What Happens in Colorado If You Have No Medical Power of Attorney

Most people assume their spouse or adult children automatically become the medical decision-maker if something happens. In Colorado, it doesn't work that way. Without a Medical Durable Power of Attorney (MDPOA), the process for determining who decides about your care is more complicated, slower, and more prone to family conflict than most people realize.

Colorado's Proxy Decision-Maker Act

Colorado's unique approach to surrogate medical decision-making is codified in C.R.S. § 15-18.5-103. Unlike states with a simple statutory next-of-kin hierarchy (spouse first, then adult children, then parents), Colorado requires a consensus-based process among all "interested persons."

Here's what actually happens when you're incapacitated in a Colorado hospital without an MDPOA:

1. The attending physician determines you lack decision-making capacity
2. The physician must make reasonable efforts to contact all "interested persons"
3. These persons must reach unanimous consensus on a single proxy decision-maker
4. Only after consensus is reached can that proxy authorize or refuse treatment

Who Qualifies as an "Interested Person"

The statute casts a wide net. Interested persons include:

• Your spouse or civil union partner
• Either parent
• Any adult child
• Any adult sibling
• Any adult grandchild
• A close friend who is familiar with your values and medical preferences

All of these people get a voice. All must agree on who decides. If you have a spouse, three adult children, and both parents alive — that's potentially six people who must reach agreement before any treatment decision proceeds.

When Family Consensus Fails

This is where Colorado's system breaks down in practice. A single dissenting family member can block consensus. Common scenarios:

Estranged relatives. A sibling who hasn't spoken to the family in years technically remains an interested person. If the hospital can contact them, they get a vote. If they can't be reached, the hospital must document reasonable efforts to locate them before proceeding.

Second-marriage conflicts. A current spouse and adult children from a prior marriage may have fundamentally different views on treatment aggressiveness. Each has standing as an interested person, and neither automatically outranks the other.

Religious or philosophical disagreements. One family member believes in pursuing all possible treatment while another respects what they believe the patient would have wanted. Without a documented directive, both positions are legally valid.

Distance and availability. The consensus requirement means all interested persons ideally participate. When family members live in different states or time zones, coordination delays critical decisions.

The Guardianship Fallback

When interested persons cannot reach consensus, the family's only recourse is filing a petition in Colorado probate court for emergency guardianship. This involves:

• Filing a petition with the district court (filing fee: $229)
• A court investigation
• A hearing where the judge determines who should serve as guardian
• Appointment of a guardian with legal authority over medical decisions
• Potential appointment of a professional guardian (billing $150-$300/hour) if no family member is suitable

This process takes days to weeks — even with emergency procedures. Meanwhile, the patient receives default standard care, which may include aggressive life-sustaining interventions that the patient would not have wanted.

The Cost of No Planning

Beyond the emotional toll, the financial impact is real:

• Emergency guardianship attorney fees: $3,000-$10,000+
• Professional guardian fees: $150-$300/hour, ongoing
• Court filing and investigation costs: $500-$1,000+
• Extended ICU stays while decisions are delayed: thousands per day

Compare this to executing an MDPOA while competent: zero filing fees, no court involvement, immediate effect, and your chosen person has clear authority without needing anyone else's agreement.

How the MDPOA Prevents All of This

A Medical Durable Power of Attorney short-circuits the entire consensus process. When you have a valid MDPOA:

• Your named agent has exclusive decision-making authority
• No consensus among family members is required
• No court involvement is needed
• The agent can act immediately upon your incapacity (if standing) or upon physician certification (if springing)
• Other family members' objections have no legal weight

This is why the MDPOA is arguably the single most important advance directive document in Colorado — more impactful than even the Living Will in terms of preventing family chaos during medical crises.

The Emergency Exception

Colorado law does permit physicians to provide emergency treatment without consent when a patient is incapacitated and no authorized decision-maker is available. But this covers only immediate life-saving interventions — not ongoing treatment decisions, care setting choices, or end-of-life preferences. Once the immediate emergency stabilizes, the consensus process or guardianship petition must still occur for continued decision-making.

The Colorado Advance Directive & Living Will Kit includes the MDPOA with both standing and springing options, alternate agent designations, and guidance on choosing someone who will advocate effectively without needing family consensus.
