How to Write an MNT Note That Gets Paid

The MNT documentation guide for RDs who bill insurance: ADIME or SOAP, PES, time and units, medical necessity, signatures, and what payers check.

An MNT note gets paid when it proves three things: the patient needed medical nutrition therapy, you delivered it, and the time you billed actually happened. Everything else, including the format (ADIME or SOAP), the software and the length, is up to you. This guide covers what a paid note contains, how to handle time and units, medical-necessity wording, signatures and late entries, and what payers check when they ask for your records.

It's written for dietitians in private practice who bill insurance. It isn't legal advice, and payers vary. When a rule here is payer-specific, we say so and point to the source.

The paid-note checklist

Every MNT note should let a reviewer answer these questions without calling you.

The visit

Why MNT was needed

What you did

What happens next

Authentication

If your note answers all of these, the format barely matters. For complete examples, see the ADIME note example (template plus an initial and a follow-up visit) and our SOAP note templates.

Format: ADIME or SOAP

Payers accept both. The choice depends on who reads your notes.

The one rule: pick one and use it for every visit. Switching formats between visits makes a chart harder to review and hides progress over time. We compare the two with the same visit written both ways in ADIME vs. SOAP notes.

PES statements: the bridge between the diet and the diagnosis

The PES statement (Problem related to Etiology as evidenced by Signs/symptoms) explains why this patient needs MNT, not just general healthy-eating advice. A strong PES:

It should also fit the medical diagnosis on the claim. A PES about fiber intake next to an E78 hyperlipidemia code makes sense. The same PES next to a lone Z71.3 counseling code gives the reviewer nothing to connect it to. We have 25 PES examples by condition and a free PES statement builder. For official terms, use the Academy's freely available NCP terms or eNCPT, not the made-up labels that circulate online.

Time, units and start/stop times

97802 and 97803 are timed codes in 15-minute units, and 97804 (group) is in 30-minute units. The units on the claim have to match the time in the note. This is the most common mismatch a reviewer finds and the easiest one to prevent.

Face-to-face minutes Units of 97802 / 97803
0–7 0 (not billable as a timed unit)
8–22 1
23–37 2
38–52 3
53–67 4
68–82 5

The table follows the midpoint convention (a unit counts once you pass half of it). Most payers use it for MNT, but some commercial plans set their own unit rules or per-visit caps. The details, including edge cases, are in the 8-minute rule for dietitians, and the units calculator does the math for you.

To get this right:

Medical necessity: say why, not just what

"Medical necessity" means the note shows that this visit was reasonable and needed for this patient's condition. Medicare applies this strictly to MNT. The benefit covers diabetes and renal disease with a physician referral, and a Medicare MNT claim without one of those diagnoses is denied as not reasonable and necessary (Ch. 4 §300.5; NCD 180.1). Commercial plans write their own medical policies, and many list covered diagnoses by code.

Wording that supports necessity:

Wording that weakens it: "discussed healthy eating," "patient doing well, continue plan," and assessment text copied word for word from the last visit. More examples, and how to keep the story consistent across a series of visits, are in charting for medical necessity.

Signatures, AI scribes and late entries

Sign every note. Medicare reviewers look for "signed and dated medical documentation," and CMS may deny claims when entries don't meet signature requirements (MLN905364). Use your electronic signature with credentials. Don't leave drafts unsigned.

AI scribes are fine if you sign. The same CMS fact sheet says: "If you use a scribe, including artificial intelligence technology, sign the entry to authenticate the documents and the care you provided." You don't have to note who or what transcribed the entry. Your signature is what counts, so read an AI draft as if you'd typed it yourself. Check the times, codes, the patient's own words and anything the model may have filled in. Our AI charting guide covers how to review a generated note.

Late entries and corrections are allowed if they're labeled. CMS expects services to be documented when they're provided. When a note has to be amended, corrected or entered late, "the date and author of any amendment, correction or delayed entry should be identifiable," and the change should be "clearly and permanently denoted" (Program Integrity Manual, Ch. 3 §3.3.2.5). In practice:

If you missed a signature, CMS accepts a signed attestation from the note's author for most medical documentation (not for orders).

Records requests: what payers check

Sooner or later a payer will ask for notes, before payment or years after. What they check is predictable: that the patient was eligible, that there was a referral if required, that the diagnosis supports the code, that time supports the units, that the note shows necessity, and that it's signed. How this varies by payer (Medicare, Medicare Advantage, commercial) is in payer documentation requirements. When a request arrives, follow your payer requested your chart notes: what to send, what not to send, and the deadlines.

Being paid now doesn't mean the payer can't take the money back later. The full approach to documenting so a post-payment review finds nothing to recoup is in how to audit-proof your nutrition claims. If a claim is already denied for necessity, see the CO-50 denial and how to appeal a denied nutrition claim.

Templates and tools

The short version

A note that gets paid shows why the patient needed MNT (a dated finding tied to a covered diagnosis), what you did (a specific intervention and measurable goals), how long it took (start and stop times that match the units), and who did it (signed, with credentials). Write it the same way every visit, label any late entry, and never bill more than the note shows.

Frequently asked questions

What documentation is required for medical nutrition therapy?

Each MNT note should show the date of service, face-to-face time that supports the units billed, the medical diagnosis that justifies MNT, your nutrition assessment and nutrition diagnosis, what you did during the visit, measurable goals and a follow-up plan, and your signature with credentials and date. Medicare also requires a physician referral for diabetes or renal disease. Commercial plans add their own rules, so check the plan's policy.

Do insurance companies require ADIME or SOAP format?

No. Payers don't require a format. They check whether the content supports the claim. ADIME fits the Nutrition Care Process and SOAP is easier for referring physicians to read. Pick one, build a template, and use it for every visit.

How do I document time for 97802 and 97803?

Record start and stop times, or total face-to-face minutes, in every note. The units on the claim have to match: under the midpoint convention for 15-minute codes, 8 to 22 minutes is 1 unit, 23 to 37 is 2, 38 to 52 is 3, and 53 to 67 is 4. Time the patient spent on intake forms without you doesn't count.

Can I use an AI scribe for MNT notes?

Yes, as long as you review the note and sign it. CMS's signature guidance says that if you use a scribe, including artificial intelligence technology, you sign the entry to authenticate the documentation and the care. Once you sign an AI draft, it's your note, so check the times, codes and findings against what actually happened.

What if I forgot to document something after the visit?

Add a clearly labeled late entry or addendum with the current date and your name. Don't edit the original note so it looks like it was written at the visit. CMS expects the date and author of any amendment, correction or delayed entry to be identifiable.
