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.
Date of Diagnosis/Histology (Pre-2007)/Behavior--Melanoma: How are these fields coded when the first shave biopsy finds "what appears to be the top of a melanoma" and a subsequent shave biopsy finds "features consistent with lentigo maligna?"
For tumors diagnosed prior to 2007:
Evaluate each case using all available information, including all pathology reports. Use the date of the first biopsy because it did identify the melanoma. The second biopsy confirmed the histologic type.
According to WHO's Histological Typing of Skin Tumors, lentigo maligna melanoma is similar to lentigo maligna, but has dermal invasion by atypical melanocytes.
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.
Multiple Primaries--Urinary: How many primaries should be coded for an 8/9/07 invasive transitional cell carcinoma of right ureter; 7/9/08 non-invasive urothelial carcinoma of bladder; 11/18/08 non-invasive urothelial carcinoma of left ureter; 6/20/09 invasive urothelial carcinoma of left ureter?
One primary. This is a good example of how the field effect occurs in the urinary system. From 2007 to 2008, Rule M8 says bladder and ureter tumors are not new primaries and would be documented as recurrences. Because other urinary sites are involved by 11/08 and by 06/09, do not make second primary of left ureter (Rule M4 does not apply).
Recurrence (Pre-2007)--Colon: When there is no statement of recurrence on the abstract, is a colon tumor at the anastomosis site a recurrence of the previous colon cancer or a new primary?
For tumors diagnosed prior to 2007:
If the cancer at the anastamosis site is more than two months after the previous colon cancer, abstract as a separate primary.
If the cancer at the anastamosis site is within two months of the original diagnosis and the histologies are the same, do not abstract as a separate primary.
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.
EOD-Extension--Colon: What code is used to represent this field for a mid-ascending colon primary that invades through muscularis propria and into subserosal fibroadipose tissue that also presents with a "separate serosal nodule" of carcinoma within cecum that is consistent with a tumor implant (cT3, N0, M1)?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 85 [Metastasis], because the nodule of carcinoma in the cecum is not contiguous with the mid-ascending primary colon tumor.
Reportability/Terminology--Head & Neck: Is an "evolving" squamous cell carcinoma of the vermillion border of the left lower lip reportable?
For solid tumors, ignore the term "evolving" and apply the registry rules for reportability to this case. Squamous cell carcinoma of the vermillion border of the lower lip (C001) is reportable.
Histology--Lymphoma: How is "histiomonocytic lymphoma" coded?
For cases diagnosed prior to 1/1/2010:Assign code 9755 [Histiocytic sarcoma; True histiocytic lymphoma]. "Histiomonocytic" is not standard terminology, according to our expert consultant. However, 9755 is the best code to assign.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Code the histology to 9950/3 [polycythemia vera], the more specific histology, per Rule PH29. Myeloproliferative syndrome is a non-specific (NOS) histology and polycythemia vera is a specific type of myeloproliferative disease.
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.
Ambiguous Terminology/Reportability: Is the phrase "indicative of cancer" SEER reportable?
No. The phrase "indicative of cancer" alone is not a definitive cancer diagnosis. The word "indicative" is not on the list of ambiguous terms that is equivalent to a diagnosis of cancer.
MP/H Rules--Corpus uteri: How is histology coded for an endometrial tumor described as an "endometrioid adenocarcinoma with prominent squamous metaplasia"?
For cases diagnosed 2007 or later:
Endometrioid adenocarcinoma with squamous metaplasia is coded 8570 [Adenocarcinoma with squamous metaplasia]. This falls under the Histology Coding Rules for Other Sites, rule H17. The code for Endometroid adenocarcinoma is 8380. The code for Adenocarcinoma with squamous metaplasia is 8570. The histology with the numerically higher ICD-O-3 code is Adenocarcinoma with squamous metaplasia -- 8570.
