What is the definition of use in Hipaa?

In the context of HIPAA (Health Insurance Portability and Accountability Act), "use" refers to the internal handling of protected health information (PHI) by a covered entity, such as a healthcare provider, health plan, or healthcare clearinghouse. This includes any actions taken by the covered entity to access, share, or manage PHI for treatment, payment, or healthcare operations. Essentially, it encompasses the ways in which an entity operates with PHI within its own organization.
