CS Extension--Bladder: How is extension coded if the bladder tumor involves the right ureter per cystoscopy but the TURB specimen demonstrates muscularis propria invasion?
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 extension based on the area of deepest invasion. According to the TNM Supplement, which was used as a resource in the development of CS, "Direct invasion of the distal ureter is classified by the depth of greatest invasion in any of the involved organs." Record the greatest extent of disease using both clinical and operative/pathologic assessment.
Reportability/Histology--Tongue: Is high grade squamous dysplasia of the tongue reportable; and is it the same as carcinoma in situ (CIS), code 8077/2?
High grade squamous dysplasia of the tongue is reportable as of 2021 and later as 8077/2.
Histology/Primary site--Heme & Lymphoid Neoplasms: How are the histology and primary site coded if a pleurocentesis is compatible with plasmablastic plasmacytoma/lymphoma when no further information is available?
Code the histology to 9735/3 [plasmablastic lymphoma] and the primary site to C809 [unknown] per Rule PH27.
Code the histology specified when the only histology for the case is preceded by ambiguous terminology. For this case, code the histology to plasmablastic lymphoma because it is the only histology mentioned in the diagnosis.
Per the Heme DB Abstractor Notes section for plasmablastic lymphoma, most patients present with Stage III-IV disease. The positive pleural fluid is likely due to advanced disease. In the absence of any other information for this case, Rule PH27 applies, "Code primary site to unknown primary site C809 when there is no evidence of lymphoma in lymph nodes AND the physician documents in the medical record that he/she suspects that the lymphoma originates in an organ(s) OR multiple organ involvement without any nodal involvement."

Reportability--Gallbladder: Is high grade biliary intraepithelial neoplasia of the gallbladder reportable?
High grade biliary intraepithelial neoplasia of the gallbladder is reportable. Assign code 8148/2. It is also known as biliary intraepithelial neoplasia grade 3, or BilIN-3.
Histology--Leukemia: How is a "plasmacytoid dendritic cell leukemia/lymphoma" coded when it is discovered on a bone marrow biopsy for a patient who presented with multiple enlarged lymph nodes and the discharge diagnosis was Type 2 plasmacytoid dendritic cell leukemia?
For cases diagnosed prior to 1/1/2010:
The best code currently available for this entity is 9727/3 [precursor cell lymphoblastic leukemia].
The WHO classification refers to this as "Blastic NK-cell lymphoma." The 2005 WHO-EORTC classification for cutaneous lymphomas states that blastic NK-cell lymphoma may be derived from a plasmacytoid dendritic cell precursor. They suggest more appropriate terms for this condition may be "CD4+/CD56+ hematodermic neoplasm," and "early plasmacytoid dendritic cell leukemia/lymphoma." According to WHO, this is a rare form of lymphoma.

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.
Surgery of Primary Site--Breast: How is this field coded for a BILATERAL nipple sparing mastectomy given that SINQ 20110094 indicates that a nipple sparing mastectomy should be coded to 30 [subcutaneous mastectomy] but there is no code for bilateral subcutaneous mastectomies?
The Surgery of Primary Site field reflects the type of surgery performed on the primary site. In this case, a nipple sparing mastectomy should be coded to 30 [subcutaneous mastectomy]. If the details of the case indicate this is a single primary involving both breasts, code removal of involved contralateral breast under the data item Surgical Procedure/Other Site.
The diagnosis of "myelodysplasia" is not reportable.
Myelodysplasia covers a group of disorders that result in the inability to produce enough healthy mature blood cells. Those disorders include: anemia, leukopenia, thrombocytopenia, MDS, refractory anemia, refractory anemia with excess blasts in transformation, refractory anemia with ring sideroblasts, refractory anemia with excess blasts, chronic myelomonocytic leukemia, acute myeloid leukemia. Follow-back to the physician is necessary to determine whether or not a particular case represents a malignancy.
"Myelodysplasia" is also listed in Appendix F: Non-Reportable List for Hematopoietic Diseases.

CS Extension/EOD Extension--Renal Pelvis: Primary site is renal pelvis with direct extension to the rt adrenal gland. What is the correct extension code?
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.
Assign CS Extension code 67 [Adrenal gland from renal pelvis] for adrenal extension from renal pelvis -- T4 and regional direct extension.
MP/H rules/Histology--Breast: How many primaries and what histologies are coded for a left breast when a bi-lumpectomy path reveals one tumor with a microscopic focus of mucinous adenocarcinoma and extensive DCIS and a second .9 cm mucinous adenocarcinoma with extensive DCIS, and the subsequent mastectomy reveals foci of residual DCIS and Paget's disease of the nipple?
For cases diagnosed 2007 or later:
There are two primaries. Primary 1: The two tumors described on the pathology report from the lumpectomy are a single primary using rule M13. Primary 2: Disregard the foci of residual DCIS. Paget disease of the nipple is a separate primary using rule M12.
Primary 1: invasive mucinous adenocarcinoma and extensive ductal carcinoma in situ: Code the histology as 8480/3 [mucinous adenocarcinoma] using rule H27.
Primary 2: Paget disease of nipple: Code the histology as 8540/3 [Paget disease] using rule H14.
