CPT® Code 43847

Gastric restrictive procedure, with gastric bypass for morbid obesity; with small intestine reconstruction to limit absorption

The CPT® Code 43847 refers to a gastric restrictive procedure that includes gastric bypass specifically designed for the treatment of morbid obesity. This procedure is characterized by the combination of gastric restriction and the bypass of a significant portion of the small intestine, which is intended to promote fat malabsorption. The surgical approach typically involves making an upper abdominal midline incision to gain access to the stomach. During the operation, the liver is retracted to expose the upper part of the stomach, allowing the surgeon to identify critical anatomical landmarks such as the gastroesophageal junction. The procedure entails creating a small gastric pouch and performing a Roux-en-Y gastroenterostomy, which is a technique that connects the newly formed pouch to the small intestine. The unique aspect of this procedure is the reconstruction of the small intestine to limit nutrient absorption, which is achieved by creating a Roux limb that exceeds 150 cm in length. This surgical intervention is aimed at significantly reducing the volume of food intake and altering the digestive process to assist patients in achieving substantial weight loss and improving obesity-related health conditions.
