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.
Reportability/Terminology, NOS--Hematopoietic, NOS: Is "smoldering" multiple myeloma reportable to SEER?
For cases diagnosed prior to 1/1/2010:Yes, "smoldering" multiple myeloma is reportable to SEER as multiple myeloma [9732/3].
According to our pathologist consultant, "smoldering" multiple myeloma would certainly refer to a diagnosed process. Smoldering means the process is progressing, but perhaps slowly, or even at a slower pace than might be expected.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
EOD-Extension--Lymphoma: How is the following guideline of "any mention of lymph nodes is considered indicative of involvement" applied for EOD-Extension of lymphoma cases when there is a discrepancy between physicians as to the stage at diagnosis? See discussion.
A biopsy of mesenteric nodes confirmed lymphoma. A bone marrow biopsy was negative. A CT of the chest indicates "small mediastinal and bilateral hilar nodes, but without convincing adenopathy." The case was Stage 2 per the oncologist and Stage 3 per the surgeon's TNM form.
For tumors diagnosed 1998-2003:
Based on the information provided for this example, the lymphoma involves one site, mesenteric nodes. Code EOD extension as 10 [Involvement of a single lymph node region].
The statement "For lymphomas, any mention of lymph nodes is indicative of involvement" refers to the terms in the paragraph above it on page 8 of the EOD manual: Palpable, enlarged, visible swelling, shotty, lymphadenopathy. While these terms are ignored for other malignancies, they should not be ignored for lymphomas. None of these terms apply to the example provided here. According to the CT, the mediastinal and hilar nodes are "small" "without convincing adenopathy." In other words, the mediastinal and hilar nodes are negative.
Laterality/Multiple Primaries (Pre-2007)--Ovary: Are ovarian primaries with bilateral involvement always coded to laterality 4 (bilateral)? See Description.
Example: "Right ovary with mass replacing majority of ovarian tissue consistent with serous adenoca. Lt ovary with foci of adenoca." No specific statement of primary. Can we assume that the malignancy originated in the right ovary since it is more extensively involved or should laterality be coded 4 because both ovaries have tumor?
For tumors diagnosed prior to 2007:
If one ovary is listed as the primary site, code laterality to that ovary. The example above is one of those times when you would code to the single ovary. The issue of one or both ovaries being involved is handled in staging.
Abstract the example above as a single primary with code 1 [Right] for laterality.
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.
Histology (Pre-2007)/Sarcoma: What code is used to represent the histology "Ewing's Sarcoma/Primitive Neuroectodermal Tumor (PNET)"? See Description.
A comment on one path report states "some authors consider both Ewing's & PNET to be the same biologic entity given that they share the same translocation between chromosomes 11 & 22." The pathologists at our children's hospital agree with this statement and contend that the two should have the same histologic code.
For tumors diagnosed prior to 2007:
Code histology as 9260/3, Ewing sarcoma. Ewing sarcoma is a specific histology on the continuum of primitive neuroectodermal tumors. Code Ewing sarcoma as it is more specific than PNET, 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.
Laterality--Head & Neck: Does the site code C098 need a laterality code? See Description.
In the SEER EOD-88 3rd edition, page 36, site code C098 does not need laterality. In the SEER Program code manual, 3rd edition, page 93, site code C098 is listed as a site that needs a laterality code 1-9.
Topography code C098 [Overlapping lesion of tonsil] requires a laterality code of 1-9. Follow the laterality guidelines in the SEER Program Code Manual.
Terms of involvement--Lung: Is "intense uptake" described on a PET scan an indication of involvement? See Description.
We are seeing increasing use of PET scans as diagnostic tools for cancer. PET scans use different terminology than the ambiguous terms listed in the EOD manual. Could we please have guidelines for interpreting PET scans?
Example: Patient with right lung cancer. PET scan showed intense uptake in the mediastinum and in the hilum. Can we code "intense uptake" as involvement of mediastinal and hilar lymph nodes?
Do not interpret "intense uptake" as involvement. Look for a statement of involvement or other terminology, such as "highly suspicious," "strongly suspicious for" malignancy, involvement, etc.
Histology (Pre-2007)--Kidney: Is 8316/3 [Cyst associated renal cell carcinoma] the appropriate code for 1) Cystic renal cell carcinoma, 2) Renal cell carcinoma mass with cystic areas and 3) Cystic renal cell carcinoma, clear cell type?
For tumors diagnosed prior to 2007:
Yes, ICD-O-3 histology code 8316 is the correct code for the three examples above.
There are two categories of cyst-associated renal cell carcinomas: Renal cell carcinoma originating in a cyst, and Cystic renal 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.
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--Skin: When would one use codes 30-33 for this field on a skin primary?
Surgery of Primary Site codes 30-33 under "skin" are used for various types of biopsies followed by a gross excision of the lesion. The two procedures (biopsy and gross excision) may be performed on different days, at different facilities, by different physicians as long as both procedures are performed during the first course of treatment.
Answer applies to both pre-2002 and 2003+ surgury code definitions.
