Glossary: Healthcare Power of Attorney

A healthcare power of attorney is a legal document that allows you to appoint someone to make medical decisions on your behalf if you are unable to do so.

This person (often called a healthcare proxy or agent) is authorized to speak with medical professionals, consent to or refuse treatments, and act based on your values and preferences.

What a healthcare power of attorney does

A healthcare power of attorney provides decision-making authority for medical situations.

It allows your appointed person to:

• communicate with doctors and healthcare providers
• make treatment decisions on your behalf
• interpret your wishes in complex or unexpected situations
• act when you are unable to communicate

Why you need a healthcare power of attorney

A healthcare power of attorney ensures that someone you trust can actively represent your interests.

Without one:

• decisions may be made according to default legal rules
• family members may disagree or lack authority
• your preferences may not be clearly represented

With one:

• a trusted person can act on your behalf
• decisions are more aligned with your values
• uncertainty is reduced in critical situations

How a healthcare power of attorney works

A healthcare power of attorney:

• becomes effective when you are unable to make decisions
• gives authority to a designated individual (your agent)
• works alongside other documents like a living will

It provides flexibility because your agent can respond to situations not explicitly covered in written instructions.

What a healthcare power of attorney does NOT do

A healthcare power of attorney does not:

• apply while you are able to make your own decisions
• cover financial or legal matters
• replace a living will or other medical directives

It grants authority, not predefined instructions.

When you need a healthcare power of attorney

You should consider a healthcare power of attorney if:

• you want someone to actively represent your medical interests
• you want flexibility in decision-making
• you want to avoid uncertainty or delays in care

It is relevant for adults at any stage of life.

Common misunderstandings

Some common misconceptions include:

• thinking family members automatically have authority
• confusing it with a living will
• assuming it covers financial decisions

Clear documentation and communication are essential.
