Which HIPAA rule involves technical aspects of electronic transactions?

The Transaction Rule under HIPAA specifically focuses on the standards for electronic health care transactions. It establishes the framework for how electronic health information is exchanged between health care providers, payers, and other entities involved in health care. This rule defines the required formats and transaction types, ensuring that consistent and secure electronic communication occurs across the healthcare system. By providing a standardized approach, the Transaction Rule aims to streamline processes, reduce administrative costs, and improve the efficiency of health care transactions.

The other choices focus on different aspects of HIPAA regulations; for example, the Privacy Rule deals with the protection of individual health information and the circumstances under which it can be disclosed, while the Security Rule sets standards for safeguarding electronically protected health information. The Liability Rule, on the other hand, is not a recognized rule under HIPAA.
