6 · New calendar year?
Medicare follow-up MNT is organized by calendar year - not by 12 months from the first visit.
Obtain a new MD/DO referral for the new calendar-year episode. Standard subsequent-year coverage is 2 hours.
Path A · quick workflow
Five items to check every time
Use this lane while placing or processing the order. Choose the option that matches the referral; red means stop and correct it before the handoff.
-
1
Confirm a Medicare-covered condition
The beneficiary has diabetes or qualifying renal disease:
- Chronic renal insufficiency with a GFR of 15–59 mL/min/1.73 m²;
- End-stage renal disease when the beneficiary is not receiving maintenance dialysis; or
- Up to 36 months after a successful kidney transplant.
Stop for maintenance dialysis: Medicare Part B MNT is excluded while the beneficiary is receiving dialysis covered under the ESRD benefit. -
2
Use an MD or DO as the referring physician
Federal Medicare MNT rules require a referral from a physician, defined here as a doctor of medicine or osteopathy.
APP stop: an NP, PA, CNS, or other APP cannot be the Medicare MNT referring professional under the current national rule. Route the referral to an MD/DO. -
3
State the covered diagnosis
Make diabetes or qualifying renal disease explicit on the referral. Include the most accurate ICD-10-CM code your clinic uses so the receiving team can align the claim.
Rule distinction: Medicare requires the diagnosis on the referral and the claim. The national rule does not prescribe a numeric ICD-10-CM code as a universal field on the referral document itself.
-
4
Place the referral in the medical record
The physician referral must be documented in the medical record. The national rule does not require a special Medicare referral form.
Refer to a registered dietitian nutritionist for Medicare Part B Medical Nutrition Therapy for [diabetes / qualifying renal disease].
-
5
Authenticate and date the order
The medical record order must be identifiable, signed, and dated. The referring physician’s NPI is required on the Medicare claim; a facility may also ask that it appear on the referral to prevent billing delays.
A wet signature is not the only compliant method. Follow Medicare authentication rules and your electronic record’s approved signature workflow.
Ready to refer when all five are green.
Condition · Physician · Diagnosis · Record · Authentication. Then check the four situations below.
Then ask
Do any of these four situations apply?
Turn on each situation that matches the beneficiary. The action appears immediately.
7 · More hours needed this year?
A diagnosis, medical condition, or treatment regimen changed and the change requires updated MNT.
Obtain a second physician referral that identifies the change and the need for additional MNT. The additional-hour codes are G0270/G0271.
8 · Maintenance dialysis?
The beneficiary is currently receiving maintenance dialysis under the ESRD benefit.
Do not use the separate Part B MNT benefit. Nutrition services are included in the ESRD benefit.
9 · Facility asks for extras?
The receiving site requests a face sheet, office note, labs, GFR value, NPI on the form, or its own template.
Send reasonable operational items to prevent delay, but label them as facility workflow - not a universal national Medicare referral-document requirement.
Five every time + four only when applicable = a clean Medicare MNT handoff.
Path B · education lane
Why each rule matters
Open only the detail you need. Each card separates the Medicare rule from the clinic action.
Who qualifies for Medicare Part B MNT?
Why it matters
Eligibility attaches to diabetes or renal disease as Medicare defines it - not to any diagnosis for which nutrition counseling could be clinically useful.
Clinic action
Verify diabetes or qualifying renal disease before referral. For renal disease, document the clinical basis and stop if the patient is on maintenance dialysis.
Primary source
42 CFR § 410.130 defines diabetes, renal disease, chronic renal insufficiency, and an episode of care.
Who may make the referral?
Why it matters
The MNT regulation uses a defined term: physician. In this subpart, that means an MD or DO. Medicare removed the former requirement that it be the beneficiary’s “treating physician,” but it did not expand referral authority to APPs.
Clinic action
An APP may identify the need, prepare the information, and coordinate the handoff; an MD/DO must make and authenticate the Medicare MNT referral.
Primary source
42 CFR §§ 410.130 and 410.132; CMS final policy effective January 1, 2022.
What belongs in the medical record?
Why it matters
The referral is the link between eligibility, medical necessity, and the MNT claim. Medicare requires that it be documented in the medical record.
Clinic action
State the qualifying diagnosis, place the order/referral in the record, and authenticate it under Medicare signature rules. A special national MNT form is not prescribed.
Primary source
42 CFR § 410.132(c) and Medicare Claims Processing Manual, Chapter 4, § 300.2.
How many hours are covered?
Why it matters
Unused hours do not roll over. The standard allowance is based on the calendar year in which MNT is delivered.
Clinic action
Remember 3 → 2 → +: up to 3 hours in the initial calendar year, up to 2 hours in each subsequent calendar year, and additional hours after a qualifying change with a second physician referral.
Primary source
CMS National Coverage Determination 180.1 and Claims Processing Manual, Chapter 4, §§ 300.2–300.2.2.
What starts a new episode?
Why it matters
For MNT, an episode begins with a physician referral and lasts through the end of that calendar year.
Clinic action
Secure a new physician referral for each new calendar year. If extra hours are needed during the same year, use a second referral that documents the qualifying change.
Primary source
42 CFR § 410.130 and Medicare Claims Processing Manual, Chapter 4, § 300.2.
Medicare rule or facility workflow?
Why it matters
A receiving facility can request information needed for scheduling, verification, or its own compliance process. That request does not automatically become a universal Medicare rule.
Clinic action
Meet reasonable site requirements, but teach the distinction. In the national sources reviewed, a face sheet, full office note, recent labs, a written GFR field, and a special referral form are not prescribed as universal referral-document elements.
Source boundary
This distinction is based on the fields expressly required in 42 CFR §§ 410.130–410.132 and CMS Claims Processing Manual, Chapter 4, § 300. Local Medicare Administrative Contractor and facility workflows may add operational steps.

Real-world classifier
Medicare rule, facility workflow, or not required?
Classify each item in this referral request, then use the feedback to correct the mental model.
“Please send a signed MNT order from the physician, the diabetes diagnosis, a face sheet, recent office note and labs, the physician NPI, and our referral form.”
Signed MD/DO referral
Covered diagnosis
Face sheet
Office note and recent labs
Physician NPI on the referral
Facility-specific referral form
Practical lesson: complete sensible receiving-facility requests so care is not delayed. Just do not teach every operational request as though it were a universal federal Medicare rule.
