What is the electronic file of all charges that might be posted to a patient account known as?

The electronic file of all charges that might be posted to a patient account is known as the Chargemaster. The Chargemaster serves as a comprehensive list that includes all billable services, procedures, and supplies provided to patients within a healthcare facility. It is crucial for the revenue cycle as it sets the foundation for billing practices and ensures that all services rendered are captured and appropriately billed.

The Chargemaster not only lists charges but also includes codes that correspond to procedures or services, which are essential for accurate claim submission to payers. This standardized file helps facilitate the billing process and ensures compliance with regulatory requirements, as it reflects the pricing structure that the institution uses for its services.

In comparison, other options do not pertain to the concept described in the question. A Claim Rejection relates to the denial of a submitted claim by a payer. The Clinical Laboratory Improvement Amendment refers to regulations governing laboratory testing, and a Community Health Needs Assessment pertains to the identification of community health needs rather than financial billing processes. Thus, the Chargemaster is the appropriate term for the context of the question.
