Bariatric Surgery. Surgical procedures performed to treat co-morbid conditions associated with morbid obesity. Bariatric surgery is based on two principles: Divert food from the stomach to a lower part of the digestive tract where the normal mixing of digestive fluids and absorption of nutrients cannot occur (i.e., Malabsorptive surgical procedures); or (2) Restrict the size of the stomach and decrease intake (i.e., Restrictive surgical procedures).
32 CFR § 199.2
General. In an effort to be as specific as possible as to the word and intent of CHAMPUS, the following definitions have been developed. While many of the definitions are general and some assign meaning to relatively common terms within the health insurance environment, others are applicable only to CHAMPUS; however, they all appear in this part solely for the purpose of the Program. Except when otherwise specified, the definitions in this section apply generally throughout this part.
