Question:
CS Site Specific Factor--Breast: If the tumor is described as being a 1 cm poorly differentiated pleomorphic lobular carcinoma with scattered LCIS in breast tissue, for SSF6, do we use the breast tumor or all of the breast tissue removed when coding SSF6?
Discussion:
Answer:
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Site Specific Factor 6 in the breast scheme describes the relationship of invasive and in situ tumor in the tumor size coded. Code SSF6 for the same tumor used to code tumor size.
For this example, code SSF6 for the 1 cm tumor. In this case, the entire tumor is reported as invasive; use code 000 [Entire tumor reported as invasive].
