Surgery of Primary Site/Other Cancer-Directed Therapy--Head & Neck (Nasal cavity): Should a small fragment of bone removed during a maxillectomy following a turbinectomy for a nasal turbinate primary be "partial or total removal with other organ" for coding this field? See discussion.
Excision of a turbinate mass and partial turbinectomy revealed melanoma of the rt nasal turbinate. A subsequent rt medial maxillectomy was performed and a small fragment of bone was included in the resection and identified in the pathology report. Would the removed bone be "connective or supportive tissue" only for a Surgery of Primary Site code of 40 or is it another organ for a code of 60?
The piece of bone was likely removed to access the maxillary sinus and would not be a separate organ. Use the "All Other Sites" surgery coding schemes to code this primary. For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 40 [Total surgical removal of primary site]. Code the Surgical Procedure of Other Site field to 2 [Non-primary surgical procedure to other regional sites]. The maxillectomy was not performed in continuity to the turbinectomy and should be coded in this field rather than the Surgery of Primary Site field.
Date of Diagnosis/EOD-Extension--Placenta: How do you code these fields for a patient who presents with a vaginal metastatic lesion for a placenta primary? Should EOD-Extension be coded to 60 [Other genital structures NOS: vagina, ovary, broad ligament, fallopian tube] or 85 [metastasis other than lung]? See discussion.
Pt had D&C Feb 5 with features of complete mole. On March 7, pt seen for a mass just inferior to the urethral meatus. At path, vaginal introitus fragments were consistent with choriocarcinoma. At time of March 23 admit for chemo, history is given as large hydatidiform mole evacuated Feb 5. Her beta hCG titers initially fell but approximately one month later hCG titers rose. At that time, she had an obvious vaginal metastatic lesion.
For cases diagnosed 1998 or after: Code the Date of Diagnosis field to March 7, which is the date that the choriocarcinoma was first diagnosed. There was no slide review or clinical statement that the first occurrence was obviously malignant. Therefore, the vaginal mets is not progression and is codeable as extension. Code the EOD-Extension field to 60 [other genital structures, NOS] according to the current EOD scheme for placenta. Even though the mass is discontinuous, it is still included in code 60 per the guidelines of the FIGO system on which the EOD is based.
Ambiguous Terminology/Reportability: How should the expressions "suspicious for but not diagnostic of" and "suspicious for the possibility of early invasive adenocarcinoma" be interpreted for reportability? Would the interpretation be different depending on the primary site?
For reportability, interpret "suspicious for but not diagnostic of" as NOT diagnostic of cancer.
The phrase "suspicious for the possibility of early invasive adenocarcinoma" may indicate that the case is in situ. If no further information is available, this is not reportable.
The site of the cancer diagnosis does not change the interpretation.
EOD-Extension--Hematopoietic, NOS: If a solitary plasmacytoma originates in the right tonsil and extends to the left tonsil, vallecula and hypopharynx, is extension still coded to 10 [localized disease, solitary plasmacytoma only]?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 10 [localized disease, solitary plasmacytoma only] for all cases of solitary plasmacytoma.
Grade, Differentiation--Breast: Should the Bloom-Richardson (BR) grade (low, intermediate, high) have a higher priority than terminology (i.e., well differentiated)? See discussion.
2. Poorly differentiated but grade II/III. Microscopic comment: Slides show infiltrating ca which is P.D. in that it forms no tubules, but is grade 2 out of 3 in the modified BR scheme. It is ductal type with large moderately pleomorphic tumor cells displaying few mitoses.
3. Invasive moderately differentiated duct cell carcinoma with the following features: Modified BR grade: III/III (2+3+3=8).
For cases diagnosed prior to 2004:
Code the example cases as follows:
1. Grade 2. Histologic grade terminology ("intermediate") has the highest priority.
2. Grade 3. Terminology ("poorly differentiated") has the highest priority.
3. Grade 2. Histologic grade terminology "moderately differentiated" has priority.
EOD-Extension--Pancreas: Can you explain the difference between code 10 [confined to pancreas] and code 30 [Localized, NOS]. See discussion.
For example, a CT scan mentions no extension beyond the head, body or tail of the pancreas and there is no surgical resection. Should we code extension to 10 or 30?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 10 [confined to pancreas] because a scan supported the finding of no extension beyond the pancreas.
If the abstractor reviewing the medical record has scans, op reports, and/or pathology reports stating that the tumor is confined to the pancreas, code extension to 10 [confined to pancreas].
However, if the medical record only provides a patient history from a physician stating that the patient had localized pancreas, code extension to 30 [localized, NOS]. The NOS codes are used only when there is not enough information to code the specific codes (in this case, 10 or 20).
EOD-Lymph Nodes--Head & Neck: When a physician provides only "Stage IV" (i.e., an abbreviated stage) for a right posterior tongue primary with lateral extension into the oropharynx and hypopharynx, can you assume "palpable" level 2, 3 and 5 lymph nodes are involved?
For cases diagnosed 1998-2003:
Code the EOD-Lymph Nodes field to 9 [Unknown], based on the information provided.
The physician's statement of an N category from a TNM may be used to determine lymph node involvement in the absence of other information. However, you cannot assume nodal involvement based on the incomplete staging information of "Stage IV" for a base of tongue primary. For this primary site, extension into the hypopharynx from this primary is equivalent to T4/Stage IV. Therefore you cannot assume the clinician's assessment of the case as Stage IV represents his assessment of lymph node involvement.
Primary Site: How do we code site when endometrioid carcinoma arises in "endometriosis"?
Code the Primary Site to where the endometriosis implanted, which may or may not be the endometrium. Endometrioid carcinoma can arise in the ovary, endometrium and other internal genital sites. The site/histology edit for endometrioid and ovary has been removed from the SEER edit set.
Tumor Markers--Breast: If the ERA/PRA results reported differ for separate breast specimens removed for a single primary, do we code the results as positive or negative?
For cases diagnosed 1998-2003:
Code both the Tumor Marker 1 and Tumor Marker 2 fields to 1 [positive] when a single primary breast tumor has both positive and negative ERA/PRA receptors.
