Date of Diagnosis--Colon: If a patient has a positive Cologuard test, is the date of diagnosis the date of the cologuard test or the date of the biopsy?
Date of Diagnosis--Brain and CNS: How is the Date of Diagnosis coded when an MRI clinically diagnoses a borderline brain tumor on 4/4/2020, but the subsequent biopsy pathologically diagnoses a malignant brain tumor on 5/20/2020? See Discussion.
CS Site Specific Factor--Prostate: Can autopsy results also be used when coding SSF3, pathologic extension, given that the instructions only address the use of prostatectomy findings when coding this field?
CS Site Specific Factor--Breast: What estrogen receptor/progesterone receptor (ER/PR) values should be coded in a case with two separate tumors (1 ductal, 1 lobular) diagnosed simultaneously in the same breast (single primary) with differing ER/PR values for each tumor? One is ER/PR positive; the other is ER/PR negative.
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?
