Nutrition counseling can be a critical component of good health care, especially for people recently diagnosed with diabetes or high cholesterol who need to adhere to a specific diet. People also meet with nutritionists for help developing a healthy vegetarian or vegan diet, developing an eating plan to lose weight or gain muscle, or improving their sports performance by changing their diet. Nutritionists may be covered by health insurance depending on your reason for meeting with them. Nutrition counseling is more likely to be covered if it is part of a doctor-prescribed treatment for a particular medical condition, such as diabetes, obesity, high blood pressure or coronary heart disease. For example, Medicare covers medical nutrition therapy services only for people diagnosed with diabetes or kidney disease, as long as they get a referral from their doctor. Also, insurance providers more often cover nutrition visits if the patient has been referred to a registered dietitian within the carrier’s network of providers. Insurance plans vary greatly, so research your benefits before visiting a nutritionist.
