Which act enhances penalties for violations related to organized crime?

The RICO Act, or the Racketeer Influenced and Corrupt Organizations Act, is the correct choice because it was specifically designed to combat organized crime in the United States. This legislation allows for the prosecution of individuals involved in organized crime who participate in a pattern of racketeering activity, which includes a variety of criminal offenses such as bribery, extortion, fraud, and more. The RICO Act enhances penalties by enabling harsher sentences and the possibility of forfeiting assets gained through criminal activities, thus creating a powerful tool for law enforcement against organized crime syndicates.

The other choices do not fit the description provided in the question. The False Claims Act (FCA) is primarily associated with fraud against the federal government, especially in healthcare contexts. The Health Insurance Portability and Accountability Act (HIPAA) focuses on patient confidentiality and data security rather than organized crime. The Stark Law addresses physician self-referral practices in healthcare but is unrelated to organized crime. Therefore, the RICO Act is uniquely positioned to address organized crime and its associated penalties.
