Advance care planning is the process of thinking about, discussing, and documenting the medical care you’d want to receive if you became too ill to speak for yourself. It combines conversations with loved ones and, in many cases, legal paperwork that ensures your preferences are followed during a medical emergency or at the end of life. The conversations matter most, but the documents give those conversations legal weight.
People sometimes confuse advance care planning with hospice or end-of-life care specifically. It’s actually broader than that. It applies to any situation where you can’t communicate, whether that’s a sudden accident, a stroke, or the later stages of a chronic illness.
The Core Documents
Advance care planning typically produces one or more legal documents called advance directives. These only take effect when you can’t communicate your own wishes. The two most common are a living will and a durable power of attorney for health care, and they serve very different purposes.
A living will spells out specific treatments you do or don’t want. It tells doctors how to handle emergency treatment decisions: whether you want mechanical ventilation, CPR, tube feeding, or other interventions if you’re terminally ill or permanently unconscious. Think of it as a written set of instructions for your medical team.
A durable power of attorney for health care (also called a health care proxy) names a real person to make medical decisions on your behalf. This person can respond to situations your living will didn’t anticipate. Health care providers are legally bound to follow your proxy’s decisions as if they were your own. You can also limit your proxy’s authority, requiring them to consult certain family members first or restricting them to specific types of decisions.
These two documents complement each other. The living will covers the scenarios you’ve thought through in advance. The proxy handles everything else.
Who Can Serve as Your Health Care Proxy
In most states, your proxy must be at least 18 years old (19 in Alabama and Nebraska) and of sound mind. Beyond that, the American Bar Association recommends avoiding several categories of people: your health care provider or their spouse, the owner or operator of your residential care facility, anyone from a government agency financially responsible for your care, your court-appointed guardian, or someone who already serves as proxy for 10 or more other people.
A proxy’s responsibilities go beyond just saying yes or no to a treatment. They can decide which providers treat you, where you receive care, and whether to authorize access to your medical records. In many states, they can also make decisions about organ donation, autopsy, and what happens to your body after death. Choosing someone who genuinely understands your values, and who can advocate firmly under pressure, matters more than choosing the person closest to you on paper.
Medical Orders: DNR, POLST, and MOLST
Advance directives aren’t the only tools available. For more immediate medical situations, your doctor can write specific medical orders that health care professionals act on right away.
- Do not resuscitate (DNR) order: This goes into your medical chart at a hospital or nursing facility, telling staff not to attempt CPR or other life-support measures if your heart stops. An out-of-hospital DNR serves the same purpose but alerts emergency medical personnel outside a hospital setting.
- POLST or MOLST forms: Physician Orders for Life-Sustaining Treatment (POLST) and Medical Orders for Life-Sustaining Treatment (MOLST) are portable medical order forms that travel with you between care settings. They protect people who have strong preferences about life support, especially when they can’t speak for themselves and don’t have a proxy present. Research shows that having a portable order form like a POLST substantially decreases the time it takes to establish a DNR order when a patient arrives at a hospital unable to communicate.
Some states mandate these forms. Maryland, for instance, requires MOLST forms for all adults admitted to assisted living facilities, hospice, nursing homes, home health agencies, or dialysis centers.
How It Differs From Palliative and Hospice Care
Advance care planning, palliative care, and hospice care overlap but aren’t the same thing. Advance care planning is about documenting your preferences. It doesn’t involve receiving treatment itself. You can complete advance directives at any age and any stage of health.
Palliative care focuses on improving quality of life for people with serious or chronic illnesses. It addresses pain, symptoms, and emotional well-being, and it can begin early in a disease alongside curative treatment. Hospice care is a specialized form of palliative care reserved for people who are expected to live six months or less. It shifts the focus entirely from curing the disease to comfort and dignity.
Advance care planning ideally happens well before palliative or hospice care becomes relevant. The documents you create during planning then guide the care you receive later.
Why It Matters: What the Evidence Shows
A systematic review of the research found that advance care planning interventions led to significantly decreased hospitalization, including fewer ICU admissions. Ten separate reviews found increased patient satisfaction with medical care overall, and seven found increased satisfaction with clinicians specifically. Reduced hospitalization also translates to lower costs for both patients and health care systems, primarily by cutting emergency and unplanned admissions.
The practical benefit is straightforward: when your preferences are documented and your proxy knows what you want, you’re far less likely to receive unwanted aggressive treatment during a crisis. Your family also carries less of the burden of guessing what you would have chosen.
Medicare Coverage for Planning Conversations
Medicare covers advance care planning conversations with your doctor. These can happen in an office, hospital, skilled nursing facility, at home, or even through telehealth. When the conversation takes place on the same day as your annual wellness visit, with the same provider, Medicare waives both the coinsurance and the Part B deductible entirely. If it happens outside of a wellness visit, standard Part B cost-sharing applies.
Making Your Documents Work Across State Lines
If you split time between two states, your advance directives will generally be honored in both. Most states accept health care directives from other states as long as the documents were legally valid where they were created. A few states, however, will only honor out-of-state documents to the extent they comply with local law, and some states don’t address the question at all.
You have a constitutional right to direct your own health care, so your core wishes about life-sustaining treatment should be respected regardless of where you are. But practical details, like certain powers you’ve granted your health care proxy, could theoretically be refused in a state with different rules. The simplest fix is to check whether the second state has stricter witnessing or notarization requirements than your home state, and if so, add an extra witness or get your documents notarized to cover both. Making two separate sets of documents for different states is generally a bad idea, because signing a newer document can revoke the older one.
A patient representative at a hospital in the second state can usually tell you whether your existing documents will work without changes.
Getting Started
The most important step is the conversation, not the paperwork. Talk with the people closest to you about what matters to you: whether you’d want aggressive treatment to extend your life, how you feel about mechanical ventilation or CPR, what quality of life means to you, and who you’d trust to make decisions if you couldn’t. Then put it in writing. Your state’s health department or bar association typically offers free or low-cost advance directive forms that meet local legal requirements.
Once your documents are complete, give copies to your health care proxy, your primary care doctor, and any hospital where you regularly receive care. Keep a copy somewhere accessible at home. Review your documents every few years or after any major life change, like a new diagnosis, a marriage, or a move to a different state. Your preferences at 45 may not match your preferences at 70, and your documents should reflect who you are now.
