Restate from JIRA CQM-1781 --The ED visit start should be based on arrival to the ED, the timestamp in the EHR that most closely captures the date and time the patient arrives to the ED. The ED visit end should be based on when the patient physically leaves the ED, the timestamp in the EHR that most closely captures the date and time the patient leaves the ED.

For ED departure our EHR uses the earliest of ED event departed from ED or patient admitted. The date/time a patient becomes an inpatient can be before the patient physically departs from the ED. This is for billing purposes where the patient's inpatient admission can be started in the ED while the patient physically remains in the ED. Will the logic use the date/time of admission instead of the ED departure? Will this fail CDAC validation?
