Report Question ID Question Discussion Answer Year
20031026 EOD-Extension--Head & Neck: If there is no mention of vocal cord mobility, do we code indicating normal vocal cord mobility or do we code EOD-Extension to a "localized, NOS?" See discussion. How do we code EOD-extension for the following tumor of the supraglottic larynx? Limited stage small cell cancer of epiglottis per discharge signout. Physical exam revealed swelling of anterior aspect of epiglottis and narrowing of epiglottis. Neck without palpable masses. Laryngoscopy with biopsy and esophagoscopy showed extensive tumor involving entire laryngeal surface of epiglottis, extending onto aryepiglottic fold, onto false vocal cords and onto left true vocal cord. Ventricle on left side was obliterated with tumor. Right true vocal cord free of tumor. There is no information regarding vocal cord mobility. Biopsy of the left true vocal cord was negative. Should EOD-extension be coded to 20 [Tumor involves more than one subsite of supraglottis without fixation or NOS] or 50 [Localized NOS]? For cases diagnosed 1998-2003, if vocal cord mobility is not mentioned, code as normal mobility. Code EOD-extension for the example case as 20 [Tumor involves more than one subsite of supraglottis without fixation or NOS]. 2003
20031210 Other Cancer-Directed Therapy--Hematopoietic, NOS: Is there a hierarchy for selecting which code to use when a patient receives more than one type of "other treatment"? See Description. Patient was diagnosed with Myelodysplastic Syndrome, probably refractory cytopenia with multilineage dysplasia. Good candidate for investigational studies for transfusion-dependent patients. Patient was enrolled in a high dose vitamin D study. Patient also received transfusions.

SEER has not established a hierarchy of the codes listed under Other Treatment. If the patient receives more than one type of other treatment as the first course of treatment, assign the code that provides the most information about how the patient was treated and use the remarks fields to explain.

Code Other Treatment for the case example above as 2 [Other experimental therapy]. Use the remarks fields to describe the transfusions and vitamin D therapy.

20031035 Reportability/Histology--Hematopoietic, NOS: Does the presence of sideroblasts on a bone marrow biopsy confirm a diagnosis of refractory anemia with sideroblasts?

Final path diagnosis of bone marrow biopsy:

I. Hypercellular marrow for age with trilinear hyperplasia.

II. Decreased iron stores with decreased sideroblasts.

Comment: Although the overall picture is not diagnostic of a specific entity, it is most consistent with an early stage myelodysplastic syndrome which would best be considered refractory anemia at this point.

In this case the percentage of sideroblasts is not stated. Would the path diagnosis of "decreased sideroblasts" along with the path comment of "refractory anemia" indicate that this case should be coded to 9982/3 [Refractory anemia with sideroblasts]?

For cases diagnosed prior to 1/1/2010:

For the hematologic diseases, do not accession the case unless there is a definite positive diagnosis. A positive diagnosis, such as "Refractory anemia" must be stated in order to code that diagnosis. Other words associated with the positive diagnosis, such as "sideroblasts" are NOT to be used alone to assume a diagnosis.

Decreased sideroblasts does not make a diagnosis of Refractory anemia with sideroblasts. The sideroblasts for 9982/3 [Refractory anemia with sideroblasts] are characteristic in rings, and are INCREASED to make the diagnosis.

Based on the information provided, this case is not reportable. The final path diagnosis is not a reportable disease. The comment further states that the overall picture is not diagnostic of a specific entity. Therefore, it should not be reported at this point.

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.

20031134 Surgery of Primary Site/Immunotherapy--Bladder: Is administration of BCG coded as both surgery and immunotherapy? Yes, code as both surgery and immunotherapy. The CoC included immunotherapy/BCG under surgery and also under immunotherapy by request of the clinical advisor for bladder, reflecting the mixed-modality nature of the treatments. [Answer from CoC I & R] 2003
20031043 EOD-Extension--Corpus Uteri: How is this field coded for a stage III A endometrial primary with positive pelvic washings, involvement of the omental serosa, and negative lymph nodes? For cases diagnosed 1998-2003: Code EOD-extension as 85 [Metastasis]. According to our TNM consultant, Omental metastasis is M1, Stage IVB [EOD 85]. 2003
20031132 EOD-Lymph Nodes--Breast: Are micrometastases in the lymph nodes, found only on immunohistochemical staining, coded as positive lymph nodes?

For cases diagnosed 1998-2003: Do not code as positive lymph nodes that have micrometastases diagnosed ONLY on immunohistochemistry. By traditional diagnostic methods, these are still negative lymph nodes.

Summary Stage and EOD ignore the IHC positive micrometastases for cases diagnosed through 2003. The collaborative staging system that begins with 2004 cases and is based on the sixth edition of TNM addresses this issue.

20031089 Primary Site/Histology (Pre-2007)--Bone: How are these fields coded for a squamous cell carcinoma in bone? See Description. The consult path report says "I believe that there is definitely high grade malignant tumor in this amputation specimen, and that this tumor represents an invasive squamous cell carcinoma, which is extending into the bone and permeating in between the bone trabeculae. ... The fact that squamous cell carcinoma can arise from the sinuses of chronic osteomyelitis is well recognized."

For tumors diagnosed prior to 2007:

Based on the information provided, code the primary site as C40._ or C41._ [bone] because the tumor originated in the sinuses of chronic osteomyelitis. Code to the site in which the tumor arises. Override the SEER site/histology edits to allow this rare combination of bone and squamous cell carcinoma.

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.

20031082 EOD-Size of Primary Tumor: Pathologist states that the size of the tumor is difficult to measure but is greater than 3cm but less than 5cm. How would we code the tumor size?

For cases diagnosed 1998-2003:

Code the largest dimension mentioned, since that is the standard rule for coding tumor size. Keep in mind that tumor size is not used in analysis for certain sites such as stomach, colon & rectum, ovary, prostate, and urinary bladder. Tumor size is important for analysis for certain sites such as lung, bone, breast, and kidney.

20031202 Surgery of Primary Site--Head & Neck: How is this field coded for a surgery titled "Parotidectomy with facial nerve dissection"? See Description. If the operative report is not titled "total parotidectomy," can we assume that less than total parotidectomy was done? Can we assume that "facial nerve dissection" and "facial nerve monitoring" are other ways of stating "facial nerve spared"?

Use the best information available to determine whether or not all of the parotid has been removed. It is important to read the entire operative report and review the content of the pathology report. The Op report will usually include wording about how much was removed, and this can be confirmed by the path report. Do not make assumptions about the extent of the surgery based solely on the title used on the operative report.

For cases diagnosed 1998-2003: Code 30 [less than total parotidectomy] can be used when the parotid is not totally removed, but the exact type of partial parotidectomy cannot be determined. "Facial nerve monitoring" and "Facial nerve dissection" are synonymous with "facial nerve sparing."

20031053 Reportability/History (Pre-2007)/Behavior Code--Ovary: Should the matrix principal in Rule F be applied to code a 2002 right ovary case to 8462/3 [Papillary serous borderline ovarian tumor] when peritoneal washings reveal the same histology?

For tumors diagnosed prior to 2007:

Do not apply the matrix principle in this case. This ovarian tumor is not reportable (behavior /1 per ICD-O-3). The peritoneal washings reveal the same histology (/1), rather than malignant cells. Based on the information provided, there is no evidence to support changing the behavior code.

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.
