Flag: For cases diagnosed prior to 2001, how is the ICD-O-3 Conversion Flag set if the ICD-O-2 and ICD-O-3 histology and behavior fields are both directly coded, as registrars in this region are instructed to do when submitting late cases, and as a result no conversion is necessary? Is it to 0 [Morphology (Morph--Type&Behav ICD-O-3 originally coded in ICD-O-3)] or Blank [Not converted]?
Assign code 3 [converted with review].
In your scenario above, ICD-O-2 and ICD-O-3 are being independently coded which should yield the same result as converting the case and then reviewing it.
Otherwise, if there is an ICD-O-3 code which differs from the ICD-O-3 code based on the conversion criteria, it will trigger an edit.
First course treatment: When a patient has a Haplo bone marrow transplant, is this coded as an allogenic bone marrow transplant since part of his marrow was used in addition to a donor?
Use code 12 in the Hematologic Transplant & Endocrine Procedures data field. Per the NCI, this procedure is an allogeneic transplant.
Rather than wiping out a patient’s immune system before transplanting donor bone marrow, doctors administer just enough chemotherapy to suppress the immune system, which keeps patients from rejecting the donated marrow without harming their organs. The procedure requires just a half-match, meaning that a patient’s parents or children could be suitable donors. AKA: Half-match transplants.
CS Lymph Nodes--Melanoma: If the primary site is coded to C449 because no primary skin lesion is identified for a melanoma case, are any positive lymph nodes assumed to be regional?
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 Nodes field to 80 [Lymph Nodes, NOS].
Although it is in the CS LN field, use the code for Lymph Nodes, NOT OTHERWISE SPECIFIED when you don't know whether the nodes are regional or distant. There are separate codes to use when you definitely know that the nodes are regional.
Reactive plasmacytosis is not reportable unless there is another indication of a reportable neoplastic disease. Reactive plasmacytosis is "a well known pathological process described as occurring in a variety of situations including infections, autoimmune disease, diabetes mellitus, sideropenia, liver cirrhosis and neoplastic conditions including leukemia. This process, by definition, is assumed to be a reaction of the immune system to an unknown or poorly defined stimulus." Based on this definition, reactive plasmacytosis is not the same as a plasmacytoma, although it may indicate the presence of a neoplastic process, such as leukemia.

2021 SEER Manual/Surgery of Primary Site--Lung: What is the correct surgery code for a left upper lobe (LUL) wedge resection (confirming adenocarcinoma) followed by a lingular-sparing LUL lobectomy and mediastinal lymph node dissection? Is the correct Surgery Code 22 since the lingula was not resected (not the whole LUL Lung)? Or should the appropriate surgery code be 33 (this surgery suffices to code to a lobectomy with the mediastinal lymph node dissection)?
Assign code 22 for LUL wedge resection followed by a lingular-sparing LUL lobectomy and mediastinal lymph node dissection. Code the lymph node surgery in Scope of Regional Lymph Node Surgery. We obtained input from an expert who agrees with this code. He states a lingula-sparing lobectomy is best coded as a segmentectomy because it is the same as an apical trisegmentectomy.
EOD-Size of Primary Tumor: How is tumor size coded when there is a clinical tumor size, the excisional biopsy pathology report has a tumor size and the resection specimen has residual tumor, but there is no tumor size provided in the pathology report?
For cases diagnosed 1998-2003: Code the EOD-Size of Primary Tumor from the excisional biopsy. If there is some indication that a large amount of tumor was removed at the time of the resection, code the clinical size instead. When both an excisional biopsy and a resection show tumor, code the largest size of tumor reported.
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.
Grade, Differentiation--Bladder: If the only indication of grade for a bladder primary is "grade 2, NOS," and we do not know the grading system being used by the pathologist, is the numeric grade 2 coded?
See the General Coding Rules on page 92 of the 2004 SEER Manual for instructions about coding grade.
If the only information available is "Grade 2," assign code 2 [Grade II].
Reportability--Brain and CNS: Is Langerhans cell histiocytosis [9751/1] of the meninges [C709] reportable?
For cases diagnosed prior to 1/1/2010:Yes. The criteria for reportable benign/borderline CNS tumors is based on location (site) and behavior (benign/borderline). There is no caveat for histologic type. Therefore, this would be reportable as these tumors have been reported arising from the meninges or choroid plexus.
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.
