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"?
Compound nevus with severe atypia is not reportable unless also stated to be malignant melanoma or melanoma in situ.
Grade, Differentiation--Lymphoma: What code is used to represent this field when the only grade/differentiation given is "low grade", "intermediate grade" or "high grade"?
Code the Grade, Differentiation field to 9 [cell type not determined, not stated or not applicable]. For lymphomas, do not code the descriptions "high grade," "low grade," and "intermediate grade" in the Grade, Differentiation field. These terms refer to categories in the Working Formulation and not to histologic grade for lymphoma histologies.
Generally, for histologies other than Non-Hodgkin lymphoma, the Grade, Differentiation field is coded to 2 [low grade], 3 [intermediate grade] and 4 [high grade] for most cancers.
CS Lymph Nodes--Breast: Must there be a statement of "moveable" present to code 25 in this field and if a lymph node is not stated to be "fixed" is it presumed to be moveable? Please provide an example in your answer of when to use code 25.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
The word "movable" does not have to be used to assign code 25. A "movable" lymph node is an involved lymph node not described as fixed or matted. The general rule is to code the lesser or lower category, which would be the case if neither movability nor fixation is mentioned. See page C-471 of the 2004 SEER Manual.
Code 25 Example: Involved lymph nodes per lymph node dissection. No mention of fixation or matting. Size of largest met within a lymph node is 4mm.
Code histology to 9732/3 [multiple myeloma]. The plasmablastic subtype/variant does have a prognostic indication, but the disease is still coded as multiple myeloma.

Histology (Pre-2007)/Diagnostic Confirmation: Which histology code is preferred if the CBD brushing is positive for malignant cells, cytologically most consistent with ductal adenocarcinoma [8500/3], and the common hepatic artery lymph node biopsy has metastatic adenocarcinoma, consistent with cholangiocarcinoma [8160/3]?
For tumors diagnosed prior to 2007:
Assign histology code 8160 [Cholangiocarcinoma]. Code from the pathology specimen when available. In this case, the only pathology is from the lymph node specimen.
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.
EOD-Extension--Small Intestine: How do we interpret a pathology description of "extending through serosa and forming masses in the periserosal tissue" for a jejunum primary?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 55 [Invasion of/through serosa and adjacent connective tissue]. The description states the tumor extended through the serosa into periserosal tissue. The periserosal tissue in this case refers to adjacent connective tissue lying exterior to the intestinal wall and not the (sub)serosal tissue that lies exterior to the muscularis but inferior to the serosa. Analyze each case individually since pathologists are not consistent when using the above terminology.
Reportability/Histology--Liver: Are primary hepatic neuroendocrine neoplasm and primary hepatic neuroendocrine tumor (PHNET) reportable? What are the specific histology codes?
Primary hepatic neuroendocrine tumor (PHNET) is reportable as are other digestive system NETs. There is no specific histology code for PHNET. We suggest you assign 8240/3. Use text fields to document the details.
Unless you can obtain clarification, do not report primary hepatic neuroendocrine neoplasm with no further information. If this term is being used as a synonym for PHNET, document this in the registry's policies and procedures, and report these cases.
Grade--Heme & Lymphoid Neoplasms: Why isn't "T-cell granular lymphocytic leukemia" (9831/3) coded as "5 T-cell" instead of "9" as specified in the Heme database? My path department did not specify any type of grade, but since "T-cell" is part of the name, wouldn't you code it to "5"?
Assign code 5 when the diagnosis on the pathology report specifies "T-cell granular lymphocytic leukemia." The Heme DB grade instruction states "Code grade specified by pathologist. If no grade specified, code 9." In this case, T-cell was specified - code it. The code for T-cell (5) was not automatically assigned in the Heme DB because of the alternate names for this neoplasm. Some of these include NK-cell. Assign code 8 for alternate names with NK.
The alternate names are: Chronic lymphoproliferative disorder of NK cells, Chronic NK-cell lymphocytosis, Chronic NK-large granular lymphocyte (LGL) lymphoproliferative disorder, CLPD-NK, Indolent large granular NK-cell lymphoproliferative disorder, NK-cell lineage granular lymphocyte proliferative disorder, NK-cell LGL lymphocytosis
Reporting Source: Is an ER patient who is diagnosed on peripheral smear with an acute leukemia coded as an outpatient if the patient died while in the process of being admitted for treatment or is the patient coded as a death certificate case?
Code reporting source as 1 [Hospital Inpatient/Outpatient or Clinic] for the case above. This case will be abstracted using information from the outpatient/ER record (and the death certificate).
