Certain Cigna Companies and/or lines ofbusiness only provide utilization review services to clients and do not make coverage determinations. References to standard benefit planlanguage and coverage determinations do not apply to those clients. Coverage Policies are intended to provide guidance in interpretingcertain standard benefit plans administered by Cigna Companies. Please note, the terms of a customer’s particular benefit plan document[Group Service Agreement, Evidence of Coverage, Certificate of Coverage, Summary Plan Description (SPD) or similar plan document] maydiffer significantly from the standard benefit plans upon which these Coverage Policies are based. For example, a customer’s benefit plandocument may contain a specific exclusion related to a topic addressed in a Coverage Policy. In the event of a conflict, a customer’s benefitplan document always supersedes the information in the Coverage Policies. In the absence of a controlling federal or state coveragemandate, benefits are ultimately determined by the terms of the applicable benefit plan document. Coverage determinations in each specificinstance require consideration of 1) the terms of the applicable benefit plan document in effect on the date of service; 2) any applicablelaws/regulations; 3) any relevant collateral source materials including Coverage Policies and; 4) the specific facts of the particularsituation. Coverage Policies relate exclusively to the administration of health benefit plans. Coverage Policies are not recommendations forPage 1 of 84Medical Coverage Policy: 0051

BMI is an objective measurementand is currently considered the most reproducible measurement of total body fat. In adults, excess body weight(EBW) is defined as the amount of weight that is in excess of the ideal body weight (IBW), or a BMI 25 kg/m2The National Heart, Lung and Blood Institute (NHLBI) (1998) clinical guidelines recommended that the BMIshould be used to classify overweight and obesity and to estimate relative risk for disease compared to normalweight The NHLBI (1998) defined the following classifications based on BMI:ClassificationBMIUnderweight 18.5 kg/m2Normal weight18.5–24.9 kg/m2Overweight25.0–29.9 kg/m2Obesity (Class 1)30.0–34.9 kg/m2Obesity (Class 2)35.0–39.9 kg/m2Extreme Obesity (Class 3) 40 kg/m2BMI is a direct calculation based on height and weight, regardless of gender:BMI Page 7 of 84Medical Coverage Policy: 0051weight (kg )height (m 2 ) weight (lb) x 7032 height (in) OR

Clinically severe or morbid obesity is defined as a BMI 40 or a BMI of 35–39.9 with comorbid conditions.Another group of individuals who have been identified are the super-obese. Super-obesity has been defined inthe literature as a BMI 50. Comorbidities of morbid obesity that may be considered include any of the following: mechanical arthropathy (weight-related degenerative joint disease)type 2 diabetesclinically unmanageable hypertension (systolic blood pressure at least 140 mm Hg or diastolic bloodpressure 90 mm Hg or greater, or if individual is taking antihypertensive agents)hyperlipidemiacoronary artery diseaselower extremity lymphatic or venous obstructionsevere obstructive sleep apneaobesity-related pulmonary hypertensionOther severe obesity-related co-morbidities including obesity-hypoventilation syndrome (OHS), Pickwickiansyndrome (a combination of obstructive sleep apnea [OSA] and OHS), nonalcoholic fatty liver disease (NAFLD)or nonalcoholic steatohepatitis (NASH), pseudotumor cerebri, gastroesophageal reflux disease (GERD), asthma,venous stasis disease, severe urinary incontinence, or considerably impaired quality of life, may also beconsidered for bariatric surgical intervention (Mechanick, et al., 2013).Strategies for Weight LossTreatment of obesity is generally described as a two-part process: 1) assessment, including BMI measurementand risk factor identification; and 2) treatment/management. Obesity management includes primary weight loss,prevention of weight regain and the management of associated risk. During the assessment phase, the individualneeds to be prepared for the comprehensive nature of the program, including realistic timelines and goals.Gener
