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.
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.
First Course Treatment: What code is used to represent each treatment modality field when there is no indication that a particular modality of treatment was recommended or started?
Code the individual treatment fields to 0 or 00 [None] when the modality is not addressed in the treatment plan (or when a treatment plan is lacking) and there is no indication that a particular modality of treatment was recommended or started.
Grade, Differentiation--All Sites: If the grade given for the primary site is from a provisional diagnosis and the grade given for a metastatic site is from a final diagnosis, should we follow the SEER rule that says to code the grade as stated in the final diagnosis (e.g., Provisional diagnosis: High grade papillary serous carcinoma of ovary. Final dx: poorly differentiated adenocarcinoma in a caval lymph node)?
Code the Grade, Differentiation field to 4 [High grade] from the examination of the ovary (primary site). Do not code grade from a metastatic site.
Multiple Primaries (Pre-2007)--Bladder: Should an invasive malignancy following an in situ malignancy by more than two months be a new primary? Why? See discussion.
Example: An in situ bladder case was diagnosed and treated. Three months later another TURB diagnosed an invasive bladder carcinoma. Is the invasive case reportable to SEER as a new primary?
For tumors diagnosed prior to 2007:
Yes. These are two primaries.
In situ cancers are not included in SEER incidence rates. Incidence rates must correlate with mortality rates.
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--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.
Radiation/Chemotherapy: How do we code radiation and chemotherapy when the only statement we have is that the patient is "referred to either an oncologist or a radiation therapist"?
For cases diagnosed 1/1/2003 and after: A referral does not mean that the radiation therapy or chemotherapy was actually recommended. These cases need follow-back to see if treatment was recommended and/or administered. Some registries code these cases as 8 [Radiation recommended, unknown if administered] or 88 [Chemotherapy recommended, unknown if it was administered] and routinely review all cases with 8 or 88 codes. Upon review, the codes are updated depending on the information found. If there is no information available, the code 8 or 88 is changed to 0 or 00 [None].
Primary Site (Pre-2007)--Prostate/Prostatic Urethra: What code is used to represent primary site for an "adenocarcinoma with spindle cell differentiation" of the prostatic urethra?
For tumors diagnosed prior to 2007:
Code the Primary Site field to C61.9 [prostate] because the histology is adenocarcinoma.
When a malignancy is identified in the prostatic urethra, look at the histology to determine the primary site. If it is a transitional cell carcinoma, code the Primary Site field to C68.0 [urethra] and if it is an adenocarcinoma, code to C61.9 [prostate].
The EOD scheme is ultimately collapsed into the TNM scheme. The TNM system differentiates between adenocarcinoma of the prostate and transitional cell carcinoma of the urethra. Only adenocarcinoma of the prostate is staged by the prostate scheme. Transitional cell carcinoma of the prostatic urethra is coded to C68.0 [urethra] and staged with that scheme.
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.
Multiple Primaries (Pre-2007)--Testis: How many primaries should be reported when seminoma is diagnosed simultaneously in both testicles and both tumors are encapsulated?
For tumors diagnosed prior to 2007:
Report this cases as two primaries, unless there is information in the record confirming one primary.
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--Breast: Should clinically mentioned "thickening" of the breast be ignored if the pathology report does not mention thickening or skin involvement? See discussion.
For cases diagnosed 1998-2003: Can clinical "thickening" of the breast be coded to 20-28 extension code when there is no mention of the thickening or skin involvement in the pathology report? How do we code cases when pathology reports don't support the clinical finding of skin involvement.
For cases diagnosed 1998-2003: Do not use code 20-28 when there is no preoperative treatment and the pathology report does not confirm skin invasion. The clinical diagnosis of skin involvement was not supported by the pathology report.
