Which organization focuses on investigating alleged privacy violations?

The Office of Civil Rights (OCR) is the correct choice because it is specifically tasked with enforcing federal civil rights laws that prohibit discrimination in programs and activities that receive federal financial assistance, as well as ensuring compliance with the Health Insurance Portability and Accountability Act (HIPAA) privacy and security rules. The OCR investigates complaints regarding violations of patient privacy and helps protect individuals' health information. Its primary focus is on overseeing and addressing issues related to privacy, making it the most relevant organization for investigating alleged privacy violations in the healthcare context.

While the other organizations listed have vital roles in the healthcare and legal systems—such as CMS, which administers health care programs; the Department of Justice, which addresses criminal activities including healthcare fraud; and the Federal Trade Commission, which protects consumers from deceptive practices—they do not primarily focus on privacy violations in the way that the Office of Civil Rights does. Their functions, while important, do not center exclusively on the enforcement of privacy regulations related to personal health information.
