Hello,
You could use 43644 for gastric restrictive procedure with gastric bypass with the Gastroenterostomy tube included. Here's a description of the different types below with laparoscopic guidance and without.

Bariatric Surgery
Three new gastric restrictive surgery codes were added to reflect the rapidly expanding field of bariatric surgery. Codes 43644 and 43645 employ laparoscopic techniques to perform gastric restrictive procedures for morbid obesity, including Roux-en-Y gastric bypass and small bowel reconstruction to limit absorption. The Roux-en-Y gastric bypass procedure is the most frequently performed bariatric procedure in the United States.
43644 Laparoscopy, surgical, gastric restrictive procedure; with gastric bypass and Roux-en-Y gastroenterostomy (roux limb 150 cm or less)
43645 Laparoscopy, surgical, gastric restrictive procedure; with gastric bypass and small intestine reconstruction to limit absorption
Code 43845 was added to describe a biliopancreatic diversion with duodenal switch, a surgical treatment for morbid obesity that combines moderate gastric restriction with a mechanism that promotes fat malabsorption and includes duodenal division and pylorus preservation with two reconstructive anastomoses.
43845 Gastric restrictive procedure with partial gastrectomy, pylorus-preserving duodenoileostomy and ileoileostomy (50 to 100 cm common channel) to limit absorption (biliopancreatic diversion with duodenal switch)
For consistency, an editorial revision was made to the existing open Roux-en-Y code 43846 to designate short limb to be 150 cm as specified in the laparoscopic Roux-en-Y gastroenterostomy code 43644.
43846 Gastric restrictive procedure, with gastric bypass for morbid obesity; with short limb (150 cm or less) Roux-en-Y gastroenterostomy
In a gastric bypass for morbid obesity (code 43846), the stomach is partitioned with a staple line on the lesser curvature (no band, no gastric transection). A short limb of small bowel (less than 100 cm) is divided and anastomosed to the small upper stomach pouch.
The revision to code 43846 more accurately describes the location of the division of the section of small intestine and reflects the typical current practice for this procedure, which has become the standard of care to perform a longer Roux-en-Y gastroenterostomy (limbs up to 150 cm). This procedure has evolved in order to provide more effective treatment for patients with greater obesity (ie, 225% of ideal body weight or greater). In these patients, a 150 cm proximal Roux-en-Y procedure (long-limb gastric bypass) has been found to increase weight loss to two thirds of excess weight without causing an increase in nutritional complications.
