Reportability/Diagnostic Confirmation: If a physician signs a case out as "precancerous melanosis of the face" (8741/2) and there is no microscopic confirmation of the disease, is this a reportable clinical diagnosis?
This case is reportable because the diagnosis of precancerous melanosis was stated by a recognized medical practitioner. Precancerous melanosis meets the reportable diagnosis criteria (See 2007 SEER Manual page 1).
CS Tumor Size: Can an 'ulcerated mass' be used to code CS tumor size? See Discussion.
The CS Manual (p. 26, 4.a.) states do not code the size of the polyp, ulcer or cyst. However it states that a 'cystic mass' can be used to code TS if it is the only size given. Scopes Text: 'ulcerated' mass based at anal verge & ext 3-4 cm up into rectum.
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.Do not code CS Tumor size using the size of an ulcerated mass.
Ambiguous terminology/Reportability--Leukemia: Is a 'suspicious peripheral blood smear' the same as a suspicious cytology? See Discussion.
The final diagnosis on the path report for a peripheral blood smear is stated to be "suspicious for malignancy." The microscopic description states that the "lymphoid population raises the concern of chronic lymphocytic leukemia." Nothing further was done. Is this a reportable case? If so, should it be coded as a leukemia or a malignancy NOS?
For cases diagnosed prior to 1/1/2010:Do not accession a leukemia case based only on a "suspicious" peripheral blood smear. If a confirmed diagnosis, clinical confirmation or further information becomes available later, accession the case at that time.
For cases diagnosed 1/1/10 and later, 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.
MP/H Rules/Histology--Breast: What is the histology code for the following?
4/21/03 Left breast: infiltrating ductal carcinoma, grade 3 micropapillary type. Tumor size: 3.5 cms; deep margin negative. Skin, nipple & areola positive for invasive ductal carcinoma. Dermal lymphatic invasion by carcinoma breast. Extensive intraductal component absent. 6+/6. See Discussion.
How should histology be coded for a 2003 diagnosis and also for the same diagnosis in 2007 or later?
For a case diagnosed in 2003, code 8507/3 [Duct micropapillary carcinoma]. See Coding Complex Morphologic Diagnoses, revised August 2002, 3rd example on page 5 and page 3, #4.
For cases diagnosed 2007 or later, code 8507/3 [Duct micropapillary carcinoma]. Use rule H12.
MP/H Rules--Breast: What is the histology code for a breast tumor that is ductal ca with focal squamous differentiation? See Discussion.
SINQ 20021062 states for cases Dx'd prior to 2007, use 8570. Is 8570 also used when the squamous differentiation is focal?
For cases diagnosed 2007 or later, use rule H14 and code the histology 8500 [duct carcinoma]. Ignore histologies described as "focal," "focus," or "foci." This instruction will be added to the histology rules in the upcoming revision of the MP/H manual.
Ambiguous terminology/Reportability--Kidney: Is a case reportable if a biopsy diagnosis of "suggestive of oncocytoma, malignant neoplasm cannot be excluded" follows a CT scan that was read as "suspicious for carcinoma"? See Discussion.
Pt is nursing home resident. CT abdomen/pelvis shows a "mass in the right kidney, highly suspicious for renal cell carcinoma". CT-guided needle biopsy performed with final diagnosis: "Neoplasm suggestive of oncocytoma. A malignant neoplasm cannot be excluded." No other information is available.
This case is not reportable based on the information provided. The suspicious CT finding was biopsied and not proven to be malignant. "Suggestive of" is not a reportable ambiguous term.
Histology--Brain and CNS: How is histology to be coded for a pituicytoma WHO grade I, of the pituitary?
Assign code 9380/1 [glioma, borderline].
According to our pathologist consultant, the term pituicytoma is restricted to low-grade glial neoplasms of the neurohypophysis or infundibulum. The best category currently available for these is glioma.
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.
MP/H Rules--Lung: In reference to lung, SINQ 20071028 states "'nodule' is not an equivalent term for tumor, mass, lesion, or neoplasm." However, slide 5 for the MPH lung section of "Beyond the Basics" states "we use the words 'mass, nodule and lesion' interchangeably." Which is it?
For cases diagnosed 2007 or later:
For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging.
This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised.
