Yes. The Privacy Rule gives individuals the right to revoke, at any time, an Authorization they have given. The revocation must be in writing, and is not effective until the covered entity receives it. In addition, a written revocation is not effective with respect to actions a covered entity took in reliance on a valid Authorization, or where the Authorization was obtained as a condition of obtaining insurance coverage and other law provides the insurer with the right to contest a claim under the policy or the policy itself.
The Privacy Rule requires that the Authorization must clearly state the individual’s right to revoke; and the process for revocation must either be set forth clearly on the Authorization itself, or if the covered entity creates the Authorization, and its Notice of Privacy Practices contains a clear description of the revocation process, the Authorization can refer to the Notice of Privacy Practices. Authorization forms created by or submitted through a third party should not imply that revocation is effective when the third party receives it, since the revocation is not effective until a covered entity which had previously been authorized to make the disclosure receives it.
