The HIPAA Privacy Rule requires covered entities to obtain an individual's written authorization for any use or disclosure of protected health information (PHI) that is not for treatment, payment, or health care operations or otherwise permitted or required by the Privacy Rule. However, there are some exceptions to the authorization requirement for certain public interest-related activities, such as disclosing health information for public health activities, reporting child abuse, or treating a medical emergency. These exceptions are intended to balance the privacy interests of individuals with the public interest in protecting health and safety, promoting quality health care, and ensuring compliance with the law. Disclosing health information needed to pay a third party billing administrator is not one of the exceptions to the authorization requirement, as it is considered a payment activity that falls under the general rule of requiring authorization. Therefore, it is the correct answer to the question.
