If you receive a fax that is labeled confidential and was intended for another number, what you should do is contact the sender of the fax and inform them of the mistake. The fax you have received in error should be destroyed without delay. If the sender of the fax is a member of a Covered Entity´s workforce and the fax contains PHI, you should also inform them that the fax has been destroyed so they can make an informed decision as to whether the error constitutes a reportable HIPAA violation.
