CS Site Specific Factor--Prostate: How are SSF 5 (Gleasons Primary and Secondary Pattern Value) and SSF 6 (Gleasons Score) coded when there is a higher Gleason's pattern in less than 5% of the tumor? 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 Extension--Lung: Can extension be coded to 10 (Tumor confined to one lung) when either an autopsy or a CT scan describes the tumor as a mass of a specified size located in one lobe of the lung without any description of extension and no available TNM provided? See Discussion.
CS Lymph Nodes--Colon: What criteria is used to distinguish between code 30 [Regional lymph nodes, NOS] and 80 [Lymph nodes, NOS] when positive lymph nodes are removed during a colon resection but the lymph node location is not stated? See Discussion.
Diagnostic Confirmation: How is this field coded for a case with a cytology that is suspicious for ductal carcinoma and the clinical diagnosis is carcinoma? See Discussion.
Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?
Reportability--Melanoma: Is the final diagnosis for an excisional skin biopsy of "compound nevus with severe cytoarchitectural atypia and regression" reportable if a re-excision may be clinically indicated because there is an "overlap of morphology between malignant melanoma and nevi with severe atypia, and there's evidence of regression"?
