Report Question ID Question Discussion Answer Year
20021089 Primary Site--Ovary/Peritoneum: When ovaries are not found on a resection or if the ovaries removed are negative for malignancy, but the clinician refers to the adenocarcinoma in the pelvis as being an "ovarian" primary, should the primary site be coded as ovary, pelvic peritoneum or unknown? See discussion.

Example 1: Patient has a history of a BSO without an indication that it was done for malignancy. Pt has a resection. No ovarian tissue found. No site is mentioned in the pathology report. The clinician refers to the diagnosis of adenocarcinoma in the pelvis as an "ovarian" primary.

Example 2: Resected ovaries are negative. No specific site of origin is mentioned in the path. Again, the clinician refers to the diagnosis of adenocarcinoma in the pelvis as an "ovarian" primary.

 Code the Primary Site for both examples to peritoneum [C48.2]. When the physician refers to a case as "ovarian" even though the ovaries are negative or when the histology is an ovarian histology, such as papillary serous ca, the primary site should be coded to the peritoneum. Code the Primary Site to where it appears the disease is arising. 2002

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.

20021021 Reportability--Hematopoietic, NOS: Should we add the missing terms listed in the Abstracting and Coding Guide for the Hematopoietic Diseases to ICD-O-3 because these absent synonyms would not be identified during hematology casefinding? See discussion. The Abstracting and Coding Guide for the Hematopoietic Diseases gives a preferred term for each code followed by a list of synonyms, not all of which are listed in the ICD-O-3. Two examples are: 1) 9962/3 [Essential Thrombocythemia] has 6 synonymous terms listed, but the last three of them are not in ICD-O-3. 2) 9930/3 [Myeloid Sarcoma] has the synonym "extramedullary myeloid tumor" which is not in ICD-O-3.

For cases diagnosed prior to 1/1/2010:Do not add these synonyms to ICD-O-3. The Abstracting and Coding Guide for the Hematopoietic Diseases lists synonyms for the preferred terms to assist in the classification of these other terms. In the absence of a specific code for the synonym, code to the preferred term. For casefinding, these terms would be grouped in a broader category of hematologic diseases under an ICD-9-CM or ICD-10 code and, therefore, will be identified during casefinding procedures using the disease index.

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.

20021034 Histology (Pre-2007): What code is used to represent the histology "adenocarcinoma in a tubulovillous adenoma with a mucinous component, the mucinous component is less than 50%"? See discussion. For mucinous only, the tumor must contain at least 50% mucinous to be coded to the specific histology.

For tumors diagnosed prior to 2007:

Code the Histology field to 8263/3 [adenocarcinoma in a tubulovillous adenoma]. Because the mucinous component involves less than 50% of the tumor, the histology is not coded to mucinous. For mucinous only, the tumor must be at least 50% mucinous, mucin producing, to be coded to the specific 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.

20021030 Grade, Differentiation--All Sites: Why was the decision made not to code all "3-component differentiation systems" the same way that Bloom-Richardson is coded? For example, SEER codes a low grade BR to 1 for the Differentiation field and a low grade for other grading systems to 2. See discussion. Our Pathologist Consultant agrees with SEER's guideline to code the Bloom-Richardson and B&R modifications of low, intermediate and high to 1, 2 and 3 respectively and thinks all 3-component systems should be coded that same way because it better represents the differentiation of the tumor. In his opinion, coding all other 3-component systems to a differentiation of 2, 3 and 4 respectively, is overstating the degree of differentiation. The rules for coding histology are approved and used by all of the major standard setters through agreements reached in the NAACCR Uniform Data Standards Committee. This issue is under review by our medical advisors and a special committee. Changes will be taken to the Uniform Data Standards Committee for review and approval. 2002
20021208 Reason for No Cancer-Directed Surgery: Could you explain why this field would be coded to 1 [Cancer-directed surgery was not recommended] or 2 [Contraindicated due to other conditions] for a case that presents with distant metastasis at diagnosis?

For cases diagnosed 1998-2002:

Code the Reason for No Cancer-Directed Surgery field to 1 [Cancer-directed surgery was not recommended] for patients who present with either a primary site or histology for which surgery is not a standard treatment. Also use code 1 for those patients who present with distant disease for a primary site that is typically treated surgically. Patients with distant metastasis typically do not have surgery performed as part of first course of treatment.

Code 2 [Contraindicated due to other conditions] is used when surgery would normally be recommended for the site (given the current stage of the tumor) but other medical conditions pose too much of a risk for the patient to undergo surgery.

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

20021172 EOD-Extension--Head & Neck: How much information is needed for a head and neck primary in order to code extension to localized versus unknown? What code is used to represent this field when the only information for a buccal cavity primary is a positive aspiration of the buccal mass?

For cases diagnosed 1998-2003:

Code the EOD-Extension to 99 [Unknown] for this case until more information is received. The available information does not describe the primary site and there is a complete lack of staging information.

Head and neck cancers spread early and often to nodes. Do not code the EOD-Extension to localized when the information is as limited as it is for this example.

20021209 EOD-Extension/EOD-Lymph Nodes--Rectosigmoid: How do you code these fields for a scan-based clinically staged T3 N1 rectosigmoid primary in a patient who received chemotherapy and radiation prior to a resection that demonstrated invasion only into the muscularis and no positive lymph nodes?

For cases diagnosed 1998-2003:

Use the best information available, in this case, the clinical staging, to code EOD. Code the EOD-Extension field to 40 [Invasion through muscularis propria or muscularis, NOS] and the EOD Lymph Node field to 3 [Regional lymph node(s) NOS] because the case had a clinical stage of T3 N1. EOD is coded using the most extensive clinical or pathologic stage.

 2002
20021048 EOD-Lymph Nodes: If chemotherapy or radiation is given prior to the excision of an involved lymph node, should the size of the metastasis within the lymph node be coded from the subsequent surgical pathology report? See discussion. For several sites, the size of the metastasis in an involved lymph node is integrated into the EOD-Lymph Node field. Should the size of the metastasis mentioned on the pathology report be ignored if the patient received radiation or chemotherapy prior to having the lymph node removed?

For cases diagnosed 1998-2003:

Record the size of a lymph node metastasis described in the pathology report for cases that had pre-surgical treatment. However, if both the pre-treatment and post-treatment size of the lymph node metastases are available, use the larger size when coding the EOD-Lymph Node field.
