Advance Directives & Patient Self-Determination — Living Wills, Healthcare Proxies & DNR

The Patient Self-Determination Act of 1990 (PSDA) (42 U.S.C. §§ 1395cc(f), 1396a(w)) is the federal law requiring healthcare facilities that participate in Medicare or Medicaid to inform patients of their right to make advance directives — legal documents that specify your healthcare wishes if you become unable to communicate or make decisions for yourself. An advance directive is your voice when you can't speak — it tells your doctors and family what medical treatments you want (or don't want) and who should make decisions on your behalf. The two most common types are a living will (specifying which treatments you do or do not want — resuscitation, ventilators, feeding tubes, pain management) and a healthcare proxy (also called a durable power of attorney for healthcare — naming a person to make medical decisions for you). While the PSDA creates the federal requirement that facilities inform patients about these rights, advance directives themselves are governed by state law — each state has its own statutes specifying the requirements for creating, witnessing, and executing advance directives. Every state recognizes some form of advance directive, but the specific rules, forms, and terminology vary significantly. Approximately 37% of American adults have an advance directive — a percentage that increases with age (about 70% of adults over 65) but remains low for younger adults, leaving millions without documented end-of-life wishes. See HIPAA for the privacy protections governing your medical records and Elder Justice Act for related protections for older adults.

Current Law (2026)

Legal Authority

• 42 U.S.C. § 1395cc(f) — Medicare provider agreements: requirement to maintain written policies on advance directives and inform patients
• 42 U.S.C. § 1396a(w) — Medicaid state plan requirements: same advance directive information obligations
• State advance directive statutes — All 50 states + D.C. have enacted advance directive laws (varying significantly in requirements)
• Uniform Health-Care Decisions Act (1993) — Model law adopted (in whole or part) by approximately 12 states

How It Works

The Patient Self-Determination Act does not create the right to make advance directives — that right comes from state law. What the PSDA does is require every Medicare- and Medicaid-participating hospital, nursing facility, home health agency, hospice, and HMO to inform adult patients at admission or enrollment of their state-law rights to accept or refuse medical treatment and to make advance directives; document in the medical record whether a directive exists; not condition care or treatment on whether the patient has one; and provide staff and community education on the subject.

The two most common advance directive instruments work differently. A living will is a written document specifying treatment decisions — CPR and resuscitation, mechanical ventilation, tube feeding, dialysis, antibiotics for life-threatening infections, and pain management — that speaks for you only when you cannot speak for yourself; it doesn't apply when you can communicate. A healthcare proxy (or durable power of attorney for healthcare) names a specific person as your agent to make decisions when you lose decision-making capacity — most experts consider this more important than a living will because a proxy can respond to unanticipated medical situations a living will might not address. For seriously ill or frail patients, a POLST (Physician Orders for Life-Sustaining Treatment) goes further: it's a physician-signed medical order that translates patient wishes into immediately actionable clinical instructions that travel between care settings. Approximately 45 states have POLST programs. Interstate portability is a practical gap — most states have provisions recognizing out-of-state advance directives that substantially comply with in-state requirements, but there is no federal portability guarantee; people who spend significant time in multiple states should consider executing directives that comply with each state's specific requirements.

How It Affects You

If you're an adult without an advance directive — of any age: The most common reason for not having one is "I'll get to it." The most common consequence is a family crisis. An advance directive is not just for the elderly; sudden illness, accidents, and unexpected diagnoses happen at every age. The two documents you need are: (1) a healthcare proxy (naming a specific person to make medical decisions for you if you cannot make them yourself — more important than a living will because a proxy can respond to situations you didn't anticipate), and (2) a living will (specifying your wishes on CPR, mechanical ventilation, artificial nutrition, and comfort care). Creating both takes about 30 minutes. Free state-specific forms are available through the National Healthcare Decisions Day website (nhdd.org), Five Wishes (agingwithdignity.org), or your state's attorney general. Most states require two adult witnesses (who aren't your heirs) or a notary — check your state's specific requirements. Once completed, give copies to your healthcare proxy, your primary care physician, and anyone who might accompany you to an emergency room.

If you're over 65 or have a serious illness: Advance directives are particularly important for Medicare Part A beneficiaries facing hospitalization decisions and for those planning for long-term care. Your advance directive should be accompanied by a POLST (Physician Orders for Life-Sustaining Treatment) if you are seriously ill or frail. Unlike a living will (a legal document that takes effect when you lose decision-making capacity), a POLST is a medical order signed by your physician that is immediately actionable by any medical provider, including EMS. A POLST traveling with you means that first responders know your wishes before you arrive at the hospital. Medicare now pays for advance care planning conversations with your doctor (CPT codes 99497–99498) — these conversations can help you articulate your wishes clearly enough to create meaningful documents. If you've had a major diagnosis (cancer, heart failure, COPD, dementia progression), have a specific conversation with your physician about what resuscitation, ventilation, and ICU care would realistically mean for you, not just abstractly.

