20120019 | Surgery of Primary Site/Scope Regional LN Surgery--Breast: How are these fields coded for breast cases diagnosed 2011 and later when the patient has a simple mastectomy with removal of seven sentinel lymph nodes? See Discussion. | Per SINQ 20091076, the correct codes would be 41 [simple mastectomy] and 2 [sentinel lymph node biopsy only] when the patient has any number of sentinel nodes removed, as long as they are designated as sentinel nodes. Under the mastectomy codes in the 2011 SEER Manual, Appendix C, Breast Surgery Codes, the SEER Note states that code 41 [simple mastectomy] includes the removal of one to three axillary lymph nodes. A simple mastectomy with four or more axillary lymph nodes is coded to 51. Does the lymph node count for code 51 include both sentinel and axillary lymph nodes? Or does code 51 refer to strictly the count of axillary lymph nodes, separate from the count of sentinel lymph node(s) biopsied? | First, make sure that the seven lymph nodes removed were actually designated to be sentinel nodes and not a combination of sentinel nodes and other regional nodes. Code sentinel nodes only when the nodes are stated to be sentinel nodes or when the surgical procedure includes the injection of dye to identify sentinel nodes. If all seven nodes removed are sentinel nodes, follow the instructions in SINQ 20091076 and assign codes 41 [simple mastectomy] and 2 [sentinel lymph node biopsy only]. The SEER Note does not pertain to nodes designated as sentinel nodes. |

20120027 | MP/H Rules/Histology--Colon: How is histology coded if a patient has two frank invasive adenocarcinomas in one segment of the colon and multiple tubular adenomas and hyperplastic polyps throughout the entire colon without a diagnosis of familial polyposis [FAP]? See Discussion. | Does Rule H19 apply which indicates the histology is coded to 8221 [adenocarcinoma in multiple adenomatous polyps] because there are multiple polyps (number not specified) throughout the colon? Does tumor have to arise in at least one of the adenomas in order to apply Rule H19? Or, does Rule H22 apply which indicates the histology is coded to 8140 [adenocarcinoma, NOS] because the adenocarcinomas are both frank invasive adenocarcinomas and not adenocarcinoma arising in an adenoma? |
Code the histology as adenocarcinoma, NOS [8140/3].
For cases diagnosed 2007 or later, the steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text) and go to the Colon Histology rules to determine the histology code for this case. The Module you use depends on the behavior and number of tumors identified in the primary site.
Start at the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY Module Rule H15. The rules are intended to be reviewed in consecutive order from Rule H15 to Rule H24. Stop at the first rule that applies to the case you are processing. Code the histology when only one histologic type is identified. In this case, the only histology present was adenocarcinoma, NOS [8140/3].
Rules H17 through H21 do not apply in this case because there is no malignancy arising in any of the adenomas or polyps scattered throughout the colon. |

20120075 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for chronic lymphocytic leukemia/small lymphocytic lymphoma when a lymph node biopsy was positive for CLL/SLL but no bone marrow biopsy was performed? See Discussion. | A right neck lymph node biopsy and flow cytometry proved CLL/SLL. The PET scan showed multiple involved lymph nodes in the right cervical, mediastinal and para-aortic areas. No bone marrow biopsy was done. Per the Hematopoietic DB, Module 3, the histology should be coded 9823/3 [CLL/SLL], but how is primary site coded? The manual states to code the primary site to the involved lymph node region when there is no bone marrow involvement, but it does not specifically address how to code the primary site when no bone marrow biopsy or peripheral blood smear was done. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to C77.8 [multiple lymph node regions, NOS].
Per Rule PH6, code the primary site to the involved lymph node region(s) when there is no bone marrow involvement or when it is unknown whether the bone marrow is involved. To determine the more specific lymph node subsite to code, use Rule PH21. It indicates one is to code the primary site to C778 [multiple lymph node regions, NOS] when multiple lymph node regions, as defined by the ICD-O-3 (see Table C1: Lymph Node/Lymph Node Chain Reference Table in Appendix C), are involved and it is not possible to identify the lymph node region where the lymphoma originated.

20120036 | Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C779 or C809 when a patient is diagnosed at another facility with mantle cell lymphoma and the staging bone marrow biopsy performed at this facility is negative? There is no available information concerning where the lymphoma originated. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per PH Rule22, code the primary site to C779 [lymph nodes, NOS].
Rule PH22 is a default rule for lymphomas that is used when there is no other information regarding the primary site and the Heme DB does not indicate a primary site under its Primary Site(s) section. Rule PH27, code the primary site to unknown [C809], does not apply. Only use C809 [unknown] as the primary site when there is no evidence of lymphoma in lymph nodes AND the physician documents that the lymphoma originates in an organ(s).

