A Do Not Resuscitate order written during a hospital or nursing home stay has no built-in expiration date. It stays in effect for as long as you remain a patient at that facility, unless you or your authorized decision-maker revokes it. Out-of-hospital DNR orders are different: some states require them to be renewed by a physician on a set schedule, with 90 days being a common interval. Because these orders are governed at the state level, how long a DNR lasts ultimately depends on where it was signed and where you plan to use it.
In-Hospital and Nursing Home DNR Orders
A DNR order written while you are admitted to a hospital or living in a nursing home remains active for the duration of that stay. There is no countdown clock, no renewal date, and no automatic review deadline. The order sits in your medical record and guides your care team until one of two things happens: you or your authorized surrogate revokes it, or your physician, in consultation with you, decides a change is appropriate.
The order does not automatically follow you out the door. When you are discharged, the in-hospital DNR no longer applies in the outside world. If you want emergency responders to honor your wishes at home or during transport, you need a separate out-of-hospital DNR, which is a distinct document with its own rules.
Out-of-Hospital DNR Orders
Out-of-hospital DNR orders are the version you use if you live at home, in assisted living, or in any non-hospital setting. Every state has some form of out-of-hospital DNR protocol or portable medical orders program.1MSD Manual Professional Edition. Do-Not-Resuscitate (DNR) Orders and Portable Medical Orders These forms, along with wallet cards and identification bracelets, tell paramedics and other first responders to honor your wishes before you ever reach a hospital.
Unlike in-facility orders, some out-of-hospital DNRs expire after a set period. Where states impose a deadline, 90 days is a common timeframe, after which a physician has to renew the order to keep it valid. Not every state requires periodic renewal, so the answer depends entirely on your jurisdiction. If you have an out-of-hospital DNR, ask the issuing physician whether it needs to be renewed and mark the date if it does. An expired form gives paramedics no legal basis to withhold CPR, even if your wishes have not changed.
How a DNR Ends Early
The one thing that always shortens a DNR’s lifespan is revocation. You can cancel your DNR at any time, for any reason, as long as you have the mental capacity to make medical decisions. In most states you do not need to put it in writing. Telling your doctor or nurse that you want the DNR revoked is enough, and the revocation should be documented in your medical record immediately.
If you have lost the ability to make decisions, only your legally designated healthcare proxy or the agent named in your medical power of attorney can revoke the DNR on your behalf. A spouse, adult child, or close friend who has not been formally designated cannot override it, no matter how well-intentioned they are.
Once a DNR is revoked, destroy every physical copy of the form, including wallet cards and bracelets. An outdated form floating around in a drawer or on your wrist can cause exactly the kind of confusion that leads to your current wishes being ignored during an emergency.
Transfers, State Lines, and New Physicians
Moving between care settings is one of the most common ways a DNR quietly stops working. When you transfer from a hospital to a nursing home, or between facilities, your DNR order does not always follow automatically. The receiving facility may need to write a new order, and that only happens if someone communicates your wishes during the handoff.
Crossing state lines adds another layer. DNR orders are governed by state law, and each state has its own forms, requirements, and standards. Most states will honor an out-of-state advance directive, but some will only recognize it if it meets their own legal requirements. There is no federal law guaranteeing universal portability. In practice, providers rarely refuse to honor a clearly documented DNR from another state, but the legal footing is shakier than most people realize. If you are relocating or spending significant time in another state, the safest option is to execute a new DNR that complies with the local rules. A local physician can help you complete the correct forms, and bringing a copy of your existing order speeds things up.
Changing your primary doctor can also create a gap. Your new physician needs to review and acknowledge your existing DNR. Do not assume this happens automatically when records transfer. Mention it at the first appointment.
DNR Orders During Surgery
Even a valid, unexpired DNR may be paused for a specific event. Anesthesia can cause the very problems a DNR is designed to address: your blood pressure might drop, your heart rhythm can become irregular, or you might stop breathing. In most cases the problem is temporary and easily reversed by the surgical team, which makes applying a blanket DNR during surgery more complicated than it sounds.
Hospital policies differ. Some facilities automatically suspend all DNR orders during surgery and the immediate recovery period. Others require a preoperative conversation. The American Society of Anesthesiologists has pushed back against automatic suspension, calling it insufficient to protect patient autonomy.2American Society of Anesthesiologists. Statement on Ethical Guidelines for the Anesthesia Care of Patients With Do-Not-Resuscitate Orders
Under the ASA’s guidelines, you and your anesthesiologist should agree on one of three approaches before the procedure:
- Full suspension of the DNR for the duration of surgery and immediate recovery, with the team using whatever resuscitation measures the situation calls for.
- A limited suspension defined by specific procedures, where you consent to some interventions like airway management but decline others like chest compressions.
- A limited suspension defined by goals and values, giving the anesthesiologist discretion to intervene only when a complication is likely reversible and consistent with your overall wishes.
Whichever you choose should be documented in your medical record before the procedure begins. If you have a DNR and surgery is on the table, raise the topic early. Do not assume the surgical team will bring it up first.
A DNR Is Not a POLST
If you are trying to figure out how long a single document will protect your wishes across settings, know that a DNR and a POLST are not the same tool. POLST stands for Physician Orders for Life-Sustaining Treatment. Some states use different names such as MOLST, POST, MOST, or COLST, but the concept is similar, and nearly all states now have some version of the program.3National POLST Collaborative. State Programs
A DNR answers a single question: should CPR be attempted? A POLST covers CPR and also records your preferences on mechanical ventilation, feeding tubes, antibiotics, and whether you want comfort-focused care or full intervention. It functions as a set of standing medical orders rather than one instruction.
The biggest practical difference is portability. A POLST travels with you across care settings. Moving from a hospital to a nursing home to hospice care, the same POLST follows your record and carries the weight of a physician’s order at each stop. A standard DNR is typically tied to the facility where it was written. POLST forms are usually printed on brightly colored paper so they stand out in a chart during transfers.
POLST forms do not technically expire in most states, but they should be reviewed whenever your health changes significantly or you move to a new care setting. An outdated POLST that no longer reflects your wishes can create confusion during an emergency, so treat any major health change as a prompt to revisit the form with your doctor.
