Marital Status: Is marital status coded to 2 [married] if the patient is legally married to a same-sex spouse (e.g., patient has a Canadian spouse and in Canada, same-sex marriages are legal)?
Code marital status for same-sex persons based on the legal status. For the case example above, assign code 2 [married].
Multiple Primaries (Pre-2007): How many primaries? See Discussion.
5/05 perianal skin bx, 6/05 mapping bx perianal skin, 9/05 punch bx perianal skin: all positive for extramammary Paget Disease. 9/05 Perianal Excision of Paget w/V-Y flap repair. Path: Perianal and anal skin: Extramammary Paget disease associated with: Invasive adenoca of anal canal. Anal margins positive for invasive adenoca. Comment: invasive adenoca with local mucinous features involving the anal margin/end of specimen. This adenoca is in continuity with (associated with) extensively diffuse extramammary Paget disease. Unclear whether the adenoca represents a rectal primary with spread to perianal area, anal gland adenoca or mets. 12/05 AP resection-no residual Paget or invasive neoplasm.
For tumors diagnosed prior to 2007:
There is one primary.
Code the histology to 8542 [Paget disease, extramammary]. Code the primary site C210 [anus]. Histology rule 7 on page 87 of the 2004 SPCM applies in this case.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Multiple Primaries/Histology--Lymphoma: If an oral mucosa, right hard palate biopsy contains a composite lymphoma [low-grade follicular + chronic lymphocytic leukemia], how many tumors should be abstracted and how should the histology field(s) be coded?
For cases diagnosed prior to 1/1/2010:This is one primary. Assign code 9590 [Malignant lymphoma, NOS]. This is a composite lymphoma. Code to lymphoma when there is any solid tumor (in lymph nodes, tissue, etc.) Code to lymphoma, NOS since this is not purely follicular and there is no code for composite lymphoma.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Reportability/Behavior--Skin: Is an "atypical fibroxanthoma (superficial malignant fibrous histiocytoma)" with an ICDO-3 histology code of 8830 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.
Histology (Pre-2007): Is an intra-abdominal mass with the histology of "squamous cell carcinoma arising in a dermoid cyst" coded to 8070/3 [Squamous cell carcinoma] or 9084/3 [Dermoid cyst with malignant transformation]?
For tumors diagnosed prior to 2007:
Code histology to 9084/3 [Dermoid cyst with malignant transformation] per the ICD-O-3. Dermoid cysts may contain a malignant component of a type typically encountered in other organs and tissues.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Multiple Primaries/Histology--Lymphoma: If a gastric biopsy demonstrates large B cell lymphoma arising in a low grade MALT lymphoma, how many tumors should be abstracted and how should the histology field(s) be coded? See Discussion.
Final path for gastric biopsy on 12/2005 is "consistent with malignant lymphoma" and Micro says "morphologic findings consistent with MALT lymphoma and an increased proportion of large atypical cells is concerning for large cell transformation. However, since the large cells are present only focally, a definitive diagnosis of large cell lymphoma cannot be rendered"
A second gastric biopsy a week later said: Final Path: Diffuse large B cell lymphoma arising in low grade MALT lymphoma. Micro says: "Compared to patient's previous biopsy...the current specimen contains a higher percentage of large atypical cells which stain positively for CD79a, a B cell marker. The morphologic and immunohistochemical findings are consistent with a large B cell lymphoma arising in a low grade MALT lymphoma."
These are different primaries according to the table of single versus subsequent primaries of lymphatic and hematopoietic diseases.
For cases diagnosed prior to 1/1/2010:
This is one primary. Code as 9699 [Marginal zone B-cell lymphoma, NOS].
The first biopsy was not conclusive. The biopsy one week later was more definitive. The reports are describing a difference between specimens, not a difference in disease.
According to the WHO classification, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is an extranodal lymphoma with B-cells, cells resembling monocytoid cells, small lymphocytes and scattered immunoblast and centroblast-like cells.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
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.
SINQ 20031152 states that histology for this type of case is to be coded per the clinical diagnosis of "carcinoma." Does it follow then that Diagnostic Confirmation is to be coded 8 (clinical diagnosis only)? Would we code Diagnostic Confirmation differently if the clinician stated that the diagnosis of malignancy was confirmed by the suspicious cytology?
Code diagnostic confirmation as 8 [clincial diagnosis] when there is a suspicious cytology and a physician's clinical diagnosis. Do not accession cases with only suspicious cytology.
Code diagnostic confirmation as 8 when the clinician's diagnosis of malignancy is confirmed by the suspicious cytology. It is still a clinical diagnosis made by the physician using the information available for the case.
Reportability--Ovary: Is an "aggressive adult granulosa cell tumor with one of two lymph nodes positive for metastatic granulosa cell tumor" reportable?
Malignant granulosa cell tumor is reportable. The case described above is malignant as proven by metastasis to the lymph node.
