20091011 | MP/H Rules/Histology--Breast: What histology is coded for a tumor diagnosed as "intraductal papillary carcinoma (neuroendocrine differentiation)"? See Discussion. | Final diagnosis states: Right breast, excisional bx with findings most consistent with intraductal papillary carcinoma (neuroendocrine DCIS). The path micro states: the morphologic features are those of a neuroendrocrine-type tumor & IHC stains confirm neuroendocrine differentiation. | For cases diagnosed 2007 or later, assign code 8503/2 [Intraductal papillary carcinoma] using Breast rule H2. Code the histology from the final diagnosis. There is no code for neuroendocrine DCIS in ICD-O-3. |

20031029 | Histology (Pre-2007)/Grading--Head & Neck: Can terms that commonly modify histologic types or grades be used if they are only expressed in the microscopic portion of the pathology report? See Description. | Final path diagnosis on a biopsy of the base of tongue is squamous carcinoma. The micro portion of the path report states the following: Multiple fragments of abnormal epithelium with a complex growth pattern. Many of the cells are small and poorly differentiated, interspersed with areas of well-differentiated keratinized epithelium. This is consistent with squamous cell carcinoma in situ with areas of invasive carcinoma. Do we code histology to 8070/3 or 8071/3? | For tumors diagnosed prior to 2007:
Yes, code using terms from the microscopic description if there is a definitive statement of a more specific histologic type. Code the case example as 8070/33 [Squamous cell carcinoma, NOS, poorly differentiated]. The microscopic description adds grade information, but does not make a definitive statement of a more specific histologic type. "Keratinized epithelium" is not the same as keratinizing squamous cell carcinoma (8071/3). The mention of "areas of well-differentiated keratinized epithelium" refers to "normal" tissue within the specimen, in contrast to a type of neoplastic tissue.
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. |

20021153 | Grade, Differentiation--Breast: Is "histological grade" another way of saying "tubule formation" which would result in the following case having a Bloom-Richardson (BR) score of 7 which would be coded to grade 2? See discussion. | Final path diagnosis stated: Invasive ductal ca, histological grade 3/3, nuclear grade 2/3, mitotic index-moderate. | Yes. Code the Grade, Differentiation field to 2 [Grade 2] for this case. This case has a BR score of 7 which converts to a grade of 2. This pathologist seems to be describing the three parts of the BR system: tubule formation, mitotic activity and nuclear grade. | 2002 |
|
20081086 | Reportability: Is a case reportable if a benign diagnosis is obtained on a resection that follows a positive needle aspiration? See Discussion. | Fine needle aspiration of the thyroid diagnosis was "positive for malignant cells, favor medullary carcinoma." Subsequent thyroidectomy was reported as benign. | This case is reportable. The cytology is positive. Report as medulary carcinoma of the thyroid. | 2008 |
|
20081065 | Surgery of Primary Site--Melanoma: Which surgery codes should be used for cases that have a 1 cm margin? See Discussion. | For a melanoma case the surgery codes in the 30's are to be used when margins are stated to be less than 1 cm. The codes in the 40's are to be used for cases where the margins are greater than 1 cm. | If the margin is exactly 1 cm, assign a surgery code from the 20-36 range. Use a code in the 40's only when the margin is greater than 1 cm. | 2008 |
|
20031078 | EOD-Lymph Nodes--Colon: Are "multiple submucosal lymphoid collections infiltrated with tumor" or "lymphoid areas" coded as lymph node involvement, similar to the way nodules in the pericolic fat are coded? See Description. | For an adenocarcinoma in the colon, under the "lymph node" section of the final path diagnosis it states "multiple submucosal lymphoid collections infiltrated with tumor" in addition to "one of two involved lymph nodes." The micro description states "There are multiple small lymphoid areas with tumor. A definite node excised from the mesentery shows...replacement of stroma and an additional very small node shows no tumor." | For cases diagnosed 1998-2003: No, do not code tumor infiltration of lymphoid collections or lymphoid areas as lymph node involvement. However, code lymph node involvement for this case as 3 [mesenteric, NOS] because a mesenteric node is involved. Regarding tumor infiltration of lymphoid collections or lymphoid areas from our pathologist consultant: Unless the anatomy of lymph node is evident (sinuses, trabeculae, primary and secondary follicles) these aren't lymph nodes and should not be coded as such. Unless there is evidence to the contrary in the path report, I would suggest that this be considered intramural spread, not lymph node spread. |

