20021094 EOD-Extension/EOD-Lymph Nodes--Testis: If the patient received chemo, should "bulky retroperitoneal adenopathy" be coded as involved lymph nodes in the EOD lymph node involvement field for a testicular primary treated with an orchiectomy that rendered a path diagnosis of "seminoma confined to the testicle"? See discussion. Per an orchiectomy path diagnosis a seminoma was confined to the testicle. The only other workup, other than a scrotal ultrasound, was a staging CT scan that revealed bulky retroperitoneal adenopathy in abdomen and pelvis, as well as mediastinal adenopathy. There was also a peripheral pulmonary nodule. No final clinical diagnosis or stage was provided in the chart. Following the orchiectomy the patient was treated with chemo. Should we also have coded distant site lung involvement?

For cases diagnosed 1998-2003, code the EOD-Lymph Nodes field to 9 [unknown] because "adenopathy" is not used to code lymph node involvement. The physician varied from the usual treatment for a localized testicular carcinoma, which is an orchiectomy. The physician proceeded immediately to chemotherapy as further treatment. It is not clear whether the decision to treat with chemo was based on the nodes and/or lung being involved.

Search the record for the physician's opinion regarding distant metastasis. Do not code distant involvement based on a peripheral pulmonary nodule seen on CT without further proof. If no further information is available, code the EOD-Extension field to 99.

20021174 Histology (Pre-2007)/Grade, Differentiation--All Sites: When the original pathology reports diagnosis indicates a grade and the review of slides (ROS) pathology report does not give a grade, can you code the histologic type from the ROS and the grade from the original pathology report? See discussion. For example, if the original diagnosis is "poorly differentiated carcinoma" and the ROS diagnosis is "squamous cell carcinoma," would the morphology code be 8070/33?

For tumors diagnosed prior to 2007:

Yes. Code the Histology and Grade, Differentiation fields to 8070/33 [poorly differentiated squamous cell carcinoma]. Code the higher grade when different grades are specified for the same specimen and code the more specific morphology (i.e., squamous cell carcinoma rather than carcinoma, NOS).

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.

20021045 Histology/Grade, Differentiation--Lymphoma: What code is used to represent the histology "high grade malignant lymphoma with features of so called blastic NK cell cutaneous lymphoma [hematodermic lymphoma]" found on punch biopsy?

For cases diagnosed prior to 1/1/2010:Code the Histology field to 9709/3 [cutaneous lymphoma, NOS]. Code the Grade, Differentiation field to 8 [NK cell].

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.

20021115 EOD-Lymph Nodes--Testis: In coding lymph node involvement for a testicular primary, should we use code 5 (Size not stated) when there is not a pathologic size of the lymph node provided? See discussion. Should Note 1 in the testis EOD be changed to "Metastases in lymph nodes are now measured by the size of the lymph node as stated in pathology report"? The SEER EOD-88, 3rd Edition, states that "when size of regional lymph nodes is required, code from the pathology report."

For cases diagnosed 1998-2003:

For testis cases only, "metastasis in lymph nodes" is measured by the size of the lymph node or the lymph node mass. It is acceptable to code the size of this metastasis from a CT scan or other imaging when a pathology specimen is not available for testicular primaries.

 2002
20020060 Terminology/EOD-Size of Primary Tumor--Lung: Can the term "opacity" be used to code the size of the primary lung tumor when it is given a size in an imaging study but the "opacity" is not referred to as being suspicious for cancer? See discussion. Example: How do you code tumor size for a lung primary in which the patient had a CT of the chest that describes a "4 cm opacity in the RUL of the lung." A biopsy of the RUL lung is positive for carcinoma? Would your answer be different if the opacity was described as being "suspicious for carcinoma"?

For cases diagnosed 1998-2003:

Code the EOD-Size of Primary Tumor field to 999 [Not stated] for the example given above. However, if the opacity was described as a "mass" or as "suspicious for cancer," the size could be coded to 040 [4 cm].

Grade/Histology (Pre-2007)--All Sites: What code is used to represent these fields for the histology "High grade dysplasia (adenocarcinoma in situ)" or "AIN III/High grade AIN"?

For tumors diagnosed prior to 2007:

Code the Histology field for the first example to 8140/2 [Adenocarcinoma, NOS, in situ] and for the second example to 8077/2 [AIN, grade III]. For both of the cases code the Grade, Differentiation field to 9 [Cell type not determined not stated or not applicable]. The 6th digit (grade code) of ICD-O-3 describes how much or how little a malignant tumor resembles the normal tissue from which it arose. In contrast, "grade" is used in the examples above to describe the degree of dysplasia, from mild dysplasia (low grade) to severe dysplasia (high grade). Do not record the degree of dysplasia in the 6th digit grade field.

For tumors diagnosed 2007 or later, refer to the MP/H rules for histology coding instructions. 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.

20021159 Histology (Pre-2007)--Breast: What code is used to represent the histology "mucinous carcinoma with Paget disease"?

For tumors diagnosed prior to 2007:

Code the Histology field to 8480/3 [mucinous carcinoma]. This answer assumes the patient presented with a single tumor. There is no combination code that includes these two entities. According to the rules for Coding Complex Morphologic Diagnoses, it would appear that the case should be coded to 8540 [Paget disease] because it is the higher code. However, this combination of histologies represents an exception to that rule. The prognosis for mucinous carcinoma is worse than the prognosis for Paget disease. As a result, it would be more appropriate to the histology to mucinous 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.

20020015 Histology (Pre-2001): For cases diagnosed before 1/1/01, what code is used to represent the histology "small cell neuroendocrine carcinoma"? For tumors diagnosed prior to 2001, code the Histology field to 8041/3 [small cell carcinoma] for "small cell neuroendocrine carcinoma". 2002
20020049 EOD-Extension--Breast: Should clinically mentioned "thickening" of the breast be ignored if the pathology report does not mention thickening or skin involvement? See discussion. For cases diagnosed 1998-2003: Can clinical "thickening" of the breast be coded to 20-28 extension code when there is no mention of the thickening or skin involvement in the pathology report? How do we code cases when pathology reports don't support the clinical finding of skin involvement. For cases diagnosed 1998-2003: Do not use code 20-28 when there is no preoperative treatment and the pathology report does not confirm skin invasion. The clinical diagnosis of skin involvement was not supported by the pathology report. 2002
20020002 Date Therapy Initiated: What date should be entered in Date Therapy Initiated when treatment follows a surgical procedure that is not coded under Surgery of Primary Site? See discussion. If a patient has a surgical procedure that is not coded in the Surgery of Primary Site field and then the patient undergoes additional first course of treatment, such as radiation therapy, how should the Date Therapy Initiated field be coded? In this example, code the Date Therapy Initiated field to the date of the first surgical procedure. If a SEER edit is triggered, please notify us. 2002
