Surgery of Primary Site--Brain and CNS: Is "debulking" of a primary brain tumor coded to 21 [subtotal resection of tumor] or 30 [gross resection of tumor]?
Assign code 21 [subtotal resection of tumor, lesion, or mass]. Debulking removes as much of the tumor volume as possible in cases where it is not possible to remove the entire tumor. Debulking should improve the effectiveness of subsequent radiation therapy and/or chemotherapy.
First Course Treatment--Liver: Given that agents can be used that are not chemotherapy drugs, how should treatment be coded for a procedure called a "chemoembolization" when the agent used is not documented?
This issue was discussed among the national standard setters and per the SEER website this issue has been resolved as follows: When "chemoembolization" is done but the agents used are not chemotherapy drugs, then treatment should be coded as "Other Therapy." See http://seer.cancer.gov/tools/codingmanuals/embolization.html
Update to current manual/Lymphovascular invasion: Are lymphvascular invasion and lymphvascular space invasion on a pathology report the same thing or do they describe different things?
We confirmed with our expert pathologist consultant that lymphovascular invasion and lymphovascular space invasion are synonymous.
First course of treatment/Radiation therapy--Kidney: Patient has a CT-guided biopsy of a right renal mass with procedure details under the Interventional Radiology Procedure Note stating "Gelfoam tract embolization." Is this particular embolization treatment?
Gelfoam tract embolization for a CT-guided renal biopsy is not treatment. It is a method to plug the biopsy track to reduce the risk of hemorrhage.
CS Site Specific Factor 4--Prostate: If PAP is not mentioned in the chart, should Site Specific Factor 4 be coded to 999 [unknown or no information] or 000 [test not done]?
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 tumors diagnosed 2004 only:
Code the CS Site Specific Factor 4 to 999 [Unknown or no information; Not documented in patient record]. If there is no report of a lab test in the health record, code as 999.
Code this field to 000 [Test not done] when there is a statement in the record that a test was not performed.
Tumors diagnosed 1/1/2005 forward no longer have PAP coded in the Site Specific Factor 4 field.
Code histology to 9691/3 [Follicular lymphoma, grade 2]. Nodular lymphoma is an obsolete term once used to describe follicular lymphoma. (See Appendix A, Table A3)

Reportability/Histology: Would a histology reading "Well-differentiated neuroendocrine neoplasm" of the appendix be reportable? Since the word "tumor NOS" and "neoplasm NOS" both code to 8000, I would assume they would be interchangeable but just wanted to verify.
According to SINQ 20130027 & 20140002 a "Well-differentiated neuroendocrine tumor" of the appendix IS reportable.
"Well-differentiated neuroendocrine neoplasm" of the appendix is reportable. According to the WHO classification of Digestive System Tumors, "Well-differentiated neuroendocrine neoplasm" of the appendix is synonymous with NET. WHO states on page 13 "The term 'neuroendocrine neoplasm' can be used synonymously with 'neuroendocrine tumor.'"
Neuroendocrine "tumor," or NET G1, is listed in the WHO classification as one of the malignant neoplasms of the appendix.
CS Extension: How is CS Ext coded for the following?
Rretroperitoneal primary
Cystic mucinous tumor with intraepithelial carcinoma
There is no CS Extension code for intraepithelial ca in the retroperitoneal scheme.
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.According to the American College of Surgeons I & R system, assign code 10 [confined to site of origin] for intraepithelial carcinoma of the retroperitoneum.
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.
