Multiple Primaries/Histology--Hematopoietic, NOS/Lymphoma: How many primaries are represented and what are the histologies for "B-cell lymphoma with immunophenotypic findings consistent with hairy cell leukemia" found on a bone marrow biopsy? See Description.
Pathologist completed AJCC lymphoma staging form indicating this case should be abstracted as a lymphoma.
For cases diagnosed prior to 1/1/2010:Abstract as one primary, 9591/3 [B-cell lymphoma, NOS]. The bone marrow diagnosis indicates that the main/definite diagnosis is B-cell lymphoma, with a lesser indication of hairy cell leukemia. Both of these are mature B-cell neoplasms according to the WHO histological classification.
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.
Histology (Pre-2007)--Kidney, renal pelvis: What codes are used to represent the histologies of 1) "renal papillary (chromophil) carcinoma" and 2) "chromophil renal cell carcinoma?"
For tumors diagnosed prior to 2007:
Code "chromophil" to 8260 [papillary renal cell]. According to our pathologist consultant, in the case of chromophil, most authors regard this as more or less synonymous with papillary renal cell [8260]. "More or less" because papillary is an old term descriptive of the microscopic structure, while chromophil is newer and based on the cytology; because most of the latter are papillary the current usage assumes them to be equivalent.
1) The diagnosis "renal papillary (chromophil) carcinoma" tells us that the pathologist who wrote it was seeing both pattern and cytologic features, and is regarding papillary equivalent to chromophil; thus, code to 8260.
2) Code "chromophil renal cell carcinoma" to 8260.
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.
Surgery of Primary Site--Lung: Is a core-out of the main bronchus coded in this field? See Description.
Patient with right lung cancer was not a surgical candidate because of extent of disease. Prior to receiving radiation, patient underwent bronchoscopy, which revealed obstruction from right main bronchial tumor. Core-out of the tumor was undertaken, and a specimen was sent for path evaluation. The physician stated that this was a palliative procedure to relieve obstruction.
Do not code bronchoscopy to clear the airway as surgery of primary site. When combined with laser therapy, cryosurgery, or other tumor destruction, or when combined with excision of tumor, code as surgery of primary site.
For cases diagnosed 1998-2003: Code surgery of primary site for the case described above to 23 [Excision, NOS]. Tissue was excised and sent to pathology.
Primary site--Melanoma: Should melanoma of the nipple be coded to C50.0 [Nipple] or C44.5 [Skin of the trunk]?
Code to C44.5 [skin of trunk]. External melanoma is an epidermal malignancy, beginning in melanocytes in the basal layer of the epidermis. C50.0 excludes skin of breast.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Kidney: How many primaries, with what histology(ies) should be coded when nephrectomy pathology specimen shows separate tumors of "renal cell carcinoma [clear cell type]" and "renal cell carcinoma [granular cell type]"?
For tumors diagnosed prior to 2007:
Abstract two primaries. This is an example of two tumors with different histologic types in the same site. The right kidney has two separate tumors.
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.
Primary Site--Ovary/Peritoneum: Should this field be coded to ovary or peritoneum when the bulk of the tumor is in the peritoneum and there is only surface involvement of the ovary?
If it is not clear where the tumor originated, use the following criteria to distinguish ovarian primaries from peritoneal primaries.
The primary site is probably ovarian, unless:
--Ovaries have been previously removed
--Ovaries are not involved (negative)
--Ovaries have no area of involvement greater than 5mm.
Descriptions such as "bulky mass," "omental caking" probably indicate an ovarian primary.
Descriptions such as "seeding," "studding," "salting" probably indicate a peritoneal primary.
Primary Site/Histology (Pre-2007)--Mediastinum: How do we code these fields for a case described as a "neuroendocrine carcinoma" of the "anterior mediastinum" without failing the SEER "impossible" site/histology combination edit? See Discussion.
Two different facilities state that the patient has "neuroendocrine carcinoma of the anterior mediastinum." This coded combination failed SEER edit (SEERIF38). We can not correct it because that edit flag does not appear on our system. Both facilities indicate that the mediastinum is the primary. In addition, there is text to support both the histology and primary site codes.
For tumors diagnosed prior to 2007:
The combination of C381 [anterior mediastinum] and 8246 [neuroendocrine carcinoma] will be removed from the list of "impossible" site/histology combinations. There are rare cases of neuroendocrine carcinoma of the anterior mediastinum. As illustrated in the discussion, verify that the primary site is anterior mediastinum, the histology is neuroendocrine ca, and document those findings in the text.
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.
CS Tumor Size--Breast: When the diagnosis is inflammatory carcinoma of the breast, must the CS tumor size always be 998? See Discussion.
I have no specific example of a situation; I am writing an edit check and wondering if there would be any exceptions to this rule.
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. For inflammatory carcinoma, code the size of the tumor in CS tumor size. Use code 998 [diffuse] when the tumor is stated to be "diffuse."
Page 27 in Part I of the CS manual will be corrected to define code 998 for breast as only "diffuse." The errata should be distributed in July 2004.
EOD-Extension--Retroperitoneum: Does the presence of "necrotic masses, NOS" in the blood, which are not pathologically evaluated, affect the coding of this field? See Description.
Encapsulated malignant tumor within the retroperitoneum was removed. Surgical report: "In the abdomen, blood had necrotic masses floating freely and encapsulated a 3-4" mass." No pathologic assessment of the necrotic masses is available.
For cases diagnosed 1998-2003: Necrotic masses do not affect the EOD-extension code.
