EOD-Extension--Lung: Should the phrase "some pleural fluid in both posterior gutters" be interpreted as pleural effusion for lung primaries? See discussion.
CT scan: "3 cm mass left upper lobe of lung. Some pleural fluid in both posterior gutters. Large matted hilar lymph nodes, left. Some narrowing left upper bronchus by this adenopathy. Squamous cell ca lung with mets to left hilar lymph nodes, most likely possibility." Would you code extension to 72 [malignant pleural effusion; pleural effusion, NOS]?
For cases diagnosed 1998-2003:
Yes. Code the EOD-Extension field to 72 [malignant pleural effusion, pleural effusion, NOS]. Pleural effusion is mentioned as being present.
EOD-Size of Primary Tumor--Prostate: Should the size of tumor be recorded as 001 (focus) or the actual size when both are stated? See Discussion.
The pathology report from a TURP identifies a 3-mm focus of adenocarcinoma.
For cases diagnosed 1998-2003, code the EOD-Size of Primary Tumor field to 003 [3 mm]. The rule that says to code a focus or foci of tumor as 001 was developed for use when no tumor size is given.
Measured Thickness/EOD-Extension--Melanoma: If the Clark's level is not provided, can it be estimated using the depth of invasion provided in the pathology report and associating that number with the Clark's levels identified in the SEER Summary Staging Guide?
For cases diagnosed 1998-2003:
No. Do not use the SEER Summary Stage Guide or any other guide to derive an estimated Clark's level from the thickness identified in the pathology report. The two measurements need to come directly from the pathology report. Each is coded separately in EOD. Thickness is collected in a separate field so we can capture the actual measurement stated in the pathology report. This has made it possible for us to group depth of invasion for analysis purposes in any manner we might wish. In addition, we can always collapse this information to the Summary Stage or TNM using the AJCC rules. AJCC rules use both depth of invasion and thickness in determining pathologic staging, and, if there is an inconsistency between them, the rules say code to the higher T classification, that is, the least favorable finding.
Primary Site--Lymphoma: How should you code the primary site for a lymphoma that presents with involvement of an extranodal site and regional lymph nodes? See discussion.
1. Lymphoma involves the spleen and the splenic lymph nodes.
2. MALT Lymphoma involves the stomach and the gastric and iliac lymph nodes.
1. Code the Primary Site field to C42.2 [spleen].
2. Code the Primary Site field to C16._ [stomach].
When lymphoma presents in an extranodal site and in the regional lymph nodes for that extranodal site, code the Primary Site field to the extranodal site. The typical disease process is that lymphoma can spread from an extranodal organ to its regional lymph nodes. It cannot metastasize from the regional lymph node to the extranodal organ. The exception to this would be if the lymph nodes presented as one large mass that extended into the regional organ.
Diagnostic Confirmation--Testis: How do you code this field when a testicular mass is confirmed to be cancer on physical exam and testicular antigen, but the orchiectomy specimen was negative and yet the final signout diagnosis on the medical record was "testicular cancer"?
Code the Diagnostic Confirmation field to 5 [Positive laboratory test/marker study] because the disease was confirmed both clinically and by a positive marker. Code 8 [Clinical diagnosis only] is used when the diagnosis is based on information other than that coded in 5, 6, or 7 [positive lab test/marker study, visualization, and radiography or other imaging techniques]. Code 8 is rarely used.
Histology (Pre-2007)--Kidney: What code is used to represent the histology "renal cell carcinoma with granular cell morphology"? Kidney primary with diagnosis of renal cell CA with granular cell morphology. Do we code as granular cell carcinoma? Is the term "morphology" synonymous with "type"? See discussion.
Do we code this type of tumor as a granular cell carcinoma [8580/3]?
For tumors diagnosed prior to 2007:
Code the Histology field to 8320/3 [granular cell carcinoma]. Renal cell carcinoma is a non-specific term that has several specific cellular subtypes, one of which is granular cell [8320/3].
Note: Do not code to granular cell tumor [9580/3], which is not a histology related to renal cell 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.
Multiple Primaries (Pre-2007)--Skin: If a patient presents with two separate lesions on the left cheek (i.e., left lateral cheek and left upper cheek) that both are histologically confirmed to be superficial spreading melanoma on the same day, is this coded as one or two primaries?
For tumors diagnosed prior to 2007:
Code as 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.
First Course Treatment: What code is used to represent each treatment modality field when there is no indication that a particular modality of treatment was recommended or started?
Code the individual treatment fields to 0 or 00 [None] when the modality is not addressed in the treatment plan (or when a treatment plan is lacking) and there is no indication that a particular modality of treatment was recommended or started.
Histology (Pre-2007)--Breast: What code is used to represent the histology "duct carcinoma, colloid type"? See discussion.
Do we use 8480/3 [colloid carcinoma] or 8523/3 [duct carcinoma] mixed with other types of carcinomas?
For tumors diagnosed prior to 2007:
Code the Histology field to 8480/3 [colloid carcinoma] per Rule 4. The lesion is colloid type of ductal carcinoma, not ductal carcinoma mixed with colloid 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.
EOD-Extension--Cervix: How do you code tumor extension described as "the in situ lesion extends from the cervix to the mucosa of the vagina"? See discussion.
Example: Cone biopsy of cervix and vaginal vault both show ca in situ. The op report stated: "lesion extending from the left lateral portion of the cervix onto the left lateral portion of the vagina." The pathologist stated it "appeared to be an in situ lesion extending from the cervix to the mucosa of the vagina."
For cases diagnosed 1998-2003:
Code the Primary Site to C53.9 [Cervix uteri] and the EOD-Extension filed to 00 [in situ]. In situ is a measurement of invasion. Extension of the cervical in situ carcinoma via the mucosa to the vagina does not affect the EOD extension code.
