For cases diagnosed 1998-2003:

Code the EOD-Extension field to 20 [Involvement of two or more lymph node regions on the same side of diaphram]. The AJCC lists mesenteric as a core nodal region, but does not list retroperitoneal lymph nodes as a part of this region, so retroperitoneal is a separate region.

The EOD staging scheme for lymphoma uses lymph node REGIONS as the criteria for assigning the extension code. Use the AJCC Cancer Staging Manual as the definitive source for classifying lymph node regions, not the ICD-O-3. If it is a separate LN region per the AJCC, it is coded in the EOD as a separate region.

According to the AJCC curator, the nodal regions are defined in Kaplan's book on Hodgkin disease. Bilateral cervical, or axillary, or hilar, or pelvic, or inguinal nodes count as two regions. Mediastinal and para-aortic lymph nodes count as one region regardless of laterality as they are centrally located. A large mediastinal mass constitutes one region involved regardless of the size.

Code 8246 is correct when the mass/lesion is referred to as neuroendocrine "carcinoma" or NEC. Use code 8240 when the mass/lesion is referred to as a neuroendocrine "tumor" or NET G1. The difference is the word tumor versus carcinoma. Carcinoid is most often used interchangeably with neuroendocrine tumor and not with neuroendocrine carcinoma.

Well-differentiated neuroendocrine tumor (NET) of the stomach is reportable. The WHO classification of digestive system tumors uses the term NET G1 (grade 1) as a synonym for carcinoid and well-differentiated NET, 8240/3.

For cases diagnosed prior to 1/1/2010:No, it is not SEER reportable. The diagnosis of "evolving" multiple myeloma could represent a plasmacytoma, plasma cell dyscrasia or another lymphoproliferative disorder. Some of these histologies are SEER reportable, but some are not. Additional information would be needed to determine reportability. If you are unable to obtain more information, the case is non-reportable.

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.

See the SEER coding guidelines for breast, https://seer.cancer.gov/manuals/2018/AppendixC/Coding_Guidelines_Breast_2018.pdf Generally, codes C502 - C505 are preferred over C501. C501 would be preferred over C508. Apply these general guidelines when there is no other way to determine the subsite using the available medical documentation.

Table 1, Primary Site codes, in the breast solid tumor rules also provide helpful information for coding site.

Yes. Based on the information provided above, the in situ component is "mininmal" for the purpose of coding Breast CS Site Specific Factor 6. The phrase "no extensive intraductal component" suggests that there is some intraductal carcinoma present.

Code the CS Extension field to 01 [Papillary transitional cell carcinoma stated to be noninvasive]. Extension into bladder diverticula does not change the code. Diverticula are pouches in the mucosa (mucous membrane).

Assign as Stage IV as recommended by our expert hematological oncologist. This is a rare occurrence and this type of presentation does not fit the definition of intraocular extension. Stage IV is probably the best stage for this type of presentation, since there are two extranodal organs involved, even though they involve a bilateral site.

EOD Primary Tumor: 700

SS: 7 (Distant)

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Thrombocytopenia NOS is not a reportable diagnosis per Appendix F. Thrombocytopenia and Refractory Thrombocytopenia are not the same disease.

Thrombocytopenia is caused by a decreased number of platelets in the blood. Non-malignant causes include disseminated intravascular coagulation (DIC), drug-induced non-immune thrombocytopenia, drug-induced immune thrombocytopenia, hypersplenism, immune thrombocytopenic purpura (ITP), thrombotic thrombocytopenic purpura, and infections of the bone marrow.

The term "coagulable state" is not reportable. This is not a a neoplasm. The term means capable of coagulating or capable of becoming thick. There are neoplasms, such as polycythemia vera, in which the blood becomes thick; however, you must have an actual reportable diagnosis in order to accession the case.
