Do dietitians need a Good Faith Estimate? What cash-pay practices should post on their website

Do dietitians need to give Good Faith Estimates? If you practice under a state license or certification and some clients pay you directly instead of using insurance, the answer is very likely yes. Under the No Surprises Act, a federal law whose Good Faith Estimate rules have applied since January 1, 2022, those clients have a right to a written estimate of what you expect to charge. The federal rules also say your website has to tell them about that right. Below: who the rule covers, what your website needs, the deadlines, what goes in the estimate and how to check your setup. This is general information, not legal advice.

Does the Good Faith Estimate rule apply to dietitians?

Very likely, if you practice under a state license or certification. CMS, the federal agency that oversees the rule, defines a health care provider as a physician or other health care provider acting within the scope of their license or certification under state law.

Neither the rule nor CMS's guidance lists professions by name, so neither mentions dietitians specifically. What matters is your license, not your job title. Licensure differs by state, so if you aren't sure how yours works, start with our guide to how state licensure works for dietitians.

If your state doesn't license or certify dietitians, the answer is less clear, because your RD credential comes from a national body, not from state law. In that case, or if you aren't sure the rule reaches your practice, ask a healthcare attorney before deciding you're exempt.

Which clients get a Good Faith Estimate?

Clients who have no insurance, and clients who have insurance but don't plan to use it for your services. CMS calls both groups "uninsured (or self-pay)". Its guidance tells providers to ask two questions when someone books:

1. Are you enrolled in a health plan? That includes a group plan through work, an individual insurance plan, a federal health care program, or a Federal Employees Health Benefits plan.
2. If yes, do you want a claim submitted to that plan for these sessions?

A client who says no to the first question counts as uninsured. A client who has a plan but says no to the second counts as self-pay. Both get an estimate.

There's one big exception. CMS's decision tree says people enrolled in federal health care programs, such as Medicare, Medicaid and TRICARE, aren't eligible for a Good Faith Estimate, even if they don't plan to use that coverage, because those programs have other surprise billing protections. The same page says someone covered only by a short-term limited duration plan counts as uninsured.

If you're in network and a client uses their insurance with you, the self-pay estimate in this post doesn't apply to those sessions.

What does your website need to show?

A clear notice that uninsured and self-pay clients can get a Good Faith Estimate. CMS's guidance says this information must be:

• written in clear and understandable language
• prominently displayed, and easily searchable from a public search engine, on your website
• displayed in your office, and wherever scheduling or questions about cost happen
• told to clients out loud when they book or ask about cost
• available in accessible formats, and in the languages your clients speak

"Easily searchable from a public search engine" is the part many practices miss. A notice that lives only in a client portal, an intake packet or a sign on the office wall doesn't meet the website part. The simplest way to meet it is a normal public web page, written as text, which also works for screen readers. That's the same reason search engines and AI assistants need real text to understand your practice.

A simple setup that covers it

1. Create a page called "Good Faith Estimate", at an address like yoursite.com/good-faith-estimate.
2. Put the notice on it as text. CMS publishes a sample notice you can base it on. It explains the right to an estimate, the deadlines, and the right to dispute a bill that is $400 or more above the estimate.
3. Link the page from your footer, so it's reachable from every page.
4. Add one line near your fees and your booking button, for example:

Not using insurance? You have the right to a Good Faith Estimate of expected charges. Read our Good Faith Estimate notice.

For where a fees page fits in the rest of the site, see our dietitian website checklist. If you're planning a new site, put this page on your launch list. You can draft a free preview of your site to see how the other pages fit together.

If you only see clients by video, you may have no office to post a notice in. Your website and booking pages are where scheduling happens, so that's where the notice matters most.

When do you have to send the estimate?

Within 1 to 3 business days, depending on how far ahead the session is booked. From CMS's guidance and decision tree:

Three details matter most for a small practice:

• A cost question counts as a request. CMS says providers must treat any discussion or inquiry about the potential cost of services as a request for an estimate. So when someone paying cash emails "How much do your sessions cost?", the 3-business-day clock starts.
• It must be in writing. You can walk a client through it by phone, but CMS says you must also send it on paper or electronically, in the form the client prefers. An electronic copy must be one they can save and print.
• Changes mean a new estimate. If the plan changes before the session, such as more visits or a different fee, send a new estimate at least 1 business day before the session.

