Question:

Multiplicity Counter/Type of Multiple Tumors--Breast: How are these data items coded for a single breast primary composed of both in situ and invasive disease when measurements are provided for both the invasive and in insitu components? See Discussion.

Discussion:

Breast cancer, invasive duct carcinoma with DCIS, 1.3 cm, DCIS 3.7 cm. "The in situ carcinoma is very extensive in this lumpectomy. It is present contiguously from sides 1A through 1L sparing only the final 8 mm of medial margin. In situ and invasive carcinoma are prominently present along almost the entire superior margin." Is the mult counter 02 with Type of mult tumor 30, or one tumor?

Answer:

Because there are individual measurements for each of these tumors, code the multiplicity counter 02 [Two tumors present]. Code Type of Multiple Tumor as 30 [In situ and invasive].
