Which of the following provides legal protection from prosecution for a specific party?

The OIG Advisory Opinion provides legal protection for a specific party by offering a formal response to a request for guidance regarding the legality of a proposed transaction or arrangement under the Federal anti-kickback statute or other healthcare law. When the Office of Inspector General (OIG) issues an advisory opinion, it can essentially offer a "safe harbor" for the entity seeking the opinion if the OIG determines that the proposed actions would not result in criminal prosecution or civil sanctions.

This legal protection can allow parties to proceed with their proposed arrangements with reduced fear of legal repercussions, as long as they operate within the confines of the opinion provided by the OIG.

In contrast, the other options, while important in healthcare compliance, do not provide this specific legal shielding from prosecution. A Corporate Integrity Agreement is more of a compliance framework set forth after an organization has been found to have engaged in wrongdoing, while a Fraud Hotline serves as a reporting mechanism for unethical behaviors. A Risk Assessment Report helps identify risks but does not confer legal protection.
