Medical Power of Attorney in Georgia: What It Is and How It Works

Most people focus their estate planning attention on what happens to their property after they die. Far fewer give comparable attention to what happens to their person before death — during the period of incapacity that a serious illness, injury, or cognitive decline may produce. The medical power of attorney is the document that fills that gap, designating a trusted person to make healthcare decisions when the patient no longer can.

What a Medical Power of Attorney Is

A medical power of attorney — also called a healthcare power of attorney or, in Georgia's current legal framework, the healthcare agent designation — is a legal document that authorizes a named individual to make medical decisions on the principal's behalf when the principal lacks the capacity to make or communicate those decisions independently.

The person granted this authority is called the healthcare agent, healthcare proxy, or surrogate. Their role is to step into the principal's shoes for medical decision-making: consulting with doctors, reviewing treatment options, consenting to or refusing procedures, directing the course of care, and advocating for the principal's values and expressed preferences.

How Georgia Handles the Medical POA Today

Before July 1, 2007, Georgia residents who wanted to designate a healthcare decision-maker executed a standalone Durable Power of Attorney for Health Care — a document separate from a living will. The Georgia General Assembly eliminated that structure in 2007, replacing it with the Georgia Advance Directive for Health Care, which combines the agent designation function and the treatment preference function into a single document.

The term "medical power of attorney" remains commonly used to describe the healthcare agent designation component of the Advance Directive — the part that names who will make decisions — as distinguished from the living will component, which specifies what decisions should be made under particular circumstances. In practice, when Georgians or their attorneys refer to a medical power of attorney in Georgia today, they are referring to the healthcare agent section of the Advance Directive.

The practical takeaway: anyone in Georgia who wants to designate a healthcare agent executes the Georgia Advance Directive for Health Care, not a separate standalone medical POA form.

What the Healthcare Agent Is Authorized to Do

The healthcare agent's authority is broad when properly executed. Subject to any limitations the principal specifies in the document, the agent can consent to or refuse any medical treatment — including surgery, hospitalization, medication, artificial hydration and nutrition, ventilator support, and resuscitation. The agent can access the principal's medical records, communicate with all healthcare providers, make decisions about care settings and facilities, and direct the course of treatment in real time as conditions evolve.

Critically, the agent's authority is guided by the instructions the principal provides in the document and by the principal's known values and wishes. The agent is not free to make decisions based on their own preferences — they are obligated to act in accordance with what the principal would want, or, where those wishes are unknown, in the principal's best interest.

The agent's authority also includes decisions after death: the principal can authorize the agent to consent to an autopsy, to make decisions about organ donation, and to direct the disposition of the remains.

Who Cannot Serve as Agent

Georgia law places limits on who may serve as healthcare agent to protect principals from potential exploitation. The principal's treating physician and other healthcare providers directly involved in the principal's care cannot serve as agent. An operator or employee of a healthcare facility where the principal is a patient cannot serve — with limited exceptions. These restrictions exist because people in those positions have inherent conflicts of interest that could compromise their ability to act solely in the principal's interest.

The principal's attorney-in-fact under a financial power of attorney can serve as healthcare agent, but only if they are also designated in the healthcare document — the financial power of attorney does not extend to medical decision-making automatically.

Execution Requirements

For a Georgia healthcare agent designation to be legally valid, the principal must be at least 18 years old and of sound mind at the time of execution. The document must be signed by the principal in the presence of two witnesses. The witnesses must also sign the document, and they cannot be the designated agent, anyone who would inherit from the principal's estate, or anyone directly involved in the principal's healthcare. A notary is not required under Georgia law, though some families choose to have the document notarized for additional formality.

When the Agent's Authority Activates

The healthcare agent has no authority while the principal retains decision-making capacity. As long as the principal can make and communicate their own healthcare choices — even choices others might disagree with — those choices govern. The agent steps in only when the principal's physician determines that the principal lacks sufficient capacity to make or communicate healthcare decisions. This determination is made in the clinical context and is typically documented in the medical record.

The Difference Between the Medical POA and Financial POA

A common source of confusion is assuming that a financial power of attorney covers medical decisions, or vice versa. It does not. Georgia law treats these as entirely separate grants of authority. A financial power of attorney authorizes an agent to manage financial and legal matters — bank accounts, investments, contracts, real estate transactions, tax filings. It has no effect on healthcare decisions. A healthcare agent designation under the Advance Directive authorizes medical decision-making and nothing more.

A complete incapacity plan addresses both: a durable financial power of attorney and a Georgia Advance Directive for Health Care with a designated healthcare agent. Without both documents, a different mechanism — usually a court-supervised guardianship or conservatorship proceeding — becomes necessary to authorize someone to manage the incapacitated person's affairs.

Why It Belongs in Every Adult's Estate Plan

The need for a healthcare agent designation is not limited to the elderly or seriously ill. A healthy 30-year-old in a car accident, a 50-year-old under general anesthesia for a routine surgery, or a 65-year-old in the early stages of cognitive decline all face situations where medical decisions may need to be made on their behalf. Without a valid designation, the law provides no automatic mechanism — family members have no legal authority to direct medical care simply by virtue of their relationship, and hospitals may default to their own protocols or seek court-appointed guardianship.
