description: This section contains details about the patient’s advance healthcare directives, including references to supporting documents such as Living Wills, Healthcare Power of Attorney, Personal Advance Care Plans, DNR Orders, and Portable Medical Orders. Each type of advance directive document is represented by an individual Advance Directive Observation within a single Advance Directive Existence Observation.

Additionally, the Advance Directive Observation may include information about the document’s author and any individuals who verified the information with the patient or their healthcare agent.
