Bariatric Surgery Criteria

Program Rationale

Obesity in the United States is increasing affecting 30-36% of the adult population and 17% of youth. 1 2 Obesity increases with advancing age for both sexes in the United States. 1 Racial and ethnic differences are more strongly seen in women than in men. 2 3 Among non-Hispanic black and Mexican-American men, those with higher incomes are more likely to be obese than those with low incomes. On the other hand higher income women are less likely to be obese than low income women. Among men there is no significant relationship between obesity and education. The converse is true for women in that those with college degrees are less likely to be obese compared to less educated women. Obesity overall is increasing at all income and education levels. The incidence of type 2 diabetes mellitus is increasing in the United States. Among new cases of diabetes 81% are obese (BMI>30) and 49% have class II or III obesity (BMI>35). 4 Obesity related conditions such as stroke, heart disease, type 2 diabetes, and certain types of cancer (esophagus, breast -postmenopausal, endometrium, colon and rectum, kidney, pancreas, thyroid, and gallbladder) contribute to the estimated annual medical cost of treatment of obesity in the United States in 2008 of $147 billion. 3 5

Initial requirements for preoperative evaluation and management including:

Six consecutive months of participation in a medically supervised weight loss program within the setting of a pre-surgical multidisciplinary evaluation must be completed within one year before the prior approval request for the bariatric surgery. There is a demonstration of participant responsibility. 6 Patients must demonstrate motivation to comply with proposed post operative treatment, dietary modifications, and participation in long-term follow-up.

Documentation of nutritional assessment and counseling at each visit with at least one visit with a registered dietitian or nutritionist. Dietary history, eating disorder, pre-surgical caloric reduction, dietary behavior modification, and lifelong need for dietary changes must be completed. An opinion for candidacy for the proposed procedure must be offered. 

Psychosocial-behavioral evaluation must be completed within 12 months of prior approval request by a licensed psychologist, psychiatrist, clinical social worker, and/or advanced practice nurse in collaboration with co-signing psychiatrist. This evaluation must include:

  • mental health history, diagnoses, and current treatments/status

  • eating behaviors

  • substance abuse  evaluation

  • stress management

  • cognitive abilities

  • social functioning including support system

  • self esteem and personality factors

  • readiness to change and adhere to lifestyle modifications

  • opinion must be offered regarding the patient’s candidacy for the proposed procedure

  • commitment not to become pregnant before surgery and within 18 months following surgery

Comprehensive medical history and physical examination within 6 months of prior approval request that documents:

  • Previous attempts to lose weight with results over the past 2 years

  • Elaboration of comorbidities and interventions

  • The medical record must clearly indicate that any comorbidity is not a contraindication for the proposed surgery. 

  • Education regarding risks and benefits of bariatric surgery and procedural options. When there is an obvious disconnect in the communication process between the practitioner and patient due to the patient’s lack of proficiency in the English language, an interpreter is required.

  • Optimization of glycemic control.

  • Treatment of dyslipidemia.

  • Discontinuing estrogen therapy, if applicable.

  • Cardiology consultation and beta-adrenergic blockade, if indicated.

  • Preoperative weight loss should be considered in patients whom reduction of liver volume is expected to improve the technical aspects of surgery.

  • Chest radiograph – anterior posterior and lateral.

  • Pulmonary evaluation, including arterial blood gas measurement and polysomnography, if indicated.

  • Smoking cessation; addiction to alcohol and drugs must be addressed.

  • Diagnostic evaluation for deep venous thrombosis and vena cava filter, if indicated.

  • Abdominal ultrasonography and viral hepatitis screen.

  • Institution of CPAP or BiPAP as indicated for obstructive sleep apnea (OSA), obesity-hypoventilation syndrome (OHS), or Pickwickian syndrome. 7

  • Respiratory problems

    • OSA of at least moderate severity documented by sleep study

    • OHS documented by sleep study

    • Pickwickian syndrome (combination of OSA and OHS) documented by sleep study

    • Respiratory insufficiency, such as hypercapnia as evidenced by pCO2 greater than 50 mm Hg by arterial blood gas

    • hypoxemia at rest as evidenced by pO2 less than or equal to 55 mmHg on room air by arterial blood gas

    • FEV1/FVC less than 65%

    • DLCO less than 60% of predicted normal

Revisions/repeat bariatric surgery

  1. Revisions are necessary when there is documentation of a failure or secondary to a surgical complication including but not limited to one of the following: fistula formation, obstruction, stricture, esophagitis unresponsive to nonsurgical treatment, disruption/leakage due to failure of a suture or staple line, band herniation, hemorrhage, hematoma formation, excessive bilious vomiting, stomal dilatation documented by endoscopy, or weight loss of 20% or more below the ideal body weight.
  2. Revision surgery for replacement of an adjustable gastric band will be deemed necessary due to complications such as slippage or port leakage not remediable with band manipulation or adjustments.
  3. Revision bariatric surgery is warranted with gastric pouch dilatation, dilatation of the gastrojejunal stoma, or dilatation of gastrojejunostomy anastomosis documented by upper gastrointestinal (UGI) series or esophagogastroduodenoscopy (EGD) producing a weight gain of 20% or more above the stable nadir with the following documentation:
    • Original surgery successfully induced weight loss prior to the pouch dilatation as documented by submission of BMI prior to surgery,  BMI at lowest stable nadir, and most recent BMI

    • Pouch dilatation is due to a technical failure or vomiting and not due to stretching from overeating

    • The patient has been compliant with the prescribed nutrition and exercise program per surgeon’s statement and as evidenced by submission of post operative follow-up records

  4. Repeat procedures for revision or conversion to another surgical procedure is considered medically necessary when there is documentation of inadequate weight loss unrelated to a prior surgical complication when all of the following applies:

    • patient continues to meet the initial requirements

    • at least 2 years have lapsed since the original bariatric surgery with weight loss that is less than 50% of the pre-operative excess body weight  and weight remains at least 30% over ideal body weight – referencing standard tables for adult weight and height by the National Heart, Lung, and Blood Institute 9 or for adolescents by age and sex through growth charts for stature and weight percentiles, BMI index percentiles, and data tables of weight at the Centers For Disease Control and Prevention 10

    • the patient has been compliant with the prescribed nutrition and exercise program per surgeon’s statement and as evidenced by submission of post operative follow-up records
