This document provides an overview of HIPAA privacy rules regarding the use of protected health information (PHI). PHI includes individually identifiable health information such as medical history, health status, and identification details. Providers may use PHI without specific patient permission for treatment, payment, and healthcare operations. Treatment refers to discussing a patient's case with other providers, payment covers submitting insurance claims, and operations includes staff training. Anyone with access to PHI is liable if confidentiality is breached, and penalties for breaches include large fines, jail time, and loss of medical privileges.
