Health Care Power of Attorney Tennessee: Appointing a Medical Decision-Maker for Your Parent

Tennessee Doesn't Have a Standalone Medical Power of Attorney

If you're searching for a Tennessee medical power of attorney form, you won't find one as a separate document. Since the Tennessee Health Care Decisions Act took effect, the state consolidated the medical POA and living will into a single Advance Directive for Health Care (T.C.A. § 68-11-1801 et seq.).

Part 1 of that advance directive is where your parent appoints a health care agent — the person who makes medical decisions when your parent cannot. That appointment is what other states call a "medical power of attorney" or "health care proxy."

This distinction matters practically, not just legally. If you present a hospital's patient services office with a document titled "Medical Power of Attorney" that doesn't follow Tennessee's statutory framework, the facility may refuse to recognize it.

What a Tennessee Health Care Agent Can and Cannot Do

The health care agent's authority activates when the supervising physician determines your parent lacks the capacity to make their own medical decisions. Until that clinical finding, your parent retains full control.

Once activated, the agent can:

• Consent to or refuse medical treatment, surgery, and diagnostic procedures
• Authorize or withdraw life-sustaining treatment per the parent's documented wishes
• Access medical records protected under HIPAA
• Choose or change health care providers and facilities
• Make decisions about organ and tissue donation

The agent cannot override specific treatment instructions your parent documented in Part 2 of the advance directive. If your parent wrote that they do not want mechanical ventilation under any circumstances, the agent must honor that directive even if they personally disagree.

The agent also has no financial authority whatsoever. They cannot access bank accounts, pay medical bills, negotiate with insurance companies, or sign facility admission contracts that involve financial guarantees. Those powers require a separate Durable Financial Power of Attorney under T.C.A. § 34-6-102.

Who Can Serve as Health Care Agent

Tennessee law allows any competent adult to serve as health care agent. There are two restrictions worth knowing:

The attending physician cannot serve. The physician responsible for the parent's care cannot simultaneously act as their health care agent — the dual role creates an obvious conflict of interest.

No professional licensing requirement. The agent does not need to be a lawyer, nurse, or medical professional. Most families appoint an adult child, spouse, or trusted friend who knows the parent's values and can advocate firmly in clinical settings.

Your parent should name at least one successor agent. If the primary agent is unavailable during a medical emergency — traveling, incapacitated themselves, or unable to be reached — the successor steps in without needing a new document or court order.

Execution Requirements That Trip Families Up

The advance directive must be either notarized or witnessed by two competent adults. If using witnesses:

• At least one witness must be an independent individual who is not related to the principal by blood, marriage, or adoption and is not entitled to any portion of the principal's estate under an existing will or by operation of intestate law
• Neither witness can be the person being appointed as health care agent
• Both witnesses must be present when the parent signs

The parent must have decision-making capacity at the moment of signing. A dementia diagnosis alone doesn't disqualify them — the legal standard asks whether they understand what the document does, who they're appointing, and what authority they're granting. If there's any doubt, having the parent's physician document their capacity assessment on the same day provides a layer of protection against future challenges.

The Fallback When No Health Care Agent Exists

If your parent becomes incapacitated without an advance directive, Tennessee's statutory surrogate hierarchy applies (T.C.A. § 68-11-1806). The supervising health care provider may identify a surrogate from this priority list:

1. Spouse (unless legally separated)
2. Adult children
3. Parents
4. Adult siblings
5. Other adult relatives who have shown special concern

If potential surrogates of equal rank conflict, or if no family members are available, the supervising health care provider may designate an independent surrogate, or the facility may pursue emergency court intervention.

An advance directive eliminates that ambiguity by putting one named person in charge from the start.

Getting Both Documents Done Together

Most Tennessee families need two documents working in parallel: the advance directive for medical decisions and the durable financial POA for everything financial. Executing both in the same session — while your parent has capacity — is the single most effective step you can take to avoid a conservatorship later.

The Tennessee Power of Attorney & Guardianship Kit covers both documents with Tennessee-specific execution checklists, including the witness and notarization rules that vary from what you'll find in generic national templates.
