Reportability/Histology--Endometrium: Is endometrial hyperplasia with atypia equivalent to atypical hyperplasia of the endometrium (8380/2) and thus reportable?
Endometrial hyperplasia with atypia is equivalent to atypical hyperplasia of the endometrium (8380/2) and thus reportable for cases diagnosed 2021 and later. Our expert pathologist consultant confirmed this for us.
EOD-Clinical Extension/EOD-Lymph Nodes--Prostate: How do you code clinical extension and lymph nodes for path only prostate cases treated with a TURP? Would clinical extension be coded to unknown or localized, NOS?
For cases diagnosed 1998-2003: Code the EOD-Clinical Extension field to 30 [localized, NOS] and the EOD-Lymph Nodes field to 0 [no lymph node involvement]. Per Note 7: Use code 30 when there is insufficient information as to whether the tumor is clinically apparent or inapparent but the tumor is confined to the prostate. This is an example of a case where there is insufficient information as to whether the tumor is clinically apparent or inapparent. Assume the tumor is confined to the prostate.
Histology (Pre-2007)--Melanoma: How is histology coded for a final pathology diagnosis of "malignant melanoma, NOS" that is clinically described as a nevus?
For tumors diagnosed prior to 2007:
Code 8720 [malignant melanoma]. Assign the histology code based on the histology stated in the final diagnosis on the pathology report. The pathology report must say melanoma arising in junctional nevus to use the code 8740/3 [Malignant melanoma in junctional nevus].
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.
MP/H Rules/Histology--Bladder: What is the correct histology code for a diagnosis of urothelial plasmacytoma carcinoma of the bladder per pathology report?
Assign code 8120/3, urothelial carcinoma, NOS, to urothelial plasmacytoma carcinoma of the bladder. The WHO classification describes plasmacytoid variants of urothelial carcinoma. There is no specific ICD-O-3 code for these variants; however, and 8120/3 must be used.
Histology (Pre-2007)--Breast: What code is used to represent the histology of "invasive ductal carcinoma and in situ ductal carcinoma, cribriform type"?
For tumors diagnosed prior to 2007:
Code the Histology field to 8500/3 [ductal carcinoma] unless the combination is ductal and lobular.
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.
First course treatment/Other therapy--Skin: How is PUVA [psoralen (P) and long-wave ultraviolet radiation (UVA)] coded when used for skin primaries such as melanoma and mycosis fungoides?
Code PUVA as "Other treatment" with Code 1 - Other. We do not have a code specifically for ultraviolet radiation.
Reportability/In situ--Prostate: Has there been a change in reportability for prostatic intraepithelial neoplasia (PIN III) (C619)? The 2018 SEER Manual notes: Collection stopped effective with cases diagnosed 01/01/2001 and later; however, on the casefinding list effective 10/01/2019, code D07.5, carcinoma in situ of prostate, is listed as reportable.
PIN III is not reportable in accordance with the 2018 SEER Manual; however, carcinoma in situ of the prostate is reportable as they represent different histology codes. The casefinding list is used to search for reportable cases and is not the same as a reportable list.
EOD-Size of Primary Tumor--Lung: Can tumor size of 002 [Malignant cells present in bronchopulmonary secretions] be used when there is a lung mass seen but the diagnosis is from a positive bronchopulmonary secretion?
For cases diagnosed 1998-2003:
EOD-Size of Primary Tumor code 002 [Malignant cells present in bronchopulmonary secretions] is used only when there is no visible primary lung tumor and bronchopulmonary secretions are positive for lung malignancy.
Even if the diagnosis was made by cytology of broncho-pulmonary secretions, if there is a visible mass, code the size of the mass if known, code 999 if size is unknown.
First course treatment--Heme & Lymphoid Neoplasms: Why isn't darbepoietin coded as treatment for hematopoietic diseases?
Darbepoietin is a synthetic form of erythropoietin. It stimulates erythropoiesis (increases red blood cell levels) and is used to treat anemia, commonly associated with chronic renal failure and cancer chemotherapy.
Darbepoietin is a support medication; it does not treat cancer. It is used to treat anemia caused by cancer directed chemotherapy treatments. It is not indicated for patients with myeloid cancers; cancers that originate in the bone marrow like leukemia.
Darbopoietin is an ancillary drug and is not coded as treatment.
Diagnostic confirmation--Heme & Lymphoid Neoplasms: Is Diagnostic Confirmation coded as 5 (positive laboratory test/ marker study) or code 8 (clinical diagnosis only) for a case that has a positive JAK2 mutation, and based on the results of the JAK2, the physician diagnosed the patient with polycythemia vera? There were no blood smears or bone marrow biopsies done.
Assign diagnostic confirmation code 5 for a positive laboratory test/marker study. A note was added to the Hematopoietic manual to state that code 5 now includes cases with no histological confirmation but there is positive immunophenotyping or genetic studies.
