Nutritional Counseling

Number: 0049

Policy

Aetna considers nutritional counseling a medically necessary preventive service for children and adults who are obese, and for adults who are overweight and have other cardiovascular disease risk factors (hypertension, dyslipidemia, impaired fasting glucose, or the metabolic syndrome), when it is prescribed by a physician and furnished by a provider (e.g., licensed nutritionist, registered dietician, or other qualified licensed health professionals such as nurses who are trained in nutrition) recognized under the plan.

Aetna considers nutritional counseling medically necessary for other chronic disease states in which dietary adjustment has a therapeutic role, when it is prescribed by a physician and furnished by a provider (e.g., licensed nutritionist, registered dietician, or other qualified licensed health professionals such as nurses who are trained in nutrition) recognized under the plan.

Aetna considers nutritional counseling of unproven value for conditions that have not been shown to be nutritionally related, including but not limited to asthma, attention-deficit hyperactivity disorder and chronic fatigue syndrome. 

Note: In all circumstances, the intent of this policy is to permit the nutritional counselor to function as a consultant to evaluate the member and coordinate ongoing care with the referring physician.

Background

Medical nutrition therapy provided by a registered dietitian involves the assessment of the person’s overall nutritional status followed by the assignment of individualized diet, counseling, and/or specialized nutrition therapies to treat a chronic illness or condition.  Medical nutrition therapy has been integrated into the treatment guidelines for a number of chronic diseases, including

  1. Cardiovascular disease,
  2. Diabetes mellitus,
  3. Hypertension,
  4. Kidney disease,
  5. Eating disorders,
  6. Gastrointestinal disorders,
  7. Seizures (i.e., ketogenic diet), and other conditions (e.g., chronic obstructive pulmonary disease) based on the efficacy of diet and lifestyle on the treatment of these diseased states. 

Registered dietitians, working in a coordinated, multi-disciplinary team effort with the primary care physician, take into account a person’s food intake, physical activity, course of any medical therapy including medications and other treatments, individual preferences, and other factors.

The U.S. Preventive Services Task Force (USPSTF, 2012) recommends recommends screening all adults for obesity. The USPSTF recommends that clinicians should offer or refer patients with a body mass index (BMI) of 30 kg/m2 or higher to intensive, multicomponent behavioral interventions. The USPSTF (2010) recommends that clinicians screen children aged 6 years and older for obesity and offer them or refer them to comprehensive, intensive behavioral intervention to promote improvement in weight status. 

The USPSTF (2014) recomends offering or referring adults who are overweight or obese and have additional cardiovascular disease (CVD) risk factors to intensive behavioral counseling interventions to promote a healthful diet and physical activity for CVD prevention. This recommendation applies to adults aged 18 years or older in primary care settings who are overweight or obese and have known CVD risk factors (hypertension, dyslipidemia, impaired fasting glucose, or the metabolic syndrome). In the studies reviewed by the USPSTF, the vast majority of participants had a BMI greater than 25 kg/m2.

De Luis et al (2009) assessed the utility of a hypo-caloric diet with Optisource versus nutritional counseling in obese patients with an indication of replacement surgery for degenerative osteoarthritis.  A total of 36 patients were randomized into 2 groups:

  1. diet 1 with lunch and dinner substituted by 2 Optisource [1,109.3 kcal/day, 166.4 g of carbohydrates (60 %), 63 g of proteins (23 %), 21.3 g of lipids (17 %)] and
  2. diet 2 with nutritional counseling with a decrease of 500 cal/day from the previous dietary intake.

Before and 3 months after treatment, a nutritional and biochemical study was performed. A total of 19 patients were randomized in group 1 and 17 patients in group 2. All patients in group 1 and 14 patients in group 2 finished the study. Weight loss was higher in group 1 than group 2 (7.7 [4.7] versus 3.92 [3.32] kg; p = 0.05), with a significant decrease of homeostasis model assessment (HOMA) and diastolic blood pressure in group 1. Decreases of body mass index (-2.9 [1.8] versus -1.4 [0.9]; p = 0.05), fat mass (-3.8 [3.4] versus -2.3 [1.7] kg; p = 0.005) and HOMA (-2.0 [2.2] versus -0.4 [1.82]; p = 0.05) were higher in group 1 than group 2.  The authors concluded that obese patients with chronic osteoarthritis treated with a mixed diet supplemented with a commercial hypo-caloric formula improved weight, fat mass and HOMA in a better way than patients treated with a dietary counseling alone.

There is a lack of reliable evidence for nutritional interventions as a treatment for asthma.  Ahnert and colleagues (2010) employed relevant data bases to collect and evaluate guidelines, meta-analyses, and reviews as well as primary studies dealing with asthma therapy for children and adolescents.  Treatment approaches whose effectiveness with regard to bronchial asthma was empirically verified (i.e., evidence-based) were identified (medical and diagnostic procedures as well as drug trials were excluded from the analysis).  A total of 152 methodically sound studies referring to asthma treatment of children and adolescents were selected.  Strong evidence was found for patient education, parent education, exercise therapy, inhalation, and tobacco withdrawal.  Nutritional counseling and avoidance of allergens showed limited evidence.  Breathing exercises, climate therapy, clinical social work (legal and social counseling services, vocational re-integration counseling, aftercare), integration counseling, psychotherapy, and relaxation techniques showed inconsistent evidence.  No evidence was found for alternative medicine.

Su and colleagues (2016) stated that a growing number of studies and reviews have documented the impact of telemedicine on diabetes management.  However, no meta-analysis has assessed whether including nutritional counseling as part of a telemedicine program has a significant impact on diabetes outcomes or what kind of nutritional counseling is most effective.  Original research articles examining the effect of telemedicine interventions on HbA1c levels in patients with Type 1 or Type 2 diabetes were included in this study.  A literature search was performed and 92 studies were retained for analysis.  These researchers examined stratified results by differentiating interventions using no nutritional counseling from those that used nutritional counseling.  They further compared between nutritional counseling administered via short message systems (SMS) such as e-mail and text messages, and nutritional counseling administered via telephone or video-conference.  Telemedicine programs that include a nutritional component showed similar effect in diabetes management as those programs that do not.  Furthermore, subgroup analysis revealed that nutritional intervention via SMS such as e-mail and text messages is at least as equally effective in reducing HbA1c when compared to personal nutritional counseling with a practitioner over video-conference or telephone.  The authors concluded that the inclusion of nutritional counseling as part of a telemedicine program did not make a significant difference to diabetes outcomes.  Incorporating nutritional counseling into telemedicine programs via SMS was at least as effective as counseling via telephone or video-conference.
