NutritionEd and the World of Nutrition and Dietetics

Meet Registered Dietitians (also known as Registered Dietitian Nutritionists), Dietetic Technicians, Registered (also called Nutrition and Dietetics Technician, Registered), Licensed Nutritionists, and Non-Licensed Nutritionists. These are highly trained, experienced health care professionals, working in diverse settings, who offer invaluable advice and education on what to eat, what to avoid, and the nutritional value of foods.

We provide an easy-to-read breakdown of the states where dietitians and nutritionists must be licensed or certified and what’s required to practice as a nutritionist or dietitian in your geographic area. Plus, we highlight the significance of Registered Dietitians in terms of government recognition and insurance reimbursement eligibility.

Insurance Reimbursement and Medicare Requirements

Federal Medicare guidelines specifically require the RD/RDN credential for medical nutrition therapy (MNT) reimbursement, making RDs the universal standard for insurance billing nationwide. However, reimbursement policies for Medicaid and private insurance vary by state and insurer. Some states permit Certified Nutrition Specialists (CNS) holding the Board Certified in Holistic Nutrition credential or Licensed Nutritionists to bill certain plans.

Frequently Asked Questions

How long does it take to become a registered dietitian?

Becoming a registered dietitian typically takes 6-7 years total. This includes 4 years for a bachelor’s degree, 1-2 years for a master’s degree (required as of January 2024), and 6-12 months for a supervised dietetic internship. The timeline can vary based on whether you attend full-time or part-time and whether you’re in a coordinated program.

What’s the difference between a registered dietitian and a nutritionist?

A registered dietitian (RD/RDN) has completed specific accredited education, 1,200 hours of supervised practice, passed a national exam, and maintains continuing education. The term “nutritionist” is less regulated and may refer to professionals with varying levels of education. RDs are eligible for Medicare reimbursement for medical nutrition therapy nationwide, while insurance coverage for other nutrition professionals varies by state and insurer. Some states allow Certified Nutrition Specialists (CNS) or other licensed nutritionists to receive reimbursement under specific conditions. Only RDs can legally practice in states requiring dietitian licensure.

Do I need a master’s degree to become an RD?

Yes, as of January 1, 2024, ACEND requires a master’s degree from an accredited program for RD eligibility. This replaces the previous bachelor’s degree minimum. If you completed your bachelor’s degree before this date, you may still qualify under earlier requirements. Check with ACEND for specific eligibility details.

How much does it cost to become a registered dietitian?

Total costs vary significantly but typically range from $60,000-$150,000. This includes bachelor’s degree tuition ($40,000-$100,000), master’s degree tuition ($20,000-$50,000), and dietetic internship costs ($5,000-$30,000). Most internships are unpaid, though some offer stipends. The CDR exam costs $200. Financial aid, scholarships, and assistantships can reduce out-of-pocket costs.

Can I become an RD with an online degree?

Yes, many ACEND-accredited programs offer online or hybrid formats for coursework. However, all students must complete in-person supervised practice hours (1,200 hours minimum) regardless of how coursework is delivered. Online programs work well for academic requirements but require local arrangements for internship rotations.

What is the starting salary for a registered dietitian?

Entry-level registered dietitians (10th percentile) earn approximately $45,630 annually according to May 2024 BLS data. Most new RDs earn between $45,000-$55,000 depending on location, work setting, and specialization. Salaries increase with experience, with the median RD earning $66,450 and experienced RDs with specializations earning $75,000-$96,850+.

Do I need a license to practice as a registered dietitian?

It depends on your state. Currently, 46 states plus Washington DC require licensure, certification, or registration for dietitians. Four states (California, Montana, Texas, Virginia) offer title protection only. Four states (Arizona, Colorado, Michigan, New Jersey) have no regulations. Even in unregulated states, the RD credential is essential for Medicare reimbursement and most employment opportunities.

What’s the difference between RD and RDN?

There is no difference—RD (Registered Dietitian) and RDN (Registered Dietitian Nutritionist) refer to the same credential issued by the Commission on Dietetic Registration. The Academy of Nutrition and Dietetics added the “nutritionist” designation in 2013 to better reflect the scope of practice. You can use either designation or both (RD/RDN) after passing the CDR exam.

Can I work as a dietitian without the RD credential?

In states requiring licensure (46 states + DC), you cannot legally practice medical nutrition therapy without being a licensed/registered dietitian. In unregulated states, you may offer general nutrition advice, but you cannot provide medical nutrition therapy under the dietitian title and may have limited insurance reimbursement options. Medicare specifically requires the RD credential for medical nutrition therapy reimbursement. Most healthcare facilities, hospitals, and schools require the RD credential for employment.

What is ACEND and why does accreditation matter?

ACEND (Accreditation Council for Education in Nutrition and Dietetics) is the Academy of Nutrition and Dietetics’ accrediting agency for education programs. Only graduates from ACEND-accredited programs are eligible to take the CDR exam and earn the RD credential. Attending a non-accredited program means you cannot become an RD, regardless of the quality of education.
