Reportability/Behavior--Skin: Is an "atypical fibroxanthoma (superficial malignant fibrous histiocytoma)" with an ICDO-3 histology code of 8830 considered reportable with a behavior code of 3 or is it nonreportable with a behavior code of 1?
Yes, "atypical fibroxanthoma (superficial malignant fibrous histiocytoma)" is reportable. The information in parentheses provides more detail and confirms a reportable malignancy.
Behavior/Date of Diagnosis--Lung: If the term "Pancoast tumor, NOS" is considered malignant by definition, should the date of diagnosis be coded to the date of the clinical diagnosis when the clinical diagnosis is made prior to the histologic confirmation of the malignancy?
Yes, Pancoast tumor is by definition malignant. It is defined as a lung cancer in the uppermost segment of the lung that directly invades into the brachial plexus (nerve bundles) of the neck, causing pain. If a Pancoast tumor was identified on imaging prior to the biopsy, the date of diagnosis should be linked to the Pancoast tumor report.
MP/H Rules/Multiple primaries--Breast: Is the diagnosis of Paget disease two years after a diagnosis of infiltrating duct carcinoma of the same breast a new primary? See discussion.
A patient was diagnosed and treated in 2010 for infiltrating duct carcinoma of the left breast. There was no mention of Paget disease. Then in 2012, the same patient was diagnosed with Paget disease of the nipple of the left breast. Rule M9 seems to apply; so this is the same primary, correct? And the information about the Paget disease is simply never captured, correct?
Yes, Rule M9 makes this a single primary. You could revise the original histology code to 8541/3 on the assumption that Paget was present at the original diagnosis, but not yet identified.
Surgery of Primary Site--Melanoma: If the surgical margins are greater than 1 cm for length and width but less than 1 cm for depth, do we code surgery in the 30-33 range?
Yes, assign a surgery code from the 30-33 range when any margin is less than 1 cm. Since tumor thickness is an important prognostic factor for cutaneous melanoma, the deep margin is of particular importance.
Surgery of Primary Site/Immunotherapy--Bladder: Is administration of BCG coded as both surgery and immunotherapy?
Yes, code as both surgery and immunotherapy. The CoC included immunotherapy/BCG under surgery and also under immunotherapy by request of the clinical advisor for bladder, reflecting the mixed-modality nature of the treatments. [Answer from CoC I & R]
Surgery of Primary Site--Colon: In the absence of detailed operative or pathology report descriptions of the specific segment(s) of the colon removed, should a hemicolectomy be coded if stated by the surgeon to be such?
Yes, code hemicolectomy as stated by the surgeon when there is no conflicting or additional information avaliable.
