Dual Listing Explained
How it works, and who it helps on the liver transplant waiting list.
IN 30 SECONDS
Liver disease requires planning.
Hospitals have a responsibility to tell you about dual listing. You have the authority to be evaluated at more than one transplant center. Each center independently decides whether to add you to its waiting list. Travel and time off work are real costs, and they fall hardest on the patients who could benefit most.
Knowing this early, long before the welcome folder arrives, gives you the most options. This article explains what dual listing is and what to do next. At the bottom, you will find three free tools to help you act on what you learn.
Most patients hear about dual listing after they are evaluated at a transplant center, or even after they are listed for transplant. Sometimes, and quite often, it is mentioned in a passing manner, or in a way that does not fully register at the time you learn about it. Someone may have mentioned it during an early appointment. It may have been one bullet in a handout.
Most often, it shows up in the welcome folder, the packet of paperwork that comes when you begin the listing process, the one with consent forms to sign and information sheets to return. Somewhere in that folder is a brochure that says you are allowed to be listed at more than one transplant center. It is a real, accurate, useful document. UNOS, which produces it, has done its part. That brochure is important. This article is here to tell you why.
What does dual listing mean?
Dual listing means being on the waiting list at more than one transplant center at the same time. Each center can receive an organ offer for you. You do not have to choose one center over the other at the moment of the offer. The center where the offer arrives brings it to you, and you and your team decide whether to accept it.
When the count is more than two, the same practice is called multiple listing. The transplant community uses both terms. They mean the same thing.
Why is dual listing important?
Liver disease does not wait. The choices you make about where to be evaluated and where to be listed shape how the rest of your transplant journey unfolds. Most patients do not know those choices are theirs to make. By the time they could act on them, others have already acted for them.
Dual listing is one of the few decisions a patient can make to change the path. Time is the thing every patient on the waiting list is short on. Dual listing is one of the only choices that can buy more of it, by widening the set of donors who can reach you. It is not the right step for every patient, but for many, it is worth understanding well before you have to decide.
How can dual listing help me?
Being listed at a second center can change two things that matter.
First, it puts you in front of more donor organs. Liver allocation in the United States is based on the distance between a donor hospital and a transplant center. Each donor offer is matched to candidates at centers within a certain radius of that donor hospital. A patient listed at one center is considered for offers from donors near that center. A patient listed at two centers, in two different areas, is considered for offers from donors near both. Two locations, two pools of donors.
Second, it can change the score you need to receive a transplant. Each transplant program has a number called MMaT, the median MELD at transplant. It is the middle MELD score among patients who were actually transplanted at that program in the past year. MMaT varies significantly across the country. A center in one part of the country may transplant patients at a median MELD in the low 20s. A center in another part may not transplant most patients until their MELD is in the mid-30s. A patient with a MELD of 25 might receive a transplant quickly at the first center and never reach the threshold at the second. The same patient. The same score. Two different outcomes, depending on where they are listed.
Some studies have estimated that dual listing can shorten average wait times by several months. It does not guarantee this for any specific patient.
WHAT THIS MEANS
Dual listing only helps if the second center reaches a different pool of donor organs. Listing at two centers that share most of the same donors is mostly paperwork. Listing at a center in a different geographic area is what changes the math.
The same patient, the same score, two different outcomes, depending on where they are listed.
How do the lists actually work?
Most patients are told there is one waiting list, run by UNOS. That is true at one level. UNOS maintains a single national registry. But the way organs are actually offered is not one big list. It is many lists at once, sorted by distance from the donor hospital.
When a deceased donor liver becomes available, the system draws three circles around the donor hospital: 150, 250, and 500 nautical miles. It looks first at the most urgent patients in the closest circle, then works outward by medical urgency and distance.
You may hear hospitals or other patients talk about OPTN “regions.” Before February 2020, regions were the allocation unit. They are not anymore. Today, distance from the donor hospital is what matters.
Technology is extending that distance. As of September 2025, the FDA approved OrganOx perfusion devices for use during air transport. Centers with this capability can now accept donor livers from much further away than the 500-mile circle.
What this means for you: the donors who can reach you depend on where your transplant center is and what technology it uses. That is why where you list is one of the most important choices you will make.
A center two hours away in the same metro area may draw from many of the same donors as your current center. A center in a different state, or one that uses perfusion technology, is a different conversation. The geography matters more than the distance.
Who tends to benefit most?
Dual listing is not equally useful for every patient. Some situations make it more likely to change an outcome:
• Patients whose current center has a high MMaT relative to their own MELD score, especially when the score has been stable and is not climbing fast enough.
• Patients with liver cancer (hepatocellular carcinoma) whose MELD does not reflect the urgency of their disease, particularly when the wait at their current center exceeds the safe window for their tumor.
