CPT® Code 43842

The CPT® Code 43842 refers to a gastric restrictive procedure specifically designed for individuals suffering from morbid obesity, known as vertical-banded gastroplasty. This surgical intervention involves making a midline abdominal incision to gain access to the stomach. During the procedure, a small window is created in both the anterior and posterior walls of the stomach at its upper section. A line of staples is then applied from this window to the esophagus, effectively forming a small pouch at the upper part of the stomach along the lesser curvature. To further facilitate the restriction of food passage, the edges of the windows in the anterior and posterior walls are sutured together, creating a through-and-through hole. A plastic band is subsequently inserted through this hole and wrapped around the lesser curvature, positioned just below the newly formed gastric pouch. This band serves to prolong the retention of food within the pouch, thereby enhancing the sensation of fullness for the patient. It is important to note that vertical-banded gastroplasty is not commonly utilized in contemporary practice, with alternative techniques being preferred for creating a gastric pouch and restricting food passage without bypassing the stomach, as indicated by CPT® Code 43843.
