis[x]. Note that FHIR can be a code or a pointer to a Condition."Diagnosis code." - PCORnet Common Data Model, Encounter.DX."Diagnosis code type." - PCORnet Common Data Model, Encounter.DX_Type. Possible values include: ICD-9-CM; ICD-10-CM; ICD-11-CM; SNOMED-CT; No information; Unknown; Other. Note that in the FHIM, this would be known from the codeSystem of the Code datatype.
diagnosisModifierContains a "modifier" that more precisely identifies the condition or the diagnosis. Some coding schemes, such as the International Classifications of Diseases version 9, support the notion of a "modifier", while others do not. This property is only to be used when the code property is using a coding scheme that supports a modifier.
