CS Extension--Lung: If only a "single" cytology is performed on pericardial fluid and it is negative, can Note 6 B, which states that pleural effusion [code 72] is coded as malignant unless there are "multiple" negative cytologies, be used to infer that the pericardial fluid should also be coded as involvement?
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.
No, do not apply the instructions for pleural effusion to pericardial effusion. Do not code a pericardial effusion proven negative by cytology in CS Extension.
Reportability--Melanoma: Is the following reportable? See Discussion.
PATH: Skin, Lt back exc bx: compound nevus with severe cytoarchitectural atypia and regression. Comment: due to overlap of morphology between MM and nevi with severe atypia, and since there's evidence of regression, consideration for re-excision may be considered if clinically indicated.
The final diagnosis, compound nevus with severe atypia, is not reportable. This diagnosis is not listed in ICD-O-3.
CS Extension--Lung: Can extension be coded to 10 (Tumor confined to one lung) when either an autopsy or a CT scan describes the tumor as a mass of a specified size located in one lobe of the lung without any description of extension and no available TNM provided? See Discussion.
Example 1: Lung primary within the right lower lobe described clinically as greater than 3 cm on scan but was found to be 3 cm at autopsy.
Example 2: CT scan February shows 2 cm mass in RUL.
In both cases, the only tumor description was the size of tumor without any information regarding extension.
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.
Yes, assign code 10 [Tumor confined to one lung] for a mass in one lobe when none of the descriptions in codes 11 to 80 are documented.
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.
CS Extension--Head & Neck: If a 2 cm left tonsil primary extends to the lateral aspect of the soft palate, should extension be coded to 40 [Soft palate, inferior surface including uvula or soft palate NOS] or 42 [Soft palate, superior (nasopharyngeal) surface] for a tonsil primary?
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.
Extension code 40 is for extension from the tonsil to the back (lower) part of the soft palate, or soft palate, NOS. Code 42 is for extension to the front (higher, nasopharyngeal surface) part of the soft palate.
Inferior soft palate is the back (lower) part of the soft palate (C051). Superior soft palate is the front, (nasopharyngeal surface) of the soft palate (C113).
Reportability--Hematopoietic, NOS: Is a "Myelodysplasia, refractory macrocytic anemia with multilineage dysplasia" reportable?
For cases diagnosed prior to 1/1/2010:Yes, myelodysplasia, refractory macrocytic anemia with multilineage dysplasia is reportable. This is a type of refractory anemia. Refractory anemia is reportable.
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--Melanoma: Is an excisional biopsy of the skin with a diagnosis on the pathology report of "Tumoral melanosis" reportable by itself or must there be a pathologist note, such as "Note: Unless proven otherwise, tumoral melanosis should be considered as a regressed melanoma", in order for it to be reportable? See Discussion.
Skin, left upper back, exc Bx: Tumoral melanosis. Note: Unless proven otherwise, tumoral melanosis should be considered as a regressed melanoma.
If reportable, do we report a diagnosis of tumoral melanosis without a similar note?
Tumoral melanosis (TM) alone is not reportable. It is not listed in ICD-O-3. TM can be associated with a regressed melanoma, but it can also occur with other cutaneous tumors. The case is reportable if there is a diagnosis of melanoma.
CS Site Specific Factor 6--Breast: If the tumor size for the breast is unknown, and it is unknown whether the tumor is mixed in situ and invasive or "pure", how is SSF6 to be coded? See Discussion.
The definition for SSF6 for breast changed from "Unknown if invasive and in situ components present, unknown if tumor size represents mixed tumor or a pure tumor" to an added clarification of "Clinical tumor size coded." Since the clinical tumor size is NOT coded, this does not fit.
The definition for 060 is "Invasive and in situ components present, unknown size of tumor (CS Tumor Size coded 999). Since it is unknown if the tumor is mixed, this definition does not fit either.
It seems that the revised (April 2005) definition for 888 has left a situation that cannot be 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.SSF 6 should be coded 888 in this case. SEER will make the CS task force aware of this situation.
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.
Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?
Assign code 1 [Positive histology]. For leukemia only, assign code 1 for positive hematologic findings including peripheral blood smears, CBCs and WBCs.
Cytogenetics studies would have been done on blood. Therefore, histology provided diagnostic confirmation as it would with smear, bone marrow, or other special study of blood cells.
