Histology Coding Rules: Colon/Rectum

Multiple Tumors in Same Organ Reported as Single Primary

1. Code histology when multiple tumors have same histology

Example: Well differentiated adenocarcinoma of rectum; separate metastatic tumor island, adenocarcinoma, with irregular contours present in fat

Answer: 8140/31 Adenocarcinoma

The rules for multiple tumors in the same organ reported as a single primary follow.

Rule 1: Code the histology when multiple tumors have the same histology.

Example: There is a tumor in the rectum with adenocarcinoma as well as a separate metastatic tumor island in the fat with adenocarcinoma. Because the tumor island in the fat has irregular contours, it is considered a metastatic nodule and not lymph node metastasis. This is a single primary, and the histology is recorded as adenocarcinoma (8140/3).
