EOD-Extension--Kidney: How would this field be coded when the pathology report shows a 20 mm surface neoplasm with smaller yellow metastatic implants on the surface of the kidney?"
For cases diagnosed 1998-2003: Code extension as 10 [Invasive cancer confined to kidney cortex]. Tumor involves the cortical surface of the kidney with separate surface lesions, but does not extend beyond cortex.
Primary Site/EOD-Size of Primary Tumor--Lung: If the only lung mass described in CXR is a "hilar mass," is the primary site coded to C34.9 [Lung, NOS] or C34.0 [Main Bronchus; incl. Carina]? Also, can the size of the hilar mass be used to code the size of tumor field?
Because the only description available is "hilar mass," code primary site as C34.0.
For cases diagnosed 1998-2003: Use size of mass for EOD-Size of Primary Tumor.
Reportability--Pancreas: Is a solid pseudopapillary neoplasm of the pancreas reportable?
Solid pseudopapillary neoplasm of the pancreas is reportable. According to the WHO classification, it is a "low-grade malignant neoplasm…[which] frequently undergoes hemorrhagic-cystic degeneration and occurs predominantly in young women."
Assign topography code C25 with the appropriate 4th digit. Code the histology as 8452/3.
Primary Site--Breast: If a patient has multifocal tumors all in the upper outer quadrant of the breast, is the primary site coded to C-504 because all of the tumors are in UOQ or would the site be coded to C509 to reflect the fact that multiple tumors exist?
Code the primary site to C504 [Upper outer quadrant]. All disease is located in one quadrant, code that quadrant. When disease involves two or more quadrants and the point of origin cannot be determined, code C509 [Breast, NOS]. See 2004 SEER manual, page C-470 for instructions about invasive and in situ in different quadrants.
Reportability--Brain and CNS: Is a skull tumor schwannoma an intracranial reportable benign tumor if the physician states it arose in the occipital nerve?
No. These schwannomas are not intracranial and therefore, are not reportable to SEER. The occipital nerve is not one of the 12 intracranial nerves (i.e., Abducens, Auditory (vestibulocochlear), Facial, Glossopharyngeal, Hypoglossal, Oculomotor, Olfactory, Optic, Spinal Accessory, Trigeminal, Trochlear, and Vagus).
CS Extension/CS Mets at Dx--Lung: How are these fields coded for bilateral pleural effusion for a right lung primary? A code of 72 in the CS Extension field leads to a T4, but bilateral pleural effusion is M1. Should CS Mets at Dx be coded 39?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
For bilateral malignant pleural effusion, code the ipsilateral malignant effusion in CS Extension and the contralateral malignant effusion in CS Mets at Dx. Assuming the bilateral pleural effusion is the furthest extension in this case, code CS Extension to 72 [Malignant pleural effusion]. Code CS Mets at Dx to 40 [Distant mets, NOS].
Flag: For cases diagnosed prior to 2001, how is the ICD-O-3 Conversion Flag set if the ICD-O-2 and ICD-O-3 histology and behavior fields are both directly coded, as registrars in this region are instructed to do when submitting late cases, and as a result no conversion is necessary? Is it to 0 [Morphology (Morph--Type&Behav ICD-O-3 originally coded in ICD-O-3)] or Blank [Not converted]?
Assign code 3 [converted with review].
In your scenario above, ICD-O-2 and ICD-O-3 are being independently coded which should yield the same result as converting the case and then reviewing it.
Otherwise, if there is an ICD-O-3 code which differs from the ICD-O-3 code based on the conversion criteria, it will trigger an edit.
Histology (Pre-2007)/Behavior Code/Sequence Number-Central -- Ovary: How are these fields coded for a "serous tumor of low malignant potential" when lymph nodes are discovered to be involved?
For tumors diagnosed 2001-2006:
This ovarian tumor is not SEER reportable if diagnosed between 2001-2006. The histology and behavior codes are 8442/1 [serous cystadenoma, borderline malignancy]. Sequence is coded appropriately from 60-88 [non-malignant tumor or central registry-defined neoplasm].
The behavior code could be changed to /3 only when the pathologist states that the disease is malignant. Approximately 20% of serous tumors of low malignant potential have lymph node involvement, according to the WHO Classification of Ovarian Tumours. In ovarian serous tumors of low malignant potential, lymph node involvement is not always equivalent to metastasis and does not signify malignancy in these tumors unless definitely stated as such by the pathologist.
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.
CS Mets at Dx/CS Mets Eval--Colon: Would the metastasis field be coded to 00 [No; none] and the evaluation field be coded to 1 [No path exam of metastatic tissue performed.] when the source of information is from the operative findings for the following 6 different cases? 1) Liver normal; 2) No evidence of metastatic disease; mesentery normal, 3) Small ascites; no liver metastasis, mass adherent to duodenum without obvious invasion, 4) No mets or local invasion, 5) No evidence of carcinomatosis, peritoneal studding or malignant effusion and 6) Tumor adherent to lateral sidewall (path negative); no evidence of metastatic implants.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
The CS Mets Eval code refers to the method used to evaluate the site farthest from the primary site. The correct code may not be the highest eval code. For example 1 above, if the liver is the site farthest from the colon primary that was evaluated for distant mets, code the CS Mets Eval code to the method used to evaluate liver. Code surgical evaluation as 1.
Assuming this is all of the information about possible distant metastatic sites for the examples above, code CS Mets at DX as 00, and CS Mets Eval as 1 for each.
Please note: imaging of farther sites should also be included when CS Mets at DX is coded. For example, if there was also a negative chest X-ray, the CS Mets at DX field would be 00 but the CS Mets Eval field would be 0 because the CXR documents that there are no mets beyond the immediate area of the tumor.
