If you have Medicare, MNT is covered if you have Type 1 or Type 2 diabetes, obesity, or non-dialysis kidney disease. You will need a referral from a registered Medicare provider. Many other health insurances cover MNT based on your diagnosis. For non-diabetes nutrition-related conditions, such as high cholesterol, renal disease, celiac disease, call your insurance company and ask if your plan covers outpatient nutrition education or medical nutrition therapy.
