Encounter diagnosis in CCD?

[Rob Rucker]

Looking at several examples of encounter data in CCDs, I have not been able to find a consistent place to parse out encounter diagnoses for outpatient visits. For inpatient visits, there is always (as far as I can tell) a "Discharge Diagnosis," but the encounter diagnoses for outpatient visits does not seem to be consistently listed in CCDs. Will I have to use the Condition resource to get encounter-level diagnoses for outpatients? Is there a recommended method I should use?
