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].
EOD Fields--All Sites: Is EOD information limited to what is available exactly two months from the day of diagnosis?
For cases diagnosed 1998-2003:
EOD should include all information available within four months of diagnosis in the absence of disease progression or through completion of surgery(ies) in first course of treatment, whichever is longer.
Mets known to have developed after EOD was established should be excluded.
Diagnostic Confirmation--Prostate: How do we code this field when there is an elevated PSA, no other work-up and there is a clinical diagnosis of adenocarcinoma?
Code the Diagnostic Confirmation field to 5 [positive laboratory test/marker study] to indicate the diagnosis is based upon an abnormal PSA tumor marker if the physician uses the PSA as a basis for diagnosing prostate cancer.
First Course Treatment: If the patient receives no treatment at the time of diagnosis (either because it is not recommended or because the patient refused treatment at that time) but treatment is later instituted after disease progression, should this treatment be coded as part of the first course of treatment?
The SEER rules changed in 1998 regarding what constitutes First Course of Cancer-Directed Therapy.
For cases diagnosed on or after 1/1/98: The First Course of Cancer-Directed Therapy fields will all be coded to 0 [None] for these types of cases. The documented disease progression would stop the timeframe for inclusion of any treatment to be part of first course of therapy.
Histology (Pre-2007)--Skin: Are "atypical melanocytic hyperplasia" and "severe melanotic dysplasia" synonyms for melanoma in situ?
For tumors diagnosed prior to 2007:
No. SEER determines its reportable list from the ICD-O-3. The above terms are listed as tumor-like lesions and conditions, but are not in situ or malignant.
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 a non-Hodgkin lymphoma presenting with involvement of an extralymphatic organ and lymph nodes on the opposite side of the diaphragm?
For cases diagnosed 1998-2003: Code the EOD-Extension field to 31 [30 + localized involvement of an extralymphatic organ or site; Stage III E].
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.
Surgery of Primary Site: Should laparoscopy be coded as exploratory surgery? See discussion.
Many surgeons are doing exploratory surgery with laparoscopy involving a very small incision, but they can examine organs and take biopsies. Should laparoscopy be coded as exploratory surgery?
For cases diagnosed 1/1/1998 and later: Exploratory surgical procedures, such as laparoscopic surgeries, are not coded in the Surgery of Primary Site field.
EOD-Pathologic Extension--Prostate: Can a pathological extension code be assigned when a retropubic prostatectomy is done? See discussion.
The TNM manual states, "Total prostatoseminalvesiculectomy and pelvic lymph node dissection are required for pathologic staging."
For cases diagnosed 1998-2003:
The pathology report from a retropubic prostatectomy should be used to code the Pathologic Extension field. This field is coded using pathology report information from the prostatectomy operation regardless of the surgical approach and regardless of whether or not a pelvic lymph node dissection was performed. This is one area in which TNM rules for pathologic staging and SEER rules for EOD are slightly different.
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).
