Medical Power of Attorney Tennessee: How to Appoint a Healthcare Agent

When a Tennessee resident loses the ability to make medical decisions — whether from a stroke, surgical complication, or progressive illness — someone else has to step in. Without a designated healthcare agent, that decision falls to a state-defined hierarchy that may not reflect what the patient actually wants.

Tennessee doesn't use a standalone "medical power of attorney" form. Instead, the healthcare agent appointment is built into the state's unified Advance Directive for Health Care, governed by the Health Care Decisions Act (T.C.A. §§ 68-11-1801 et seq.).

How the Healthcare Agent Appointment Works

Part 1 of the Tennessee advance directive lets you name a primary healthcare agent and at least one alternate. Your agent gains authority to make medical decisions only when your supervising physician determines you lack decision-making capacity — not before.

Your agent's powers include:

• Consenting to or refusing any medical treatment, procedure, or surgery
• Requesting or approving the withdrawal of life-sustaining treatments
• Accessing your medical records under HIPAA authorization
• Making decisions about facility transfers, discharge, and care settings

You can limit your agent's authority in the "Individual Instructions" section. For example, you might grant full authority for treatment decisions but exclude the power to authorize organ donation or specify that certain treatments must always be provided.

Who Can and Cannot Serve as Your Agent

Tennessee law doesn't restrict who you can appoint as your healthcare agent, but practical considerations matter. Your agent should be someone who understands your values, can handle high-pressure medical conversations, and is geographically accessible enough to respond quickly during emergencies.

The witness rules create the main restrictions. Under T.C.A. § 68-11-1803(b), your designated healthcare agent cannot serve as a witness to your advance directive. At least one of your two witnesses must be unrelated to you by blood, marriage, or adoption, and at least one must have no claim to your estate.

The Default Surrogate Hierarchy

If you haven't named a healthcare agent and lose capacity, T.C.A. § 68-11-1806 establishes the order in which your supervising physician selects a default surrogate:

1. Spouse (unless legally separated)
2. Adult child
3. Parent
4. Adult sibling
5. Any other adult relative
6. An adult who has shown special care and concern for you

When multiple people share the same priority level — say, three adult children — and they disagree, the facility cannot resolve the conflict. A family member would need to petition the county court to appoint a Conservator of the Person, which means attorney involvement, court hearings, and significant expense during an already difficult time.

A default surrogate who was not personally chosen by the patient also faces a hard legal limit: they cannot authorize withholding or withdrawing artificial nutrition and hydration unless two physicians certify in writing that continuing would merely prolong active dying with no reasonable chance of recovery.

Why "Durable" Matters

Tennessee's healthcare agent designation is durable by default — it survives your incapacity. A standard power of attorney (the kind used for financial transactions) terminates when the principal loses capacity unless it's explicitly made durable. With an advance directive healthcare agent, durability is built in. That's the entire point: the authority activates precisely when you can no longer decide for yourself.

Steps to Appoint Your Healthcare Agent

1. Choose your primary agent and at least one alternate — discuss your wishes with them before signing
2. Complete Part 1 of the Tennessee Advance Directive for Health Care form
3. Add any limitations or special instructions in the Individual Instructions section
4. Execute the document with a notary or two qualified witnesses
5. Distribute copies to your agent, alternate, primary care doctor, and any regular treatment facilities

Your agent's authority takes effect across all licensed healthcare facilities in Tennessee. The directive is portable — it travels with you between hospitals, nursing homes, and home care settings.

The Tennessee Advance Directive & Living Will Kit includes a healthcare agent discussion guide with specific conversation prompts, a witness verification protocol, and instructions for coordinating your agent appointment with a POST form for emergency situations.
