ADT^A44 — Move Account Information

Move an account (Patient Account Number) from one patient to another. Typical case: account opened by mistake under the wrong patient.

Purpose

A44 moves an account (Patient Account Number) from one patient to another. PID carries the new target patient, MRG identifies the origin patient (MRG-1) and the account concerned (MRG-5). No merge: both patients remain independent.

Common errors

• Confusion with A41: A41 merges two accounts keeping one patient, A44 moves an account to a different patient.
• MRG-5 missing: the receiver does not know which account to move.
• Pre-existing DFTs orphan: the account's financial transactions must follow.
