Title II of the Health Insurance Portability and Accountability Act (HIPAA) specifically addresses the protection of patients' privacy and the security of their health information. This part of HIPAA mandates healthcare providers and other covered entities to implement necessary safeguards to ensure that individuals' medical records and personal health information are kept confidential and secure from unauthorized access.

Confidentiality is crucial in fostering trust between patients and healthcare providers, enabling patients to share sensitive information without fear of disclosure. HIPAA emphasizes the importance of protecting this information to maintain patient privacy rights.

While autonomy, informed consent, and health insurance coverage are important aspects of healthcare, Title II of HIPAA focuses primarily on the privacy and security of health information, making confidentiality the most relevant answer in this context.
