When a Medicare provider commits fraud, which entity conducts the investigation?

Fraud committed by a Medicare provider is primarily investigated by the Office of the Inspector General (OIG). This entity holds the responsibility for both overseeing and investigating various forms of fraud and abuse in federal healthcare programs, including Medicare and Medicaid. The OIG has the authority to conduct audits, inspections, and investigations related to fraud, ensuring that the integrity of the healthcare system is maintained and that taxpayer dollars are not being misused.

The other entities mentioned may have roles in the broader context of healthcare oversight or law enforcement, but the OIG specifically focuses on the investigation of fraudulent activities within Medicare. This specialization allows the OIG to effectively identify, investigate, and prosecute fraudulent claims, protecting both patients and the government from dishonest practices.
