CS Site Specific Factor--Head & Neck: If a lymph node dissection of the neck reveals that 1/24 lymph nodes is positive and the positive 5.6 cm lymph node extends throughout levels II-IV, how are the SSF 3 (status of levels I-III lymph nodes) and SSF4 (status of levels IV-V lymph nodes) fields coded?
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.According to the CS Steering Committee, code 999 for SSF 3 and SSF 4. In this case, do not make assumptions about which level of lymph nodes were involved.
CS Lymph Nodes--Lung: Do modifying terms such as "borderline" affect whether lymph nodes are coded as involved when they are used in conjunction with the descriptors listed in Note 2 (i.e., mass, adenopathy or enlargement) for lung primaries? See Discussion.
Lung primary: CT states "borderline" enlarged hilar lymph nodes. Note 2 in the Lung schema under CS Lymph Nodes does not address qualifiers.
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 the hilar lymph nodes as involved in this case. "Borderline" enlarged hilar lymph nodes do not meet the clinical criteria for enlargement.
CS Tumor Size--Breast: Should this field be coded to 999 [Unknown] or 008 [0.8 cm tumor] when the tumor size is not provided on a stereomammotomy biopsy for an in situ malignancy and a subsequent excision demonstrates 0.8 cm tumor of residual in situ disease?
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 tumor size 008 [0.8cm]. A mammotomy specimen is very small, so for this case, the residual tumor size is quite accurate. Size is not a critical data element for in situ breast cancer.
Reportability: Is an AIN III that arises in perianal skin, skin tags or condyloma acuminatum reportable or must an AIN III arise in the anus or anal canal in order to be reportable?
AIN III arising in perianal skin [C445] is not reportable.
AIN III [8077/2] of the anus or anal canal is reportable.
CS Extension--Lymphoma: If bilateral tonsils are involved with lymphoma, is it one or two regions of involvement and how is extension coded?
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.For cases diagnosed 1-1-08 and later: Assign CS extension code 10 [involvement of a single lymph node region]. Bilateral tonsils are one organ/site.
See Note 1 under CS Extension. Tonsil is coded the same as a lymph node region.
Histology (Pre-2007)--Head & Neck: How is a "sinonasal undifferentiated carcinoma (SNUC)" coded?
For tumors diagnosed prior to 2007:
Code histology to 8020 [carcinoma, undifferentiated]. "Sinonasal" refers to anatomic location of primary site not histology.
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.
Date of Diagnosis/Histology--Hematopoietic, NOS: How are these fields coded if a 3/17/03 bone marrow biopsy diagnosis of "malignant proliferative disorder" is subsequently confirmed to be a "low grade lymphoma" per a bone marrow biopsy in early 2006? See Discussion.
3-17-03: Bone marrow biopsy from rt iliac crest: Hypercellular marrow (90%) with extensive involvement by lymphoproliferative disorder (see description). Micro: The bone marrow is diffusely (>90%) involved by a malignant lymphoproliferative disorder. This consists of small lymphocytes,histiocytes, and large atypical cells with prominent nucleoli.
12-22-05 Extensive bone marrow involvement by lymphoproliferative disorder, bone biopsy from femur.
1-27-06 Hem/Onc Physician Note:
following pt for a lymphoproliferative disorder. ...bone marrow biopsy 2003, suggestive of, but not truly diagnostic, a lymphoproliferative disorder. Therefore, I elected not to do anything, but just follow her.
3-23-06 Hem/Onc Note:
pt with a history of an apparently low-grade lymphoma involving the marrow, as well as, I believe, the liver and recently pathologically diagnosed as a T-cell-rich B-cell lymphoma. ...followed in the past by Dr. ___ and has never actually had any treatment for this lymphoma, although it is documented even three years ago by bone marrow biopsy.
For cases diagnosed prior to 1/1/2010:
Code the diagnosis date to 3/17/03. The histology code is 9970/3 [Malignant myeloproliferative disorder]. The bone marrow biopsy confirms a "Malignant" lymphoproliferative disorder. Apply ICD-O-3 rule F and assign /3 to histology code 9970.
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.
Reportability--Lymphoma: Is a lymphoma diagnosed on a bone marrow biopsy reportable if the cytogenetics evaluation performed does not confirm the malignancy? See Discussion.
Bone marrow Bx: Marginal zone lymphoma/leukemia. The morphology of the lymphoma/leukemia cells and the immunophenotypic characteristics identified by flow cytometry are consistent with marginal zone lymphoma/leukemia.
Addendum Report: Cytogenetic evaluation revealed a 46,XY male karyotype. This is the normal male chromosome karyotype. Based on the limits of this methodology, no evidence of hematologic malignancy was observed in this specimen.
For cases diagnosed prior to 1/1/2010:
Yes, this case is reportable. The cytogenetic evaluation cited in the addendum report does not disprove the bone marrow biopsy diagnosis.
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.
Multiple Primaries/Histology--Lymphoma: If an oral mucosa, right hard palate biopsy contains a composite lymphoma [low-grade follicular + chronic lymphocytic leukemia], how many tumors should be abstracted and how should the histology field(s) be coded?
For cases diagnosed prior to 1/1/2010:This is one primary. Assign code 9590 [Malignant lymphoma, NOS]. This is a composite lymphoma. Code to lymphoma when there is any solid tumor (in lymph nodes, tissue, etc.) Code to lymphoma, NOS since this is not purely follicular and there is no code for composite 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.
