Reportability--Appendix: Are low-grade appendiceal mucinous neoplasms reportable?
For cases diagnosed prior to 1/1/2022
A low-grade appendiceal mucinous neoplasm (LAMN) is not reportable. The WHO classification designates LAMN with the behavior code /1 [uncertain whether benign or malignant].
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be accessioned when a patient was diagnosed in 2003 with malignant lymphoma, mixed cell type, follicular in the inguinal lymph nodes and was recently diagnosed with follicular lymphoma (by a neck lymph node biopsy) involving the neck and mediastinal lymph nodes?
This case should be accessioned as a single primary: malignant lymphoma, mixed cell type, follicular [9691/3] diagnosed in 2003. The following describes how this determination was made.
This case is one in which the terminology for follicular lymphoma has changed over time. In 2003, follicular lymphoma was classified as small cleaved cell, large cell, or mixed cell (both small cleaved and large cell). Those designations are no longer used. This disease process is currently classified as follicular lymphoma NOS, grade 1, grade 2 or grade 3. The change was simply a change in classification/terminology.
Appendix A, Table A3 (Obsolete Terms as Defined in ICD-O-3, Lymphoid Neoplasm Obsolete Terms) should be used to determine the current term when an obsolete term is known/given. Per the Table, "Mixed cell type follicular lymphoma" is currently known as "Follicular lymphoma, grade 2" and the correct histology code is 9691/3. This is the correct histology for the 2003 primary.
Per Rule M15, the histologies must be check in the Multiple Primaries Calculator to determine the number of primaries. Enter [follicular lymphoma, grade 2 (malignant lymphoma, mixed cell type, follicular)] for Histology Code 1 and [follicular lymphoma, NOS] for Histology Code 2. The result is "Same Primary." As a result, accession a single 2003 diagnosed primary with the histology follicular lymphoma, grade 2 [9691/3] when the patient is subsequently diagnosed with follicular lymphoma, NOS.

2018 EOD Primary Tumor/2018 EOD Mets--Lung: Is EOD Primary Tumor coded to 500 and EOD Mets 10 when there are bilateral lung nodules with nodules in same lobe as the primary tumor? How is EOD Primary Tumor coded when separate tumor nodes are in an ipsilateral lung but there is no documentation as to whether it is in the same or different ipsilateral lobe from the primary tumor?
Assign 999 to EOD Primary Tumor if this is the only information you have for your case.The mention of nodules does not automatically mean that you have separate tumor nodules. There are many reasons for the appearance of nodules in the lung, some of which are not due to cancer. Unless you have further information on whether the physician has determined that they are related to the lung cancer, then assume that they are not related.
Assign 00 to EOD Mets. Do not code EOD Mets to 10 since you cannot determine whether those nodules are based on the tumor or not.
If you are able to obtain more information, then you can update the EOD Primary Tumor and EOD Mets.
Regarding the second question, if separate tumor nodules are noted, you cannot assume that they are due to tumor. Further information, or clarification, is needed on whether the separate tumor nodules are related to the lung cancer. Without further information, code EOD Primary Tumor to 999.
Histology (Pre-2007): What code is used to represent the histology "PD infiltrating duct ca with focal sarcomatoid pleomorphic features?"
For tumors diagnosed prior to 2007:
Code histology as 8500/33 [Infiltrating duct carcinoma, poorly differentiated]. "Features" is a term from the list indicating a majority of the tumor, however; in this case "features" is modified by "focal" which does not indicate a majority of the tumor.
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.
CS Lymph Nodes/Scope of Regional Lymph Node Surgery--Prostate: When prostate cancer is an incidental finding at cystoprostatectomy for bladder cancer, is the pelvic lymph node dissection coded for the prostate as well as the bladder?
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 pelvic lymph node dissection is coded as regional lymph node surgery for both primaries and the nodes are counted in collaborative staging for both primaries. The examination of the pelvic lymph nodes is relevant to both the bladder and the prostatic primaries.
Reportability: Is a tubular adenoma reportable if the final diagnosis is "high grade atypia" and the diagnosis comment is "atypia limited to muscularis mucosa areas of pseudostratification [formerly qualifying for carcinoma in situ]"?
This case is not reportable.
The pathologist would need to include "carcinoma in situ" as part of the final diagnosis in order for this case to be reportable.
CS Site Specific Factor 1--Colon: If the registrar did not support the CEA code recorded with the appropriate text documentation, should the central registry accept the registrars coding or change the value to 999?
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.Accept your registrars' codes at your discretion. It is encouraged, but not required, to enter text for CS data elements. These cases do not automatically default to code 999.
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.
