Histology (Pre-2007)--Lung: What code is used to represent the histology "mucin-producing bronchoalveolar carcinoma?" Is mucin-producing synonymous with mucinous?
For tumors diagnosed prior to 2007:
Code histology as 8253 [Bronchiolo-alveolar carcinoma, mucinous]. Mucin-producing bronchoalveolar carcinoma is best classified in ICD-O-3 as Bronchiolo-alveolar carcinoma, mucinous.
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.
Date Multiple Tumors--Prostate: For a prostate biopsy done 10/20/08, both lobes involved with tumor, unknown how many tumors, what would be coded in date of multiple tumors?
In this case, code the date of the biopsy in Date of Multiple Tumors [10202008]. When the number of tumors is unknown, code the date of diagnosis as the Date of Multiple Tumors. This is the date on which it was determined that there were an unknown number of tumors. This instruction will be added to next edition of the MP/H manual.
Reportability/Behavior Code--Bone Marrow: Is T-cell large granular lymphocytic leukemia SEER reportable? Pages 102, 147, 156, 160-162 and 167 of the ICD-O-3 list it as 9831/1, but on page 17 this is listed as 9831/3.
For cases diagnosed prior to 1/1/2010:T-cell large granular lymphocytic leukemia [9831] is a very indolent form of leukemia. It was assigned a behavior code of 1 by the editors of ICD-O-3 (as noted on pages 102, 147, 156 160-162, and 167 of the ICD-O-3 manual). The table on page 17 is the World Health Organization list of hematopoietic and lymphoid tumors. WHO recognizes TCLGLL as a malignancy. The disease is infrequently symptomatic enough to be diagnosed. However, when any of the terms listed with code 9831 are described as malignant or aggressive, report to SEER as a malignancy with a behavior code of /3.
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.
Primary Site/CS Extension--Lymphoma: How should these fields be coded for a malignant lymphoma with spleen involvement, inguinal and iliac adenopathy, T12 lesion with bony destruction, and a paraspinal mass in lower lumbar region with extension into iliac fossa involving left psoas muscle and causing bony destruction?
For cases diagnosed prior to 1/1/2010, 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 primary site C496 [Connective, subcutaneous and other soft tissue of trunk]. When lymphoma is present in an extranodal organ/site and in that organ/site's regional lymph nodes, code the extranodal organ/site as the primary site. In this case, there is a soft tissue paraspinal mass at T12 extending into iliac fossa, left psoas muscle and bone. Lymph nodes are also involved. Assign CS extension code 21 [Direct extension to adjacent organs or tissues].
For cases diagnosed 1/1/10 and later, 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.
Histology (Pre-2007): What code is used to represent the histology "non oat cell carcinoma"?
For tumors diagnosed 2001-2006:
Code the Histology field to 8046/3 [non-small cell carcinoma] if the pathologist does not provide a more specific histologic type. "Non oat cell" is a synonym for "non-small cell."
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.
Histology (Pre-2007)--Melanoma: How is a 2004 "malignant melanoma, nodular type, epithelioid cell type" coded?
For tumors diagnosed prior to 2007:
Assign code 8771 [Epithelioid cell melanoma]. Code the cell type when specified.
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.
Tumor Size/Bladder: The 2018 SEER Coding and Staging Manual says to use imaging over physical exam as priority for determining tumor size. If a bladder tumor is 4 cm visualized on cystoscopy, and is 2.8 cm on CT scan, which should be used as the clinical size? Is cystoscopy (endoscopy) a clinical exam or imaging?
For the case described here, use the size from the CT scan. Physical exam includes what can be seen by a clinician either directly or through a scope. A tumor size obtained visually via cystoscopy is part of a physical exam. Therefore, the imaging (CT) tumor size is preferred. Use text fields to describe the details.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient with a several month history of refractory anemia with excess blasts (RAEB), that may or may not have been treated, who now presents with a bone marrow biopsy that is compatible with acute myeloid leukemia?
Per Rule M10, abstract multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm AND there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis. Two primaries should be accessioned for this case: refractory anemia with excess blasts (RAEB) [9983/3] (a chronic neoplasm), and acute myeloid leukemia [9861/3] (an acute neoplasm).
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
CS Eval--Ovary: How is CS Mets Eval coded when the patient has positive pleural effusion confirmed by cytology?
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 CS Mets Eval for the example above 3 [path exam of metastatic tissue] assuming there has been no pre-treatment. Positive cytology is required for confirmation of pleural effusion for an ovarian primary.
Surgical Procedure of Other Site--Pancreas: Should an embolization of liver metastasis for a pancreas primary be coded as treatment?
Code "embolization" (or hepatic artery embolization, HAE) to a metastatic site in Surgical procedure of Other Site. Assign code 1 [nonprimary surgical procedure performed].
This procedure was previously coded as other therapy, experimental. Code as surgery as of July 2005.
