Primary Site/EOD-Size of Primary Tumor--Lung: If the only lung mass described in CXR is a "hilar mass," is the primary site coded to C34.9 [Lung, NOS] or C34.0 [Main Bronchus; incl. Carina]? Also, can the size of the hilar mass be used to code the size of tumor field?
Because the only description available is "hilar mass," code primary site as C34.0.
For cases diagnosed 1998-2003: Use size of mass for EOD-Size of Primary Tumor.
Reportability/Histology-Gallbladder: Is high grade biliary intraepithelial neoplasia of the gallbladder reportable?
High grade biliary intraepithelial neoplasia of the gallbladder is reportable. Assign code 8148/2. It is also known as biliary intraepithelial neoplasia grade 3, or BilIN-3.
MP/H Rules/Histology--Breast: Patient has single invasive left breast tumor diagnosed in 2008. Final pathology diagnosis is "Invasive solid papillary carcinoma". No mention of ductal in report. What is histology?
For cases diagnosed 2007 or later:
As of July 2010:
Code the histology 8503 [Infiltrating papillary adenocarcinoma].
This is solid papillary, not solid AND papillary carcinoma. Solid is an adjective modifying papillary, in other words, a subtype of papillary. We do not have a code for solid papillary, so we code to the NOS, papillary using rule H14.
Reportability/Terminology, NOS--Hematopoietic, NOS: Is "smoldering" multiple myeloma reportable to SEER?
For cases diagnosed prior to 1/1/2010:Yes, "smoldering" multiple myeloma is reportable to SEER as multiple myeloma [9732/3].
According to our pathologist consultant, "smoldering" multiple myeloma would certainly refer to a diagnosed process. Smoldering means the process is progressing, but perhaps slowly, or even at a slower pace than might be expected.
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-Size of Primary Tumor: Can you code the tumor size if you have the aggregate size given for two or more tumor masses?
For cases diagnosed 1998-2003:
No. Never code the aggregate size in the Size of Primary Tumor field when the pieces removed come from TWO OR MORE tumors. If there is a clinical statement regarding the size of two or more tumors, code this field to the size of the largest tumor.
The aggregate size can only be used to code the Size of Primary Tumor field when the PATHOLOGIST estimates the size of the tumor from the pieces of ONE tumor removed by the surgeon.
First course treatment/Immunotherapy--Prostate: Is XGEVA, given for bone mets from prostate cancer, abstracted as immunotherapy, or is it an ancillary drug and not recorded?
Do not record XGEVA when given for bone mets from prostate cancer. See SEER*Rx for more information.
First Course Therapy/Surgery of Primary Site--Prostate: What is the correct surgical code for irreversible electroporation ablation of the prostate diagnosed in 2021?
Assign code 17 for irreversible electroporation ablation of the prostate when there is no tissue submitted to pathology for a 2021 or 2022 case.
Multiple Primaries--Lymphoma: Is a diagnosis of mycosis fungoides followed a year later with a biopsy proven diagnosis of anaplastic large T-cell lymphoma stated to represent a transformation of the previous mycosis fungoides reportable as one or two primaries?
For cases diagnosed prior to 1/1/2010:
This is one primary. Code the histology according to the original diagnosis, mycosis fungoides. The physician states that this one disease process started as mycosis fungoides and progressed into lymphoma. A physician's statement has priority over other sources in determining the number of hematopoietic primaries.
In October 2006, a committee will begin working on multple primaries among hematopoietic diseases. The committee will provide further guidance on dealing with disease transformation and other issues.
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: Is there a physician priority list for coding primary site? For example, the surgeon states during a pancreatectomy that the primary is in body while the pathologist states in their synopitc report that primary is neck; neither is in agreement, or neither is available for confirmation.
As a general rule, the surgeon is usually in a better position to determine the site of origin compared to the pathologist. The surgeon sees the tumor in its anatomic location, while the pathologist is often using information given to him/her by the surgeon and looking at a specimen removed from the anatomic landmarks. However, when a pathologist is looking at an entire organ, such as the pancreas, he/she may be able to pinpoint the site of origin within that organ.
In the case of pancreas body vs. neck, the neck is a thin section of the pancreas located between the head and the body. It may be a matter of opinion whether a tumor is located in the "body" vs. the "neck." In the situation you describe, we would give preference to the surgeon and assign the code for body of pancreas, C251.
