Using the correct CPT codes ensures you get reimbursed while helping patients access important nutrition services.

Here’s a straightforward look at what MNT CPT codes are and how to use them effectively.

What Are Medical Nutrition Therapy (MNT) CPT Codes?

CPT (Current Procedural Terminology) codes are universal codes that describe medical procedures. Developed by the American Medical Association (AMA), these codes make it easier for healthcare providers to bill insurance companies for services. For MNT, the main CPT codes capture the work done by dietitians to assess and guide patients on their nutrition for better health outcomes.
