The Office of Inspector General (OIG), part of the U.S. Department of Health and Human Services, works to prevent fraud, waste, and abuse in federal healthcare programs such as Medicare and Medicaid. To aid this effort, the OIG publishes Compliance Program Guidance (CPG), including a widely used set of guidelines for pharmaceutical manufacturers. This guidance outlines best practices for compliance, emphasizing proactive measures like clear policies, oversight, training, and regular assessments, to ensure adherence to key laws such as the Anti-Kickback Statute and the False Claims Act.
