Marital Status: Is marital status coded to 2 [married] if the patient is legally married to a same-sex spouse (e.g., patient has a Canadian spouse and in Canada, same-sex marriages are legal)?
Code marital status for same-sex persons based on the legal status. For the case example above, assign code 2 [married].
CS Reg LN Pos/Exam: Are lymph nodes coded as positive or negative when the pathology report for a lymph node dissection performed after radiation and chemo reveals that the nodes are negative but they demonstrated previous involvement by cancer? See Discussion.
Scenario: The patient was treated with radiation and chemotherapy prior to resection for esophageal cancer. The pathology report stated, "1/3 nodes c/w treated previous ca."
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.Record lymph nodes that are pathologically confirmed as positive in Regional Nodes Positive. Evidence of previous involvement by cancer is not recorded in this data item.
In the above scenario, the lymph nodes are negative according to pathology.
Clinically positive lymph nodes are coded in CS Lymph Nodes.
CS Extension--Pancreas, Head: When a tumor is described as having "vascular encasement of the celiac artery", is extension coded to 68 [tumor is inseparable from the celiac axis]?
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 vascular encasement of the celiac artery to CS extension code 68 [tumor is inseparable from the celiac axis].
This celiac axis is a small (1cm) area of branching arteries. The celiac artery branches into hepatic, gastric, and splenic at the axis. Dissecting tumor out from around the celiac axis is very tricky and usually encasement by tumor is a sign of inoperability.
Histology--Hematopoietic, NOS: How is an "advanced MDS (RAEB-T)/emerging AML" coded when discovered on a bone marrow biopsy?
For cases diagnosed prior to 1/1/2010:Code histology to 9984/3 [RAEB-T]. This particular MDS is refractory anemia with excess blasts in transformation. It has not yet progressed to acute myeloid leukemia.
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.
CS Extension/CS Mets at Dx--Corpus uteri: Is a microscopic metastasis in a cul-de-sac implant more appropriately reflected in the CS Extension field code 80 [Further contiguous extension; cul-de-sac] or in the CS Mets at Dx field code 40 [Distant metastasis]?
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.Assign code 80 [Further contiguous extension; Cul de sac] for CS extension in this case. Endometrium and ovary are exceptions to the rules that only contiguous extension is coded in Extension code 80. Only true distant metastases are coded in Mets at Dx.
2004 SEER Manual Errata/Surgery of Primary Site--Lymphoma: Item 9.a on page 178 is incorrect. Do not assign surgery code 98 to lymphoma, primary in lymph nodes. See Appendix C, page C-707 for Lymphoma (primary in lymph nodes) surgery codes.
Delete item 9. a. i. ii. and iii. on page 178 of the 2004 SEER Manual. This correction will be included in the next errata.
Primary Site--Peritoneum: During a second look staging lap following a diagnosis of serous carcinoma of the left ovary, did the physician correctly indicate a new peritoneum, NOS primary for disease described as an endometrioid adenocarcinoma in a "paracaval cyst" that appears to have arisen in endometriosis?
The primary site is C482 [Peritoneum, NOS]. "Paracaval" means alongside or near the vena cava.
Code the site in which the primary tumor originated.
CS Reg LN Pos/Exam--Colon: For a patient with both a prostate and colon primary, if the pathology report indicates that 2 of the 3 regional lymph nodes to the colon are positive for a prostate malignancy, how should these fields be coded for the colon primary?
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.For the colon primary, code Reg LN Pos 00 [all nodes negative]. Code Reg LN Exam 03 [three nodes examined].
Three lymph nodes were examined and found to be negative for metastatic colon cancer.
