Advance Directive vs. Living Will vs. Healthcare Proxy: The Difference in One Paragraph

"Does your mom have an advance directive?" and "does your mom have a living will?" sound like two different questions. Most of the time, they're not. The confusion is common enough that even people who work in healthcare mix these terms up in casual conversation.

"Advance directive" is the umbrella term. It covers any document that states your medical wishes in advance, in case you can't speak for yourself. A living will is one specific kind of advance directive. It spells out what treatments you do or don't want (ventilators, feeding tubes, resuscitation) in specific scenarios.

A healthcare proxy, also called a healthcare power of attorney, is a different kind of advance directive. Instead of listing your wishes in advance, it names a person to make medical decisions on your behalf. That person decides in the moment, based on situations a living will couldn't have predicted. Most people benefit from having both: a living will for the decisions you can anticipate, a healthcare proxy for the ones you can't.

None of this needs to be memorized. What's actually useful is knowing which ones exist for you or someone you're caring for, and where they're kept. The terminology confusion disappears the moment the actual documents are findable.
