3.2.7 ADT/ACK - change an inpatient to an outpatient (event A07)

An A07 event is sent when a patient who was admitted changes his/her status to "no longer admitted" but is still being seen for this episode of care. This event changes a patient from an "admitted" to a "non-admitted" status. 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.

We leave it 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 field 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. The MRG segment is only used here for MRG-3-prior patient account number. PV1-19-visit number can also be changed during this event.

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.
