If partial gastrectomy was performed, was it distal or proximal?
Coding partial gastrectomy can be more complicated, as it can be either distal or proximal. CPT’s distal partial gastrectomy series is broken down in roughly the same manner as the total gastrectomy series: 43631 (Gastrectomy, partial, distal; with gastroduodenostomy), 43632 ( with gastrojejunostomy), 43633 ( with Roux-en-Y reconstruction) and 43634 ( with formation of intestinal pouch). Two other codes cover proximal partial gastrectomy: 43638 (Gastrectomy, partial, proximal, thoracic or abdominal approach including esophagogastrostomy, with vagotomy) and 43639 ( with pyloroplasty or pyloromyotomy). Note: When pyloromyotomy (43520) is performed with a proximal partial gastrectomy, bill for the latter only (43639). Do not code 43520 separately, as it is included in 43639. 5. Was a vagotomy performed? Vagotomy can prevent the stomach from producing acid that can lead to ulcer disease. You should not bill it separately when it is performed during partial proximal gastrectomy, as vagotomy
