Healthcare Navigation: What It Is and Who Does It

What healthcare navigation actually is

In short: Healthcare navigation means one person helps you follow through on care: referrals, equipment, bills. For eligible patients, Medicare Part B has had billing codes for it since January 2024.

The doctor says your father needs a cardiology referral, a walker and a follow-up visit. Then nothing happens. Nobody is lazy. The recommendation was made in one building, the referral has to be booked in another, and the walker comes from a third company that wants a form from the first. The tell is rarely medical. It's logistical.

If your parent is on Medicare and you are the one making those calls, Navigate Care explains how a navigator takes on that follow-through, and how it differs from other kinds of help, on its compare page.

The research world has been using the word for longer than the insurance world. The National Cancer Institute's Patient Navigation Research Program described it as "support and guidance offered to vulnerable persons with abnormal cancer screening or a cancer diagnosis", with the aim of overcoming barriers to timely, quality care. Strip out the cancer and you have the everyday meaning. Someone whose job is to get you from "the doctor recommended it" to "it happened".

A navigator does not treat, diagnose or give medical advice. The doctor does that. The navigator coordinates.

What the work looks like in a real week

Here is the sort of list a navigator works through. None of it is clinical.

• Book the specialist the surgeon recommended, and rebook it when it's cancelled.
• Find out why the oxygen or the walker hasn't arrived, and who is holding the order.
• Check after a hospital discharge that the follow-up visit and the home health referral exist.
• Read a denial letter with you and work out what to ask next.
• Keep one running list of every doctor, medicine and date, so you don't have to.

Families usually do all of this alone, in lunch breaks. The site's own figure is that about 70 million people are on Medicare, and two-thirds of them manage more than one chronic condition. That is a lot of appointments with nobody holding the thread.

You are not failing at this. The system splits one person's care across offices that don't talk to each other, and then expects the family to be the switchboard.

Five kinds of navigation, side by side

The word covers several different jobs. People searching for it often land on pages written for employers, which describe a benefit a company buys for staff. That is real, and it is one kind. If you are caring for a parent, these are the ones you are likely to meet.

Kinds of healthcare navigation, and what each is for

No one kind wins. A SHIP counsellor is the right first call for one confusing plan. A hospital navigator is the right person while your mother is still in the bed. The question is who is still there a month later. Our compare page goes through the categories in more detail.

How Medicare pays for navigation

This is the part nobody explains. Since January 2024, Medicare Part B has had billing codes for navigation. Community Health Integration uses G0019 and G0022. Principal Illness Navigation uses G0023 and G0024.

The CMS fact sheet for the 2024 physician fee schedule describes the split. Community Health Integration addresses unmet social needs that affect diagnosis and treatment. Principal Illness Navigation helps people with Medicare who are diagnosed with high-risk conditions, such as dementia, HIV/AIDS and cancer. The same page says the work can be done by auxiliary staff such as community health workers, care navigators and peer support specialists, as long as a billing practitioner provides the supervision.

So a navigator is not a favour a doctor's office does out of kindness. It is a defined Medicare service, billed under a provider who has seen the patient.

Now the limits, stated plainly.

Medicare doesn't automatically cover navigation. Eligibility depends on a qualifying condition or need and a provider visit. Under Original Medicare, these services carry the Part B deductible and then 20% coinsurance, and other coverage may reduce that. For many patients with supplemental coverage the cost is usually $0, and we confirm your cost before you start. The introductory call is free, while provider visits and ongoing navigation are billed separately. Our what you will pay page has the detail.

For the Part B costs themselves, see our guide to Medicare Part B. And since the line between Medicare and long-term care catches families out, Medicaid vs Medicare is worth a read before any facility conversation.

Does healthcare navigation actually help?

Honest answer: it depends what you measure, and the research is stronger for some things than others.

A 2021 overview in BMC Health Services Research looked at 11 systematic reviews of patient navigators in ambulatory care. Its authors concluded that "introducing patient navigator roles can be a strategy to improve access to healthcare services." For people with other chronic conditions, they say navigators may also improve health outcomes and lower readmission rates. Most of that evidence comes from the US, they note, and more research is needed outside cancer.

Read those words carefully. "Can be a strategy." "May also." That is a reasonable case for trying it, not a promise. We can't tell you navigation will keep your parent out of the hospital, win an appeal or reverse a denial, and nobody honest can. What it does is make sure the thing the doctor ordered gets booked, delivered and checked.

How to choose, and what to ask

Start with the trigger. A discharge with no follow-up booked, a new diagnosis, missed appointments, a denial, or a parent in another state each point to a slightly different first call. Our help-with pages are organised by those situations.

Then ask any navigator, of any kind, five things.

1. Who do you work for, and who pays you?
2. What exactly will you do, and what will you leave to me?
3. How will I know what you've done? Is there a written list?
4. What will it cost, in writing, before we begin?
5. Who do I call when you're not available?

Question four is the one that gets skipped. If anyone says "it's free" without saying who pays and when, ask again.

One more point. Your parent has to be part of this. A navigator needs your parent's permission to talk to the doctor's office, and the sooner that's set up, the easier everything after it gets. Do it while your parent can sign.
