Answer:

No, the Privacy Rule does not require a covered entity to enter into business associate contracts with organizations, such as the US Postal Service, certain private couriers and their electronic equivalents that act merely as conduits for protected health information. A conduit transports information but does not access it other than on a random or infrequent basis as necessary for the performance of the transportation service or as required by law. Since no disclosure is intended by the covered entity, and the probability of exposure of any particular protected health information to a conduit is very small, a conduit is not a business associate of the covered entity.
