This document provides a decision tree to determine whether a business associate agreement is required. It asks a series of yes or no questions about the use of protected health information and the role of individuals accessing the information to establish whether an agreement is necessary for disclosure of data. If the individual is a healthcare provider seeking information for treatment, a member of the provider's workforce, or only a conduit of incidental information, then an agreement is not required. For all other cases, an agreement is required.
