Which characteristic is required in a HIPAA authorization?

A characteristic required in a HIPAA authorization is that it must use "plain language" to ensure comprehension by the data subject. This requirement is crucial because HIPAA aims to protect individuals' privacy and ensure that they understand what they are consenting to regarding the use and disclosure of their health information. The regulation emphasizes the need for clear communication, so individuals can make informed decisions about their health data.

Using plain language helps to avoid misunderstandings and allows individuals to grasp the potential risks and implications of providing their authorization. This approach aligns with the overall goals of transparency and empowerment in health care, enabling individuals to be active participants in decisions about their personal health information.

Other answer choices suggest different approaches that do not align with HIPAA's goals of accessibility and clarity. For instance, requiring signatures in the presence of a legal witness may not be a standard practice for all situations under HIPAA, and using technical language can hinder understanding rather than enhance it. Furthermore, a lengthy document could potentially confuse the data subject, making it less likely they will fully comprehend the information being presented, which is contrary to the intention of informed consent.
