"Diagnosis"
Data elements that meet criteria using this datatype should document the Condition/Diagnosis/Problem and its corresponding value set. The onset dateTime corresponds to the implicit start dateTime of the datatype and the abatement dateTime corresponds to the implicit stop dateTime of the datatype. If the abatement dateTime is not present, then the diagnosis is considered to still be active. When this datatype is used with timing relationships, the criterion is looking for an active diagnosis for the time frame indicated by the timing relationships.
Timing: The prevalencePeriod references the time from the onset date to the abatement date.
