Ways to report potential Fraud, Waste, and Abuse (FWA) include:

• A. Special Investigations Units (SIUs)
• B. Compliance hotlines
• C. Public notices
• D. Email to staff

Answer: (A)

Special Investigations Units are the designated investigative arm within many organizations that handle suspected fraud, waste, and abuse. They provide a formal intake and pathway for turning a concern into an official investigation, ensuring reports are documented, confidentiality is protected, and evidence is preserved. They coordinate next steps, escalation, and action, which is why this unit is the most appropriate channel for reporting FWA. While compliance hotlines exist as a way to raise concerns, they typically feed into the SIU or compliance function for investigation, and public notices or simply emailing staff do not provide the structured intake and investigative process needed to address FWA.
