CPT® Code 43631

A partial gastrectomy, specifically a distal gastrectomy, is a surgical procedure aimed at removing the lower portion of the stomach. This operation is typically indicated for various gastrointestinal conditions that necessitate the removal of part of the stomach to alleviate symptoms or treat underlying diseases. During the procedure, a surgical incision is made in the abdomen to access the stomach. The surgeon carefully divides the stomach at the pylorus, which is the opening from the stomach into the duodenum, allowing for the mobilization of the stomach to expose critical blood vessels, particularly the left gastric artery. This artery is essential for supplying blood to the stomach, and its careful management is crucial during the surgery to prevent excessive bleeding. The procedure involves evacuating the contents of the stomach and decompressing it to facilitate a clear surgical field. The surgeon identifies and ligates branches of the left gastric artery to ensure proper blood flow is maintained to the remaining stomach tissue. After confirming hemostasis, which is the cessation of bleeding, the surgeon marks the sites for resection. The stomach is then divided, and a staple line is applied to secure the remaining stomach tissue. This staple line is subsequently oversewn with sutures to enhance closure and prevent leakage. Finally, the remaining segment of the stomach is aligned with the intestine, and sutures are placed to create an anastomosis, which is the surgical connection between the stomach and the duodenum. It is important to report the appropriate CPT® code based on the specific anastomosis performed; code 43631 is used when the stomach is connected to the duodenum, while code 43632 is used if the connection is made to the jejunum. This procedure is significant in managing various gastric conditions and requires careful surgical technique to ensure patient safety and optimal outcomes.
