The short answer
Original Medicare (Part B) covers medical nutrition therapy (MNT) with a registered dietitian for three groups of beneficiaries, and nobody else:
- People with diabetes
- People with chronic kidney disease who are not on maintenance dialysis
- People who had a kidney transplant in the last 36 months
The benefit is set by NCD 180.1 and the regulations at 42 CFR 410.130–410.134. Medicare.gov summarizes it for patients: a doctor must refer you, you get 3 hours in the first calendar year and up to 2 hours of follow-up each year after, and you pay nothing if you qualify.
Everything else a dietitian sees in private practice (prediabetes, high cholesterol, IBS, PCOS, weight management on its own) is not covered by Original Medicare's MNT benefit. That is the single most common surprise for new Medicare providers.
What the policy actually says
Diagnoses. The regulation defines diabetes as a condition of abnormal glucose metabolism, and renal disease as chronic renal insufficiency (a GFR of 15–59 ml/min/1.73m², not severe enough for dialysis or transplant), end-stage renal disease when the patient is not receiving dialysis, or the 36 months after a kidney transplant. MNT based on renal disease is not covered for beneficiaries on maintenance dialysis; their nutrition care is part of the dialysis benefit.
Referral. Medicare pays for MNT only when the beneficiary is referred by a physician, and the regulation defines the treating physician as a doctor of medicine or osteopathy. The referring physician documents the diagnosis in the medical record. On the claim, the referring provider's name and NPI go in item 17/17b of the CMS-1500 (or the electronic equivalent). A missing or invalid referring NPI is one of the most common reasons a Medicare MNT claim comes back. See our guide to physician referrals for dietitians.
Who can bill. A registered dietitian or nutrition professional who meets 42 CFR 410.134 and is enrolled in Medicare. If you are not enrolled yet, start with Medicare enrollment for dietitians.
Hours, not visits: the 3 + 2 rule
Medicare MNT is counted in hours. That matters because the CPT codes are billed in 15-minute units:
| Year | Hours covered | 15-minute units |
|---|---|---|
| First calendar year of MNT | 3 hours | 12 units |
| Each following calendar year | 2 hours | 8 units |
| Change in diagnosis, condition or treatment | Additional hours with a new physician referral | Billed with G0270 (individual) or G0271 (group) |
Hours do not roll over: Medicare.gov notes that unused initial hours can't be carried into the next calendar year. The NCD also allows MNT and diabetes self-management training (DSMT) in the same episode of care, as long as they are not billed on the same date of service.
Once the hours are used, Medicare returns claims with a benefit-maximum reason (CARC 119). The fix is not an appeal; it is a second referral for a documented change, billed with G0270 or G0271. Our page on CO-119 benefit limits covers how to read that denial.
Preventive or medical benefit?
For Medicare, MNT is a Part B preventive service with no deductible or coinsurance for a qualifying beneficiary. The diagnosis still has to be diabetes or kidney disease: Z71.3 (dietary counseling) on its own is not a covered MNT diagnosis for Medicare, and neither is a BMI code. Lead with the diabetes (E08–E13) or CKD (N18.x) code the referral names. See Z71.3 claim denials for what happens when it is sent as the only diagnosis.
Weight loss is a different benefit. Medicare covers intensive behavioral therapy for obesity (BMI of 30 or more) under NCD 210.12, but it must be furnished by a qualified primary care physician or other primary care practitioner in a primary care setting. A dietitian cannot bill it under her own NPI.
Plan types that change the answer
- Medicare Advantage (Part C). MA plans must cover what Original Medicare covers, and many add their own rules: network, referral, prior authorization, sometimes broader nutrition benefits. Bill the MA plan, not Medicare. See Medicare Advantage billing for dietitians.
- Medigap. A supplement pays after Original Medicare; it does not create MNT coverage for diagnoses Medicare excludes.
- Dual eligibles (Medicare + Medicaid). Medicare pays first for covered MNT. Medicaid rules for anything beyond that vary by state; see Medicaid nutrition counseling.
Telehealth in 2026
97802, 97803 and G0270 can be furnished as Medicare telehealth. What is temporary is where the patient can be. The CMS Telehealth FAQ updated February 26, 2026 says that through December 31, 2027 beneficiaries can receive Medicare telehealth anywhere in the United States, including at home; starting January 1, 2028, most non-behavioral telehealth goes back to requiring a medical facility in a rural area unless the law changes again.
The same FAQ tells practitioners to use POS 10 when the patient is at home and POS 02 when they are somewhere else. Check your Medicare Administrative Contractor's current instructions on modifier 95 before you bill. For the full picture, read telehealth billing for dietitians.
How to verify a Medicare patient's MNT benefit
Before the first visit:
- Confirm the plan. Is this Original Medicare or a Medicare Advantage plan? The card and an eligibility check tell you. MA means you bill the plan under its rules.
- Confirm the diagnosis and the referral. Is there a diabetes or CKD diagnosis, is the patient on dialysis, and do you have a referral signed by an MD or DO with their NPI?
- Ask how many MNT hours were already used this calendar year. Hours used with another dietitian count against the same limit, so ask the patient whether they have seen a dietitian this year, and call the MAC's provider line if you are unsure.
- Plan the year. Divide the 3 (or 2) hours across visits deliberately; a 60-minute intake uses a third of the first-year benefit.
- If you expect Medicare not to pay (a non-covered diagnosis, or hours past the limit), tell the patient before the service and use an Advance Beneficiary Notice (ABN) where CMS's ABN rules call for one.
For dietitians: codes and claim tips
- 97802 for the initial assessment, 97803 for every follow-up (re-assessment and intervention), 97804 for groups. Medicare uses 97802 once, for the initial assessment; see CPT 97802 and CPT 97803.
- Units come from this visit's documented face-to-face minutes. Use the MNT units calculator or read the 8-minute rule for dietitians.
- Diagnosis first: the diabetes or CKD code the referral names. Add a BMI code only as a secondary diagnosis when it is documented.
- Referring provider NPI in item 17b. It must be the physician who referred.
- Rendering NPI is yours, as the dietitian who saw the patient and signed the note.
