One of the most essential documents every adult should have—regardless of age or health status—is an advance health care directive, also commonly known as a living will, health care proxy, or health care power of attorney. Despite the slightly different names, these terms often refer to the same legal instrument; a document that combines two critical components of health care planning—an instructive directive and a proxy directive.
What Is an Advance Health Care Directive?
An advance health care directive typically includes two parts: an instructive directive and a proxy directive. An instructive directive outlines the patient’s wishes for medical care in specific situations. For example, someone may state, “If I have no brain activity, I do not want to be kept alive by extraordinary measures such as a ventilator.” This component is what most people refer to when they use the term living will. A proxy directive designates a trusted individual—often a spouse, child, or close friend—to make medical decisions on the patient’s behalf if the patient becomes incapacitated. A typical directive might say, “If I am unable to make decisions for myself, I appoint my wife to do so. If she is unavailable, I appoint my son, John.”
Today, these two components are usually combined into a single document. Whether it’s called a living will, health care proxy, or health care power of attorney, it functions as a comprehensive advance directive.
Why It Matters
Without an advance directive, no one—not even your spouse—has legal authority to make medical decisions for you if you’re incapacitated. While hospitals may consult with family members in emergencies, they are under no legal obligation to follow their wishes unless an advance directive is in place.
An advance directive only becomes effective when the patient is no longer able to make decisions for themselves. As long as the patient can speak, nod, gesture, or in any way express disagreement, their wishes override those of any proxy—even if the proxy was officially designated. This reflects a core principle of health care law: the patient’s autonomy is paramount.
HIPAA and Medical Privacy
Another key feature of the advance directive is the ability to authorize your proxy to access your private medical records. Under the Health Insurance Portability and Accountability Act (HIPAA), hospitals, doctors, and insurance companies are prohibited from sharing your health information without your explicit permission. Including a HIPAA release within your advance directive ensures your proxy can communicate effectively with your medical team and advocate for your care.
Organ Donation: A Decision That Can Save Lives
An often-overlooked section of the advance directive is the option to specify whether you would like to donate your organs. This decision can be life-saving for others. Currently, more than 100,000 people in the U.S. are waiting for an organ transplant, yet only about 16,000 deceased individuals donate organs each year. Every day, thirteen people on the donor list die for lack of donated organs. A common misconception is that doctors won’t work as hard to save you if you’re listed as a donor. This is simply untrue—medical teams working to save lives are entirely separate from those involved in organ procurement.
A Simple Step That Makes a Big Difference Whether you’re young or old, healthy or managing chronic conditions, this document ensures that your voice is heard—even if you can’t speak for yourself. It’s a vital part of any adult’s estate planning—and it’s one of the greatest gifts you can give to your family and your future self.
Medical emergencies rarely happen when families feel prepared for them. An advance health care directive can provide guidance during difficult moments and help ensure that important decisions reflect your wishes rather than someone else’s assumptions.
