The Office for Civil Rights enforces several rules under HIPAA including the Privacy Rule, Security Rule, and Breach Notification Rule. The Health Insurance Portability and Accountability Act (HIPAA) of 1996 aims to improve the efficiency and effectiveness of the US healthcare system through standards for electronic health information exchange and rules regarding health insurance coverage continuity and fraud prevention. HIPAA places limits on sharing confidential health information, establishes patient rights over their data, and implements safeguards for electronic protected health information.
