Reportability--Hematopoietic, NOS: Is "evolving" multiple myeloma reportable to SEER?
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.
Scope of Regional Lymph Node Surgery: If a named regional lymph node is aspirated should this field be coded to 1 [Regional lymph node removed, NOS], as is stated on page 127 of the SEER Program Code Manual, or should this field be coded to a more specific code when that is available (e.g. Lung primary code 3 [Ipsilateral mediastinal and/or subcarinal nodes])?
For cases diagnosed 1/1/2003 and after: A generic scheme was created for the Scope of Regional Lymph Node Surgery field. As a result, there no longer are codes available that represent specific named lymph node chains. Code aspiration of a lymph node to 1 [Biopsy or aspiration of regional lymph node, NOS].
Histology (Pre-2007)--Bladder: What code is used to represent the histology "transitional cell and small cell carcinoma" of the bladder? See discussion.
Code 8045/3 is used for combination codes that represent a mixture of small cell carcinoma and any other carcinoma. When we use this histology code for bladder primaries with mixed transitional cell and small cell carcinoma, we encounter a problem with the SEER edits (site and morphology conflict).
For tumors diagnosed prior to 2007:
Please see SEER Inquiry question ID number 20041104.
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.
EOD-Extension--Lymphoma: What code is used to represent this field for an extranodal lymphoma that has more than one tumor in the primary site OR has intraluminal extension from the primary site to an adjacent organ? See discussion.
1. Small lymphocytic lymphoma with 2 tumors in the stomach.
2. Lymphoma involving the cecum and ileum.
3. Lymphoma of the fundus of stomach with extension into the esophagus.
For cases diagnosed 1998-2003:
Using the EOD scheme for lymphoma, code the Extension field to 11 [Localized involvement of a single extralymphatic organ or site; Stage IE] for all 3 of these cases.
For the stomach lymphoma: There are 2 areas of lymphoma, but it is still confined to one site.
For the other 2 lymphomas: Intraluminal (mucosal) spread of the lymphoma never equals extension. The same phrase that was added to code 21, "Direct extension to adjacent organs or tissues", will be added to code 11 in the Collaborative Stage System. Neither "mucosal spread to a contiguous organ" or "direct extension into a nearby organ" affect staging. Both are still coded to 11 as long as there are no other sites of lymphoma involvement.
EOD code 80 is poorly written. It does not mean diffuse invovement or multiple tumors in a single organ but rather "diffuse disease in two or more organs."
Multiple Primaries (Pre-2007)--Breast: Should just one primary be reported when only ductal carcinoma in situ is diagnosed initially but the mastectomy performed as part of the first course of cancer-directed therapy, but more than 2 months after diagnosis, contains a diagnosis of invasive ductal carcinoma? See discussion.
How do we code this case in light of the EOD guideline that states we include all information collected within 4 months of diagnosis or through the completion of first surgery in the absence of disease progression when coding.
For tumors diagnosed 1998-2003:
Report this case as one invasive primary, unless stated to be two primaries by the clinician. This appears to be a single primary with different behaviors, rather than separate tumors.
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.
Terminology/EOD-Extension--Prostate: How does SEER define the prostatic "apex"? See discussion.
Some pathologists define the prostatic apex as including the bottom third of the prostate whereas others regard only the bottom-most portion of the gland to be the apex.
SEER defines the apex as being the bottom-most portion of the gland. Apex means "narrowest part," which in the prostate would be the bottom-most portion of the gland.
Grade/Histology (Pre-2007)--All Sites: What code is used to represent these fields for the histology "High grade dysplasia (adenocarcinoma in situ)" or "AIN III/High grade AIN"?
For tumors diagnosed prior to 2007:
Code the Histology field for the first example to 8140/2 [Adenocarcinoma, NOS, in situ] and for the second example to 8077/2 [AIN, grade III]. For both of the cases code the Grade, Differentiation field to 9 [Cell type not determined not stated or not applicable]. The 6th digit (grade code) of ICD-O-3 describes how much or how little a malignant tumor resembles the normal tissue from which it arose. In contrast, "grade" is used in the examples above to describe the degree of dysplasia, from mild dysplasia (low grade) to severe dysplasia (high grade). Do not record the degree of dysplasia in the 6th digit grade field.
For tumors diagnosed 2007 or later, refer to the MP/H rules for histology coding instructions. 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.
EOD-Extension--Urinary Tract: Can the rules used to code bladder extension involving the term "no involvement of muscularis/and no mention of subepithelium/submuscosa" be used to code extension for other urinary tract primaries, such as ureter?
For cases diagnosed 1998-2003:
No. The inferred descriptions of noninvasion apply to bladder cases only.
Histology/Date of Diagnosis--Hematopoietic, NOS: What code is used to represent histology for a June 2001 diagnosis of "myelodysplastic syndrome" followed by a September 2001 bone marrow biopsy diagnosis of "myelodysplasia evolving into an acute leukemic state"?
For cases diagnosed prior to 1/1/2010:
Code the Histology field to 9989/3 [myelodysplastic syndrome] and the Date of Diagnosis field to June 2001.
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.
Multiple Primaries (Pre-2007)--Soft Tissue: Does SEER agree that one primary of the soft tissues of pelvis [C49.5] should be reported when a pathologic diagnosis for bilateral herniorrhaphies is "right and left inguinal hernias with low grade spindle cell sarcoma"?
For tumors diagnosed prior to 2007:
Yes. This is one primary and should be coded to C49.5 [Connective, subcutaneous and other soft tissue of pelvis]. According to Rule A in ICD-O-3, the type of tumor ("sarcoma") indicates origin from a particular tissue, resulting in the primary site code of C49.5 [Inguinal region, NOS] for this sarcoma.
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.
