No. A durable power of attorney cannot be used to make medical decisions. It authorizes your agent to handle financial and legal matters only — paying bills, managing accounts, dealing with real estate and insurance — and stops at the door of the treatment room. To let someone consent to surgery, refuse life-sustaining care, or choose your doctors when you cannot speak for yourself, you need a separate document, usually called a healthcare power of attorney, medical power of attorney, or healthcare proxy depending on the state. Most people need both.
What a Durable Power of Attorney Actually Authorizes
A durable power of attorney is a document in which you (the principal) name someone (the agent) to handle your financial and legal affairs. The word “durable” matters: it means the agent’s authority survives your incapacity. A non-durable power of attorney ends the moment you become unable to make your own decisions, which is exactly when your agent is needed most.
A financial agent’s typical work includes managing bank and investment accounts, paying household bills and debts, filing tax returns, collecting income or benefits owed to you, buying or selling real estate, and dealing with insurance policies. Some documents also grant gifting authority, though many cap gifts at the federal annual gift tax exclusion — $19,000 per recipient in 2026 — and some bar the agent from making gifts to themselves entirely.1Internal Revenue Service. Frequently Asked Questions on Gift Taxes
What the document cannot do is authorize your agent to consent to surgery, refuse a medical treatment, choose your physicians, decide where you receive care, or make end-of-life decisions. Those powers live in a different document, no matter how broadly your durable power of attorney is worded.
The Documents That Actually Cover Medical Decisions
Three documents address healthcare decision-making when you can’t communicate your own wishes. They work differently and serve different purposes.
Healthcare Power of Attorney
A healthcare power of attorney (also called a medical power of attorney or healthcare proxy) names a specific person to make medical decisions for you when you’re incapacitated. Your agent can consent to or refuse treatments, choose your doctors, decide where you receive care, access your medical records, and communicate with your healthcare team.2National Institute on Aging. Advance Care Planning: Advance Directives for Health Care You can also give the agent authority over end-of-life decisions, pain management, and comfort care. This is the document that does the real work when a medical situation nobody anticipated arises.
Living Will
A living will takes a different approach. Instead of naming a decision-maker, it records your specific preferences for medical treatment — particularly around life-sustaining care. You state whether you want mechanical ventilation if you can’t breathe on your own, tube feeding if you can’t eat, CPR if your heart stops, and similar interventions.3National Institute on Aging. Preparing a Living Will A living will speaks for you directly, but it can only address scenarios you thought of in advance. It cannot adapt to unexpected situations the way a live decision-maker can.
Advance Directive
Advance directive is the umbrella term for both a healthcare power of attorney and a living will. Some states combine them into a single form; others keep them separate. Having both gives you the strongest coverage: the living will records your known preferences, and the healthcare agent handles everything else.2National Institute on Aging. Advance Care Planning: Advance Directives for Health Care
POLST or MOLST
A POLST (Portable Medical Order for Life-Sustaining Treatment, called MOLST in some states) is an actual medical order signed by a healthcare provider after discussing your condition and treatment options. It carries the force of a medical order, meaning emergency medical technicians must follow it. EMTs cannot honor a living will or healthcare power of attorney at the scene; they’re trained to stabilize and transport. A POLST travels with you across care settings and gives first responders clear, immediately actionable instructions. POLSTs are designed for people who are seriously ill or medically frail, not for healthy adults doing general planning.
Where Financial and Medical Authority Overlap
Even though a financial agent has no authority over your medical treatment, they still end up interacting with the healthcare system. Paying hospital bills, handling health insurance claims, filing through Medicare or Medicaid, and sorting out what’s left unpaid after insurance is financial work that falls within a durable power of attorney’s scope. Your agent writes the checks. They do not decide what treatment the checks pay for.
Medical records are more complicated. Under HIPAA, healthcare providers generally cannot share your protected health information with someone just because they hold a financial power of attorney. Your healthcare power of attorney agent is typically treated as your personal representative with broad access to your records, while your financial agent may only receive the minimum information necessary to process a payment. If you want your financial agent to have fuller access to billing details or insurance records, you may need a separate HIPAA authorization form naming them specifically.
When different people serve as financial agent and healthcare agent, friction can arise. Your healthcare proxy might select a particular care facility while your financial agent controls the funds to pay for it. In that situation, the financial agent is generally obligated to use your funds to pay for the care decisions your healthcare agent has made, not to override those decisions by refusing to write the check. Choosing agents who communicate well, or naming the same trusted person for both roles, avoids most of these conflicts.
What Happens if You Only Have the Financial Document
If you become incapacitated with a durable power of attorney but no healthcare directive, your family does not automatically get the right to make medical decisions for you. Someone — usually a spouse or adult child — must petition a court to be appointed as your guardian or conservator. Guardianship is the legal system’s backup plan, and it is expensive, slow, and public.
The process involves filing a petition, paying court fees and attorney costs, potentially hiring a medical expert to evaluate your capacity, and attending one or more hearings. It can take weeks or months. The court decides who gets appointed, and the appointee may not be the person you would have chosen. Once in place, a guardian typically must file regular accountings with the court and may need court permission for major decisions. The Department of Justice has described guardianship as a last resort because it strips away the individual’s legal rights and independence.4U.S. Department of Justice. Elder Justice Initiative – Guardianship: Less Restrictive Options
Spending a few hundred dollars on the right documents now avoids spending thousands on a guardianship proceeding later, and it keeps the decision about who speaks for you in your own hands.
Getting Both Documents in Place
At a minimum you need two documents: a durable power of attorney for financial matters and a healthcare power of attorney (or an advance directive that includes one). A living will rounds out the package.
You must be mentally competent when you sign. You need to understand what the documents do and who you are appointing. If capacity might be questioned, a physician’s written evaluation dated the same day you sign can prevent challenges later.
Choose your agents carefully. Pick someone you trust completely for each role and name at least one backup agent in case your first choice cannot serve. Confirm they are willing to take on the responsibility before you finalize anything. The same person can serve in both roles, or you can split them; splitting works well when one relative is better with money and another is better with medical judgment, provided they can cooperate.
Every state sets its own execution rules. Most require your signature, and many require notarization, witnesses, or both. Witness requirements vary — some states require two witnesses who are not related to you and have no financial interest in your estate. State bar association websites and legal aid organizations often provide free statutory forms that meet a state’s specific requirements. Attorney-drafted documents typically run between $250 and $500 for straightforward cases, with more complex plans costing more.
After signing, distribute copies to everyone who needs them: your financial agent, your healthcare agent, your primary care physician, your bank, your attorney, and at least one trusted family member. Talk to your agents about your wishes; a document they’ve never read won’t help anyone during a crisis. Review everything every few years, after any major life event like a marriage, divorce, or move to a new state, and whenever your preferences about care or your trust in your chosen agents changes.
