Which statement best describes the Office of Inspector General's (OIG) role in Medicare compliance?

• A. It solely handles hospital billing disputes.
• B. It Oversees program integrity; conducts audits and investigations; issues advisory opinions; maintains LEIE; guides compliance program expectations.
• C. It regulates patient safety.
• D. It determines physician licensure.

Answer: (B)

This describes the Office of Inspector General’s role in Medicare compliance, focusing on safeguarding the program from fraud, waste, and abuse. The OIG oversees program integrity across Medicare by setting and enforcing standards, conducting audits and investigations to uncover improper payments or vulnerable processes, and issuing advisory opinions that spell out OIG’s official positions on proposed arrangements and practices that could raise compliance concerns. It also maintains the List of Excluded Individuals/Entities (LEIE), which helps organizations screen out providers and entities that have been excluded from federal health care programs, and it guides providers on what compliant behavior looks like by outlining expectations for effective compliance programs. Together, these functions create a comprehensive framework for detecting issues, guiding safe practices, and promoting strong internal controls within Medicare programs.

Other roles listed don’t fit because patient safety regulation is handled by different CMS-related bodies and health system regulators, not the OIG. Physician licensure is determined by state medical boards, not by the OIG. And while the OIG does pursue issues related to billing and improper payments, its mandate is broader than resolving hospital billing disputes alone, encompassing system-wide program integrity and compliance guidance.
