Reportability--Ovary: Is a Stage IIIC serous borderline tumor (micropapillary type) of the ovary diagnosed in 2003 reportable?
Serous borderline tumor of the ovary diagnosed in 2003 is not reportable to SEER. The behavior code is /1 in ICD-O-3. The high stage does not make this borderline tumor reportable.
Surgery of Primary Site--Head & Neck: How is this field coded for a surgery titled "Parotidectomy with facial nerve dissection"? See Description.
If the operative report is not titled "total parotidectomy," can we assume that less than total parotidectomy was done? Can we assume that "facial nerve dissection" and "facial nerve monitoring" are other ways of stating "facial nerve spared"?
Use the best information available to determine whether or not all of the parotid has been removed. It is important to read the entire operative report and review the content of the pathology report. The Op report will usually include wording about how much was removed, and this can be confirmed by the path report. Do not make assumptions about the extent of the surgery based solely on the title used on the operative report.
For cases diagnosed 1998-2003: Code 30 [less than total parotidectomy] can be used when the parotid is not totally removed, but the exact type of partial parotidectomy cannot be determined. "Facial nerve monitoring" and "Facial nerve dissection" are synonymous with "facial nerve sparing."
EOD-Extension--Lymphoma/Brain and CNS: How is this field coded for a primary brain lymphoma that is described as multi-focal?
For cases diagnosed 1998-2003: Since brain is the only site involved in this example, assign code 11 [Localized involvement of a single extralymphatic organ or site].
Ambiguous Terminology/Histology (Pre-2007): How do we code histology when there is a difference between the histology mentioned on a suspicious cytology and the clinical diagnosis by the treating physician? See Description.
An FNA of pancreas is stated as "highly atypical cells present, suspicious for pancreatic ductal carcinoma." The attending physician states the patient has pancreatic carcinoma. Can histology be coded 8500/3 [infiltrating duct carcinoma, NOS] or should it be 8010/3 [carcinoma, NOS]?
For tumors diagnosed prior to 2007:
Code the histology from a suspicious cytology when this histology is supported by the clinical diagnosis.
Code the example above to 8010/3 [Carcinoma, NOS].
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.
Other Cancer-Directed Therapy--Hematopoietic, NOS: Is there a hierarchy for selecting which code to use when a patient receives more than one type of "other treatment"? See Description.
Patient was diagnosed with Myelodysplastic Syndrome, probably refractory cytopenia with multilineage dysplasia. Good candidate for investigational studies for transfusion-dependent patients. Patient was enrolled in a high dose vitamin D study. Patient also received transfusions.
SEER has not established a hierarchy of the codes listed under Other Treatment. If the patient receives more than one type of other treatment as the first course of treatment, assign the code that provides the most information about how the patient was treated and use the remarks fields to explain.
Code Other Treatment for the case example above as 2 [Other experimental therapy]. Use the remarks fields to describe the transfusions and vitamin D therapy.
Date of Diagnosis/Diagnostic Confirmation: How are these fields coded when a physician statement of diagnosis predates a positive biopsy? See Description.
A mass seen on EGD with negative biopsy 12/28/01. Needle core biopsies 1/14/02 were diagnostic of GIST. Gleevec treatment was initiated 2/02, and in discharge summary 5/27/02, the physician says the GIST was diagnosed on EGD.
Code the date of diagnosis as 01/2002. Code the diagnostic confirmation as positive histology. EGD revealed a "mass." Biopsies of the "mass" seen on EGD were negative before January 2002.
EOD-Extension--Head & Neck: Is this field coded 10 [Invasive tumor confined to one of the following subsites: interior wall, one lateral wall, posterior wall] or 30 [Localized, NOS] for tonsillar primary when there is no mention of involvement of surrounding structures? See Description.
Site is stated to be "left tonsil" and was coded to site C099. "The lesion is admixed in tonsillar tissue." No surrounding structures are stated to be involved. Is it logical to assume that since code C099 includes the palantine tonsils and the palatine tonsils are on the lateral wall and since no other areas are stated to be involved that extension code 10 [confined to one lateral wall] would be more appropriate than code 30 [localized NOS]?
For cases diagnosed 1998-2003: Code EOD-extension for the case example to 10 [Invasive tumor confined to one of the following subsites: anterior wall, one lateral wall, posterior wall]. The tonsil lies in a pocket on the wall (tonsillar fossa), so you know it is confined to the wall.
Histology (Pre-2007)--Breast: Should the histology "non-invasive papillary carcinoma" along with the comment "solid intraductal papillary proliferation includes cytologically atypical cells with scattered mitotic figures" be coded to 8503/2 [intraductal papillary carcinoma] or 8050/2 [papillary carcinoma in situ]?
For tumors diagnosed prior to 2007:
The best histology code for this breast case is 8503/2 [Noninfiltrating intraductal papillary carcinoma]. According to the WHO Classification of Tumors for Breast, Papillary carcinoma, non-invasive is a synonym for Intraductal papillary carcinoma. Further, code a more specific histologic type when found in the microscopic description, according to the SEER Program Code manual.
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.
