What a nurse navigator does, and how to get one

The Oncology Nursing Society defines an oncology nurse navigator as "a professional RN with oncology-specific clinical knowledge who offers individualized assistance to patients, families, and caregivers to help overcome healthcare system barriers." Strip the committee language and it is this: a nurse who knows cancer, assigned to you, whose job is the system rather than the disease.

The role was invented at Harlem Hospital in 1990 by a surgeon named Harold Freeman, who kept watching women from the neighborhood arrive with breast cancer too advanced to cure. He paired free screening with people whose only job was to walk patients from an abnormal result to treatment without losing them along the way.

Over the following years the share of his patients diagnosed at stage I rose from 6 percent to 41 percent, and five-year survival rose from 39 percent to 70 percent. That figure belongs to the screening and the navigation together, not navigation alone, but it is the result the whole field was built on.

Two things follow from the definition. A nurse navigator is a nurse first, so they can read your pathology report with you, explain why the oncologist wants a PET scan before surgery, and recognize when a symptom you mention on the phone needs a same-day call to the doctor.

And a navigator is assigned to the patient, not to a doctor. The surgeon has nurses; the medical oncologist has nurses; the navigator belongs to you, across all of them. At larger centers that can mean more than one. A breast program may have a surgical navigator and a medical-oncology navigator, and families sometimes learn they have been handed from one to the other only when an email goes unanswered.

The other person who gets called a navigator is the patient navigator, sometimes called a lay or community navigator. The Society's definition is nearly identical except for one phrase: "a trained nonprofessional or volunteer." They are often superb at the practical work, and the Association of Oncology Navigators is explicit that a patient navigator "does not have or use clinical training." If you are not sure which one you have, ask. "Are you a nurse?" is a normal question and nobody is offended by it.

The letters after the name tell you too. RN means a registered nurse. OCN is the general oncology nursing certification, CBCN the breast-care one, and ONN-CG is the navigation credential for nurses, which requires at least three years of navigation work. OPN-CG is the same credential for navigators who are not nurses, such as social workers and lay navigators.

You may also meet a financial navigator, who works on cost and coverage, and a clinical-trial navigator, who matches patients to studies. Both are useful and neither is a substitute for the nurse.

The job descriptions list twenty duties. In practice a navigator's week is built from six.

They translate. After the appointment where you heard "triple negative" and "neoadjuvant" and nothing else, the navigator is the person who calls the next day and explains both words, slowly, and again the week after if you need it. Their education role is written into the competencies, and it is the one families value most.

They sequence. A new cancer diagnosis can generate a biopsy, a staging scan, a surgical consult, a medical-oncology consult, a radiation consult, genetic testing, a port placement, and a tumor board review, at four different departments. The navigator knows which must come first, books them in the right order, and notices when one has quietly fallen off the schedule.

They remove barriers. No ride to radiation, a job that will not release you for five weeks of daily treatment, a prescription the pharmacy says needs prior authorization, a pending disability form. Navigators have a list of resources for each of these and the phone numbers that go with them.

They watch. When you mention on the phone that the nausea has been going on for four days, a nurse navigator recognizes that as something the oncologist needs to hear today, and makes sure they hear it.

They connect. Social work, financial counseling, a dietitian, a clinical-trial coordinator, a support group, a wig program. The navigator is the switchboard.

And they keep the story straight. Across months, the navigator is often the only person on the team who has been on every call. One breast-cancer navigator, interviewed about her work in 2023, described tracking patients with a paper binder and a spreadsheet because the electronic record was never built for it.

That is worth knowing for two reasons. It is why a good navigator is so valuable, and it is why the family's own record of what was said and when is not redundant. Our guide to organizing medical records is the same record, kept at home.

The limits matter as much as the duties, because families get hurt when they expect the wrong things.

They cannot change your treatment. A navigator can explain the plan and carry your questions to the oncologist, but they do not prescribe, adjust doses, or order scans. If you want a medication changed, the navigator gets you to the person who can do it.

They are not a second opinion. The navigator works for your care team, and a good one will be honest with you, but they are not an independent reviewer of whether the plan is right. That is a different process with its own mechanics, and we cover it in how to get a second opinion, including how to get the slides and scans released.

They are not your insurer's case manager. A navigator can help with a prior authorization and can tell you who to call, but the decision about what the plan will pay for sits with the insurer, and the insurer's own nurse case manager, if you are assigned one, works for the insurer. Keep the two straight in your head. They will both be kind on the phone and they answer to different people.

