Histology (Pre-2007): What is the difference between code 8244/3 composite carcinoid (combined carcinoid and adenocarcinoma) and 8245/3 adenocarcinoid tumor?
For tumors diagnosed prior to 2007:
Assign code 8244/3 [composite carcinoid] when there is a combination of adenocarcinoma and carcinoid tumor.
Assign code 8245/3 [adenocarcinoid] when the diagnosis is exactly "adenocarcinoid."
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/In Situ--Prostate: Was there a time period when PIN III was reportable to SEER?
Per the 2004 SEER Manual, page 2, Reportable Diagnoses, Exceptions, 1.b.iii "Prostatic intraepithelial neoplasia (PIN III) of the prostate (C619). (Collection stopped effective with cases diagnosed 1/1/2001 and later.)"
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--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.
2004 SEER Manual Errata/Grade--Colon/Bones: Is the term "pleomorphic" used to code tumor grade to 3 for selected primaries?
Delete the row containing the word "pleomorphic" from the tables on pages 93, C-219 and C-411. This correction will be included in the next set of replacement pages for the 2004 SEER manual.
Grade, Differentiation/Priorities: Which has priority, the differentiation or the nuclear grade for a liver biopsy histology described as "well differentiated hepatocellular carcinoma, nuclear grade 3/4"?
For most sites, differentiation has priority over the nuclear grade when both are specified (excluding breast and kidney). Assign grade code 1 [well differentiated] to the example above.
Primary Site/CS Extension--Lymphoma: Should CS Extension be coded to 22 [Involvement of spleen PLUS lymph node(s) BELOW the diaphragm] or 32 [Involvement of spleen PLUS lymph node(s) on both sides of the diaphragm] for the biopsy proven lymphoma in a retroperitoneal mass and a CT of the chest with nodes described as "indeterminate" or "calcified"? See Discussion.
It was diagnosed on CT-guided biopsy of retroperitoneal mass: obtained access to the posterior aspect of the lesion adjacent to the left side of the spinal column at approx the level of the kidney.
CT Abdomen/Pelvis: Large low attenuation & smooth walled regions in hilum of the spleen & into the splenic parenchyma w/assoc smaller lesions in the spleen. Associated adenopathy on left side of aorta between the superior mesenteric artery & renal vein.
Body of report: Soft tissue mass 4.4 x 4.8 x 7cm adjacent to the left side of the aorta & spanning the distance betw superior mesenteric vein inferiorly to level of left renal vein, appears to be matted adenopathy.
CT Chest: indeterminate nodes in pretracheal region w/calcified nodes in infracarinal region, right perihilar region & calcifications in pulmonary parenchyma of right lung. Calcified nodes & other structures suggest healed granulomatous process. However, with the infarct/mass lesion in the spleen & left periaortic adenopathy, extension of this process to the mediastinum can't be excluded.
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 the primary site C772 [Intra-abdominal lymph nodes]. Assign CS extension code 22 [Involvement of spleen plus lymph nodes below diaphragm]. The description from the chest CT is not sufficient to code lymph node involvement above the diaphragm.
Reportability/AmbiguousTerminology: Because there is a caveat in the SEER PCM, 3rd edition to ignore adverbs such as "strongly" when assessing reportability, should a term such as "likely" cancerous be reportable given than the expression "most likely" cancerous is reportable?
"Likely cancerous" is NOT reportable.
The CoC, NPCR and SEER have agreed to a strict interpretation of the ambiguous terms list. Terms that do not appear on the list are not diagnostic of cancer.
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.
CS Tumor Size--Breast: Is the largest focus or the total area coded for tumor size in a patient presenting with "scattered foci of DCIS, largest focus measuring 0.6cm. DCIS spans a total area of 2.1cm."
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 the size of the largest focus in CS tumor size. Code the tumor size for this case as 006 (6mm or 0.6cm).
