pathology came back with Adenomatous polyps of distal sigmoid colon with Moderate surface dysplasia would you use D12.5 or D37.4 my understanding if the pathology came back with indications of atypia or dysplasia, the neoplasm is in transition from benign to malignant ( precancerous) . This is a neoplasm of uncertain behavior . It is not benign because benign has no precancerous cells, and it not malignant because it has not become cancer yet.
