Healthcare Proxy vs Power of Attorney: Which One Covers What?

Your mother is in the ICU after a stroke. The hospital needs someone to authorize a procedure. Your brother has financial power of attorney. He calls the hospital and says he's in charge — but the doctors tell him his POA doesn't cover medical decisions. Meanwhile, nobody signed a healthcare proxy.

This is the gap that traps thousands of families every year. The two documents sound similar but cover completely different territory.

What a Healthcare Proxy Does

A healthcare proxy (called medical power of attorney in some states) appoints a specific person to make medical decisions when your parent can't speak for themselves. That proxy — sometimes called a healthcare agent or surrogate — can:

• Consent to or refuse medical treatments
• Choose between care facilities
• Authorize or decline surgical procedures
• Make decisions about life-sustaining treatment
• Access medical records (when paired with HIPAA authorization)

A healthcare proxy only activates when a physician determines your parent lacks decision-making capacity. Until that point, your parent makes their own medical choices.

What a Financial Power of Attorney Does

A financial POA appoints someone to manage your parent's money and legal affairs. That agent can:

• Access and manage bank accounts
• Pay bills, mortgages, and insurance premiums
• File tax returns
• Buy or sell real estate
• Manage investment accounts
• Apply for government benefits

A durable financial POA stays in effect even after your parent becomes incapacitated. It covers everything about money — and nothing about medicine.

The Gap Between Them

The confusion comes because both documents are called "power of attorney." But they operate in completely separate legal domains. A financial POA gives zero medical authority. A healthcare proxy gives zero financial authority.

Families commonly discover this gap at the worst moment:

• Your parent is hospitalized, and the child with financial POA can't approve treatment
• Your parent needs to move to a nursing home, and the child with the healthcare proxy can't access the bank accounts to pay the deposit
• Your parent has dementia, and one sibling has medical authority while another has financial authority, and they disagree on the level of care

Why You Need Both — Named to the Same Person

The simplest approach: appoint the same trusted person as both financial agent and healthcare proxy, with the same alternate/successor agents for both. This prevents coordination problems and ensures one person can handle an emergency from both the medical and financial side.

If you split the roles between different family members — say, one sibling handles finances and another handles medical decisions — document this clearly and ensure both agents communicate regularly. This arrangement works well when one sibling has financial expertise and another lives near the parent and knows their medical providers, but it requires explicit coordination protocols.

The HIPAA Piece Most Families Miss

Even with a healthcare proxy, doctors may refuse to share detailed medical information with family members unless a separate HIPAA authorization is on file. This isn't a technicality — it's a real barrier.

File a HIPAA release with every provider: primary care, specialists, pharmacies, hospitals, and any home health agency. Some authorizations expire (SSA medical records expire in 90 days), so track renewal dates.

How to Get Both Documents Done

1. Find an elder law attorney — a standard estate planning package ($1,500 to $3,500 for an individual) typically includes a durable financial POA, healthcare proxy, advance directive, and basic will
2. Execute them at the same time — there's no reason to do one without the other
3. Follow your state's formalities — witness and notarization requirements vary
4. Distribute copies — healthcare proxy goes to the named agent, all siblings, the parent's primary care physician, and the local hospital. Financial POA goes to the agent, all financial institutions, and the attorney.
5. Don't wait — both documents require your parent to be mentally competent when they sign

The Organizing a Parent's Important Documents toolkit tracks both documents together — including which institutions have copies, when HIPAA authorizations need renewal, and a review schedule to keep everything current.
