Question: What is gastric adenoma, and how should I code it? Answer: Gastric adenoma is a benign tumor of the glandular epithelial cells lining the stomach and can be a premalignant condition in the stomach. Most GIs recommend a complete surgical removal, either by an endoscopic approach or laparoscopic wedge resection.
