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.
EOD-Size of Primary Tumor--Cervix: When both a depth and diameter of the tumor are provided and the description of the diameter is provided in a range, how do you code the size of the primary tumor? See discussion.
Path states "microscopic focus of endocervical glands considered invasive adenoca...maximum depth of that focus measures approximately 2 mm. Maximum diameter of that focus measures 3-4 mm."
What size would be coded for this case: 999, 002, 003, or 004?
Code the EOD-Size of Primary Tumor field to 004 [4 mm]. Code the diameter dimension in the EOD-Size of Primary Tumor field and the depth dimension iin the EOD-Extension field. Code the largest number associated if a range is provided for the diameter of the invasive tumor.
If the size of the diameter had not been mentioned, the EOD-Size of Primary Tumor field would have been coded to 001 [microscopic focus or foci only], which ignores the size associated with the depth dimension of the tumor.
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.
EOD-Extension--Urinary Tract: Can the rules used to code bladder extension involving the term "no involvement of muscularis/and no mention of subepithelium/submuscosa" be used to code extension for other urinary tract primaries, such as ureter?
For cases diagnosed 1998-2003:
No. The inferred descriptions of noninvasion apply to bladder cases only.
Primary Site--Head & Neck: What site code is used to represent the following head and neck primary where there is not a clear statement of primary site? See discussion.
6/29/02: PE: 2-3 cm mass in the posterior pharynx that seems to arise from the right side of back of tongue.
6/29/02 CT soft tissue of neck: 3 cm right sided oropharyngeal mass, possibly arising from right tongue mass. There is near occlusion of airway at this level.
7/3/02 Excision of oropharyngeal tumor: Palpated mass could clearly be felt coming off the right lateral tongue in approximately the mid portion of the tongue near the tonsillar base.
Code the Primary Site field to C02.9 [tongue, NOS], based on the information provided.
Date of Diagnosis/Histology (Pre-2007)--Breast: When there is a delay between the clinical diagnosis of a malignancy and the surgical resection of the primary site, can the resection be used to code the date of diagnosis, extension, size of the primary tumor, and histology? See discussion.
For example, mammogram March 28th states "certainly represents malignancy." Nothing else done until November 1st when pt presents w/skin retraction on PE and bone mets. A mastectomy November 6th shows "ductal ca w/dermal lymphatic invasion and tumor measuring 3.5 cm."
How is the date of diagnosis, extension, tumor size & histology coded for this case?
For tumors diagnosed prior to 2007:
Code the Date of Diagnosis to March. Code the Histology field to 8500/3 [Infiltrating duct carcinoma]. Histology can be upgraded from a clinical histology to a pathological histology anytime.
For cases diagnosed 1998-2003, in coding extension, you need to assess whether there has been progression of disease or not. If progression of disease is verified, do not code extension using the surgical information from November. Code the extension and tumor size based on the mammogram and physical examination at the time of the mammogram, if available.
If no progression of disease is verified, use surgical information to code extension and tumor size.
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.
EOD-Extension--Lymphoma: What code is used to represent this field for an extranodal lymphoma that has more than one tumor in the primary site OR has intraluminal extension from the primary site to an adjacent organ? See discussion.
1. Small lymphocytic lymphoma with 2 tumors in the stomach.
2. Lymphoma involving the cecum and ileum.
3. Lymphoma of the fundus of stomach with extension into the esophagus.
For cases diagnosed 1998-2003:
Using the EOD scheme for lymphoma, code the Extension field to 11 [Localized involvement of a single extralymphatic organ or site; Stage IE] for all 3 of these cases.
For the stomach lymphoma: There are 2 areas of lymphoma, but it is still confined to one site.
For the other 2 lymphomas: Intraluminal (mucosal) spread of the lymphoma never equals extension. The same phrase that was added to code 21, "Direct extension to adjacent organs or tissues", will be added to code 11 in the Collaborative Stage System. Neither "mucosal spread to a contiguous organ" or "direct extension into a nearby organ" affect staging. Both are still coded to 11 as long as there are no other sites of lymphoma involvement.
EOD code 80 is poorly written. It does not mean diffuse invovement or multiple tumors in a single organ but rather "diffuse disease in two or more organs."
Grade, Differentiation--All Sites: What code is used to represent this field when a pathology report describes a tumor as a low grade neoplasm consistent with a specific histologic type (e.g., Low grade neoplasm consistent with carcinoid)?
Code the Grade, Differentiation field to 2 [Low grade].
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.
