Histology--Heme & Lymphoid Neoplasms: What is the correct histology code for a diagnosis of mature B cell leukemia/lymphoma diagnosed only on a peripheral blood smear?
Code the histology to 9591/3 [B-cell lymphoma, NOS].
After searching the Heme DB for the term , no B-cell leukemia/lymphoma NOS code is found. However, the diagnosis of B-cell lymphoblastic leukemia/lymphoma is found. This case scenario does not specify that this is a lymphoblastic leukemia/lymphoma; therefore, the histology code 9811/3 [B-cell lymphoblastic leukemia/lymphoma, NOS] cannot be applied.
A subsequent search of the Heme DB for the term returns "Non-Hodgkin lymphoma, NOS" [9591/3]. Under the Alternative Names section of the Heme DB, B-cell lymphoma, NOS, is a synonym for Non-Hodgkin lymphoma, NOS. Therefore, the B-cell lymphoma NOS code [9591/3] is the most appropriate histology code to use for this case.
This will be added to the next revision of the Heme DB and Manual.

Primary site--Heme & Lymphoid Neoplasms: Is a peripheral blood equivalent to bone marrow biopsy for the purposes of Rule PH26 and code the primary site to C421 [Bone marrow] for a marginal zone lymphoma found in peripheral blood when there was no additional workup (e.g., scans, etc.) for this case?
Code the primary site to C421 [bone marrow]. Our hematopoietic specialty physicians state that involvement of peripheral blood is equivalent to bone marrow involvement because the marrow produces blood. In the absence of any other involvement, per Module 7 (Coding primary sites for lymphomas) Rule PH26, it states to code the primary site to bone marrow when the only involvement is bone marrow.

Unless the disease is specified as primary, idiopathic, essential, or the physician states there is a myeloproliferative neoplasm, the term thrombocytosis, NOS is not reportable. Thrombocytosis, NOS, is the presence of high platelet counts in the blood. Thrombocytosis can be associated with chronic infections and other diseases as well as with myeloproliferative disease. Thrombocytosis, NOS is listed in Appendix F as a Non-Reportable Term.

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.

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.
Surgery of Primary Site/Date Therapy Initiated--Cervix: Should "negative endocervical curettings" be coded as surgical treatment for carcinoma in situ of the cervix primaries and should the date of the procedure ever be used in coding the Date Therapy Initiated field?
For cases diagnosed 1/1/2003 and later: Code Surgery of Primary Site to 25 [D&C endocervical curettage (for in situ only)]. If this is the first treatment given, the Date Therapy Initiated is coded to the date of the curettage.
MP/H Rules--Colon: What histology would you assign to a single tumor with the histology 'well differentiated mucinous cystadenocarcinoma in a villous adenoma confined to the appendix'? Does rule H4 apply to this diagnosis or should we continue on in the rules to H14 and code the higher histology?
For cases diagnosed 2007 or later, use rule H4.
Stop at the first rule that applies to the case. Rule H4 is the first rule that applies.
The polyp rule, H4, comes before many of the other colon rules because it is important to know that the malignancy originated in a polyp.
EOD-Extension--Kidney: If a "tumor thrombus" in a renal vein is discontinuous from the primary tumor in the kidney, is it still coded to 60 [Tumor thrombus in a renal vein, NOS], rather than 85 [Metastasis]?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 60 [Tumor thrombus in a renal vein, NOS]. A thrombus can be a bolus of tumor cells within a large vein that may or may not still be connected/contiguous with the primary tumor. However, both a discontinuous and contiguous thrombus are coded to 60.
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).