20020049 | EOD-Extension--Breast: Should clinically mentioned "thickening" of the breast be ignored if the pathology report does not mention thickening or skin involvement? See discussion. | For cases diagnosed 1998-2003: Can clinical "thickening" of the breast be coded to 20-28 extension code when there is no mention of the thickening or skin involvement in the pathology report? How do we code cases when pathology reports don't support the clinical finding of skin involvement. | For cases diagnosed 1998-2003: Do not use code 20-28 when there is no preoperative treatment and the pathology report does not confirm skin invasion. The clinical diagnosis of skin involvement was not supported by the pathology report. | 2002 |
|
20130191 | Systemic/Surgery Sequence--Bladder: How is the systemic treatment/surgery sequence field coded for a 2013 case if the patient has a TURBT followed by multi-agent chemotherapy, and then a cystoprostatectomy followed by post-operative multi-agent chemotherapy? | For cases diagnosed in 2012 and later, code 7 (surgery both before and after systemic therapy) seems like the most appropriate answer. However, previous SINQ entries 20091055 and 20071102 have conflicting answers regarding surgery before and after systemic therapy. Do these SINQ entries apply to a 2013 diagnosis? Would the systemic treatment/surgery sequence be coded 7 because this patient had surgery then chemotherapy followed by more surgery? Should the post-operative systemic treatment be ignored in coding the sequence in this case? | Code the Systemic/Surgery Sequence to 7 [surgery both before and after systemic therapy] for this case.
The answers to SINQ 20091055 and 20071102 do not apply to a case diagnosed in 2013. These answers were posted prior to code 7 becoming effective in 2012. |

20021051 | EOD-Extension--Pancreas: Can you explain the difference between code 10 [confined to pancreas] and code 30 [Localized, NOS]. See discussion. | For example, a CT scan mentions no extension beyond the head, body or tail of the pancreas and there is no surgical resection. Should we code extension to 10 or 30? | For cases diagnosed 1998-2003:
Code the EOD-Extension field to 10 [confined to pancreas] because a scan supported the finding of no extension beyond the pancreas.
If the abstractor reviewing the medical record has scans, op reports, and/or pathology reports stating that the tumor is confined to the pancreas, code extension to 10 [confined to pancreas].
However, if the medical record only provides a patient history from a physician stating that the patient had localized pancreas, code extension to 30 [localized, NOS]. The NOS codes are used only when there is not enough information to code the specific codes (in this case, 10 or 20). |

20031141 | Priorities/EOD-Lymph Nodes--Breast: Which part of the pathology report takes precedence when there is a discrepancy between the final path diagnosis and the CAP summary? See Description. | For example, breast primary: Final path states "14/18 nodes (+) for tumor & separate matted aggregate of axillary nodes (+) for tumor. Subpectoral lymph node (+) for mets ca. Path Gross states "18 separate lymph nodes identified...many (+) for tumor grossly. Aggregate of matted lymph nodes within axillary tissue (+) for tumor. Multiple separate lymph nodes submitted." CAP Micro Summary lists "20/16 nodes examined/positive." What is correct number of nodes positive & nodes examined in this case? | For cases diagnosed 1998-2003: The final pathology diagnosis has highest priority. The CAP summary is second priority. However, you always use the best information available. If the final path diagnosis is vague or unclear, information from the CAP summary can be used. In the case example, the total lymph node count from the final path diagnosis is unclear and the CAP summary provides clarification. Code the number of lymph nodes positive as 16 and the number examined 20. Subpectoral lymph nodes are regional nodes for breast primaries. | 2003 |
