Question:
Multiplicity Counter--Ovary: Given the diffuse nature of ovarian cancer, should we count bilateral parenchymal involvment of ovaries as two tumors? See Discussion.
Discussion:
Are peritoneal implantsĀ mets and not countedĀ as separate tumors, even though they're not stated to be metastatic in the path report, and are not coded as distant mets?
Answer:
Code Multiplicity Counter to 02 [Two tumors present] for an epithelial ovarian primary involving both ovaries. Do not count the peritoneal implants; they are regional metastasis and not included in the multiplicity counter. An example like this will be added to the manual in the next revision.
