Invoice Template for Nutritionists: Superbills, HSA/FSA, and Payment Guide
A copy-ready invoice template for nutritionists, plus how to handle superbills, CPT codes, HSA/FSA payments, and getting paid by card or ACH.
You went to school to help people eat better, not to memorize CPT codes or chase a Venmo payment from three weeks ago. Use the copy-ready nutritionist invoice template below to handle standard billing, superbills, and HSA/FSA payments, with clear translations for the required billing jargon (superbill, NPI, MNT, LMN).
What should a nutritionist invoice include?
An invoice template for nutritionists should include the practitioner's business details, credentials, client details, a unique invoice number, itemized nutrition services, rates, applicable sales tax, total due, payment terms, accepted payment methods, and any superbill fields such as NPI, CPT code, and ICD-10 diagnosis code.
A nutritionist invoice is a professional healthcare document, not a receipt scribbled at the end of a session. Clients, insurers, and HSA/FSA administrators may use it to verify services, payment status, and reimbursement details. Include:
- Your business details: legal business name, practice address, phone, email, and your EIN. An EIN (Employer Identification Number) is the business version of an SSN. Sole proprietors without employees can use an SSN, but an EIN keeps your Social Security number off client paperwork.
- Your credentials after your name: RD, RDN, CNS, CN, or LDN. This tells clients and insurers who provided care.
- Client details: legal name, address, email, and their insurance member ID if you are producing a superbill.
- A unique invoice number and issue date: a simple 2025-001, 2025-002 sequence is enough. Never reuse numbers.
- Itemized services in plain English: "Initial 60-min nutrition consult," "Custom 4-week meal plan," "Follow-up (30 min)." Not "consulting." Vague labels get rejected by insurers and generate follow-up questions from clients.
- Money math: rate × quantity, subtotal, sales tax (if applicable in your state), total due, due date, and accepted payment methods.
- A payment terms line: "Net 7," "Due on receipt," or "50% deposit at booking; balance due before session 4."

────────────────────────────────────────────────Tip: paste that block into an AI assistant with a prompt like "Turn this into a fillable Google Sheet with formulas for subtotal, tax, and total, plus a second tab for a superbill version with fields for NPI, CPT code, and ICD-10 diagnosis code." You'll get a working spreadsheet you can open in Google Sheets or Excel in under a minute. Ask for a Word doc or fillable PDF the same way.
Put your logo and brand color in the header block of your doc editor. You don't need design software. If you bill insurance, the NPI (National Provider Identifier, a 10-digit number CMS issues to healthcare providers) goes near your EIN.
Do nutritionists need superbills, CPT codes, and insurance reimbursement details?
A superbill is a detailed receipt your client submits to their insurer or HSA/FSA administrator to seek reimbursement. You still get paid at the time of service, as the client is the one filing the claim.
The CPT codes nutritionists commonly use:
- 97802: Medical Nutrition Therapy (MNT), initial assessment, individual, face-to-face
- 97803: MNT reassessment and intervention, individual follow-up
- 97804: MNT group session for two or more people
Medicare covers Medical Nutrition Therapy furnished by a Registered Dietitian or qualified nutrition professional for beneficiaries who have diabetes, renal disease, or a kidney transplant in the prior 36 months. Private insurers set their own coverage rules and often follow CMS conventions loosely.
Required superbill fields on top of a normal invoice:
- Your NPI and tax ID (EIN or SSN)
- The CPT code for each service line
- An ICD-10 diagnosis code from the referring provider (e.g., E11.9 for Type 2 diabetes without complications)
- Date of service and amount paid
- Statement that the invoice is paid in full
Scope-of-practice reality check: whether a non-RD nutritionist or health coach can bill insurance or issue a reimbursable superbill depends on your state's licensure and scope-of-practice rules. Some states restrict the title "nutritionist" or restrict who can perform MNT. Check your state's dietetics and nutrition licensing board before offering superbills, and confirm current CPT descriptors with CMS or the AMA before printing them.
How do nutritionists accept HSA and FSA payments?
HSA and FSA funds can be used for Medical Nutrition Therapy when the service treats a specific medical condition, such as diabetes, obesity, celiac disease, or hypertension, under IRS Publication 502. General wellness coaching does not qualify.
A Letter of Medical Necessity (LMN) is a short note from the client's physician stating they need nutrition care for a diagnosed condition. Some HSA/FSA administrators require one before reimbursing; others accept a superbill with an ICD-10 code. Requirements vary by plan, so tell clients to check their plan documents.
Two ways clients actually pay:
- HSA/FSA debit card at checkout. Many HSA and FSA debit cards run on standard card networks, so a card processor such as Novo Invoices can accept them. The card approves or declines based on your merchant category and the client's plan rules. If the card approves, record the payment and issue a paid receipt or superbill if the client needs one.
- Personal card plus reimbursement. If the HSA/FSA card declines, the client pays with a personal card, and you issue a superbill. They submit it for reimbursement. Mark the invoice "paid in full" with the date, because administrators may reject undated superbills.
What payment terms should nutritionists use?
Three pricing models cover most solo nutrition practices:
- Hourly. Illustrative solo-practitioner rates run roughly $100 to $250 per hour depending on credential, city, and specialty.
