CS Extension: How is CS Ext coded for the following?
Rretroperitoneal primary
Cystic mucinous tumor with intraepithelial carcinoma
There is no CS Extension code for intraepithelial ca in the retroperitoneal scheme.
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 American College of Surgeons I & R system, assign code 10 [confined to site of origin] for intraepithelial carcinoma of the retroperitoneum.
CS Tumor Size: Is a 5.5 mm tumor coded as 005 or 006? See Discussion.
We interpret the CS Manual general instructions to indicate to ONLY round up to 001 when the tumor size is stated to be 0.1 to 0.9mm.
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 006. Because only whole numbers in mm can be collected, basic mathematical principles are used for rounding; 1-4 round down, 5-9 round up.
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.
Reportability: If a dermatopathologist refers to an atypical fibroxanthoma as a malignant process, but the ICD-O-3 indicates it is a borderline process, is this a reportable case? See Discussion.
"Final Diagnosis: Surface of ulcerated histologically malignant spindle cell neoplasm, consistent with atypical fibroxanthoma. Note: An exhaustive immunohistochemical work-up shows no melanocytic, epithelial or vascular differentiation. Atypical fibroxanthoma is a superficial form of a malignant fibrous histiocytoma."
The pathologist has the final say on behavior. In this case, the pathologist states that this tumor is malignant in the final diagnosis. Therefore, this case is reportable.
MP/H Rules--Brain and CNS: Are stigmata of neurofibromatosis in the brain reportable neurofibromatosis lesions? See Discussion.
Reference: SINQ 20051108; SINQ 20061018 Three year old patient with history of neurofibromatosis 1. 3/05 MRI of the brain showed right optic nerve glioma. It also showed heterogeneous high t2 signal in the middle cerebellar peduncles and near the genu of the internal capsules bilaterally are stigmata of neurofibromatosis type I. 3/08 MRI showed new mass suspicious for glioma in the hypothalamus. Clinical diagnosis is benign glioma secondary to diagnosis of neurofibromatosis. How many primaries are to be accessioned for this patient? Should the matrix principle be invoked for the second glioma? Should the behavior code for the glioma be 0?
For cases diagnosed 2007 through 2017
Accession NF (9540/1) when there is CNS tumor -- a glioma or some other intracranial/intraspinal tumor. Stigmata of NF are reportable when the stigmata themselves are reportable tumors. For example, glioma, or another intracranial/intraspinal tumor. Do not report sitgmata that are only termed "stigmata seen on MRI," for example, without other reportable terminology.
Do NOT accession NF (9540/1) when there is only peripheral nerve/nervous system involvement.
Accession the neurofibromatosis itself only once per patient. Accession any initial neoplasm in the CNS separately. Abstract and code any subsequent CNS neoplasms according to the multiple primary brain rules.
Accession three primaries for the case described above.
Neurofibromatosis (C729 9540/1)
Optic nerve glioma (C723 9421/3)--> see below.
Hypothalamus glioma (C710 9380/0)
--> Optic nerve gliomas associated with NF are pilocytic astrocytomas. Code pilocytic astrocytoma as 9421/3 in North America.
For cases diagnosed 2018 or later
See the 2018 Solid Tumor Rules for Non-Malignant CNS tumors.
Ambiguous terminology: Is the phrase "malignancy is highly considered" reportable given that the phrase "considered to be malignant" is reportable per SINQ 20061094?
"Malignancy is highly considered" is not a reportable ambiguous term.
Diagnoses qualified by the phrase "considered to be malignant" are reportable because this phrase is interpreted as "This diagnosis is malignant."
Scope Regional LN Surgery--Melanoma: How is this field coded when there is no primary skin lesion and the only disease present is one axillary lymph node that reveals melanoma? See Discussion.
According to SINQ 20061045, the CS Lymph Node field is coded to 80.
Code scope of regional LN surgery 4 [1 to 3 regional lymph nodes removed] for this case. One lymph node was removed. For this case, the axillary lymph node is coded as regional for the CS Lymph Node field. Therefore, include this lymph node is also coded in the Scope of Regional LN Surgery field.
Multiplicity Counter--Ill-defined sites: How is this field coded for Ill-Defined sites (C760-C768)?
Code the number of tumors present if known. If the number of tumors present is not known, code 99 [unknown number of tumors, unknown if multiple tumors].
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.
Multiple primaries--Lymphoma: Is mediastinal large B-cell lymphoma followed by classical Hodgkin lymphoma reportable as one or two primaries? See Discussion.
Diagnosed 06/06/2006 with mediastinal large B-cell lymphoma, 9679/36. On 05/10/2007, another mediastinal lymph node biopsy done and the diagnosis was recurrent malignant lymphoma, classical Hodgkin's. A Hematopatholgy Consultant states, "it appears likely that the preceding mediastinal diffuse large B-cell lymphoma and the current classical Hodgkin's lymphoma are clonally related and represent different manifestations of the same entity. One might also place this in the spectrum of 'mediastinal gray zone lymphoma' described by Dr. Jaffee and colleagues."
For cases diagnosed prior to 1/1/2010:Report this case as two primaries. Report non-Hodgkin lymphoma followed by Hodgkin lymphoma as separate primaries.
According to the Table of Single and Subsequent Primaries for Hematologic Malignancies, mediastinal large B-cell lymphoma and Hodgkin disease are "D" - Different disease processes.
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.
