Do authorization to disclose protected health information must contain a expiration date?

Yes, authorization to disclose protected health information (PHI) must generally contain an expiration date or an event that will trigger its expiration. This requirement ensures that individuals are aware of how long their consent is valid and helps protect their privacy by limiting the duration of the disclosure. If no expiration date is specified, the authorization may be considered invalid under the Health Insurance Portability and Accountability Act (HIPAA) regulations.
