Question:

Type of Multiple Tumors--Colon: How is this field coded for a case in which the patient is found to have two in situ polyps and an adenocarcinoma arising in a polyp all in the same segment of the colon? See Discussion.

Discussion:

Code 30 would not count the fact that these are polyps. Code 31 states "AND a frank adenocarcinoma." What would be the correct code?

Answer:

Assign code 30 [In situ and invasive] in this case. Code 31 does not apply here because frank adenocarcinoma is not present.
