20091008 | Surgery of Primary Site--Breast: How is this field coded when a mastectomy and a sentinel lymph node excision, that yields only one lymph node, are performed? See Discussion. | Is there a minimum number of lymph nodes that must be removed in order to code a modified radical mastectomy? | Assign code 41 [Total (simple) mastectomy...] for a simple mastectomy with removal of one or more sentinel lymph nodes. As long as the nodes removed are designated sentinel, use code 41 for a simple mastectomy. | 2009 |
|
20091098 | MP/H Rules/Histology: How is histology coded for a partial vulvectomy showing "vulvar intraepithelial neoplasia III, basaloid type"? See Discussion. | Is this VIN III (8077/2) or basaloid squamous cell carcinoma (8083 and change the behavior code from 3 to 2)? It seems that H4 and H6 both lead to 8083. | For cases diagnosed 2007 or later, assign 8077/2 [Squamous intraepithelial neoplasia, grade III] for VIN III diagnoses, regardless of the type. According to the WHO Classification of Tumours (page 319), "VIN is predominately of the warty or basaloid types...." Use the multiple tumors module to determine the histology code for VIN. Rule H21 applies. |

20140015 | Primary site--Heme & Lymphoid Neoplasms: Is there an instruction missing under Rule PH22 of the 2014 Heme Manual that addresses when it might be appropriate to code primary site to C779 for a Stage II lymphoma? See discussion. | It appears there is no instruction under PH22 that covers Example 5 (The patient has a history of Stage II lymphoma, no other information is available). All the bulleted instructions are for organ and lymph node combination involvement. Was the 2010 Heme Rule PH31 (Code the primary site to lymph nodes, NOS (C779) when lymph node(s) are involved but no primary site/particular lymph node region is identified) supposed to be listed under PH22? There does appear to be an empty bullet on the current web version. | The 5th bullet under Rule PH 22 was inadvertently omitted. A corrected version of the Heme manual will be posted soon. Thank you for identifying this omission. In the meantime, please add the following to PH22: Code the primary site to lymph nodes, NOS (C779) when lymph node(s) are involved but no primary site/particular lymph node region is identified. |

20021122 | Histology (Pre-2007)--Breast: For a path diagnosis of ductal carcinoma in situ, cribriform type with apocrine features, does the term "apocrine" modify the term cribriform or does it represent another type of ductal carcinoma in situ? See discussion. | It can be difficult to determine if two terms mentioned in a pathology report are describing different aspects of the same morphology or if the two terms are describing two different morphologies. | For tumors diagnosed prior to 2007:
Code the Histology field to 8401/2 [Apocrine carcinoma in situ]. According to our pathologist consultant "Because apocrine is the more unusual tumor, and pulling it out of the cribriform category keeps the latter a little cleaner (because most cribriform ductal carcinoma in situ is not particularly apocrine), I am inclined to code to the histology to apocrine ductal carcinoma in situ."
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. |

20140005 | Primary site--Testis: In the absence of a specific statement that the patient's testicle(s) are descended, should the primary site for a testicular tumor be coded as C621 (Descended Testis) when the mass is palpable on physical exam or demonstrated on scrotal ultrasound? See discussion. | It seems the non-specific Testis, NOS (C629) code is being over used. Many testis cases have no documentation of the patient's testicular descention. However, testicular tumors in adults are frequently detected by palpation or scrotal ultrasound. An undescended testis (a testis absent from the normal scrotal position) would be non-palpable or not amenable to imaging via a scrotal ultrasound. | Unless the testicle is stated to be undescended, it is reasonable to code C621 for primary site. Reserve C629 for cases with minimal or conflicting information. | 2014 |
|
20051129 | Reportability/Behavior--Thyroid: Does the term "invasion" indicate the presence of a malignant tumor? See Discussion. | Left thyroid lobectomy showed microfollicular neoplasm with evidence of minimal invasion. Micro portion of path report stated, "The capsular contour is focally distorted by a finger of the microfollicular nodule which appears to penetrate into the adjacent capsular and thyroid tissue." | We recommend that you contact the pathologist for further information. If no further information is available, do not accession this case based on the information provided. There is no definitive statement of malignancy. If the case was sent to a consultant, there may be another opinion available. If there is information in the record, or the treating physician can be contacted, find out whether the tumor was benign or malignant and whether there was any further treatment. According to our pathologist consultant, based only on the information above and nothing else, do not report since there is no diagnosis of malignancy. |

20061024 | Histology (Pre-2007)--Kidney: How is a "mucinous tubular and spindle cell carcinoma" coded? See Discussion. | Literature search results: "The new WHO-classification of renal tumors includes new subtypes, one of which is the mucinous, tubular, and spindle cell carcinoma. Many of these tumors had been previously diagnosed as sarcomatoid carcinoma. There are areas of cord-like growth and spindle cell configuration, sometimes with a clear cell appearance." | For tumors diagnosed prior to 2007:
Code histology to 8255 [Adenocarcinoma with mixed subtypes]. ICD-O-3 does not have a code specific to this combination histology. 8255 is the best code available.
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. |

20091087 | Reportability--Appendix: Is a metastatic low-grade appendiceal mucinous neoplasm reportable if the pathologist states that it is a borderline tumor of the appendix? See Discussion. | Low-grade appendiceal mucinous neoplasm; Lt ovary, cul-de-sac, omentum, and small bowel: Metastatic low-grade appendiceal mucinous neoplasm. Per pathologist this is a borderline tumor of the appendix. | Borderline tumors (other than brain and CNS) are not reportable to SEER. In the case of borderline tumors, the term "metastatic" does not automatically make them reportable. When the "metastatic deposits" are also borderline, the case is not reportable. For this case in particular, the "metastases" are actually (benign) implants and not malignant or invasive mets. | 2009 |
|
20061139 | CS Lymph Nodes--Lung: Do modifying terms such as "borderline" affect whether lymph nodes are coded as involved when they are used in conjunction with the descriptors listed in Note 2 (i.e., mass, adenopathy or enlargement) for lung primaries? See Discussion. | Lung primary: CT states "borderline" enlarged hilar lymph nodes. Note 2 in the Lung schema under CS Lymph Nodes does not address qualifiers. | 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. Do not code the hilar lymph nodes as involved in this case. "Borderline" enlarged hilar lymph nodes do not meet the clinical criteria for enlargement. |

20091121 | MP/H Rules/Multiple primaries--Brain: Does a patient diagnosed with anaplastic astrocytoma of the left temporal lobe in 2000 followed by a diagnosis of oligoastrocytoma of the right frontal lobe in 2007 have a single primary per rule M7 or multiple primaries per rule M8? See Discussion. | MP/H rule M7 states that tumors with ICD-O-3 histologies on the same branch in chart 1 are a single primary. Chart 1 shows that both of the histologies for our sample case are located on the glial branch. However, the glial tumor branch has three secondary branches. Does rule M7 apply to secondary branches? Anaplastic astrocytoma [9402] is classified under the secondary branch for astrocytic tumors. Oligoastrocytoma [9382] is classified under the secondary branch for mixed glioma. Does rule M7 or does rule M8 apply for this case? Does this case represent one or two primaries? | For cases diagnosed 2007 or later, Rule M8 applies. There are two primaries.
Anaplastic astrocytoma and oligoastrocytoma (mixed glioma) are on separate branches in Chart 1. They are both gliomas, but one is a mixed glioma and the other is an astrocytic tumor. |