- Packages. Six sessions for $795, a 4-week meal plan for $200, a 12-week program for $1,500. Packages reduce how often you invoice and make it clear what the client has paid for.
- Monthly subscriptions. Illustrative monthly coaching packages run roughly $150 to $400 for ongoing sessions with async messaging.
Payment terms that actually work:
- Net 7 or Net 15 for single sessions
- 50% deposit at booking for multi-session packages, balance invoiced mid-program
- State late fees and cancellation policy on the invoice itself, not just in your intake paperwork. Example: "$50 fee for cancellations under 24 hours; $25 late fee after 14 days past due."
Example workflow for a 6-session package: send one Novo invoice for the 50% deposit ($397.50) when the client books, and a second Novo invoice for the balance ($397.50) before session 4. Or send a single invoice for $795 and mark it paid in full the day the card runs.

How can nutritionists accept card and ACH payments?
Most solo nutrition practices can cover common client payments with card and ACH, and each method fits a different situation:
- Card payments are fastest for single sessions and are the only way to run an HSA/FSA debit card.
- [ACH](/business-payments/ach) (a bank-to-bank transfer that pulls directly from the client's checking account) is cheaper for packages over about $500, where card processing fees add up.
Confirm processor fees before you price your services. Card processing at most providers runs around 2.9% + $0.30 per transaction, and ACH is typically a flat fee or roughly 1%. Check current Novo Invoices rates in your dashboard before quoting clients.
Where Novo fits. Novo Invoices lets you send unlimited invoices, accept card and ACH payments, and deposit them into your Novo business checking account. $0 monthly fees, $0 minimum balance. Novo Invoices works alongside practice-management platforms like Healthie or Practice Better by handling invoicing, card payments, ACH payments, and deposits into a Novo business checking account. Keep charting, scheduling, and clinical notes in your practice-management software, and use Novo to send invoices and keep payments in a dedicated business checking account.
One tradeoff to know: Novo does not accept cash deposits. If you take cash at in-person sessions, you'll need a workaround, such as depositing via money order or keeping a secondary cash-accepting account. Say so upfront so it doesn't surprise you later.
How do you send your first invoice as a nutritionist?
- Before the session: confirm the client's legal name, email, service booked, and whether they'll need a superbill for insurance or HSA/FSA. Ask now, not after.
- Fill the template: double-check totals, sales tax, credentials, invoice number, and due date. Sales tax rules for professional services vary by state, so confirm with your state department of revenue before adding tax to a nutrition invoice.
- Send by email or client portal with a subject line like Invoice #2025-014 from [Your Practice] — due March 21.
- Turn on automatic reminders so day-3, day-7, and day-14 past-due nudges go out without you needing to follow up manually.
- Record the payment and reconcile it in your business checking account the same week. Depositing client payments into a dedicated business account (Novo or otherwise) is the SBA's baseline recommendation for keeping business and personal finances separate.
What invoicing mistakes should nutritionists avoid?
- Depositing Venmo or Zelle payments into personal checking. At tax time you're rebuilding income from screenshots. A dedicated business account makes income easier to track and reconcile at tax time.
- Using vague line items like "consulting" or "services rendered." Insurers reject them, HSA administrators pause them, and clients ask follow-up questions.
- Leaving off the NPI or CPT code when the client asked for a superbill, forcing a reissue.
- Omitting a due date or late fee, which makes it awkward to follow up on a 45-day-old invoice.
- Forgetting to mark packages "paid in full" with the date, which stalls HSA/FSA reimbursement.
FAQ: invoicing for nutritionists
Do nutritionists charge sales tax? Sales tax rules for professional services vary by state and by what you sell (a supplement resale is treated differently than a consult). Confirm with your state's department of revenue before adding tax to a nutrition invoice.
Can clients pay a nutritionist with an HSA or FSA? Yes, when the service qualifies as Medical Nutrition Therapy for a diagnosed medical condition under IRS Publication 502. Some plan administrators request a Letter of Medical Necessity from a physician, though requirements vary by plan.
What's the difference between a receipt, an invoice, and a superbill? A receipt confirms payment. An invoice requests it. A superbill is an itemized receipt formatted for insurance or HSA/FSA reimbursement, with CPT codes, an ICD-10 diagnosis code, and the provider's NPI.
How do I invoice for a package the client paid upfront? Send one invoice for the full amount, marked "paid in full" with the payment date. Or split it: a deposit invoice at booking and a balance invoice mid-program. Either works; pick one and be consistent.
Do I need an EIN to invoice clients? While sole proprietors can invoice using an SSN, the IRS issues free EINs which are required for most business checking accounts and help keep your Social Security number off client paperwork. See our full business expenses guide for nutritionists for more on separating business finances.
Can a non-RD nutritionist issue a superbill? Sometimes. It depends on your state's licensure and scope-of-practice rules, and on what codes your credential qualifies you to bill. Check your state dietetics/nutrition board before offering superbills, and don't print CPT codes you aren't credentialed to use.
Does Novo replace Healthie or Practice Better? No. Novo provides a business checking account and invoicing tool. Keep charting, scheduling, and clinical documentation in your practice-management software. Use Novo to send invoices, accept card and ACH, and keep payments in a dedicated business checking account with $0 monthly fees.
