CPT® Code 43820

The procedure described by CPT® Code 43820 is known as gastrojejunostomy without vagotomy. This surgical intervention involves creating a connection between the stomach and the jejunum, which is part of the small intestine, without the need to remove any sections of the stomach, duodenum, or jejunum. The primary goal of this procedure is to facilitate the passage of food from the stomach into the jejunum, particularly in patients who may have conditions that obstruct normal gastric emptying or require bypassing certain areas of the gastrointestinal tract. Various surgical techniques can be employed during this procedure, including retrocolic and antecolic approaches, which refer to the positioning of the anastomosis relative to the colon. The operation typically begins with a midline incision in the abdomen to access the stomach and jejunum, followed by the mobilization of these organs and the careful dissection of any adhesions that may be present. The procedure is performed with precision to ensure that the connection between the stomach and jejunum is secure, allowing for effective digestion and nutrient absorption post-surgery. It is important to note that this specific code does not include vagotomy, which is a separate procedure that involves cutting the vagus nerve to reduce acid secretion in the stomach, often indicated for patients with peptic ulcer disease.
