Most people choose a healthcare agent and assume the document alone is enough. But don’t overlook what your healthcare agent needs to know before an emergency. It isn’t. If you’re ever in a crisis and can’t speak for yourself, your agent needs clear guidance—fast. That’s the difference between confident decisions and painful guessing.

This is a simple, practical guide to what your agent should know so your estate planning and incapacity planning actually work when your family needs them.
What a Medical Power of Attorney Does
A medical power of attorney (also called a healthcare power of attorney) lets you appoint someone to make healthcare decisions for you if you become seriously ill, injured, or incapacitated. Your agent’s job is to follow your wishes—based on what you’ve communicated—so your care reflects your values and priorities.
In most states, your healthcare provider can’t serve as your agent, but you can choose any other mentally competent adult you trust. The document must be signed with the required formalities (witnesses and/or notarization depending on the state).
The Conversation That Makes the Document Real
Once you name an agent, have a direct conversation with them. Better yet, give them a written “cheat sheet” they can pull up in an emergency.
Here’s what to include:
Preferred doctors and providers
Give names, phone numbers, and addresses for your primary physician and key specialists. If there are providers you do not want involved in your care, list that clearly.
Hospital and clinic preferences
Share where you prefer to receive care—and where you don’t. If a facility is a “hard no,” say so.
Current medical conditions
List diagnoses and any conditions that could affect treatment decisions. If you have a condition that could be misunderstood (for example, symptoms that mimic psychiatric issues), tell your agent what you want ruled out first.
Treatment and medical history
Document major procedures and surgeries, along with approximate dates. Even “old” history can matter in an ER.
Medication list
Keep an up-to-date list of your medications. If there are specific drugs you want refused, put that in writing.
Allergies and reactions
Be specific. Include medications, foods, environmental allergies, and any known adverse reactions. This helps your agent prevent serious errors when you can’t advocate for yourself.
Quality-of-life priorities
This is the heart of the plan. Tell your agent what matters most to you:
- Do you prioritize comfort or aggressive treatment?
- How do you feel about life-prolonging interventions like ventilators or feeding tubes?
- What outcomes would you consider acceptable or unacceptable?
Concrete examples help your agent make decisions that truly match your values.
Spiritual or religious beliefs
If faith shapes your healthcare choices, say so. Tell your agent if you want a chaplain involved, specific rites observed, or particular treatment limits based on beliefs.
Name a Backup Agent
Emergencies don’t wait for schedules. Name at least one successor (backup) agent so someone you trust can step in if your primary agent is unreachable or unable to serve.
Keep It Current
Review your medical power of attorney about once a year and after major life changes (moves, divorce, new diagnosis, changed relationships). Update the document if needed—and update the guidance you give your agent.
