CS Reg LN Pos/Exam--Colon: For a patient with both a prostate and colon primary, if the pathology report indicates that 2 of the 3 regional lymph nodes to the colon are positive for a prostate malignancy, how should these fields be coded for the colon primary?
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.For the colon primary, code Reg LN Pos 00 [all nodes negative]. Code Reg LN Exam 03 [three nodes examined].
Three lymph nodes were examined and found to be negative for metastatic colon cancer.
First Course Treatment/Surgery of Primary Site--Lung: How is radiofrequency ablation for lung primaries coded?
Assign code 15 [Local tumor destruction, NOS] in the Surgery of Primary Site field. RFA is a technique where a probe placed in or near a tumor sends radio waves into the tumor, causing it to heat up and kill the cancer cells. RFA doesn't fit neatly into code 12 or 13, so we are left with the NOS code.
Histology (Pre-2007)/Diagnostic Confirmation: Which histology code is preferred if the CBD brushing is positive for malignant cells, cytologically most consistent with ductal adenocarcinoma [8500/3], and the common hepatic artery lymph node biopsy has metastatic adenocarcinoma, consistent with cholangiocarcinoma [8160/3]?
For tumors diagnosed prior to 2007:
Assign histology code 8160 [Cholangiocarcinoma]. Code from the pathology specimen when available. In this case, the only pathology is from the lymph node specimen.
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 histology coded if the final diagnosis is "melanoma" and only in the comment section of the pathology report is there an indication of "Type: Lentigo Maligna. Cell Type: Small Cell"?
For tumors diagnosed prior to 2007:
Code the histology as 8742 [lentigo maligna melanoma]. Code the specific histologic type, even if stated only in the comment section.
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.
Primary Site--Sarcoma: What is the correct topography code for a partial lung lobectomy with pathology diagnosis of "pulmonary sarcoma with smooth muscle differentiation"? See Discussion.
Operative report: palpable 2x2cm mass in the mediastinal surface of the rt middle lobe and the contiguous upper lobe together.
Path comment after partial lung lobectomy: In all likelihood this is a malignant process occurring in smooth muscle changes surrounding vessels within the lung versus an undifferentiated epithelial tumor.
ADDENDUM DX: low grade pulmonary sarcoma with smooth muscle differentiation.
Consultant's report concurs with that of the original pathologist's report of malignant neoplasm compatible with smooth muscle origin.
This case is unique. Assign topography code C493 [Connective, subcutaneous and other soft tissue of thorax]. Based on the information provided, this sarcoma has smooth muscle differentiation and originated in the muscle. Code the primary site to muscle.
First Course Treatment--Prostatic Urethra: Is Lupron coded for a papillary carcinoma of the prostatic urethra that is treated with a TUR with fulguration and beam radiation even though the prostate biopsies are negative?
Do not code lupron as treatment for a primary in the prostatic urethra.
CS Site Specific Factor--Lymphoma: Can the International Prognostic Index (IPI) score be taken from a TNM form in the record? If so, what score would we code for "low" (0-1 points) and "high" (4-5 points)?
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.Yes, the IPI score from the TNM form can be used to code SSF 3. Without further information, code "low" as 000 [0 points]. Code "high" as 004 [4 points].
Date of Diagnosis--Sarcoma: Should the date of diagnosis be coded to the date of biopsy or the date of birth for an infant biopsied at 3 days of age and stated to have a diagnosis of congenital alveolar rhabdomyosarcoma, widely metastatic?
Code the date of the biopsy as the date of diagnosis. This is the date the cancer was first identified by a medical practitioner.
Note: SEER collects the Month and Year of diagnosis. The "day" of diagnosis is not collected by SEER.
Reportability--Brain and CNS: Does a case of astrogliosis meet the criteria for gliomatosis cerebri? See Discussion.
Case clinically stated to be a glioma of the brain. Pathology from resection states astrogliosis.
Anderson's Pathology defines astrogliosis as astrocytic proliferations. Gliomatosis cerebri is defined as diffuse neoplastic transformation of poorly differentiated astrocytes over a wide area; predominantly invovles hemispheric white matter.
The pathologic diagnosis for this case, astrogliosis, is not reportable to SEER. Take the definitive diagnosis for this case from the pathology report from the resection. The pathology report takes precendence over the clinical diagnosis.
