Many people confuse a health care proxy with a power of attorney (POA). Both documents matter when you want clear plans for medical care and financial decisions. Without them, families often face disputes and delays during emergencies.

Lawyers and estate planners often explain the topic of health care proxy vs. power of attorney to clients so they understand the difference between medical and financial authority.

Before you have that conversation or get into planning a funeral, this guide explains what each document does, how they differ, and why you may need both.

Note: In most states, “health care proxy,” “health care power of attorney,” and “medical power of attorney” are just different names for the same medical decision-making document. You generally need one medical decision document plus a separate financial power of attorney for money/legal matters.

Exception: Florida uses “Designation of Health Care Surrogate” for the appointed medical decision-maker and reserves “health care proxy” for the default/fallback decision-maker when there is no named surrogate.

What Is a Health Care Proxy?

A health care proxy (also called a medical power of attorney or health care power of attorney, depending on your state) names a trusted person to make medical decisions if you cannot. You keep control until a clinician determines you lack capacity.

The agent can consent to or refuse treatments, choose providers, and make end-of-life decisions based on your wishes. In New York, the official term is “health care proxy.”

In Florida, the document is a “Designation of Health Care Surrogate,” while a “health care proxy” is a fallback when there is a designated surrogate.

A health care proxy gives your agent the authority to:

• Consent to or refuse medical treatments
• Select doctors and care providers
• Decide on end-of-life care based on your wishes

In states where a medical power of attorney and health care proxy are the same document, you do not need both. In states that treat them as separate, a health care proxy covers medical decision-making, while a durable POA typically covers finances.

What Is a Power of Attorney (POA)?

A power of attorney (POA) is a legal authorization that lets you appoint another person, known as an agent, to act on your behalf. The scope of authority depends on the type of POA you create. Some cover only financial or legal matters, while others extend to healthcare.

General Power of Attorney

A general POA gives your agent broad authority to manage your affairs. This often includes banking, signing contracts, paying bills, and handling property. Because it covers so many areas, it’s useful when you need someone to step in for everyday financial or legal tasks. 

However, a general POA usually ends if you become incapacitated and does not cover medical decisions unless specified.

Durable Power of Attorney

A durable POA remains in effect even if you lose the ability to make decisions. This makes it one of the most reliable tools for long-term planning. With a durable POA, your agent can continue managing your finances, property, and legal obligations without interruption.

It only ends at your death, if you revoke it, or if your agent resigns. Many people choose a durable POA to ensure stability and avoid court involvement if they become incapacitated.

Limited Power of Attorney

A limited POA, also called a special POA, restricts your agent’s powers to specific actions or timeframes. For example, you may authorize someone to complete a real estate transaction while you are abroad or handle business matters in your absence.

Because it grants narrow authority, a limited POA is useful for targeted needs rather than ongoing management of all affairs.

Medical Power of Attorney

A medical power of attorney is the same role/document that many states call a health care proxy or health care power of attorney (name varies by state). In Florida, the equivalent document is a Designation of Health Care Surrogate.

It ensures that medical treatment aligns with your preferences when you are unable to speak for yourself. In some states, a medical POA overlaps with or takes the place of a health care proxy.

This makes it a critical document for protecting your medical wishes and giving your agent access to the information they need to act in your best interest.

Include HIPAA authorization language in your medical POA so that your agent can access medical records when they need it.

Health Care Proxy Vs. Power of Attorney: Key Differences

A health care proxy, also called a medical power of attorney in some states, gives someone authority to make healthcare choices only if you cannot communicate.

By contrast, a financial or durable power of attorney authorizes someone to handle legal or financial matters, such as paying bills, managing property, or signing contracts. These roles are not interchangeable, which is why many people need both documents in place.

The timing also differs. It takes effect when your attending clinician (per state law) determines you lack decision-making capacity; some states require additional confirmation for life-sustaining treatment.

A power of attorney can begin immediately, stay effective through incapacity if durable, or “spring” into effect under specific conditions.

POAs end at death, while a health-care agent’s authority usually ends at death except for specific post-death authorizations (such as anatomical gifts) if allowed by state law and your form.

Because terminology varies by state, ‘health care proxy’ and ‘medical power of attorney’ may mean the same thing or be distinct. Always check your state’s forms to know whether you need one or both documents.

Note: As of December 2022, 46 states have default surrogate statutes. Always check your current state’s official forms and statutes, as these laws continue to evolve.

General and durable powers of attorney are not the same. A general POA ends when you become incapacitated, but a durable POA continues through incapacity until you revoke it or until death. Because of this difference, people usually discuss them separately.

