Your Credentialing Roadmap
Your Dietitian Nutritionist Credentialing Roadmap
Starting the credentialing process can feel overwhelming — especially with different licenses, payer rules, and state requirements. This page gives you a clear, simple path so you know exactly where to begin.
Whether you are a dietitian, nutritionist, CNS, or CNS candidate, follow the steps below to determine the best route for insurance credentialing and practice setup.
1. Identify Your Provider Type
Credentialing requirements and application pathways vary heavily depending on your specific board credentials, medical specialties, and state laws. Please choose the option that best fits you or your expanding group practice:
Nutrition & Dietetics Professionals: Registered Dietitian (RDN), State-Licensed Nutritionist (LN, LDN, CN, etc.), Certified Nutrition Specialist (CNS), or MS Nutrition Graduates.
Medical Providers: Medical Doctor (MD), Doctor of Osteopathic Medicine (DO), Physician Assistant (PA), or Nurse Practitioner (NP, ARNP).
Behavioral Health Providers: Licensed Clinical Social Worker (LCSW), Licensed Professional Counselor (LPC/LMHC), Licensed Marriage and Family Therapist (LMFT), or Clinical Psychologist (PsyD/PhD).
Not sure which one applies? Book a free call and we’ll help you check.
2. Review State Licensure Rules
Your state determines:
what title you can use
whether you can provide MNT
which insurers allow non-RDN providers
whether CNS/CN/LN can credential independently
Holistika provides state-by-state guidance to confirm your eligibility before we begin any applications.
3. Choose Your Credentialing Path
Once your license and state allow it, select the route that matches your goals:
Solo Provider
Start credentialing under your own business or personal NPI.
Group Practice
Credential multiple clinicians under a single TIN and expand your team.
Transitioning from Berry, Fay, Vida, or Agency-Based Work
If you’re currently working under an agency’s contracts, start with our
“Why Separate Credentialing Matters” page to learn why independent contracting gives you more freedom, income, and long-term stability.

What Our Clients Say
-
![Makayla Davis, MS, CNS, LDN, CN, NASM-CPT - CEO at Soul of Nutrition and Fitness LLC]()
“Maria is awesome to work with. She is so nice and has a great work ethic. She quickly got to work on my case and kept me well-informed at every step of the process. She always promptly answered all of my questions. I wouldn't have been able to do it without her. Now I am credentialed with several major insurance companies including United Health Care, Aetna, and Cigna. I highly recommend working with Maria!”

![Olga Arnold, CNS Founder, Olga’s Nutrition, LLC]()
"Working with Maria to get set up for insurance as a Certified Nutritional Specialist (CNS) has been a total game-changer for my practice. Honestly, the whole process felt overwhelming at first—I didn’t know where to begin or what was even possible. But Maria made it all feel doable and clear every step of the way. She truly went above and beyond. She’s incredibly knowledgeable, explains things in a way that makes sense, and—most importantly—she’s always available. Anytime I had a question (and I had a lot), she was right there with thoughtful, straightforward guidance. I could not have done this without her. Thanks to Maria, I now feel confident offering insurance-based services that align with how I practice functional nutrition. If you’re feeling stuck or unsure about how to navigate insurance, Maria is absolutely the person you want on your team."

![Natallia Lambrecht, MS, CNS, LDN - New Hampshire]()
"The process of credentialing was very easy for me because Maria did all the “heavy lifting”. She was always prompt with updates and answered all questions that I had. The video meetings she hosted were very informative for a newbie like me. Maria is generous with her time and always happy to help. She is my insurance mentor for sure! I wouldn’t be able to do it without her. My experience has been great! "

![Olena May, MS, CNS, LDN - Functional Nutritionist in Florida]()
"I can’t recommend Izzie’s credentialing services enough! I spent months trying to navigate the process on my own — it was frustrating, confusing, and full of mistakes. Working with Izzie was worth every penny. She guided me through every step, answered all my questions, and successfully got me credentialed with all major commercial insurances. We’re now working on Medicaid, and I only wish I had hired her sooner instead of wasting so many hours on the phone and dealing with denials!"
