3.2.6 ADT/ACK - change an outpatient to an inpatient (event A06)

An A06 event is sent when a patient who was present for a non-admitted visit is being admitted after an evaluation of the seriousness of the patient’s condition. This event changes a patient’s status from non-admitted to admitted. The new patient location should appear in PV1-3-assigned patient location, while the old patient location (if different) should appear in PV1-6-prior patient location. The new patient class should appear in PV1-2-patient class.

It will be left to implementation negotiation to determine whether disparate systems merely change the patient class, or close and open a new account. The current active account number should appear in PID-18-patient account number; the prior account number can be included optionally in MRG-3-prior patient account number. This arrangement is not intended to be a type of merge, but the MRG segment is used here for MRG-3-prior patient account number.

The fields, included when this message is sent, should be the fields pertinent to communicate this event. When other important fields change it is recommended that the A08 (update patient information) event be used instead.
