Does Medical Power of Attorney Cover Mental Health in Arizona?

It's a good idea to plan ahead for healthcare decisions, including the chance that you won't be able to make them on your own. A Medical Power of Attorney (MPOA) is a very significant legal paper. But in Arizona, this agreement doesn't cover everything. A lot of people ask Mozell Law Group if a medical power of attorney in Arizona includes mental health treatments.
The short answer: No, not entirely. Arizona law treats mental health care as a separate category, requiring its own legal documentation. The next part goes into more detail on the differences, requirements, and tactics that are necessary to make sure that Arizona law protects you properly.
What Is a Medical Power of Attorney in Arizona?
A Medical Power of Attorney (MPOA) lets you choose someone else (your agent) to make medical decisions for you if you can't do it yourself. This includes decisions about medications, surgeries, long-term care, and other needs for physical health. It also includes the authority to make all mental health treatment decisions, except for one: admission to a psychiatric hosp
ital.
In Arizona, MPOAs must:
Be signed by you while you are of sound mind
Be witnessed by an adult or notarized
Your agent has a lot of power over your general healthcare with an MPOA. However, unless you include specific language or sign a separate Mental Health Power of Attorney (MHPOA), your agent does not automatically have the power to make decisions about mental health treatment.
What Is a Mental Health Power of Attorney in Arizona?
If you are found to be unable to make informed decisions, a Mental Health Power of Attorney (MHPOA) is a legal document that names someone you trust to make decisions about your mental health care.
Key Features of a MHPOA:
Covers psychiatric evaluation and treatment decisions inside a psychiatric hospital
Authorizes placement in a mental health treatment facility if necessary
Grants consent to or refusal of specific psychiatric medications
May include a Mental Health Care Declaration stating your preferences
Just like a MPOA, a MHPOA must be:
Executed while the individual is competent
Signed in the presence of a witness or a notary public
Does a Medical Power of Attorney Cover Mental Health in Arizona?
Technically: Not without specific language or a separate MHPOA.
In Arizona, the law requires a Mental Health Power of Attorney if you want your agent to make decisions related to inpatient psychiatric care. A general MPOA will not suffice unless it specifically addresses mental health authority, which most do not.
If you lose your mental capacity and only have a medical power of attorney, your loved ones may have to go to court to get you the care you need (for example, guardianship or emergency mental health orders).
How to Ensure Full Healthcare Coverage in Arizona
To make sure your healthcare wishes are honored in any situation, including a mental health crisis, we recommend the following steps:
1. Draft Both an MPOA and MHPOA
Work with an experienced Arizona estate planning or mental health attorney to create both documents. Each serves a distinct purpose and protects you in different ways.
2. Be Clear About Your Wishes
Include any specific preferences for mental health care in a Mental Health Care Declaration. This might cover:
Preferred treatment facilities
Medications you consent to or refuse
Preferences regarding restraint or seclusion
3. Choose a Trusted Agent
The person you name as your healthcare or mental health agent should be someone you trust deeply to follow your instructions and act in your best interest.
4. Notify Key People
Provide copies of your MPOA and MHPOA to:
Your designated agents
Primary care and mental health providers
Close family members or caregivers
5. Review Periodically
Laws, circumstances, and relationships can change. Review your healthcare documents every few years, or after any major life event.
What Happens If You Don’t Have a Mental Health Power of Attorney?
Without a MHPOA, your loved ones may be required to:
Seek a court-appointed guardian
File for involuntary treatment under Arizona's Title 36 mental health statutes
Navigate emergency petitions, hearings, and potentially drawn-out legal proceedings
These processes can be emotionally and financially taxing. Having the proper documents in place helps prevent unnecessary court involvement and ensures your care aligns with your personal values.
