What main document will Sandra Keller analyze to determine compliance in her auditing responsibilities?

The main document that Sandra Keller will analyze to determine compliance in her auditing responsibilities is the utilization report. Utilization reports provide critical insights into how healthcare resources are used, offering data on procedures, services rendered, and the frequency of these services. This information is essential for evaluating whether the medical services provided are in line with established compliance guidelines and regulations.

By reviewing the utilization report, auditors can check for adherence to medical necessity for services, appropriate billing practices, and ensure that the care provided aligns with the standards of practice. Such reports are key in identifying any discrepancies that may signal risks for non-compliance or areas needing improvement, making them vital for Sandra's effective auditing process.

While other documents, such as patient medical histories, may contain important information about individual patient care and treatment, they do not provide the broader perspective necessary for assessing compliance across the healthcare facility. Staff training manuals and financial statements also have relevance but are not as directly tied to compliance with service utilization as the utilization report is.
