Default Medical Decision Maker Oregon: Who Decides If You Don't Have an Advance Directive

If you're incapacitated in an Oregon hospital without a valid advance directive, you don't get to choose who makes your medical decisions. The state does — through a statutory surrogate hierarchy under ORS 127.635 that assigns decision-making authority in a fixed priority order.

For some families, this hierarchy works fine. For others, it creates delays, conflicts, and outcomes nobody wanted.

The Priority Order Under ORS 127.635

When an adult loses decision-making capacity without a designated Health Care Representative, the attending physician must make a reasonable effort to locate a surrogate in this order:

The attending physician works down the list until they find someone available and willing to serve. If a higher-priority category exists but can't be reached with reasonable effort, the physician moves to the next level.

Where This Hierarchy Breaks Down

Majority-Vote Deadlocks

At Priority 4 (adult children) and Priority 6 (adult siblings), Oregon requires a majority of all locatable individuals to agree. This creates problems when:

• Three adult children are divided 2-1 on whether to continue aggressive treatment
• One child is estranged and refuses to participate, but their non-response doesn't count as agreement
• Siblings have fundamentally different beliefs about quality of life versus life extension

In these situations, medical decisions can stall for days while the hospital tries to reach consensus. Meanwhile, the patient receives default care — which may include aggressive interventions they wouldn't have wanted.

Estranged Family Members

The hierarchy doesn't account for relationship quality. A spouse in the middle of a contentious separation (but with no filed court proceedings) is still Priority 2. A parent with a difficult history remains Priority 5 unless parental rights were formally terminated by a court. An estranged sibling counts in the majority calculation at Priority 6.

Unmarried Partners

If you're in a long-term relationship but not married or registered as domestic partners, your partner has no standing in the hierarchy. They fall to Priority 7 at best — behind your parents and siblings, even if your partner knows your wishes better than anyone.

Blended Families

Stepchildren have no status under ORS 127.635 unless they've been legally adopted. A stepchild who has provided years of caregiving is behind biological siblings who may have no relationship with the patient.

What Happens When Surrogates Disagree

If equal-priority surrogates can't reach consensus, the healthcare provider has two options:

1. Refer to the facility's Patient Care Advisory Committee — an internal ethics review process that evaluates the situation and makes a recommendation
2. Seek a judicial ruling from the county probate court — a formal legal proceeding that takes weeks and costs thousands in attorney fees

Neither option is fast. Both mean that during the dispute, someone else is making medical decisions under a default-care protocol that may not reflect the patient's wishes.

How an Advance Directive Changes This

An advance directive lets you skip the entire hierarchy. When you name a Health Care Representative in Section 2 of Form OHA 3905, that person has decision-making authority regardless of the surrogate priority order. Your appointed representative overrides:

• A spouse you're separated from
• Adult children who disagree with each other
• Parents you haven't spoken to in years
• Siblings who would deadlock

Your representative also gets written guidance from Sections 3 and 4 of the directive — your specific treatment preferences — instead of having to guess.

The Authority Difference

Default surrogates under ORS 127.635 have more limited authority than a formally appointed Health Care Representative. An appointed HCR can:

• Make all healthcare decisions within the scope of the directive
• Authorize facility admission for up to 18 days for dementia-related behaviors
• Access medical records and consult directly with the care team
• Override family members who disagree with the patient's documented wishes

A default surrogate makes decisions under closer medical supervision and may face more scrutiny from the healthcare team, especially if other family members challenge their authority.
