Report Question ID Question Discussion Answer Year
20021051 EOD-Extension--Pancreas: Can you explain the difference between code 10 [confined to pancreas] and code 30 [Localized, NOS]. See discussion. For example, a CT scan mentions no extension beyond the head, body or tail of the pancreas and there is no surgical resection. Should we code extension to 10 or 30?

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 10 [confined to pancreas] because a scan supported the finding of no extension beyond the pancreas.

If the abstractor reviewing the medical record has scans, op reports, and/or pathology reports stating that the tumor is confined to the pancreas, code extension to 10 [confined to pancreas].

However, if the medical record only provides a patient history from a physician stating that the patient had localized pancreas, code extension to 30 [localized, NOS]. The NOS codes are used only when there is not enough information to code the specific codes (in this case, 10 or 20).

EOD-Extension--Pancreas: Should these terms be ignored when coding extension to 10 or 30, or do they indicate involvement for non-surgically treated pancreas primaries?

1) Stricture of the common bile duct

2) Common bile duct is narrowed

3) Common bile duct is obstructed

4) Common bile duct dilation

5) Malignant stricture of the common bile duct

6) Ampullary or common bile duct stricture with a negative biopsy or brush.

For cases diagnosed 1998-2003:

Ignore these terms when coding extension to 10 or 30. These terms do not verify involvement by pancreatic cancer of the organs mentioned. Other non-malignant circumstances could cause these conditions.

20021053 EOD-Extension--Pancreas: How would you code extension for the following non-surgically treated pancreas primaries? None of these cases has TNM staging to assist with classifying the extent of disease. See discussion.

1) CT scan: Cystic lesion in body of pancreas. Discharge dx: pancreas ca.

2) Discharge dx: CBD obstruction due to probable early ca in head of pancreas.

3) CT scan: mass involves the head and body of the pancreas. No evidence of abdominal mets. Discharge dx: Locally advanced pancreatic ca.

4) H&P: Pt with splenomegaly probably secondary to splenic vein thrombosis and a large ca of the tail of pancreas. Imp: Advanced pancreatic ca of the tail of pancreas. Would you code extension to splenic vein [56]?

5) H&P: Pancreatic ca with extension or mets into porta hepatis. (Would you assume direct extension or mets?)

6) CT scan: Pancreas ca. Significant peritoneal implants. (Would you assume the implants to be related to the pancreas primary and code as involvement?)

For cases diagnosed 1998-2003:

The information provided for these pancreatic primary examples is very limited. Additional information should be sought. If not available, code the EOD-Extension field to:

1) 10

2) 10

3) 10

4) 99

5) Assuming primary in head, body or tail of pancreas, 76

6) 85

20021054 Histology (Pre-2007)--Breast: What code is used to represent the histology "invasive ductal carcinoma, mucinous type and invasive lobular carcinoma"?

For tumors diagnosed prior to 2007:

Code the Histology field to 8522/3 [infiltrating duct and lobular carcinoma] per rule 1 of the Coding Complex Morphologic Diagnoses, because the tumor is both lobular and ductal.

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.

 2002
20021055 EOD-Extension--Liver: Can we use CT scan descriptions such as "portal vein thrombosis" or "extensive infiltration of the liver" or "diffuse infiltration of the liver" to code extension for liver primaries? See discussion.

1. Would you code portal vein involvement for a CT scan description of "portal vein thrombosis"?

2. Would you code more than one lobe of the liver as involved for CT scan descriptions of "extensive infiltration of the liver" or "diffuse infiltration of the liver"?

For cases diagnosed 1998-2003:

1. No. Thrombosis can be caused by non-cancerous conditions.

2. Yes. Code the EOD-Extension field to 65 [Multiple (satellite) nodules in more than one lobe of the liver] when "extensive infiltration" or "diffuse infiltration" is stated.

Histology (Pre-2007)/Terminology: Are "pattern", "architecture", and "architectural pattern" terms that indicate a majority of tumor?

For tumors diagnosed 2004 to 2006:

The terminology "Architectural pattern: ____________," when used in the final pathology diagnosis, indicates a subtype that can be coded. This type of format in a pathology report is based on a College of American Pathologists (CAP) protocol. Disregard "pattern" and "architecture" when not used in accordance with the CAP protocol. See www.cap.org for cancer protocols.

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.

Multiple Primaries (Pre-2007)--Breast: When simultaneously diagnosed breast tumors of the same histology in the same breast are stated by the pathologist and/or clinician to be more than one primary, should these be reported as multiple primaries? See discussion.

For example, based on special pathology studies that showed a difference in appearance between tumors, a pathologist may state that two ductal, NOS tumors diagnosed at the same time in the same breast represent two primaries.

For tumors diagnosed prior to 2007:

Code as a single primary. Follow the guidelines in the SEER Program Code Manual for determining multiple primaries. Simultaneous multiple lesions of the same histologic type in the same site (same breast) are a single primary for SEER, even though the pathologist may perform special studies and state that the patient has more than one primary.

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.

20021059 Surgery of Primary Site--Soft Tissue: What code is used to represent this field when an excisional biopsy of a soft tissue sarcoma is followed two weeks later with a wide excision (re-excision)? For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 26 [partial resection]. According to the CoC, "Excision" in the surgery codes refers to the lesion and "partial resection" refers to the organ. The biopsy is a local excision (code 25). The wide resection is code 26, presuming that more than just the remaining lesion was removed. 2002
20021060 EOD-Size of Primary Tumor: The EOD Manual instructs us not to code the size of a cyst. Can we code the size of tumor lesions described as being multicystic, multiloculated, or as a complex mass with cystic areas? See discussion.

Example 1: Large multicystic ovarian mass lesion measuring 10 cm. Sections through the specimen show a multicystic and solid mass with abundant fluid exuding from the cut surfaces (Size of the solid portions is not stated).

Example 2: A brain MRI: 9-cm. complex mass with cystic areas.

For cases diagnosed 1998-2003:

Yes, if the cystic mass is pathologically confirmed to be malignant, code the EOD-Size of Primary Tumor field based on the size of the mass in the absence of a more precise tumor size description. For the examples in the discussion section, code the EOD-Size of Primary Tumor field to: 1) 100 [10 cm]. 2) 090 [9 cm].

As a point of interest, the size of tumor for ovarian and brain primaries is not used in either analysis or as a prognostic indicator for survival. Therefore, spending time separating the cystic and solid portions of the tumor is unnecessary.

20021061 Multiple Primaries/Histology--Mycosis Fungoides/Cutaneous T cell Lymphoma: Physicians often use the terms cutaneous T cell lymphoma (CTCL) and mycosis fungoides interchangeably and yet the SEER Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates that these 2 diagnoses represent separate primaries. Do these cases represent one primary? If so, what histologic type should they be coded to?

For cases diagnosed prior to 1/1/2010:The patient does not have two different malignancies. Code the Histology field to 9700/3 [mycosis fungoides], the specific type of cutaneous T cell lymphoma. Mycosis fungoides is one of several types of cutaneous T cell lymphoma. Physicians often refer to mycosis fungoides by the "umbrella term" cutaneous T cell lymphoma.

The table indicates that the broad category of "T/NK-cell NHL" (which includes CTCL) and mycosis fungoides are presumably separate primaries because several entities are included in that broad category. In the specific case cited above, one entity (CTCL) within the broad category (T/NK-cell NHL) and mycosis fungoides are not separate primaries.

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.
