Histology (Pre-2007): What code is used to represent the histology "non-small cell carcinoma, NOS"? See discussion.
Should a non-small cell carcinoma histology be assumed to be a large cell carcinoma [8031/3] or should the histology be coded to carcinoma, NOS [8010/3]?
For tumor diagnosed 2001-2006: Code the Histology field to 8046/3 [non-small 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.
EOD-Size of Primary Tumor--Breast/Cervix: When coding tumor size, when do you use 997 for breast cases and 000 versus 999 for breast and other primaries? See discussion.
Example 1: Ductal carcinoma found in axillary lymph nodes. No tumor found in breast on physical exam or by pathological exam of the breast, but physician states that the breast is definitely the primary site.
Example 2: Paget disease for breast carcinoma with no underlying tumor.
Example 3: Inspection of the cervix shows no visible tumor; biopsy of the cervix reveals CIN III or squamous cell carcinoma, either invasive or in situ.
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field as follows:
Example 1: Code to 000 [No mass, no tumor found, no Paget disease] when a tumor of a stated primary site is not found, but the tumor has metastasized.
Example 2: Code to 997 [Paget disease of nipple with no demonstrable tumor] if there is no underlying tumor and the patient presents with Paget of the breast.
Example 3: Code to 999 [Size not stated] when no size of tumor is given on the pathology report. Do not use 000 in the size field when a tumor is not visible on physical exam or by imaging, but tumor is found microscopically.
EOD-Lymph Nodes/TNM--Breast: Do we code these lymph nodes fields for a breast primary that describes ipsilateral axillary lymph node involvement as "extending through the lymph node capsule and into perinodal soft tissue/fat" as "fixed/matted"?
For cases diagnosed 1998-2003:
Code the EOD-Lymph Nodes field to 6 [Axillary regional lymph nodes, NOS], if the size of the metastasis within the lymph node is not known. "Extension into perinodal soft tissue" does not imply that the lymph nodes are fixed to one another or to other structures. AJCC stage for lymph nodes is coded to N1 [Metastasis to moveable ipsilateral axillary lymph nodes].
In order to code the EOD-Lymph Nodes field to 5 [Fixed/matted ipsilateral axillary nodes] which is the equivalent to AJCC equivalent N2, there must be some clinical or pathologic statement of fixation or matting. There can be extension through the capsule without fixation or matting. "Fixation" is a clinical term and "matting" can be either clinical or pathologic. A pathologist can recognize two or more lymph nodes stuck together by tumor.
Primary Site--Esophagus: What is the difference between C15.5 [Lower third of esophagus] and C15.2 [Abdominal esophagus]?
These descriptions represent the use of two different ways the esophagus can be divided anatomically. The two different systems used are illustrated in the SEER Self Instruction Manual for Tumor Registrars: Book 4. Assign the primary site code that describes the location of the tumor in the same way the tumor's location is described in the medical record.
EOD-Clinical Extension--Prostate: How do you distinguish between clinical extension codes of 10, 13, 14, and 20 for cases with a benign prostate per digital rectal exam that appear localized after TURP/prostatectomy? Can the clinical extension code of 10 be used if the term "microscopic carcinoma" is noted in the pathology report without also mentioning "foci" or "Stage A" for clinically inapparent tumors?
For cases diagnosed 1998-2003:
When the prostate feels benign and the cancer is found incidentally at the time of the microscopic exam, code the EOD-Extension field to 10 [number of foci or % of involved tissue not specified]. Code as 13 (less than or equal to 5%) or 14 (greater than 5%) if percentage involved is given in the tissue resected. If the path report states "solitary focus of carcinoma" without mentioning the total amount of tissue resected, code extension to 13. If there is more than one focus, code extension to 10. Don't assign a code of 20 unless the tumor is clinically apparent.
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: What codes are used to represent these fields when only a regional lymph node (positive) aspiration is performed?
For cases diagnosed 1998-2003:
With the exception of those sites/histologies that require 99 in these fields, code the Number of Regional Lymph Nodes Positive field to 97 [Positive nodes but number of positive nodes not specified]. Code the Number of Regional Lymph nodes Examined field to 95 [No regional Lymph nodes removed, but aspiration of regional Lymph nodes was performed].
Surgery of Primary Site--Ovary: What code is used to represent this field when a patient has a history of a previous organ removal and has additional surgery/organ removal for a present cancer (e.g., History of a 1984 hysterectomy and in 2003 has ovarian primary treated with BSO)?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 52 [Bilateral salpingo-oophorectomy WITH hysterectomy].
EOD-Clinical Extension--Prostate: In the SEER EOD manual, there is a list of terms to distinguish apparent from inapparent tumor for prostate primaries. Are terms in the "maybe" category and are terms not on the list clinically inapparent or clinically apparent when there is no physician staging of the case? See discussion.
The rectal examination states that there is "asymmetrical enlargement of the prostate, firmness over the right lobe" and the physical exam impression is extensive carcinoma of right lobe. A needle biopsy of the right lobe was positive. "Enlarged" is on SEER's list of clinically inapparent terms; "asymmetrical" and "firm, NOS" are on the "maybe" list.
For cases diagnosed 1998-2003:
On the basis of the physical exam impression, code the EOD-Clinical Extension field to 20 [involvement of one lobe, NOS] for this case. Although the medical record did not provide a physician's staging of the case as clinically apparent, the physician did suspect carcinoma prior to the biopsy.
If clarifying stage information is missing and the term is in the "maybe" category or the term is not on the list, then code extension as 30 [localized, NOS] for cases that appear localized.
EOD-Extension--Lung: If a CT scan indicates that a patient has evidence of "long-standing pneumonia," is that synonymous with "pneumonitis" for the purposes of coding extension for lung primaries?
No. These terms are not synonymous. For cases diagnosed 1998-2003, disregard the pneumonia and use the other available information to code extension.
