The Privacy Rule permits, but does not require, a covered entity voluntarily to obtain patient consent for uses and disclosures of protected health information for treatment, payment, and health care operations. Covered entities that do so have complete discretion to design a process that best suits their needs.
An authorization is a detailed document that gives covered entities permission to use protected health information for specified purposes, which are generally other than treatment, payment, or health care operations, or to disclose protected health information to a third party specified by the individual. An authorization must specify a number of elements, including a description of the protected health information to be used and disclosed, the person authorized to make the use or disclosure, the person to whom the covered entity may make the disclosure, an expiration date, and, in some cases, the purpose for which the information may be used or disclosed.
The Privacy Rule requires authorization for uses and disclosures of protected health information not otherwise allowed by the Rule. Where the Privacy Rule requires patient authorization, voluntary consent is not sufficient to permit a use or disclosure of protected health information unless it also satisfies the requirements of a valid authorization.