• Patients whose current center does not accept certain kinds of organs, such as DCD livers or organs preserved on a machine perfusion device, when a second center in a different area does.
• Patients with a potential living donor who can be evaluated at a center with more living-donor experience, while staying on the deceased-donor list at the original center.
• Patients who recently moved, who have family or support in another city, or who can credibly travel to a center in a different donor pool.
If none of these describe your situation, dual listing may still be worth understanding, but it may not change the outcome enough to justify the cost. If one or more do describe your situation, dual listing is exactly the kind of option this article exists to make sure you know about.
Is it allowed?
Yes. It has been allowed by federal policy since 1987. The transplant center where you are currently listed is required to tell you it is allowed. That is also federal policy.
Two policies govern this.
WHAT THE POLICY SAYS
OPTN Policy 3.2: Notifying Patients on their Options
Every transplant program must tell patients in writing that they are allowed to be registered at more than one transplant program.
WHAT THE POLICY SAYS
OPTN Policy 3.4: Multiple Transplant Program Registrations
Patients may be registered at more than one transplant program at the same time. Each program decides on its own whether to add a patient who is also listed somewhere else to its waiting list.
WHAT THIS MEANS
You are entitled to be told. You are entitled to seek a second evaluation. You are not automatically entitled to be added to a second center’s waiting list. Each one decides for itself. The door to ask is always open. It is built into the policy.
What happens to the time you have already waited?
Waiting time works differently than people expect. The time you have already waited at your first center does not double when you are listed at a second one. It stays where it is, or it can be moved, or it can be split between centers. The official term is “primary waiting time.”
WHAT THE POLICY SAYS
OPTN Policy 3.6.C: Waiting Time Transfer
Your longest accumulated waiting time at any one program is your primary waiting time. It can be transferred between programs or split between them. It cannot be added across them.
WHAT THIS MEANS
For liver candidates, waiting time matters less than medical urgency and geography. Dual listing does not double your priority. It gives you more paths to an organ offer. For some patients that path makes the difference. For others it does not. The point of this article is to help you tell which kind of patient you are.
What do I need to do in order to dual list, and what tools can help?
A second listing is real work. You will need a full transplant evaluation at the second center, including a medical history review, imaging, lab work, a psychosocial evaluation, and meetings with the second program’s transplant team. Some centers accept records and test results from your first center. Others require their own. Lab work and imaging often transfer; in-person evaluations with the second team almost always have to be redone. Each center decides. You will need to coordinate records between them. You will need to travel, sometimes more than once. You will need time off work for yourself and for whoever goes with you. You may need lodging. It is a lot. It is also doable. Other patients have walked this road before you, and they are alive because they did.
Three free tools can help with the parts of this work that an exhausted patient cannot reasonably be expected to do from scratch.
The Compare Centers Tool
A map of every U.S. liver transplant center, with the public data your team is already using. Filter by your MELD score, your blood type, your geography. See each center’s MMaT, the median MELD at transplant, to understand where the math at one center differs from the math at another. Filter for centers that use perfusion technology or the OrganOx device. The tool does not rank centers and does not recommend any specific one. It shows you the same public data your team uses, made readable for you. nationalfriends.org/your_options/
The Dual Listing Guide
A free 31-page workbook you can download and use to organize the dual listing process. Questions to ask each center. Records to request. Insurance steps. Travel logistics. A way to keep track of everything in one place so you do not have to hold it all in your head. Enter your email on our journey page to download it. nationalfriends.org/journey/
The National Friends Support Line
If you have questions and you would rather talk to a person, our support line is staffed by people who have been through this. They are not your transplant team and they do not give medical advice. They help you make sense of what you are seeing, what to ask, and where to go next. nationalfriends.org/support/
WHAT THIS MEANS
A map, a guide, a person to call. Use one. Use all three. They are built to work together.
How do I talk to my team about dual listing?
Most transplant teams respond well to patients asking about their options. They know the policy. They know dual listing is permitted. They expect the question from informed patients, and many appreciate it. Asking is not a betrayal of your team. It is a question about a recognized practice the policy already requires them to disclose.
If the conversation goes well, you have learned something good about your team. If it goes poorly, that is information too. Not a verdict on you, but a signal worth noticing. Either way, you walked in informed.
WHAT THIS MEANS
Dual listing is one of the most powerful options a liver transplant patient has. It is also one of the least explained. Now you know what it is, why it can help, and how it works. That alone changes what is possible.
The next decision is yours. Look at the Compare Centers tool. Download the Dual Listing Guide. Call the support line. Bring the questions to your team. Find out whether the math at a different center, in a different part of the country, might change the answer for you.
Your transplant team is the source of clinical decisions about you. The tools in this article help you walk into the next conversation knowing what is possible, what you are entitled to, and what to ask. Then the conversation belongs to you.
