Which act holds entities liable for submitting false claims to the federal government?

The False Claims Act is the correct choice because it specifically addresses the issue of fraud against the federal government by holding individuals and entities accountable for submitting false claims for payment. This act allows for both civil and criminal penalties against those who knowingly submit fraudulent claims or assist in doing so. It is often utilized in healthcare to combat fraudulent billing practices.

The False Claims Act also includes provisions for whistleblower protections, enabling individuals to report fraudulent activities without fear of retaliation. This aspect encourages more people to come forward with information about wrongdoing.

In contrast, the other acts mentioned have different focuses. The Anti-Kickback Act pertains to prohibiting the exchange of remuneration for referrals in healthcare services, the Stark Act regulates physician self-referral, and the Sunshine Act promotes transparency in healthcare by requiring the disclosure of financial relationships between healthcare providers and pharmaceutical companies. Each of these acts addresses specific issues but does not directly impose liability for submitting false claims to the federal government like the False Claims Act does.
