Obesity is the most frequent form of malnutrition in the developed world and it is increasing. Morbid obesity (i.e., obesity with secondary serious or debilitating progressive disease) is generally associated with a body mass index (BMI) of ≥40 kg/m² (i.e. weight/height squared). Morbid obesity has a significant impact on cardiac risk factors, incidence of diabetes, obstructive sleep apnea, debilitating arthritis of weight bearing joints, infertility, psychosocial and economic problems and various types of cancers, etc.
The first treatment of morbid obesity is dietary and lifestyle changes. When conservative treatment fails, a few patients may require a surgical approach. A 1991 National Institutes of Health (NIH) Consensus Conference defined surgical candidates as those who meet the following criteria:
- Patient has a BMI of 40 kg/m² or greater than 35kg/m² in conjunction with severe comorbidity such as cardiopulmonary complications or severe diabetes
- Super obesity described as BMI >50kg/m²
- Failure of sustained weight loss with supervised dietary and conservative treatment over the years
- Motivated individual with acceptable operative risk
Surgery for morbid obesity, also known as bariatric surgery is based on intestinal malabsorption and gastric reduction. Surgery is considered successful if weight loss is maintained at greater than or equal to 50% of excess body weight for more than 10 years.
Several different gastric reduction and intestinal malabsorption procedures are listed below:
Gastric reduction (gastric restrictive) procedures:
- Vertical-banded gastroplasty
- Adjustable gastric banding
- Gastric bypass (Roux-en-Y gastroenterostomy); this can be done by both open or laparoscopic approach
- Laparoscopic silicone gastric banding
- Mini-gastric bypass (laparoscopic)
Malabsorptive Procedures:
- Biliopancreatic bypass (Scopinaro Procedure)
- Biliopancreatic bypass with duodenal switch
The following surgical procedures for the treatment of morbid obesity may be considered medically necessary when the criteria listed below are met: These are the ones that they will consider with preauthorization
- Vertical-banded gastroplasty
- Gastric bypass (Roux-en-Y gastroenterostomy) with short Roux limb equal to or less than 150 cm; this can be done by both open or laparoscopic approach
- Adjustable gastric banding (Lap-Band® procedure)
Criteria for Coverage:
- Patient is at least 18 years old
And
- The patient must have a documented medical history of failure to sustain weight loss with medically supervised dietary and conservative treatment for at least three years including within two years preceding surgery. Medically supervised treatment consists of physician documentation of the assessment of the patient, what health interventions are prescribed and their on-going assessment of patient's progress toward a goal of weight loss or control of an obesity-related comorbidity.
And
- The patient must be a motivated individual with acceptable operative risk and must be evaluated by a licensed mental health provider to determine the patient's willingness to comply with pre and postoperative treatment plans, and a strategy to ensure cooperation with follow-up must be documented.
And, in addition to the general requirements above, the patient must also meet one of the following weight criteria:
- BMI of 40kg/m² for at least 3 years
Or
- BMI of greater than 35kg/m² in conjunction with at least one of the following:
- Hypertension requiring medication for at least one year
- Diabetes Mellitus type 2 requiring medication for at least one year
- Obstructive sleep apnea, confirmed by sleep study, which does not respond to conservative treatment
- Documented cardiovascular disease
- Pulmonary hypertension of obesity
The following surgical procedures for the treatment of morbid obesity are considered investigational:
- Mini-gastric bypass (laparoscopic)
- Biliopancreatic bypass with duodenal switch ( its in black and white)
- Laparoscopic silicone gastric banding
- Biliopancreatic bypass (Scopinaro Procedure)
- Long-limb ( > 150 cm) gastric bypass
Subsequent bariatric procedures, including revisions, in patients *****gain weight due to failure to comply with lifestyle or dietary modifications are considered not medically necessary.
