Medicare Part B covers sit-down counseling with a registered dietitian, and when you qualify it costs you nothing. Not a reduced rate, not "after the deductible." Zero. It's one of the rare Part B benefits where the deductible is waived entirely. The benefit is narrow, though: it opens for diabetes and for kidney disease as Medicare defines it, and it takes a physician's referral to start.

Who Qualifies: When Does Medicare Cover Nutrition Therapy?

So does Medicare cover nutrition therapy for everyone? No, and this is the part worth getting right. The Medical Nutrition Therapy benefit is tied to specific medical conditions, not to a general wish to eat better or lose weight.

You qualify on either of two routes: diabetes, or kidney disease as Medicare defines it. What Medicare calls renal disease here means one of three things: kidney function reduced but not enough to require dialysis or a transplant, end-stage kidney disease when you are not receiving dialysis, or the 36 months after a kidney transplant. Medicare draws that first kidney line with a number: a glomerular filtration rate, or GFR, of 15 to 59. Milder kidney disease, a GFR of 60 or above, doesn't meet the definition, though diabetes qualifies you on its own whatever your kidney function looks like.

The kidney condition is the one people misread. The benefit covers reduced kidney function, and end-stage disease when you're not on dialysis, and it covers you for up to three years after a transplant. If you're on maintenance dialysis, the rule is narrower than it usually gets described: Medicare's regulation says nutrition therapy based on a diagnosis of renal disease isn't covered for you, because your nutrition counseling is bundled into your dialysis care instead. That closes the kidney route, not the whole benefit. If you're on dialysis and you also have diabetes, none of the authorities behind this page say whether you can still be referred on the diabetes diagnosis, so ask your doctor and your plan rather than assuming the answer is no.

One more requirement: a physician has to refer you, and the referral has to note the diabetes or kidney diagnosis. You can't just book a dietitian and have Medicare pick up the tab. Here's the part people get wrong and talk themselves out of the benefit over: the rule is only that the referral may be made by a physician, not by a particular one. If the nephrologist who found your kidney disease wrote it, or the hospital doctor who diagnosed your diabetes, or a primary care doctor you've since stopped seeing, that referral counts. What has to happen is that the physician who refers you makes the referral after the diagnosis and documents it in your medical record. Physician is a defined term here, though: Medicare means a doctor of medicine or osteopathy, so a referral written by a nurse practitioner or a physician assistant does not satisfy the rule, however routinely that clinician manages your diabetes or your kidney disease. The actual counseling is done by a registered dietitian or another nutrition professional who meets Medicare's requirements.

Does Medicare Cover Nutrition Therapy for Free?

When you qualify, you pay nothing for Medical Nutrition Therapy. No coinsurance, and Medicare waives the Part B deductible for it, an unusual combination in Part B.

To see why that's a big deal, compare it to how most of Part B works. For a typical outpatient service, you first pay the annual Part B deductible ($283 in 2026), and after that you're on the hook for 20% of the Medicare-approved amount. MNT skips both. It's one of a small handful of Part B benefits where the deductible doesn't apply at all.

The practical upshot? If you've got diabetes or qualifying kidney disease and your doctor refers you, seeing a dietitian to build an eating plan around your condition is free. That's rare enough in Medicare that it's worth using if it's available to you.

How Many Hours You Get

This isn't unlimited, but it's more than a single visit. In your first calendar year, Medicare covers 3 hours of nutrition therapy. In every calendar year after that, you get up to 2 hours.

A couple of details matter here. Those first-year hours don't roll over, so if you only use one of your three hours, you don't bank the other two for next year. And the hours reset on the calendar year, not on the anniversary of your first visit.

What if your situation changes? If your doctor decides that a shift in your medical condition, your diagnosis, or your treatment plan calls for more nutrition therapy, they can write a new referral for additional hours beyond the basic amount. So the standard allotment is the floor, not a hard ceiling, when there's a medical reason to go further.

Frequently Asked Questions

Does Medicare cover a dietitian?

Only for the qualifying conditions (diabetes, or kidney disease as Medicare defines it: a GFR of 15 to 59, end-stage disease without dialysis, or the 36 months after a kidney transplant), and only with a physician's referral. Medicare pays a registered dietitian or another nutrition professional who meets its requirements, so it's worth confirming the provider bills Medicare for MNT before you book.

Is seeing a dietitian free under Medicare?

Yes, when you qualify for MNT: $0, no coinsurance, no deductible. For context, a standard Part B visit would first cost you the $283 deductible (2026) and then 20% of the approved amount; MNT waives both.

What if I'm on dialysis?

The kidney route closes. Medicare's regulation says MNT based on a diagnosis of renal disease isn't covered while you're on maintenance dialysis, because nutrition counseling is bundled into your dialysis care instead, so ask your dialysis team for it. That's narrower than "you're not eligible," though. If you also have diabetes, no authority behind this page says whether a referral on the diabetes diagnosis still works, so put the question to your doctor and your plan instead of ruling yourself out.

Do I need a referral?

Yes, and it has to come from a physician and name your diabetes or kidney diagnosis. Medicare defines physician here as a doctor of medicine or osteopathy, so a nurse practitioner or physician assistant cannot write it. It does not have to be the doctor you see most often, though: the specialist or hospital doctor who made the diagnosis can write it just as well as your regular doctor. A dietitian can't self-refer you, and Medicare won't pay without it.

How many visits do I actually get?

The benefit is measured in hours, not visits: 3 hours the first calendar year, up to 2 hours each year after, split into as many appointments as you and your dietitian decide. Unused hours don't roll over, and a documented change in your condition can earn a new referral for more.
