Question:
Multiplicity Counter: Should this field be coded to 99 for cases of familial adenomatous polyposis (FAP)? See Discussion.
Discussion:
The MP/H rules state to abstract these cases as a single primary. The Type of Multiple Tumors Reported as One Primary field is coded as a single primary with a value of 32 (FAP with carcinoma), but the Multiplicity Counter seems to be unknown.
Answer:
Assign code 99 [Multiple tumors present, unknown how many] for cases of FAP when the number of tumors is not stated.