What goes in the estimate itself?

The estimate is a document for one client, not a price list. CMS's guidance lists what it must include. The parts that matter most for a solo practice:

• the client's name and date of birth
• a plain-language description of the main service, and its date if it's scheduled
• an itemized list of the services you expect to provide, with any applicable diagnosis codes, the expected service codes and the expected charge for each
• your name, National Provider Identifier (NPI), Tax Identification Number, and the state and location where you'll provide the services
• a list of related services the client would schedule separately, with a set disclaimer above it
• disclaimers that it's only an estimate, that you may recommend more services later, that the client can dispute a bill that's substantially higher (with where to learn how, and a statement that disputing won't affect their care), and that it isn't a contract

For a self-pay client, the "expected charge" is your cash rate, including any discount you give self-pay clients.

CMS has a sample Good Faith Estimate form. You don't have to use that exact form, as long as yours includes the required information.

Estimating a series of sessions

Nutrition care is often more than one visit. CMS lets you give one estimate for recurring services if two things are true: it spells out the expected scope, such as how often, over what timeframe and how many sessions in total, and it covers no more than 12 months.

For example, an estimate from [Your Name]'s practice might cover one initial session and five follow-up sessions over three months, with the fee for each. If care is expected to continue past 12 months, issue a new estimate and explain what changed.

Keeping it private

The estimate includes a date of birth and may include diagnosis codes. Send it through your client portal or practice-management tool, not through a website contact form. CMS says the estimate becomes part of the client's medical record and must be kept like one. You must also give a client a copy of any estimate from the last 6 years if they ask.

What happens if your bill is higher than the estimate?

The client may be able to dispute it. CMS says uninsured and self-pay clients can use the federal patient-provider dispute resolution process when a bill is at least $400 more than the expected charges on the estimate. According to CMS's guidance, the client must start the dispute within 120 calendar days of receiving the first bill with those charges, and CMS's dispute page lists a $25 administrative fee.

For a cash-pay practice, the practical lesson is simple. Estimate the plan you realistically expect, not the smallest version of it, and send a new estimate before the plan grows.

A step-by-step setup checklist

1. Confirm it applies. You practice under a state license or certification, and some clients pay without using insurance.
2. Publish the notice page as text, and link it from your footer, fees page and booking page.
3. Add the two insurance questions to your booking or intake form: are you enrolled in a health plan, and do you want to use it for these sessions?
4. Make a template from CMS's sample form, with your NPI, Tax Identification Number, location and cash fees already filled in.
5. Decide your usual scope, such as an initial session plus a set number of follow-ups, so recurring estimates are quick to write.
6. Mention it out loud, when someone books or asks about cost.
7. Send each estimate on time, in writing, in the client's preferred format.
8. File a copy with the client's record.
9. Re-issue the estimate when the number of sessions, the fees or the plan changes.

If your state has its own estimate process, CMS's guidance says following it isn't enough when it falls short of the federal requirements. If you're unsure about any step, ask a healthcare attorney or your professional liability insurer.

Common mistakes

• Treating a fee list as the estimate. Posting prices helps clients, but it doesn't replace the written, per-client estimate.
• Hiding the notice. A notice that exists only in the office, in a portal or in an intake packet misses the website requirement.
• Quoting only out loud. A phone quote is fine as a start, but CMS requires a written estimate too.
• Assuming insured clients never qualify. A client who has insurance but pays you directly is self-pay, unless they're enrolled in a federal program such as Medicare.
• Estimating one session when you expect a series. If the final bill ends up $400 or more above the estimate, the client may be able to dispute it.
• Waiting for a formal request. A question about cost from a self-pay client counts as one.

How to check your setup

Checking won't prove you're compliant, but it catches the gaps clients would notice first.

• Search for it. Search Google for your practice name plus "good faith estimate". If your notice page doesn't appear, confirm Google has indexed it. Our specialty page guide explains how to check whether a page is indexed.
• Book as a stranger. On your phone, go through booking as a self-pay client. Did you pass a link to the notice before you finished?
• Audit one real estimate against CMS's list: name, date of birth, codes, charges, NPI, Tax Identification Number, location and every required disclaimer.