They are not available around the clock. Navigators keep office hours. A new symptom at 9 p.m. goes to the oncology on-call line, not the navigator's voicemail. Ask on the first call what to do after hours, and write the number down where everyone in the family can find it.

And they are not limitless. A 2015 national survey of 247 navigators found that more than half worked in programs seeing over 25 patients a week, that nearly half cited confusion about their role among their own colleagues as a challenge (the most common one reported), and that 57 percent were self-taught.

The professional bodies have since published guidance saying plainly that navigators should not be doing clerical work, which tells you that many were. None of this is a reason not to use your navigator. It is a reason to make your asks specific and to keep your own copy of the plan.

At many cancer centers the navigator contacts you, not the other way around. Fred Hutch, for instance, tells new patients the navigator will reach out within one to two business days of the first appointment being scheduled, and that no appointment with the navigator is needed. If you are a week past diagnosis and no one has called, that is the moment to ask.

Ask in the right place. The navigator is usually attached to the cancer program, not to an individual doctor's office, so the question goes to the cancer center's main line or the clinic's scheduling desk: "Does the cancer program have a nurse navigator, and can I be connected to the one for breast cancer?" If the answer is "we have a patient navigator," that is worth having, and you can still ask whether a nurse is available for clinical questions.

One thing families are often told is no longer quite true: that any hospital accredited by the Commission on Cancer is required to have a navigation program. Under the previous standards it was. Since 2020, Commission on Cancer Standard 8.1 no longer requires accredited hospitals to run a navigation program. It asks each cancer committee to pick at least one barrier to care every year and address it, and navigation is one common way to do that, not a mandate.

By the Commission's own count there are roughly 1,500 accredited programs, and they treat about 70 percent of newly diagnosed patients. Accreditation makes a navigator likely, not guaranteed. Ask anyway.

If you are being treated at a small community practice with no navigator at all, you have three fallbacks, all free. The American Cancer Society runs a 24-hour line at 1-800-227-2345 staffed by cancer information specialists, and its ACS CARES program can match you with a trained volunteer. CancerCare (1-800-813-4673) provides licensed oncology social workers for counseling, case management, and financial help. The Patient Advocate Foundation (1-800-532-5274) assigns free case managers for insurance appeals and access problems in serious illness.

And if what you need is someone who answers only to you, there is a growing profession of independent patient advocates, some of them nurses, who charge by the hour. Look for the BCPA credential (Board Certified Patient Advocate). If you are considering hiring one, our page for patient advocates explains how they work with a family's records.

At most hospitals, navigation is funded inside the cancer program, through the hospital's budget or through philanthropy, and the patient is never billed for it. Hospitals that say so explicitly, like Fred Hutch ("free of charge"), are describing the common arrangement. The Oncology Nursing Society's 2025 position statement says navigation "should not add to financial toxicity risk." If a navigator has been helping you for months and no charge has appeared, that is the normal pattern.

There is a newer exception, and it is worth understanding before a surprise line appears on a Medicare summary. Beginning in 2024, Medicare created billing codes for what it calls Principal Illness Navigation: G0023 for the first 60 minutes of navigation in a month and G0024 for each additional 30 minutes. The navigator delivers the service, but it is billed under the physician or other practitioner who is treating you, for a serious condition expected to last at least three months. Cancer is the textbook case.

The catch is that these services fall under Medicare Part B, so the deductible and the usual 20 percent coinsurance apply. A Medigap plan can cover that share. Without one, it is a real bill.

Two protections are built in. The practice must get your consent before billing navigation, must tell you that cost sharing applies, and must document it. So if you are on Medicare and a navigator asks you to agree to "navigation services," that is the moment to ask the plain question: "Will I be billed for this, and how much?" Adoption has been slow, and the coinsurance is one reason navigation journals cite. The answer should be clear before you say yes.

If a navigation charge appears on a Medicare summary and you do not remember agreeing to it, ask the practice for the consent note. Keep the summary with the rest of your records.

Most families take the first navigator call empty-handed, because it arrives before they know what to ask. Six questions cover the ground.

1. Are you a nurse?

2. What is the best way to reach you, and how long do you usually take to respond?

3. Who do I call after hours?

4. Which appointments are already scheduled, in what order, and is anything still waiting on a referral or an authorization?

