When people plan for medical decisions, two documents come up — a medical Power of Attorney and a living will. They sound similar and often live under the same umbrella (an “advance directive”), but they do different jobs. The clearest plans use both.
Medical Power of Attorney: names a person
A medical Power of Attorney (also called a healthcare Power of Attorney or healthcare proxy) appoints someone — your agent — to make medical decisions for you if you can’t make them yourself. The value is flexibility: a real person can weigh the actual situation, ask questions, and adapt as things change, guided by what they know you’d want.
Living will: writes down your wishes
A living will records your instructions for specific situations — often end-of-life care, life support, resuscitation, and similar choices. It speaks for you when you can’t, in your own words, so no one has to guess about the decisions that matter most to you.
Why you want both
They cover each other’s gaps. A living will can’t anticipate every scenario; your agent fills in the rest using your stated wishes as a guide. And your agent isn’t left guessing on the hardest calls, because your living will already put your values on paper. Together, they give your family clarity instead of conflict at the worst possible moment.
How this fits with a financial Power of Attorney
These are the *medical* side. A financial Power of Attorney is a separate document for money and property. Ideally the same person (or a closely aligned team) handles both, so decisions don’t collide — see Power of Attorney vs. an advance directive for how the pieces fit.
Every adult should have these in place — yes, even young adults. To set them up correctly for your state, the POA Handbook walks you through it.
