Nutrition and Dietitian Billing Services
Dietitian billing depends on a short list of codes and a long list of coverage rules. Medical nutrition therapy is a recognized service, but plans pay for it only for certain conditions, certain visit counts, and sometimes only with a referral. Many registered dietitians also run cash practices, which adds to the confusion.
Westmont connects registered dietitians and nutrition practices with vetted billing experts who understand this mix. A good dietitian billing company starts with benefit checks, matches each visit to a covered diagnosis, and tracks visit limits so patients are not surprised. That helps clinics get paid for covered visits and keeps cash and insurance accounts clean.

Billing challenges in nutrition counseling
Medicare's narrow coverage. Medicare generally covers medical nutrition therapy for people with diabetes or kidney disease, and after a kidney transplant, with a referral from a treating physician. Obesity alone usually does not qualify. Billers check eligibility before the first visit.
Referral requirements. Medicare and some other plans want a written referral. Billers collect it up front and keep it in the chart.
Annual hour limits. Medicare sets a limit on hours in the first year and in later years, with more time possible only when something changes. Billers track hours so a visit is not scheduled that will be denied.
Diagnosis requirements. Many commercial plans only pay when the diagnosis matches a covered list, and some plans deny nutrition for general wellness. Billers link visits to the supported diagnosis.
Credentialing. Dietitians must be enrolled and credentialed with each plan to be paid, and requirements vary. Billers manage applications and renewals.
Time-based units. Individual visits are billed in 15-minute units, so notes must record time clearly. Billers confirm that units match the record.
Cash and insurance together. Many practices offer both. Billers separate the two ledgers so patient statements and refunds stay correct.

Frequently asked questions
Does insurance cover dietitian visits?
Often only in specific situations. Medicare generally covers medical nutrition therapy for diabetes and kidney disease with a physician referral, and many commercial plans cover nutrition counseling for certain diagnoses or as preventive care. Coverage varies widely, so verify benefits before the first visit.
What is the difference between 97802 and 97803?
97802 is for the initial assessment and intervention, and 97803 is for follow-up visits. Both are individual services billed in 15-minute units. 97804 is for groups. Choose the code that matches the visit, and keep time documented so the units are supported.
Do I need a referral to bill Medicare for nutrition therapy?
Medicare generally requires a referral from the treating physician for medical nutrition therapy. The referral should be in the record before services begin. Rules can change, so check current Medicare guidance and your contractor's instructions.
Can a dietitian bill for telehealth visits?
Many plans cover nutrition visits by telehealth, and Medicare has allowed medical nutrition therapy by telehealth, but telehealth rules have changed over time. Check the current-year Medicare policy and each commercial payer's rules before relying on telehealth for billing.
Is it worth billing insurance for a small practice?
It depends on your patient mix. Insurance can widen access for patients who qualify, but it adds credentialing and paperwork. We can match you with billing experts who help you weigh this and handle the work if you choose to bill.
