What is the difference between a dietitian and a nutritionist?
The terms dietitian and nutritionist are often used interchangeably. However, there are actually key credential differences between dietitians and nutritionists that are important to keep in mind when seeking a nutrition professional.
A registered dietitian (RD) or registered dietitian nutritionist (RDN) has earned at least a graduate degree from an accredited program, completed a supervised practice program, passed the Commission on Dietetic Registration exam, and continues their education regularly. The RD and RDN credentials are regulated by the Academy of Nutrition and Dietetics, the largest nutrition-related organization in the country. Only professionals who meet their standards can call themselves an RD or RDN and enjoy privileges like billing insurance. Additionally, RDs and RDNs can get board certifications in specialized areas such as gerontological nutrition (CSG), sports dietetics (CSSD), pediatric nutrition (CSP), renal nutrition (CSR), or oncology nutrition (CSO). They also need state licensure, which usually aligns with national requirements.
In contrast, the title "nutritionist" doesn't require any formal education or credentials; anyone can use the title of nutritionist, including those with very limited or no formal training in nutrition. Although there are certification programs that are marketed toward those interested in nutrition counseling, the rigor and academic requirements for such programs varies greatly. These important differences between dietitians and nutritionists are thus very important to consider when choosing the right nutrition professional for your needs. To be listed in the HealthProfs directory, Nutritionists must have a minimum of a Masters Degree in a relevant field.

When should I see a dietitian or a nutritionist?
Clients seek nutritional support from dietitians and nutritionists for various reasons, ranging from medical conditions to lifestyle concerns like weight loss or dietary requirements; however, it's always important to find a professional who is a good fit for you. Consider factors such as insurance coverage, your specific medical or dietary concerns, and the availability of professionals near you to determine whether a dietitian or nutritionist may be a better fit.
Generally, nutritionists are not covered by insurance, whereas Registered Dietitians (RDs) often are, especially for those with medical conditions. If you have a chronic medical condition like cancer or kidney disease, you might want to seek out an RD with specialized expertise, such as a Board Certified Specialist in Oncology Nutrition (CSO) or a Board Certified Specialist in Renal Nutrition (CSR). These credentials indicate advanced education and a commitment to ongoing learning within a specific area. Additionally, consider the availability of professionals in your area and their openness to telehealth sessions. While the field of dietetics is growing, there may not always be a wide selection of professionals, especially in rural areas. In such cases, focusing on the experience and expertise of the nutrition professional can be more important than their specific credentials.

Do I need a referral to see a dietitian or a nutritionist?
A referral is not required to see a dietitian or nutritionist, and many individuals independently seek nutritional support without prior medical advice. However, for a nutrition service to be covered by insurance, a referral from a primary care physician or another medical professional may be necessary. In such cases, a referral is typically made for those who have been formally diagnosed with a medical condition requiring nutrition counseling, such as diabetes or hypertension. If insurance coverage is critical to a client's ability to see a dietitian, they should contact their insurance provider to determine if a referral is needed for nutritional counseling and to understand any potential co-pays or coverage limits that may apply in their individual circumstance.
How much does it cost to see a dietitian or a nutritionist?
The cost of seeing a dietitian or nutritionist depends on a number of variables, including their location, their specialty, whether they take insurance, and the professional's experience and training. On average, the cost of out-of-pocket sessions with a dietitian or nutritionist within the United States ranges from $50-$150. In some cases, nutrition professionals will require a longer initial evaluation session that will cost more than ongoing follow-up sessions. Dietitians and nutritionists may also offer packages for clients interested in longer-term nutritional support; in such cases, they may charge monthly or other periodic fees for more comprehensive services, such as a combination of nutrition sessions and out-of-session coaching support. If nutrition services are covered by a client's insurance plan and they are eligible for coverage based on any referral requirements, the out-of-pocket cost of seeing a dietitian may be completely covered or significantly reduced.
Are consultations with a dietitian or nutritionist covered by insurance?
If your insurance covers nutrition services, the cost is usually lower than paying out-of-pocket. However, insurance coverage can vary based on factors like your specific plan details, whether you choose an in-network or out-of-network provider, and whether you have a referral for nutrition services based on a medical diagnosis.
Coverage also depends on the type of nutrition service. Typically, insurance plans only cover services provided by a licensed Registered Dietitian (RD) and do not cover those offered by nutritionists or nutrition coaches without the RD credential. If nutrition services are not covered by your insurance, some dietitians and nutritionists may offer sliding scale rates or lower-cost services for clients who cannot afford their full fee. However, these spots are often limited and may not always be available.
