HIPAA Fundamentals is the conceptual baseline. The articles below cover what HIPAA is (the Privacy Rule, Security Rule, Breach Notification Rule, and Enforcement Rule, all under the broader 1996 statute), who it applies to (covered entities, business associates, and the increasingly important hybrid-entity question), and the core terms that drive every downstream compliance decision (ePHI, minimum necessary, addressable vs required, business associate). Practices new to HIPAA should start here; experienced staff use these as reference for clarification.
