When coding the Covid testing results, does SEER have any guidance on whether or not at home tests fall within reportability? For instance, if a medical provider says pt tested positive on an at home test, do we record that?
When you have information about home COVID tests, record this information. For example, if the home test was positive record as follows: COVID-19 rapid viral antigen test POS 08/09/2022
2021 SEER Manual/Primary Site--Ovary, Fallopian Tube: What information takes precedence for coding the primary site in cases with high grade serous carcinoma that are clinically called ovarian but on pathology, the pathologist calls the primary site fallopian tube and the gynecology oncology/managing phsyician continues to call the cases ovarian. Both the ovary and tube are involved. Sometimes also referred to as "tubo-ovarian."
When the choice is between ovary, fallopian tube, or primary peritoneal, any indication of fallopian tube involvement indicates the primary tumor is a tubal primary. Fallopian tube primary carcinomas can be confirmed by reviewing the fallopian tube sections as described on the pathology report to document the presence of either serous tubal intraepithelial carcinoma (STIC) and/or tubal mucosal invasive serous carcinoma.
If there is no information about the fallopian tubes, refer to the histology and look at the treatment plans for the patient. If all else fails, you may have to assign C579 as a last resort. Use text fields to document the details.
For additional information, see the CAP GYN protocol, Table 1: Criteria for assignment of primary site in tubo-ovarian serous carcinomas.
Primary site/Histology--Peritoneum: What is the correct primary site code for peritoneal mesothelioma in a female? When I use C482, it seems that the fields are all geared towards primary peritoneal carcinoma with FIGO staging, etc.
For mesothelioma, NOS (9050) and epithelioid mesothelioma (9052) of the peritoneum for females, assign C481, C482, or C488 as appropriate based on the site of origin in the medical documentation. The Primary Peritoneal Ca schema is assigned and you will need to complete the SSDIs for FIGO staging, CA-125 PreTx Interpretation, and Residual Tumor Volume Post Cytoreduction.
If the histology is 9051 or 9053 with primary site of C481, C482, or C488 for females, the Retroperitoneum schema is assigned. The only SSDI for this schema is Bone Invasion.
MP/H Rules/Multiple primaries--Breast: Does breast Rule M10, 'Tumors that are lobular (8520) and intraductal or duct are a single primary" apply if you have two tumors in the same breast, one ductal and the other tubulolobular (8524) or are they separate primaries per Rule M12?
Apply Rule M10 to this case. Tubulolobular is now classified as a variant of lobular. Code to lobular, NOS (8520) because Tubulolobular does not have a specific ICD-O-3 code.
MP/H Rules/Multiple Primaries: Is this counted as one or two primaries?
Patient is diagnosed with SCC esophageal cancer. Work-up reveals a lung nodule. Lung FNA (cytology) is read by the pathologist as SCC, favor metastatic esophageal SCC. However, the managing physicians are treating the patient as two separate primaries.
If the patient is being managed and treated as a case of primary lung cancer, report the lung diagnosis as a separate primary.
EOD-Clinical Extension--Prostate: Note 8 of the clinical EOD scheme for prostate states, "B1, Small, discrete nodule(s)<1.5 cm, and B2 Nodule(s)>1.5 cm ... " Does Note 8 still apply for cases diagnosed 1998 or later?
For cases diagnosed 1998-2003:
Note 8 in the EOD scheme does not apply because nodule size does not apply in the 5th or 6th edition of TNM.
Diagnostic Confirmation--Prostate: How do we code this field when there is an elevated PSA, no other work-up and there is a clinical diagnosis of adenocarcinoma?
Code the Diagnostic Confirmation field to 5 [positive laboratory test/marker study] to indicate the diagnosis is based upon an abnormal PSA tumor marker if the physician uses the PSA as a basis for diagnosing prostate cancer.
Primary Site/EOD Fields--Head & Neck: In the absence of an actual resection and a pathologic evaluation of the affected area, would a laryngoscopy or CT scan provide a better assessment of the EOD and the primary site?
For cases diagnosed 1998-2003:
For Primary Site and EOD, CT information has higher priority than laryngoscopy. The CT scan gives a better picture of the involvement of the deeper tissues. A laryngoscopy falls into the "physical exam" category more than the "operative" category. The laryngoscopy report is not an "operative" report like those generated from a surgical procedure.
Reportability/Histology--Liver: Are primary hepatic neuroendocrine neoplasm and primary hepatic neuroendocrine tumor (PHNET) reportable? What are the specific histology codes?
Primary hepatic neuroendocrine tumor (PHNET) is reportable as are other digestive system NETs. There is no specific histology code for PHNET. We suggest you assign 8240/3. Use text fields to document the details.
Unless you can obtain clarification, do not report primary hepatic neuroendocrine neoplasm with no further information. If this term is being used as a synonym for PHNET, document this in the registry's policies and procedures, and report these cases.
