Yes. The Privacy Rule permits covered entities to maintain more than one type of patient directory, and to maintain multiple versions of them, provided that the other requirements at 45 CFR 164.510(a) – PDF also are followed. For instance, emergency rooms that maintain directory information, even though separate from, or in a form different than, the hospital directory of admitted patients, may still disclose the information consistent with the requirements of the Privacy Rule.
