Which document specifies what medical interventions a patient does not want?

The document that specifies what medical interventions a patient does not want is a Living Will. A Living Will is a legal document that outlines a person's preferences regarding medical treatment in situations where they are unable to communicate their wishes, particularly at the end of life or in critical medical situations. It details the specific types of medical interventions a person does not want, such as life-sustaining treatments like resuscitation or mechanical ventilation.

This choice differentiates itself from other relevant documents like an Advance Directive, which actually encompasses a broader scope that includes both preferences for medical treatment and the appointment of a medical decision-maker. While a Medical Power of Attorney gives someone the authority to make healthcare decisions on behalf of the patient, it does not directly specify the patient's wishes regarding specific interventions. A Health Insurance Policy primarily relates to coverage and payment for medical services but does not convey a patient's treatment preferences.
