Final answer:
The sequence of processes to progress a patient account from creation to closing is called audit trail.
Step-by-step explanation:
Audit trail is the sequence of processes to progress a patient account from creation to closing. In the healthcare industry, patient accounts are created when a patient receives medical services, and they go through several stages until they are closed. These stages typically include registration, billing, payment posting, and insurance verification. Each step is documented and forms an audit trail, providing transparency and accountability for the financial transactions related to the patient account.