5. Can my daughter (or spouse, or sibling) call you directly, and what do you need from me to allow that?

6. The one people forget: will you still be my navigator after treatment ends?

The caregiver question deserves a note. Federal privacy law already allows a clinic to share information with family members involved in your care, as long as you do not object. In practice most programs ask you to name those people on a form. Sign it early.

The person doing the phone work is often not the patient, and a navigator who can speak freely to the daughter making the calls is worth twice as much as one who has to say "I'd need to talk to your mother about that." If the program has no form, the records release in our printables does the same job for documents.

Tell the navigator three things in return: the practical barrier you are most worried about (work, transport, money, childcare), the name of any other doctor already involved who is not at this center, and whether you want results explained to you before or after you see them in the portal. That last one shapes how they call you for the next six months. If you have not decided, our guide on reading results before the doctor calls lays out the tradeoff.

For the oncologist appointment itself, the navigator can help you prepare but will not be in the room. The questions to ask your oncologist are a separate list, and the navigator is the right person to go over them with before the visit.

This is the part nobody warns families about. Many navigation programs are built around active treatment: diagnosis through the last infusion or the last radiation session. At that point some programs formally close the case. One program described in the Oncology Nursing Society's journal "stops active navigation at the time the patient completes active treatment and transitions into survivorship." The person who called every week for eight months stops calling, by design.

The timing is hard, because the end of treatment is when many people report feeling lost. The scans are less frequent, the team is less present, and the question "what now?" has no appointment attached to it. If your program has a survivorship clinic or a survivorship care plan, the navigator's last job should be the handoff to it. Ask for that by name.

If there is no survivorship program, the fallbacks in the previous section still apply, and a primary care doctor who has the full treatment summary becomes the person keeping track. That handoff works only if the summary actually reaches them. The treatment summary, the last scan report, and the follow-up schedule are the three documents to get into one place before the navigator signs off.

If treatment is not ending but changing direction, toward comfort rather than cure, the navigator is also usually the person who introduces palliative care; we explain what that does and does not mean in palliative care vs hospice.

The role began in oncology and most navigators still work there, but the same job now exists in other serious illnesses, usually wherever a hospital has noticed patients falling through a gap. Stroke programs use nurse navigators to manage the weeks after discharge, and one 2023 study of patients treated with clot-busting drugs found those followed by a navigator had about half the rate of unplanned readmission within 30 days. Heart failure programs use them for the same work after a hospital stay. Transplant, neurology, and cardiology programs have navigators too, though under a range of titles.

If the diagnosis in your family is not cancer, ask the same question in the same place: "Does this program have a nurse navigator?" The answer is more often no than in oncology, and when it is, the case manager assigned at discharge is the nearest equivalent for the short term, and the primary care office is the nearest equivalent for the long term. For aging parents with several conditions and no single program, the questions to ask a specialist checklist includes the coordination questions a navigator would otherwise handle.

Navigation is popular, often funded by philanthropy, and rarely questioned, so it is fair to ask what it has been shown to change. The honest answer is: the speed and completeness of getting from an abnormal result to treatment, and how patients feel about their care. Not, so far, survival.

The biggest test is the Patient Navigation Research Program, which followed 10,521 people with abnormal cancer screening results. Published in 2014, it found no benefit in the first 90 days, then a clear one: between 91 and 365 days, navigated patients were about 50 percent more likely to have their diagnosis resolved and about 40 percent more likely to have started treatment.

The detail worth keeping is where the benefit came from. It was largest at the centers with the longest delays under usual care. At a well-run center, navigation may change little. At a slow one, it changes a great deal.

A 2024 review of 59 studies found that 70 percent of those measuring whether treatment got started showed a significant improvement with navigation, and 87 percent of those measuring satisfaction did. It also noted that no survival data could be pooled. Claims that navigation improves survival rest on observational comparisons, which are suggestive and not proof.

The financial case is stronger than families might guess. A University of Alabama at Birmingham program that navigated 6,214 Medicare patients, matched against 6,214 who were not, reported in 2017 that costs fell by $781 more per patient per quarter in the navigated group, with emergency visits, hospitalizations, and ICU admissions each declining faster. That is the study hospitals cite when they fund a program, and it is why a navigator is a bargain for the hospital as well as for you.

Read all of that as a nurse would. A navigator will not change the biology of the disease. What they change is whether the biopsy happens this week or in six, and whether anyone noticed the symptom you mentioned in passing. Those are the things families lose sleep over, and they are exactly the things the evidence says navigation fixes.
