HIPAA was enacted in 1996 to protect patients' health insurance and personal health information. It requires covered entities like healthcare providers, insurers, and their business partners to implement procedures to protect protected health information (PHI), such as patients' medical records. These entities must designate a privacy officer, train staff on privacy policies, and obtain patient acknowledgement of their privacy practices. HIPAA also dictates exceptions for uses of PHI, such as for treatment, payment, healthcare operations, and with patient authorization.
