Which organization provides RAT-STATS?

The correct answer is B, as the Office of Inspector General (OIG) is indeed the organization responsible for providing RAT-STATS, which stands for "Statistical Software for Health Care Auditing." This software tool is designed to assist auditors in the health care sector to perform statistical sampling and analysis efficiently.

RAT-STATS is particularly useful for auditors conducting reviews of Medicare and Medicaid services, allowing for effective data analysis and ensuring compliance with regulations. The OIG, as part of the U.S. Department of Health and Human Services, aims to combat fraud, waste, and abuse in health care and provides resources and tools, such as RAT-STATS, to facilitate this task.

Other organizations listed do not provide RAT-STATS. The Centers for Medicare & Medicaid Services (CMS) primarily oversees policies and programs related to Medicare and Medicaid but does not focus on statistical tools. The American Medical Association (AMA) is involved in physician advocacy and education rather than statistical auditing. The World Health Organization (WHO) focuses on international public health issues and does not provide tools related to health care auditing in the same context as the OIG.
