Coding for Medical Nutrition Therapy (MNT)

Medical nutrition therapy [MNT] is utilized for specific conditions (diabetes, renal failure, elevated cholesterol) whereby a nutritionist or dietician meets face to face with the patient to educate them on dietary choices, and/or cooking alternatives pertaining to their condition. National Coverage Determination for MNT [NCD 180.1] affords each patient a minimum of three hours for the first year of MNT and two hours per subsequent year with exceptions for additional hours due to a change in condition, diagnosis or treatment schedule.

Examples of appropriate utilization may include newly diagnosed diabetic patients, existing diabetic patients with a change in their condition and/or medications to control their blood glucose levels, or patients who have renal disease and have dietary restrictions.  MNT is not considered ‘incident to’ and should be only reported by the nutritionist or registered dietician that performed the services.  The allowed services per year and coverage by condition may vary from payer to payer; however, most payers do not cover MNT services for weight loss management.