You should compare the differences between a health care proxy vs. a power of attorney before completing these forms, since each grants different rights and takes effect under different conditions.

When Do You Need Both?

Most people benefit from having both a health care proxy and a power of attorney (POA). Together, they cover the full spectrum of needs in an emergency. The health care proxy ensures that medical decisions reflect your values, while the POA keeps your finances, property, and legal affairs in order.

Consider a few common scenarios:

• If a car accident lands you in the hospital, your health care proxy decides whether doctors should perform surgery, and your POA pays the rent and utilities.
• You are living with a progressive illness. As treatment decisions arise, your proxy consults with doctors about options, while your POA manages disability benefits, files insurance claims, and oversees investments.
• You are traveling abroad and become incapacitated. Your proxy works with the hospital on care decisions, while your POA handles business matters back home.

Without both documents, families may need to petition the court for guardianship or conservatorship. This process is slow, costly, and stressful, especially in the middle of a crisis. If you haven’t executed these documents, a court often must appoint a guardian/conservator to act.

Naming both a proxy and a POA avoids conflict, saves time, and ensures they carry out your wishes without delay.

How To Choose the Right Person for Each Role

Choosing the right person matters as much as filling out the paperwork. These roles carry serious responsibility, so focus on trust, reliability, and the ability to act under pressure.

Qualities of a Health Care Proxy

• Trustworthy and assertive, willing to honor your wishes even if others disagree
• Calm under pressure and comfortable speaking with doctors
• Available in emergencies and able to make quick, informed decisions
• Strong communicator who can explain your values and preferences clearly

Qualities of a Power of Attorney (POA)

• Financially responsible and organized
• Familiar with legal or financial matters, or willing to seek professional advice
• Honest and dependable, with no conflict of interest
• Reliable in handling complex or long-term responsibilities

Can One Person Serve Both Roles?

Yes, one person can serve as both your health care proxy and your POA. For many, appointing the same trusted person makes sense. However, consider the demands.

A single individual may face difficult medical and financial decisions at the same time, which can create conflict or overwhelm. Some people prefer to split the roles between two trusted individuals for balance.

Setting Up a Health Care Proxy and Power of Attorney

Establishing these documents requires the right forms and proper execution. Each state has its own rules, so it’s important to follow local requirements through these steps:

• Obtain forms: Download official state-specific forms or request them from your medical provider, attorney, or local health department. Hospitals often provide proxy forms during admissions.
• Complete and sign: Most states require adult witnesses, and some require notarization. Read instructions carefully to ensure validity.
• Store and share copies: Keep originals in a safe but accessible place. Provide copies to your proxy, your POA, your doctor, and close family members who might play a role in decision-making.
• Review regularly: Update these documents after major life events such as marriage, divorce, or a significant health diagnosis. Communicate your wishes clearly so your chosen agents understand their roles.

Common Misconceptions About Medical Proxy vs Power of Attorney

Many people misunderstand how a power of attorney and a health care proxy work. These myths can lead to gaps in planning and stress during emergencies.

Misconception 1: A durable POA and a general POA are the same

A general POA usually ends if you become incapacitated. A durable POA stays valid even when you cannot act for yourself. That durability makes it a better tool for long-term planning, but it only covers financial and legal matters unless it is specifically a medical POA.

Misconception 2: A spouse or child automatically has authority

Not always. Most states have default surrogate statutes that create a priority list, often beginning with a spouse or partner, then adult children, parents, siblings, and in some states, more distant relatives or close friends.

Over the past decade, some states have made new surrogate laws where none existed before. This means in those states, a spouse or child does not automatically have legal authority unless you formally name them.

Misconception 3: You lose control of your rights when you name a proxy

Naming a health care proxy or medical POA does not remove your rights. You keep decision-making authority as long as you are able to communicate. You can also revoke or update your proxy or POA at any time.

Misconception 4: Advance directives only matter at the end of life

Advance directives include more than “do not treat” orders. They clarify what you want and what you don’t want. They apply if you sustain an injury, are ill, or otherwise unable to speak for yourself at any age.

Young adults may have the most at stake, since life-support technology could keep them alive for decades if they do not document their preferences.

Why End-of-Life Planning Documents Matter

Without a health care proxy or power of attorney in place, your family may face legal obstacles and emotional conflict during a crisis. Courts may need to appoint a guardian, or state law may assign decision-making power to someone you would not choose.

These delays and disputes often occur at the worst possible time. End-of-life documents relieve stress by giving your loved ones clear guidance. Instead of guessing what you would want, they can follow your written wishes with confidence.
