CS Extension--Lung: If only a "single" cytology is performed on pericardial fluid and it is negative, can Note 6 B, which states that pleural effusion [code 72] is coded as malignant unless there are "multiple" negative cytologies, be used to infer that the pericardial fluid should also be coded as involvement?
CS Extension/CS Mets: For primary sites within the peritoneum (abdominalpelvic walls) such as stomach, colon, does the presence of malignant ascites affect the coding of CS Extension or CS Mets?
Reportability--Lymphoma: Is a lymphoma diagnosed on a bone marrow biopsy reportable if the cytogenetics evaluation performed does not confirm the malignancy? See Discussion.
Ambiguous Terminology--Breast: Is a stereotactic biopsy that is "focally suspicious for DCIS" reportable if it is followed by a negative excisional biopsy? See Discussion.
CS Tumor Size--Breast: Should this field be coded to 999 [Unknown] or 008 [0.8 cm tumor] when the tumor size is not provided on a stereomammotomy biopsy for an in situ malignancy and a subsequent excision demonstrates 0.8 cm tumor of residual in situ disease?
Reportability--Ovary: Is an "aggressive adult granulosa cell tumor with one of two lymph nodes positive for metastatic granulosa cell tumor" reportable?
CS Extension--Prostate: Does the term "activity" in a Prostascint report indicate a clinically apparent tumor, tumor extension or tumor involvement for this primary site? (http://www.rtrurology.com/prostascint.htm)
