Reportability/Diagnostic Confirmation--Melanoma: Would a shave biopsy diagnosis of "highly suggestive of early melanoma", followed by a re-excision diagnosis of "no residual disease", be SEER reportable if the clinician referred to the case clinically as a melanoma? If so, what would the Diagnostic Confirmation be? See discussion.
Pathology report from a shave biopsy states: "...markedly atypical junctional melanocytic proliferation. Changes highly suggestive of early melanoma arising adjacent to superficial congenital nevus." The re-excision pathology report states "biopsy proven melanoma" in the "Clinical History" section of the report (which is a reference to the original shave biopsy). The re-excision final pathology diagnosis states "no evidence of melanoma." The physician states that he thinks this is a melanoma. Should it be reported? Should Diagnostic Confirmation be coded to 1 or 8?
The case is reportable because the physician documented a clinical diagnosis of malignant melanoma. Code the Diagnostic Confirmation field to 8 [Clinical diagnosis only (other than 5, 6 or 7)].
Scope of Regional Lymph Node Surgery: Should this field be coded to "unknown or not applicable" for all hematopoietic morphologies, brain primaries and unknown primaries?
For cases diagnosed 1/1/2003 and after: Code the Scope of Regional Lymph Node Surgery field to 9 [Unknown or not applicable] for all hematopoietic morphologies, brain primaries and unknown primaries. .
Grade, Differentiation--Lymphoma/Leukemia: What code is used to represent this field when the phenotype is combined B cell and T cell?
For cases diagnosed prior to 1/1/2010:Code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable]. There is no combination code for B cell and T cell. There is also no hierarchy established for choosing one code over the other. Therefore coding such a case as a pure B cell or a pure T cell would misrepresent the phenotype.
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.
EOD-Extension--Lung: Are "aortico-pulmonary window", "paratracheal space", and "subcarina" coded in the EOD extension field or in the EOD lymph node involvement field? See discussion.
Would a lung tumor that extends into the AP window be synonymous with extension into the mediastinum? If so, would this also apply to extension to subcarina, paratracheal space, and other such terms corresponding to areas listed in the mediastinal lymph node field under code 2?
For cases diagnosed between 1998-2003:
Extension into the aortico-pulmonary window, would be coded in the EOD-Extension field as 70 [mediastinal extension]. If the tumor extends into the paratracheal space, subcarina, or other areas listed under the code 2 in lymph nodes, code the EOD-Extension field to 70 to capture this type of involvement.
Histology--CLL/SLL: If a tissue diagnosis of "small lymphocytic lymphoma" is made six months after an initial blood diagnosis of "chronic lymphocytic leukemia" should the histology be updated from 9823/3 to 9670/3?
For cases diagnosed prior to 1/1/2010:Do not change the histology to small lymphocytic lymphoma (9670/3). The chronic lymphocytic leukemia has advanced/progressed and disseminated into other tissues from the blood during the last six months. If the patient presents with disease in the blood and/or bone marrow only, code to CLL. If a lymph node or other solid tissue is involved initially, code to SLL. For the case cited, the tissue involvement occurred six months after the initial diagnosis and the histology code is not changed to reflect the progression of disease.
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.
All Surgical Fields/Radiation Sequence with Surgery--Unknown Primaries: What codes are used to represent these fields for an unknown primary treated with a radical neck dissection followed by radiation therapy?
For unknown primaries treated with a lymph node dissection and diagnosed 1/1/2003 and after, code:
1) Surgery to Primary Site: 98 [All unknown and ill-defined disease sites, WITH or WITHOUT surgical treatment].
2) Scope of Regional Lymph Node Surgery: 9 [Unknown or not applicable].
3) Surgical Procedure of Other Site: 1 [Surgery to other site(s) or node(s), NOS; unknown if regional or distant].
4) Radiation Sequence with Surgery: 3 [Radiation after surgery]. Any planned surgical treatment is used to code radiation/surgery sequence (per CoC I&R).
Histology (Pre-2007)--Kidney: What code is used to represent the histology "renal cell carcinoma with granular cell morphology"? Kidney primary with diagnosis of renal cell CA with granular cell morphology. Do we code as granular cell carcinoma? Is the term "morphology" synonymous with "type"? See discussion.
Do we code this type of tumor as a granular cell carcinoma [8580/3]?
For tumors diagnosed prior to 2007:
Code the Histology field to 8320/3 [granular cell carcinoma]. Renal cell carcinoma is a non-specific term that has several specific cellular subtypes, one of which is granular cell [8320/3].
Note: Do not code to granular cell tumor [9580/3], which is not a histology related to renal cell carcinoma.
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.
Grade, Differentiation--Bone Marrow: Can we use the AJCC Cancer Staging Manual, which lists myeloma as a B cell neoplasm under non-Hodgkin lymphomas, to code Grade, Differentiation field for myeloma to B-cell (code 6)?
For cases diagnosed prior to 1/1/2010:
No. Myeloma is a malignancy of plasma cells. Plasma cells are the daughters of B cells. So technically it would be correct to call them B cell, but that is not common usage.
Cell marker (phenotype) should be coded in the Grade, Differentiation field for only leukemias and lymphomas, as classified in the ICD-O-3. In the ICD-O-3, myeloma is listed under Plasma Cell Tumors, not Lymphomas. When a cell marker is coded for a leukemia/lymphoma it should be coded only from pathology and/or cytology reports.
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.
EOD-Extension--Pancreas: How do you code extension when CT scan shows a mass in the head of the pancreas "encompassing" the hepatic branch of the celiac artery? See discussion.
We do not code the term "encompasses" as involvement. However, should we code this case as extension to the peripancreatic tissue, NOS or as unknown?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 40 [Extension to peripancreatic tissue, NOS]. There has to be extension to peripancreatic tissue if the mass encompasses the celiac artery.
