Illinois Health Care Surrogate Act: Who Decides When There Is No POA

Your father is unconscious in the ICU after a stroke. He never signed a healthcare power of attorney. Three of his adult children are standing at the bedside, and two of them disagree about whether to authorize a risky surgical procedure. The hospital's patient advocate arrives and explains that Illinois law has a specific hierarchy for exactly this situation — and the decision does not belong to all three children equally.

The Illinois Health Care Surrogate Act (755 ILCS 40) is the state's default system for medical decision-making when a patient has not appointed a healthcare agent. It designates who speaks for the patient when no advance directive exists, and its priority order surprises many families.

The Statutory Priority List

When an attending physician determines that a patient lacks decision-making capacity and no healthcare power of attorney is on file, the Surrogate Act activates automatically. The law assigns decision-making authority in this specific order:

  1. Guardian of the person — if one has been appointed by the court
  2. Spouse
  3. Adult children — any adult son or daughter of the patient
  4. Parents
  5. Adult siblings
  6. Adult grandchildren
  7. Close friend — someone who has maintained regular contact and is familiar with the patient's activities, health, and beliefs
  8. Guardian of the estate — if one exists but there is no guardian of the person

The highest-ranking available person on this list becomes the surrogate decision-maker. If multiple people share the same priority level (for example, three adult children), they are supposed to reach consensus. If they cannot agree, the healthcare team faces a conflict that may require ethics committee involvement or, in extreme cases, a court petition for guardianship.

What the Surrogate Can and Cannot Do

A surrogate designated under this Act does not have the same broad authority as an agent appointed under a healthcare power of attorney. Key limitations:

Treatment decisions only. The surrogate can consent to or refuse medical treatment on the patient's behalf. They cannot make financial decisions, access bank accounts, sell property, or handle any matter outside of healthcare.

Must follow patient's known wishes. If the patient expressed specific preferences about treatment while competent — even informally in conversations with family — the surrogate is legally obligated to follow those expressed wishes rather than substituting their own judgment.

Best interest standard. When the patient's wishes are unknown, the surrogate must act in the patient's best interest, considering the patient's personal values, the benefits and burdens of treatment, and the patient's dignity.

Withdrawal of life-sustaining treatment. A surrogate can authorize withdrawal of life-sustaining treatment, but the attending physician must confirm that the patient lacks decision-making capacity and that the condition meets specific criteria (terminal illness, permanent unconsciousness, or incurable condition where treatment would impose burdens that outweigh benefits).

Why the Surrogate Act Is a Poor Substitute for a Healthcare POA

The Surrogate Act exists as a safety net, not a planning tool. It has several structural problems that a healthcare power of attorney eliminates:

You do not choose your decision-maker. The priority list is fixed by statute. If your relationship with your spouse is strained, or if one of your adult children is better suited to handle medical crises than the others, the Surrogate Act does not allow you to make that distinction. The statutory order applies regardless of personal dynamics.

Family conflict is common. When multiple people share the same priority level, disagreements can paralyze decision-making at the worst possible time. Two adult children who have different views about aggressive treatment can create a deadlock that leaves the medical team unable to act. A healthcare POA eliminates this by naming one person as the primary decision-maker with clear authority.

No post-death authority. A surrogate under the Act does not automatically have authority over post-death decisions like organ donation, autopsy, or disposition of remains. An agent under a healthcare POA can be granted these powers explicitly.

No HIPAA access guarantee. While the Surrogate Act gives the surrogate access to medical information needed for treatment decisions, the scope is narrower than the HIPAA personal representative designation built into the statutory healthcare POA form. Institutions occasionally resist sharing records with surrogates, creating delays during time-sensitive decisions.

Court intervention risk. If the surrogate's decisions are disputed by other family members, or if no one on the priority list is available, the only recourse is a court petition for guardianship — a process that costs thousands of dollars, takes weeks to months, and creates a permanent public court record.

The Dementia Planning Gap

The Surrogate Act is particularly inadequate for patients with progressive cognitive decline. A person with early-stage Alzheimer's may be competent to sign a healthcare POA today but will lose that capacity within months or years. If they wait until the diagnosis progresses, the window closes — and the Surrogate Act becomes the default.

The problem is that a surrogate who was never explicitly chosen by the patient may not know the patient's specific wishes about feeding tubes, ventilator support, comfort care, or whether to pursue aggressive treatment for secondary infections. Families are left guessing, and that guessing frequently leads to guilt, conflict, and decisions that may not reflect what the patient wanted.

How to Avoid the Surrogate Act

The entire purpose of executing a healthcare power of attorney is to bypass the Surrogate Act's default hierarchy. When you sign a valid healthcare POA:

  • You choose exactly who makes your medical decisions
  • You can name successor agents if your primary choice is unavailable
  • You can specify the scope of authority (including post-death decisions)
  • You eliminate the risk of family conflict over who has priority
  • You provide HIPAA authorization for your agent to access your records immediately

The Illinois Advance Directive & Living Will Kit includes an agent screening worksheet that walks you through selecting the right healthcare agent — covering emotional resilience, geographic proximity, and willingness to carry out difficult decisions — so you never have to rely on the statutory default.
