Idaho Living Will Requirements

Introduction

Key Things to Know

1. 1

   In Idaho, a living will is not its own separate document. It is the treatment-wishes portion of your Advance Care Planning Document (ACPD): your written statement of which medical treatments you want or want withheld if you cannot speak for yourself. It does not name who decides for you; that is a separate, optional part of the same ACPD.

2. 2

   A living will is not a last will and testament. A living will governs medical care while you are alive but unable to communicate; a last will and testament governs who inherits your property after you die. Most people preparing one eventually want the other too.

3. 3

   Idaho does not have a stand-alone living-will form. Idaho Code Sections 39-4501 through 39-4515 use one Advance Care Planning Document (ACPD) for both the treatment-wishes function and the health-care-agent-nomination function, and since a 2023 law change the statute does not use the phrase living will at all.

4. 4

   Idaho's advance directive used to state that it had no force during pregnancy. A federal court struck that requirement down in 2021. You now choose your own pregnancy instructions instead of having a default imposed on you.

5. 5

   Idaho does not require you to phrase your wishes using a fixed list of trigger conditions like a terminal condition or permanent unconsciousness. You write your own end-of-life care instructions and treatment objectives in plain language.

6. 6

   Registering your ACPD with the Idaho Department of Health and Welfare's Health Care Directive Registry is optional. It is not required for your document to be valid.

Idaho Requirements for Living Will

• Statutory Authority (Idaho Code Sections 39-4501 et seq.)

  Idaho does not have a legally separate living will statute. Idaho Code Sections 39-4501 through 39-4515 (the Medical Consent and Natural Death Act) create a single Advance Care Planning Document (ACPD) that can carry treatment wishes, a health care agent nomination, or both. Since a 2023 law change (House Bill 223), the statute no longer uses the term living will at all; it replaced the prior combined instrument, which had been named Living Will and Durable Power of Attorney for Health Care.

• Capacity Requirement (Idaho Code Sections 39-4503 and 39-4510)

  Idaho Code Section 39-4503 defines competence by comprehension: a person is competent if they understand the need for, nature of, and significant risks of the health care decision at hand, regardless of age. The 18-and-older requirement to execute an ACPD comes from Section 39-4510(1), not Section 39-4503.

• Persistent Vegetative State (Idaho Code Section 39-4502)

  Idaho Code Section 39-4502 does define persistent vegetative state as a condition of partial arousal, unresponsiveness, and no higher brain function. However, current law does not require an ACPD to address this condition as a mandatory trigger; it is simply an available term a person may choose to use inside their own free-text end-of-life care instructions under Section 39-4510(2)(h).

• Artificial Nutrition and Hydration (Idaho Code Sections 39-4502 and 39-4514)

  Artificial nutrition and hydration (ANH) is defined at Idaho Code Section 39-4502, Idaho's ACPD has no separate, specifically-initialed ANH election; a person addresses it, if at all, within their general end-of-life care instructions or treatment objectives. Section 39-4514(3) confirms a competent patient's ACPD-based direction to withhold or deny ANH must be honored by health care providers.

• Comfort Care and Pain Relief (Idaho Code Sections 39-4502 and 39-4514)

  Comfort care is defined at Idaho Code Section 39-4502 and required at Section 39-4514(4): anyone caring for a person for whom artificial life-sustaining treatment or artificial nutrition and hydration is withheld or withdrawn must still provide comfort care.

• Revocation and Suspension (Idaho Code Sections 39-4511A and 39-4511B)

  The current revocation section is Idaho Code Section 39-4511A. An ACPD may be revoked at any time by destruction, written signed revocation, oral expression, or any other action clearly manifesting intent to revoke. Idaho separately allows a person to SUSPEND, rather than fully revoke, an ACPD under Section 39-4511B, with the original terms resuming once a stated end condition is met, a distinct option most states do not offer.

• Physician Conscience Objection (Idaho Code Section 39-4513(2))

  Idaho Code Section 39-4513(2) lets a licensed independent practitioner or other health care provider who objects to a patient's wishes for ethical or professional reasons withdraw from the case without civil or criminal liability, provided they first make a good faith effort to help the patient find another willing provider. This is narrower than a general physician-compliance and transfer-of-care process; it is specifically a conscience-objection and transfer-assistance duty.

• Organ Donation (Idaho Code Sections 39-3401 et seq.)

  Idaho's Revised Uniform Anatomical Gift Act, beginning at Idaho Code Section 39-3401, lets a person authorize organ and tissue donation separately from their Advance Care Planning Document.

• HIPAA Authorization (45 CFR Section 164.508)

  Federal HIPAA regulations at 45 CFR Section 164.508 govern how a named health care agent can be authorized to access a person's protected health information once that part of the Advance Care Planning Document is in effect. Idaho's own ACPD statute lists a HIPAA release authorization among its optional elements.

• Patient Self-Determination Act Compliance (42 U.S.C. Section 1395cc)

  Federal law requires Medicare- and Medicaid-participating hospitals, nursing homes, and other facilities to inform patients in writing of their right under Idaho law to make an advance care planning document, including stating their own treatment wishes.

• POST Form Coordination (Idaho Code Section 39-4512A)

  A Physician Orders for Scope of Treatment (POST) form under Idaho Code Section 39-4512A is signed jointly by a licensed independent practitioner and the patient or their surrogate decision-maker, and by law cannot contradict the patient's last known expressed wishes. It is a separate, clinician-countersigned medical order, not part of the ACPD itself, and is typically used alongside one for patients with serious illness.

• Immunity Provisions (Idaho Code Section 39-4513)

  Idaho Code Section 39-4513 protects licensed independent practitioners, other health care providers, and health care agents from civil or criminal liability, and from discipline for unprofessional conduct, for good-faith acts or omissions carried out under a facially valid Advance Care Planning Document, DNR order, or POST form.

• Registry Information (Idaho Code Section 39-4515)

  Idaho's Health Care Directive Registry is now run by the Department of Health and Welfare, having been transferred from the Secretary of State. Registering is optional and does not affect an Advance Care Planning Document's validity either way. The statute allows a filing fee of up to ten dollars, though the department's current public guidance describes registering as free; revoking a registered document never carries a fee.

• No Witness or Notarization Required (Idaho Code Section 39-4510)

  Since a 2023 law change, Idaho requires only your name, date of birth, phone number, mailing address, signature, and the date signed for a valid Advance Care Planning Document. Witnesses and notarization are both listed only as optional elements you may add for extra formality; neither is required, and the statute sets no eligibility rules for who may serve as an optional witness.

• Current Pregnancy Choice, Not a Default Exclusion (Idaho Code Section 39-4510(2)(e))

  Idaho's advance directive form previously stated it had no force during pregnancy by default. A federal court ruled that requirement unconstitutional in April 2021 (Almerico et al. v. State of Idaho et al.), and the State issued an official notice replacing it with an opt-in choice: honor the directive fully during pregnancy, specify a particular treatment decision for pregnancy, or let a health care agent decide during pregnancy instead. No default rule applies unless the person completing the ACPD picks one of these options themselves.
