Default Health-Care Surrogate Priority in Idaho

At a glance

Requirements one by one

When the default route opens

Section 39-4504(1) applies when a patient is then unable to consent under the chapter. A person who comprehends the need for, nature of, and significant risks ordinarily inherent in contemplated services can consent personally (§ 39-4503). A surrogate must have that same comprehension and may not authorize care contrary to the patient’s advance care planning document or wishes expressed while capable (§ 39-4504(1)).

Care or setting covered

The chapter covers hospital, medical, dental, surgical, and other health services. It preserves the separate laws governing hospitalization or commitment for mental illness or developmental disability, along with specified pregnancy-prevention and abortion provisions (§ 39-4501(1)–(2)).

Guardian or appointed agent

A court-appointed guardian is first, followed by a health-care agent named in an advance care planning document whose conditions for the agent to act have been met. A spouse follows them (§ 39-4504(1)(a)–(c)).

Family and other people

After a spouse, the statute lists an adult child, a parent, a designee under a parental delegation, then any relative. A competent person who represents themselves as responsible for the patient’s health care follows the relative class (§ 39-4504(1)(d)–(h)). The parental-delegation route is primarily relevant to minors; its place in the full statutory consent list does not put it ahead of an adult patient’s child or parent.

Decision within one class

Section 39-4504(1)(d), (g) gives adult children and relatives their respective ranks but leaves selection among multiple people at either rank unstated. The section provides no named vote or tie process for that situation.

Decisions limited or excluded

A surrogate cannot override the patient’s directive or capable wishes (§ 39-4504(1)). Under § 39-4514(3), the law protects feeding, artificial nutrition and hydration, other life-sustaining services, and comfort care when provision is directed through one of the named routes; it also addresses a direction to deny care. Section 39-4514(5) presumes consent to CPR unless one of its listed directive, communicated-wish, POST, or DNR exceptions applies. The chapter does not require nonbeneficial medical treatment (§ 39-4514(6)).

No surrogate or disputed authority

When a medical emergency or serious danger from delay exists and the patient cannot communicate wishes, the attending provider may authorize or provide appropriate services under § 39-4504(1)(i). Obtaining sufficient consent is the attending licensed independent practitioner’s duty (§ 39-4508). The general consent ladder itself leaves a dispute between equally ranked relatives unresolved; the emergency clause has its own stated prerequisites.

What trips people up

The current § 39-4504(1)(f) refers to a parental delegation under § 15-5-104. An enacted replacement effective January 1, 2027 changes only that citation in the consent ladder to § 15-5-128; the future text is already shown on the official § 39-4504 page. Idaho S1240, chapter 79, is signed and scheduled for that date: https://legislature.idaho.gov/sessioninfo/2026/legislation/S1240/.

Common questions

Can a friend consent if no relative is available?

A competent person who represents themselves as responsible for the patient’s health care appears after “any relative” in § 39-4504(1)(g)–(h). The person must be able to understand the contemplated services and cannot contradict the patient’s directive or known capable wishes.

May the provider proceed in every case where a relative cannot be found?

Section 39-4504(1)(i) requires a medical emergency or serious danger to life or health from withholding or delay, plus inability to communicate wishes. It permits the attending provider to authorize or give appropriate care in those circumstances.
