DG1-3 (Diagnosis Code)

is equivalent to

diagnosis.condition(Condition.code)

DG1-4 (Diagnosis Description)

is equivalent to

diagnosis.condition(Condition.code.text)

Doesn't warrant mapping

DG1-5 (Diagnosis Date/Time)

is equivalent to

diagnosis.condition(Condition.onsetDateTime)

Should confirm that these two concepts are equivalent. Condition.recordedDate is also available

DG1-6 (Diagnosis Type)

is equivalent to

diagnosis.role

DG1-15 (Diagnosis Priority)

is equivalent to

diagnosis.rank

Could contribute to Condition.category or be a new extension

DG1-16 (Diagnosing Clinician)

is equivalent to

diagnosis.condition(Condition.asserter(Practitioner)

While DG1-16 can repeat, we are not aware of instances where this is used. Until such time, we will not yet establish an agreed to method to communicate the extra repeats in FHIR.

DG1-19 (Attestation Date/Time)

is equivalent to

diagnosis.condition(Condition.extension[1].url)

DG1-19 (Attestation Date/Time)

is equivalent to

diagnosis.condition(Condition.extension[1].valueDateTime)

It is unclear whether to use recorded or asserted date. What is your opinion?

DG1-19 (Attestation Date/Time)

is equivalent to

diagnosis.condition(Condition.recordedDate)

It is unclear whether to use recorded or asserted date. What is your opinion?
