ADT^A04

ADT/ACK - Register a patient

Patient Administration
An A04 event signals that the patient has arrived or checked in as a one-time, or recurring outpatient, and is not assigned to a bed. One example might be its use to signal the beginning of a visit to the Emergency Room (= Casualty, etc.). Note that some systems refer to these events as outpatient registrations or emergency admissions. PV1-44 - Admit Date/Time is used for the visit start date/time.

The ROL - Role Segment is used in this message to communicate providers not specified elsewhere. Person level providers with an ongoing relationship are reported in the ROL segment following the PID/PD1 segments. Providers corresponding to the PV1 data are reported in the ROL segment following the PV1/PV2 segments. Providers related to a specific procedure are reported in the ROL segment following the PR1 segment. Providers related to a specific insurance are reported in the ROL segment following the IN1/IN2/IN3 segments. To communicate the begin- and end-date of the provider, use the ROL-5 - Role Begin Date/Time and the ROL-6 - Role End Date/Time in the ROL segment, with the applicable ROL-3 - Role Code. Refer to Chapter 15 for the definition of the ROL segment.
