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.
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-Size of Primary Tumor--Lung: Can tumor size of 002 [Malignant cells present in bronchopulmonary secretions] be used when there is a lung mass seen but the diagnosis is from a positive bronchopulmonary secretion?
For cases diagnosed 1998-2003:
EOD-Size of Primary Tumor code 002 [Malignant cells present in bronchopulmonary secretions] is used only when there is no visible primary lung tumor and bronchopulmonary secretions are positive for lung malignancy.
Even if the diagnosis was made by cytology of broncho-pulmonary secretions, if there is a visible mass, code the size of the mass if known, code 999 if size is unknown.
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-Extension: General instructions, page 7, note 3 states: " Extent of disease information obtained after treatment with neoadjuvant chemotherapy, hormone or immunotherapy has begun may be included." Because the SEER manual does not mention radiation treatment, can we use information from a lobectomy to code EOD if a patient has neoadjuvant radiation therapy?
Radiation therapy was inadvertently omitted from the list. Please see SINQ 20031012 answer as to when the surgical information can be used to stage the case.
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.
EOD-Extension--Ovary: What code is used to represent this field for an ovarian primary presenting with "spread to the omentum"?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 75 [Peritoneal implants, NOS] because the size of the implants on the omentum is not known.
Note 6 was added to the EOD scheme which states that both direct extension and discontinuous metastasis to the omentum are coded in the range 70-75 depending on how the peritoneal implants are described.
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-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.
EOD-Extension/EOD-Lymph Nodes--Kaposi Sarcoma: What code is used to represent this field for a Kaposi sarcoma with no skin lesions but positive lymph node and bone marrow biopsies?
Code the EOD-Extension field to 13 [Visceral (e.g., pulmonary, gastrointestinal tract, spleen, other)], because of the positive bone marrow. Code the EOD-Lymph Nodes field to 3 [Both clinically enlarged palpable lymph nodes (adenopathy) and pathologically positive lymph nodes], for the pathologically positive node.
Note: Potential revision of the extension scheme will be referred to SEER Medical Advisory Group (SMAG).
