EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: Should a lymph node biopsy be counted in these fields or are these fields for lymph node dissections only? See discussion.
These fields record the number of regional lymph nodes examined pathologically whether from a biopsy or from a dissection. If the single lymph node biopsied was a regional lymph node, code the Number of Regional Lymph Nodes Positive field to 05 and the Number of Regional Lymph Nodes Examined field to 16. If the lymph node biopsied was a distant node, code these fields to 04 and 15 respectively.
CS Extension--Prostate: How do you code clinical extension for prostate primaries diagnosed at autopsy? See discussion.
A patient was not diagnosed prior to autopsy. The autopsy diagnosis states that this is adenocarcinoma of the prostate without capsular invasion.
Should clinical extension be coded to clinically inapparent, NOS (10) and pathologic extension be coded to no prostatectomy done within first course of treatment (97)?
Code CS Extension (clinical) to 99 [Unknown]. Code SSF 3 according to the amount of tumor found using the information from the autopsy.
EOD-Size of Primary Tumor--Breast: For breast cancer cases, is code 002 [Mammography/xerography diagnosis only with no size given (tumor not clinically palpable)] to be used only when there is no work-up beyond a clinical one? See discussion.
Usually when a mammogram has a malignant diagnosis, the tumor is clinically palpable, but occasionally the tumor is not palpable.
For example, on the mammogram, lesions are identified in the breast. PE--the breasts are palpably normal. Breast biopsies--two ductal carcinomas, no statement of size. Mastectomy--no residual. Should the size be coded to 999 rather than 002?
For cases diagnosed 1998-2003:
In the case you provided, code the EOD-Size of Primary Tumor field to 002 [Mammography/xerography diagnosis only with no size given (tumor not clinically palpable)]. A known code in the size field should always take precedence over 999 [Not stated]. Code size from the records in priority order as stated in EOD, from pathology, op report, PE, mammogram, etc. (See EOD for complete instructions.)
Code size as 999 only when there is a clinically palpable lesion with no size stated in the path, PE, or mammogram.
If there is a lesion seen on mammogram that is not clinically palpable, a stated size taken from the path or mammogram would take precedence over code 002; however, if there is no stated size, use code 002 rather than 999.
Place of Birth: When there is conflicting information, which record takes precedence in coding this field, the medical record or the death certificate?
If there is a discrepancy, use the information from the medical record to code the Place of Birth field. The information from the medical record is provided by the patient, the information on the death certificate is provided by others. If the medical record does not contain birth information, use the information from the death certificate.
EOD-Lymph Nodes--Lung: What code is used to represent this field when the only information is a description of:
1. "hilar mass"
2. "mediastinal mass"
3. "enlarged" or "greater than 1 cm" used to describe any of the lymph nodes listed under code 2 in the EOD Lymph Nodes field?
For cases diagnosed 1998-2003:
Code EOD-Lymph Nodes fields as follows for the examples given:
1) 9 [Unknown; not stated] for a "hilar mass"
2) 2 [Mediastinal] for a "mediastinal mass"
3) 2 [Mediastinal] for "enlarged" or "greater than 1 cm," if used to describe any of the named lymph nodes listed under code 2 in the EOD-Lymph Nodes field.
Grade, Differentiation: Are anaplastic tumors always coded to grade 4, even for anaplastic brain primaries?
Yes. Always code the Grade, Differentiation field to for 4 [Grade IV] for "anaplastic" tumors. Anaplastic is synonymous with undifferentiated. Refer to the example in the SEER Program Code Manual, 3rd Ed.
Histology (Pre-2007)/Grade, Differentiation--Brain and CNS: What code is used to represent the histology and grade for "WHO-II astrocytoma, grade II" of the brain when the WHO-II classification is different from the classification systems previously used? See discussion.
According to the WHO-I classification system, this is a moderately anaplastic astrocytoma. According to the Duke criteria, this is an astrocytoma. By Dauma-Dupont criteria, this is a grade 2 astrocytoma.
For tumors diagnosed prior to 2007:
Code the Histology and Grade, Differentiation fields to 9401/34 [anaplastic astrocytoma].
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--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.
EOD-Size of Primary Tumor--Breast: If the patient has inflammatory carcinoma of the breast, is the tumor size coded as 998 even though we have a tumor size?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary tumor field to 998 [Diffuse; widespread; 3/4 or more of breast; inflammatory carcinoma] for all inflammatory breast carcinomas.
These cases have a worse prognosis because of the dermal lymphatic invasion. Half of the inflammatory breast carcinomas will have no palpable mass.
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: How are these fields coded if radiation to the primary site and/or regional lymph nodes is performed prior to surgery?
For cases diagnosed 1998-2003:
Code the EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined fields per the information in the pathology report(s). Radiation to the primary site would not affect the status of the lymph node involvement. Radiation to the regional lymph node region may or may not affect the pathologic status of the lymph nodes. However, for these fields code the best information available about the status of the lymph nodes which is reflected in the pathology report(s).
