Why This Paperwork Matters Before a Crisis
The single most common obstacle Phoenix senior care advisors encounter when helping a family navigate an urgent placement or ALTCS application is missing legal authority. An adult child who has been informally managing a parent's affairs for years discovers — in the middle of a hospital discharge — that they have no legal standing to sign contracts, access financial records, or make healthcare decisions.
Arizona has its own statutory framework for advance directives and powers of attorney that differs from other states in important ways. This guide covers what Arizona requires, what each document does, and why doing this before a care crisis is enormously better than doing it after.
Durable Financial Power of Attorney
An Arizona Durable Financial POA authorizes the named agent to manage the principal's financial affairs — bank accounts, real estate, investments, tax filings, and bill payment. 'Durable' means the document remains in effect if the principal becomes incapacitated.
Arizona's statutory form is codified at A.R.S. § 14-5501. For it to be effective, it must be signed by the principal while they have legal capacity to grant authority. A principal who has already lost capacity cannot grant a POA — the family's only legal option at that point is adult guardianship or conservatorship, which requires court involvement and is significantly more expensive and time-consuming.
For ALTCS applications, AHCCCS requires an authorized representative — typically someone with durable POA — to submit and manage the application on behalf of an incapacitated applicant.
Healthcare POA and Living Will
Arizona's Healthcare Power of Attorney (HCPOA) authorizes the named agent to make medical decisions when the principal is unable to do so. It does not activate until the principal lacks capacity to make their own decisions.
Arizona's living will allows the principal to specify end-of-life care wishes — including mechanical ventilation, artificial nutrition, CPR, and other interventions in the event of a terminal condition. These documents are governed by A.R.S. § 36-3221.
The HCPOA and living will work together: the HCPOA names who speaks for the patient, and the living will specifies what they should say. Both should be discussed with the named agent — a person who discovers they have healthcare POA authority for the first time in an ICU waiting room is not in the best position to act on it confidently.
POLST: The Clinical Order That Travels with Your Parent
A POLST (Physician Orders for Life-Sustaining Treatment) is a physician order set that translates the patient's wishes into specific clinical instructions traveling across care settings. In Arizona, it is the Arizona Medical Orders for Scope of Treatment (MOST) form.
The MOST form specifies orders for CPR, level of medical intervention, and artificial nutrition. It is signed by a physician or NP and accompanies the patient from hospital to SNF to ALF. Emergency responders can and do follow a MOST form — they cannot follow a living will in the field.
