MP/H Rules/Histology--Breast: How is histology coded for an "infiltrating papillary carcinoma" of the breast when there is no mention of ductal or adenocarcinoma in the pathology report?
For cases diagnosed 2007 or later, assign histology code 8503 [Papillary adenocarcinoma]. Rule H14 applies.
ICD-O-3 code 8050 does not apply in this case. Refer to the numeric listing in ICD-O-3. 8050 is a squamous cell neoplasm. Papillary carcinoma of the breast is NOT a squamous cell neoplasm. It is a neoplasm of the breast parenchyma - ducts, lobules or connective tissue. 8503 is the correct code in this case.
Histology--Heme & Lymph Neoplasms: Is follicular lymphoma, high grade synonymous with grade 3 lymphoma [9698/3] or is the "high grade" ignored and the histology coded to follicular lymphoma, NOS [9690]?
Code histology to 9698/3 [follicular lymphoma, grade 3].
Follicular lymphoma, high grade is listed under the Alternate Names section of the Heme DB for Follicular lymphoma, grade 3.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
Radiation Therapy--Prostate: Is the regional treatment modality XRT best coded to 50 (brachytherapy, NOS), 53 (LDR) or 54 (HDR) when the documentation indicates only "I-125 seeds" to the prostate?
Assign code 53 [Brachytherapy, interstitial, LDR] for seeds to the prostate. Seeds are always low dose because they are left in place and the radioactivity decays over time.
Histology (Pre-2007)--Breast: What code is used for histology "tubular carcinoma with lobular carcinoma in situ"?
For tumors diagnosed prior to 2007:
Assign code 8211/3 [Tubular carcinoma]. According to histology rule #2 for a single tumor on page 86 of the 2004 SEER manual, code the invasive histology when both invasive and in situ tumor are present.
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.
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.
Histology (Pre-2007)/Diagnostic Confirmation: What code is used to represent the histology that initially presents on uterine curettage as a hydatidiform mole and after pulmonary metastases develop a month later, the clinical diagnosis is "metastatic gestational trophoblastic disease"?
For tumors diagnosed prior to 2007:
Code the Histology field to 9100/3 [Choriocarcinoma]. Gestational trophoblastic neoplasia includes the diagnosis of choriocarcinoma.
Code the Diagnostic Confirmation field to 8 [Clinical diagnosis only] based on the information above. However, if imaging, direct visualization, or another method identified the pulmonary metastases, then code the Diagnostic Confirmation accordingly.
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 Eval--Ovary: How is CS Mets Eval coded when the patient has positive pleural effusion confirmed by cytology?
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.Code CS Mets Eval for the example above 3 [path exam of metastatic tissue] assuming there has been no pre-treatment. Positive cytology is required for confirmation of pleural effusion for an ovarian primary.
EOD-Extension--Corpus uteri: How should EOD extension be coded when the pathology report shows adenocarcinoma arising in the endometrium with the statement "no invasive carcinoma identified?"
For cases diagnosed 1998-2003: Code endometrial cancer with no invasion to EOD extension code 11 [Confined to endometrium (stroma)]. "No invasion" most likely means no invasion of the myometrium.
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.
CS Extension--Ovary: What code is used to capture omental caking?
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.The term "omental caking" refers to a thickened omentum. In the case of ovarian cancer, omental caking is always indicative of involvement of the omentum. The omentum is an abdominal structure for the purposes of CS extension. Assign the appropriate code between 70-73.
When the size of implants is not stated, but operative report and scans state omental caking, code 71 would be best. When there are no size measurements on the operative report or scan or elsewhere, there is not enough information to assign 72. The choice of code between 70 and 73 will depend on the details of the specific case.