20120088 | MP/H Rules/Multiple primaries--Head & Neck: How many primaries are accessioned and what rule applies if a patient has an extensive tumor in the left ethmoid sinus and a separate tumor in the right maxillary sinus? See Discussion. |
MRI and CT Neck Impression: Extensive tumor mass which likely originated within the left ethmoid sinus and extends intracranially via the cribriform plate into the anterior cranial fossa. There is involvement of the left orbit and extension into the superior aspect of the left maxillary sinuses as well as the nose. Second enhancing lesion within the right maxillary sinus measures almost 2 cm. The second mass within the floor of the right maxillary sinus, with similar imaging characteristics, is consistent with malignant involvement. The patient has an extensive ethmoid sinus tumor, biopsy showed squamous cell carcinoma. The ethmoid sinus is not a paired organ. The patient also has a small maxillary tumor with no histologic confirmation, Hem/Oncology chart notes state the right maxillary sinus mass is carcinoma. The maxillary sinus is a paired organ. Per the AJCC Manual (AJCC Manual for Staging, 7th edition, page 70), both the ethmoid and maxillary sinuses are further identified by their laterality (left and right). Why aren't the ethmoid sinuses a paired organ for the MP/H Rules? What MP rule applies to this case? |
For cases diagnosed 2007 or later, accession a single primary. The steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Head and Neck MP rules after determining the histology of each tumor - (8070/3 [squamous cell carcinoma] and 8010/3 [carcinoma, NOS]) because site specific rules have been developed for this primary. Start at the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within a module. Abstract a single when one tumor is carcinoma, NOS [8010] and another tumor is a specific carcinoma, squamous cell carcinoma [8070] because the ethmoid sinus (site of origin) is not a paired site per the MP/H rules. We will review the list of paired organs for the next edition of the MP/H Rules. |

20120074 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a patient is diagnosed in 2004 with extranodal diffuse large B-cell lymphoma (DLBCL) of the stomach followed by a 2011 diagnosis of DLBCL involving abdominal lymph nodes? See Discussion. | In 2004 a patient's extranodal DLBCL was treated with a partial gastrectomy at another facility. A recurrence of DLBCL was diagnosed in 2011 by a fine needle aspiration of abdominal lymph nodes. The patient presented to this facility for chemotherapy. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case is accessioned as a single primary. Code the histology to 9680/3 [diffuse large B-cell lymphoma] and diagnosis date to 2004. Per Rule M2, abstract as a single primary when there is a single histology.

20120079 | Reportability: Is positive urine cytology (ex: malignant cells interpreted as carcinoma) by itself reportable? If so, is the case coded to bladder by default or is is coded to C689, urinary system, NOS? | Urine cytology positive for malignancy is reportable. Code the primary site to C689 in the absence of any other information.
However, if a subsequent biopsy of a urinary site is negative, do not report the case.
For 2013 diagnoses and forward, report these cases when they are encountered. Do not implement new/additional casefinding methods to capture these cases. As always, do not report cytology cases with ambiguous terminology. |

20120082 | MP/H Rules/Multiple primaries--Breast: How many primaries are accessioned if the patient has two tumors in the left breast, one that is ductal carcinoma with mucinous differentiation and the other is ductal carcinoma, NOS? See Discussion. |
The final diagnosis from the left mastectomy was multifocal invasive ductal carcinoma (mpT1cN0) with associated intermediate grade ductal carcinoma in situ located between the invasive foci. Larger 2:00 focus: moderately differentiated ductal carcinoma with mucinous differentiation (1.4 cm). Smaller 3:00 focus: moderately to poorly differentiated ductal carcinoma (1.2 cm). The histologies of the invasive foci should be coded 8523/3 and 8500/3 respectively. To determine the number of primaries, does rule M11 apply which indicates this should be a single primary even though ductal with mucinous differentiation is not in Tables 1 or 2? Or does rule M12 apply because there is a difference in the third digit of histology and thus means this should be reported as a multiple primary case? |
For cases diagnosed 2007 or later, accession two primaries, ductal carcinoma with mucinous differentiation [8523/3] and ductal carcinoma, NOS [8500/3]. The steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Breast MP rules because site specific rules have been developed for this primary. Start at the MULTIPLE TUMORS module, rule M4. The rules are intended to be reviewed in consecutive order within a module. These tumors have ICD-O-3 histology codes that are different that the third (xxx) digit and are, therefore, multiple primaries. Ductal carcinoma with mucinous differentiation is not a specific type of ductal carcinoma identified in either Table 1 or 2. (To locate Tables 1 and 2, go to Breast under the Terms & Definitions section of the manual.) It is ductal carcinoma mixed with another type of carcinoma (mucinous carcinoma in this case) see Table 3. Rule M11 does not apply. |

20120063 | Reportability--Pancreas: Are neuroendocrine "tumors" reportable and are they synonymous with neuroendocrine "carcinoma"? See Discussion. | Example: Pancreatic mass that probably represents a neuroendocrine tumor is staged as cT2N0M0. | According to the World Health Organization (WHO) pancreatic neuroendocrine tumors (NET) are malignant. They are reportable.
For pancreas primaries, code NET, G1 (well differentiated) to 8240/3; NET G2 (moderately differentiated) to 8249/3; and nonfunctional NET, GI or G2 to 8150/3. The histology code for neuroendocrine carcinoma (NEC) is 8246/3, large cell NEC is 8013/3 and small cell NEC is 8041/3. |

20120035 | Reportability--Pancreas: What is the histology code if well differentiated pancreatic endocrine neoplasms (PanNETs) are reportable?
|
Pancreatic (neuro)endocrine neoplasms (PanNETs) are reportable. The correct histology code is 8240/3. The grade is coded as 1 [well differentiated].
