HIPAA requires healthcare providers to protect individuals' protected health information (PHI). PHI includes any health information like names, dates, diagnoses, and other identifiable details. HIPAA sets rules for appropriate access, use, and disclosure of PHI. Violations can result in criminal penalties such as fines up to $250,000 or imprisonment up to 10 years. The document reviews key HIPAA concepts like what is considered PHI, how PHI can be used, and requirements for safeguarding electronic and written PHI.