If you're a family member or caregiver for someone who doesn't have an advance directive: You face two risks if your loved one becomes incapacitated without a directive: (1) you may not know what they wanted, and (2) family members may disagree — creating conflict during an already traumatic time. In the worst case, disagreements among family members about treatment decisions require court intervention (guardianship or conservatorship proceedings), which are expensive, slow, and deeply painful. An advance directive should be part of a broader estate plan that also addresses financial powers of attorney. If your parent or spouse doesn't have a healthcare proxy, start a conversation — many people are more willing to create one than to have it sit unused. Normalize it as practical planning, not a discussion about dying. If your loved one is already incapacitated without a directive, consult the hospital's social worker or patient advocate about your state's surrogate decision-making hierarchy — most states have statutes specifying who can make medical decisions for an incapacitated person without a proxy (typically: spouse, adult children, parents).

If you travel or split time between states: Interstate portability of advance directives is not guaranteed by federal law. Most states have portability provisions recognizing directives from other states if they substantially comply with receiving-state requirements — but "substantially comply" is vague and fact-specific. If you regularly spend time in more than one state, the safest approach is to execute state-specific documents for each state where you receive regular medical care. The Five Wishes document (now legally valid in 46 states) is designed to be broadly portable and satisfies requirements in most states. For POLST forms — which are medical orders, not just legal documents — the form and validity vary significantly by state; a POLST issued in California may or may not be honored by providers in Texas. If you spend significant time in a different state from where your regular physician practices, discuss POLST portability with your doctors directly.

State Variations

Advance directives are governed by state law — significant variation:

• Terminology varies: "living will," "advance healthcare directive," "healthcare power of attorney," "durable power of attorney for healthcare" — different states use different terms for similar documents
• Witness requirements: Some states require 2 witnesses; others require notarization; some accept either
• Restrictions on proxy choice: Some states prohibit your attending physician or certain family members from serving as proxy
• Specific forms: Some states have statutory forms (e.g., California's Advance Health Care Directive form); others accept any written document meeting basic requirements
• POLST programs: ~45 states have POLST/MOLST programs, but the forms and scope vary

Implementing Regulations

• 42 CFR Part 489.102 — CMS requirements for hospitals, nursing facilities, home health agencies, hospice, and HMOs to provide written information to patients about advance directives (Patient Self-Determination Act implementation)
• 42 CFR Part 418 — Medicare hospice conditions of participation, including requirements for advance directive documentation and honoring patient end-of-life wishes
• 45 CFR Part 164 — HIPAA Privacy Rule provisions governing personal representatives and healthcare decision-making, including the rights of legally authorized agents and proxies to access protected health information

Pending Legislation

Advance directive portability and standardization bills are periodically introduced. See Medicare and Healthcare Reform for related legislative activity in the 119th Congress.

Recent Developments

The COVID-19 pandemic dramatically highlighted the importance of advance directives — with thousands of patients unable to communicate their wishes during critical illness. Advance care planning completion rates increased during and after the pandemic. Medicare reimburses for advance care planning conversations (CPT codes 99497–99498) as part of annual wellness visits — encouraging physicians to discuss end-of-life wishes with patients. Electronic advance directive registries (allowing digital storage and retrieval of directives by healthcare providers) are expanding in several states. The POLST paradigm continues to spread, with national coordination through the National POLST organization.

• Medical aid in dying expansion and advance directives (2024-2026): As of May 2026, thirteen states plus Washington, D.C. have enacted medical aid in dying (MAID) laws allowing terminally ill patients to self-administer a lethal prescription. Recent additions include Delaware (2025), Illinois (signed December 2025; effective September 2026), and New York (signed by Governor Hochul on February 6, 2026). Advance directive forms in MAID states now typically include sections addressing MAID requests — creating coordination questions between traditional advance directive law (PSDA) and state-specific MAID statutes that have different form requirements and witness standards.
• OBBBA and Medicare advance care planning reimbursement: The One Big Beautiful Bill Act's Medicare payment reductions did not specifically target advance care planning CPT codes (99497-99498), which were enacted with bipartisan support and have been consistently reimbursed since 2016. However, OBBBA's broader 2% Medicare physician payment reductions would apply proportionally to advance care planning conversations. Primary care physicians — the primary deliverers of advance care planning services — have the lowest Medicare reimbursement rates relative to specialists, making even modest cuts disproportionately burdensome.
• AI and advance directive documentation: Healthcare technology companies have introduced AI-assisted advance directive completion tools — chatbots and structured interviews that guide patients through healthcare wishes and generate legally compliant advance directive documents. Several hospital systems have piloted these tools with elderly patients during elective procedure pre-admission processes. State bar associations have generally not classified AI-assisted advance directive completion as unauthorized practice of law when the AI generates a standard statutory form rather than legal advice, but the legal landscape remains unsettled.
• Dementia-specific advance directives — state law innovation: Standard advance directives allow patients to document wishes if they lack decisional capacity — but they rarely address the specific progression of Alzheimer's and other dementias, where patients may retain partial capacity for years. Several states (Oregon, Washington, California) have enacted or proposed dementia-specific advance directive forms that allow individuals to specify care preferences at different stages of cognitive decline, including whether to accept assisted feeding when the patient can no longer eat independently. Federal Medicare and Medicaid regulations do not specifically recognize dementia-specific directives, creating interoperability questions at federally-regulated facilities.
