Question
MP/H Rules/Primary site/Histology--Colon/Rectum: How are the primary site and histology to be coded for a diagnosis of familial polyposis with malignant tumors in the sigmoid and rectum? See Discussion.

Discussion
Preoperative diagnosis was familial polyposis with rectal and rectosigmoid cancer.

The pathology report from the colon resection showed:
  1. 5 mm tumor in the sigmoid. Histologic type: adenocarcinoma.
  2. 1.9 cm tumor in the distal rectum. Histologic type: adenocarcinoma with signet ring cell differentiation.
  3. 4 cm tumor in the proximal rectum. Histologic type: adenocarcinoma.
Gross description: The mucosa of the colon is tan pink with polyposis throughout; more than 1000 tan sessile polyps.

Should this be a single primary per MP/H Rule M3, histology coded to 8220/3 [familial polyposis] per MP/H Rule H17, and primary site coded to C199?

Answer
This case should be accessioned as a single primary. Code the primary site to the colon and rectum [C199] and the histology to adenocarcinoma in familial polyposis coli [8220/3] per MP/H Rule H17.

For cases of familial polyposis, when the rectosigmoid or rectum are involved, assign code C199 [colon and rectum]. When the rectosigmoid or rectum are not involved, assign code C189 [colon, NOS].
