Healthcare Power of Attorney vs. Living Will: Key Differences and When You Need Both

When planning for your future healthcare needs, two important documents to consider are the healthcare power of attorney (HCPA) and the living will. These documents help make sure your medical preferences are followed in case you're unable to communicate or make decisions for yourself.

At Porter Law Firm in Mount Pleasant and Hilton Head, South Carolina we can help you with the key differences between a healthcare power of attorney and a living will, how each document functions, and why it's often wise to have both in place as part of your estate plan.

What Is a Healthcare Power of Attorney?

A healthcare power of attorney (HCPA) is a legal document that appoints someone (known as your agent or proxy) to make medical decisions on your behalf if you're unable to do so. This document provides a trusted individual with the authority to make decisions regarding your medical care when you’re incapacitated or otherwise unable to communicate your preferences.

The person you appoint as your agent should be someone you trust deeply — someone who understands your values and can act in your best interest in various medical situations. You can outline specific preferences in the healthcare power of attorney, or you can leave decisions up to your agent. Key elements of a healthcare power of attorney include:

  • Appointment of an agent: You choose the person responsible for making medical decisions for you.

  • Scope of authority: You can decide how much authority you want to give your agent — whether it’s broad or limited to specific medical decisions.

  • Activation: This document typically takes effect when a physician determines that you’re unable to make your own healthcare decisions.

  • Flexibility: Your healthcare power of attorney can be revoked or modified as needed, giving you control over the document.

It’s important to note that a healthcare power of attorney only covers medical decisions and doesn’t extend to other aspects of your life, such as finances or legal matters. For those, other documents, like a durable power of attorney, would be needed.

What Is a Living Will?

A living will is a legal document that allows you to specify your wishes regarding medical treatment if you’re terminally ill or permanently unconscious. It’s used to guide healthcare providers and loved ones when decisions about life-sustaining treatments are necessary, and you’re unable to communicate your preferences.

The living will can include detailed instructions for specific scenarios, such as:

  • End-of-life care: Whether you wish to receive life-sustaining treatments, like a ventilator or feeding tube, in the event of terminal illness.

  • Organ donation: Whether or not you wish to donate organs or tissues after death.

  • Palliative care: Instructions about pain management or comfort care if you're in a terminal state.

By having a living will, you can make sure that your healthcare providers and loved ones know exactly how you want to be treated in critical situations. However, this document doesn’t appoint anyone to make decisions for you, and it doesn’t address situations where you may need temporary medical care, such as recovery from surgery or injury.

Key Differences Between Healthcare Power of Attorney and Living Will

While both the healthcare power of attorney and living will help make sure that your medical wishes are respected, they serve different purposes. It’s important to understand how each document works in order to make informed decisions about your estate planning. Here are the key differences:

  • Who makes decisions?

    • Healthcare power of attorney: Appoints an agent to make medical decisions on your behalf.

    • Living will: Provides written instructions for your healthcare providers but doesn’t appoint anyone to make decisions for you.

  • Scope of decisions:

    • Healthcare power of attorney: Covers a broad range of medical decisions, from routine care to critical life decisions.

    • Living will: Focuses on specific medical situations, such as end-of-life care or life support.

  • Activation:

    • Healthcare power of attorney: Takes effect when a doctor determines you're unable to make decisions.

    • Living will: Only becomes relevant in specific situations, such as terminal illness or irreversible coma.

  • Duration:

    • Healthcare power of attorney: Remains in effect until you revoke it or pass away.

    • Living will: Only applies to situations involving life-sustaining treatments or organ donation.

The differences between the healthcare power of attorney and living will highlight the complementary nature of these two documents. While a living will helps clarify your wishes in specific situations, the healthcare power of attorney gives someone the authority to make broader medical decisions for you.

Why You Need Both Documents

You may be wondering why it's necessary to have both a healthcare power of attorney and a living will in place. While they serve different functions, these documents work together to create a comprehensive healthcare plan. Here’s why both are important:

  • Comprehensive coverage: The healthcare power of attorney and living will fill in different gaps. The living will makes sure your preferences are known for specific life-or-death scenarios, while the healthcare power of attorney gives your agent the flexibility to make decisions in a wide range of situations.

  • Clarity for loved ones: Having both documents in place makes things easier for your loved ones when tough decisions arise. They’ll know your wishes ahead of time, which can reduce the burden of making difficult choices in uncertain circumstances.

  • Preventing conflicts: In some cases, family members may disagree about your medical care. A healthcare power of attorney gives one person the authority to make decisions, potentially preventing disputes among family members. Meanwhile, the living will provides clear instructions for critical situations.

Together, these documents help make sure your healthcare preferences are followed, whether you're facing a temporary illness or a life-threatening condition. Both are crucial tools for anyone looking to plan ahead and protect their healthcare rights.

When to Update Your Healthcare Power of Attorney and Living Will

Your healthcare power of attorney and living will are not “set it and forget it” documents. Life changes, and so might your medical preferences. Regularly reviewing and updating your documents allows them to reflect your current wishes. You should update your healthcare power of attorney and living will in the following situations:

  • Significant life changes: If you move to another state, get married, or go through a divorce, it’s a good idea to review your documents to make sure they still reflect your wishes.

  • Changes in health: If your health status changes, such as being diagnosed with a serious illness or developing a condition that requires ongoing medical care, update your documents to reflect these changes.

  • Change of agent: If the person you've appointed as your agent for healthcare decisions is no longer able or willing to act in that role, choose a new agent and update the document.

  • Review every few years: Even if nothing has changed in your life, it’s a good practice to review these documents every few years to make sure they’re still in line with your wishes.

By regularly reviewing and updating your healthcare power of attorney and living will, you help make sure that your healthcare decisions are as clear and accurate as possible.
