20061055 | 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. | Example 1: Descending colon excision: Metastatic adenocarcinoma in 8 of 9 lymph nodes.
Example 2: Hepatic flexure and en bloc resection of liver. Adenocarcinoma in 3 of 10 lymph nodes. |
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. Code positive nodes included with the resected specimen as regional lymph nodes, NOS when the location is not stated. See number 3.e under the general instructions for coding CS lymph nodes. Based only on the information provided, code CS lymph nodes 30 [Regional lymph nodes, NOS] for both examples. |

20061011 | CS Site Specific Factor/CS Lymph Nodes--Breast: If the ITCs are greater than 0.2 mm, how are these fields coded? | 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. Lymph nodes with metastases greater than 0.2 mm are counted as positive. Code in CS Lymph Nodes and CS Regional LN Positive. Do not code ITC's greater than 0.2 mm in CS Site Specific Factor 4. |

20061034 | Primary Site--Unknown & ill-defined site: Is the primary site code C809 [Unknown primary site] preferred over the use of a site code for an organ system (e.g., biliary tract, NOS) or a specific primary site (e.g., colon, NOS) when these are "favored" but other potential sites "cannot be excluded"? See Discussion. | Case 1 - CT: Mult pulm nodules, bilat pleural effusions; paraaortic, paracaval, celiac lymphadenopathy. Lytic lesions L4&L5. Bx L3: Met pd adenoca. Based on the histopathologic features and the results of the immunostains, cholangiocarcinoma is regarded as the most likely primary. However, other possible primaries include pancreas, stomach, and (remotely) lung. Should primary be coded as C26.9, digestive organ, NOS?
Case 2 - CT: Mult liver masses. Liver Bx: Mod diff adenoca. The most likely primary sites include cholangiocarcinoma, stomach and pancreas. FDx per attending: Met adenocarcinoma to the liver, probably biliary origin. What primary site code do we use?
Case 3 - Admitting Dx: Unknown primary with mets to lungs, liver and cerebellar area. Liver Bx: Met adenoca. The combination of morphological and immunohistochemical staining favor a colon primary. However other possibilities include cholangiocarcinoma and pancreatic ca. Should we code site as C18.9 or C26.9? |
Code the primary site according to the physician's opinion. An ill-defined site code or an NOS code for the organ system is preferred over C809 [Unknown primary site] whenever possible. Code C809 only when there is not enough information to use an ill-defined or NOS code. Case 1 and Case 2 - Assign code C249 [Biliary tract, NOS]. Based on the available information, the physicians believe these are most likely biliary primaries. Case 3 - Assign code C189 [Colon]. According to the available information, the physician believes this is most likely a colon primary. |

20061108 | Histology/Polyp--Colon: Which histology code is used when a colon biopsy states adenocarcinoma arising in a polyp, but the resection path states only adenocarcinoma, and does not mention arising in a polyp. See Discussion. | This scenario occurs frequently and our QC staff is divided on which code to use. 03-24-06 Rectal Polyp: Adenocarcinoma, moderately differentiated. 6-29-06 Rectum: Adenoca, MD, invades into the submucosa. No malignancy (0/15) LNs. |
Use the polyp information from the biopsy and code adenocarcinoma arising in a polyp (8210, 8261 or 8263 as appropriate). | 2006 |
|
20061053 | 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. |

20061010 | 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. |

20061057 | 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. | Example 1: Lung primary within the right lower lobe described clinically as greater than 3 cm on scan but was found to be 3 cm at autopsy. Example 2: CT scan February shows 2 cm mass in RUL. In both cases, the only tumor description was the size of tumor without any information regarding extension. |
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. Yes, assign code 10 [Tumor confined to one lung] for a mass in one lobe when none of the descriptions in codes 11 to 80 are documented. |

20061102 | Histology (Pre-2007)--Lung: How is a poorly differentiated non-small cell carcinoma with "squamoid differentiation" coded? | For tumors diagnosed prior to 2007:
Squamoid and squamous are synonymous. Squamoid is non-standard terminology. It means "squamous like" and is a synonym of squamous.
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. |

20061018 | Multiple Primaries (Pre-2007)--Brain and CNS: Is neurofibromatosis a separate and distinct primary in the presence of a longstanding glioma? Does the following show one or two primaries? See Discussion. | MRI of Brain: 1. Findings compatible with left optic nerve glioma. 2. Stable enhancing focus in left temporal white matter. Lack of interval change since Dec 2000 suggests a white matter finding typical of neurofibromatosis and makes more aggressive processes such as astrocytoma less likely. Small aneurysm can not be excluded. | For tumors diagnosed prior to 2007:
Neurofibromatosis and glioma would be separate brain/CNS primaries. However, there is only one primary in the case example above: Glioma, left opic nerve. "...suggests a white matter finding typical of neurofibromatosis" is not reportable. "Suggests" is not a reportable term. Therefore, in this example neurofibromatosis is not reportable unless there is a more definitive statement in the record.
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. |

20061131 | CS Lymph Node Examined--Lung: How is this field coded when a mediastinoscopy and lobectomy are performed and the pathology report indicates multiple lymph node fragments were removed as biopsy specimens and the lobectomy specimen revealed 3 interlobar lymph nodes? | 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. Code the CS Lymph Node Examined field to 98 [number unknown] because the biopsy information is not clear and as a result you do not know how many lymph nodes were examined. |
