EOD-Size of Primary Tumor: Can the term "filling defect" be used to code tumor size? See Description.
Site: Bladder
CT abd/pelvis: 4 cm filling defect of the bladder encasing jetstream of distal ureter. 2-3 cm lesion may be extension to bladder. KUB: 3-4 cm filling defect within bladder.
Cystoscopy: large bladder tumor with small tumor extending out of the large tumor.
OP Findings: Large tumor on right of bladder extending from bladder neck lateral and posterior
Pathology: TURB: High grade TCC, Grade III with focal lamina propria invasion.
For tumors diagnosed 1998-2003:
Information on size from imaging/radiographic techniques can be used to code size when there is no more specific size information from a pathology or operative report, but it should be taken as low priority, just above a physical exam.
The term "filling defect" from a CT or KUB may be used to code tumor size for bladder in the absence of more reliable size information from path, operative or endoscopic reports.
Surgery of Primary Site--Skin: Should this field be coded to 45 [wide excision or reexcision of lesion or minor (local) amputation with margins more than 1 cm, NOS], 46 [with margins between 1 and 2 cm], or 47 [with margins greater than 2 cm] for a skin primary diagnosed in 2003 when margins are stated exactly as 2 cm?
Use code 46 [Wide excision...with margins more than 1 cm and less than 2 cm] when margins are exactly 2 cm.
EOD-Extension--Thyroid: Is this field coded as involvement of the thyroid capsule if the thyroidectomy path specimen reveals papillary thyroid ca "tumor present within capsular blood vessels?"
For cases diagnosed 1998-2003: Tumor present within the blood vessels of the thyroid capsule is localized (extension code 30). The tumor has not penetrated the capsule itself if it is contained within the blood vessels.
Keep in mind that tumor size determines the extent of disease for thyroid extension codes 10, 20, 30 and 40.
EOD-Extension--Melanoma: Is "erosion" synonymous with "ulceration" for melanoma cases?
For cases diagnosed 1998-2003:
No, do not interpret the term "erosion" as a synonym for "ulceration" when coding the EOD-Extension field for melanoma. According to AJCC's melanoma curator, erosion is not necessarily the same as ulceration.
EOD-Size of Primary Tumor: Can you code the tumor size if you have the aggregate size given for two or more tumor masses?
For cases diagnosed 1998-2003:
No. Never code the aggregate size in the Size of Primary Tumor field when the pieces removed come from TWO OR MORE tumors. If there is a clinical statement regarding the size of two or more tumors, code this field to the size of the largest tumor.
The aggregate size can only be used to code the Size of Primary Tumor field when the PATHOLOGIST estimates the size of the tumor from the pieces of ONE tumor removed by the surgeon.
Surgery of Primary Site--Bladder: Do we code "random bladder biopsies" as an excisional biopsy (27) or as no cancer directed surgery (00) even if the only involvement mentioned on the pathology reports is "focal carcinoma in situ"?
Code the Surgery of Primary Site field to 00 [None; no surgery of primary site] when only random biopsy procedures are performed on the bladder.
Reportability--Hematopoietic, NOS: Should we add the missing terms listed in the Abstracting and Coding Guide for the Hematopoietic Diseases to ICD-O-3 because these absent synonyms would not be identified during hematology casefinding? See discussion.
The Abstracting and Coding Guide for the Hematopoietic Diseases gives a preferred term for each code followed by a list of synonyms, not all of which are listed in the ICD-O-3. Two examples are: 1) 9962/3 [Essential Thrombocythemia] has 6 synonymous terms listed, but the last three of them are not in ICD-O-3. 2) 9930/3 [Myeloid Sarcoma] has the synonym "extramedullary myeloid tumor" which is not in ICD-O-3.
For cases diagnosed prior to 1/1/2010:Do not add these synonyms to ICD-O-3. The Abstracting and Coding Guide for the Hematopoietic Diseases lists synonyms for the preferred terms to assist in the classification of these other terms. In the absence of a specific code for the synonym, code to the preferred term. For casefinding, these terms would be grouped in a broader category of hematologic diseases under an ICD-9-CM or ICD-10 code and, therefore, will be identified during casefinding procedures using the disease index.
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.
Histology (Pre-2007)/Grade, Differentiation--All Sites: When the original pathology reports diagnosis indicates a grade and the review of slides (ROS) pathology report does not give a grade, can you code the histologic type from the ROS and the grade from the original pathology report? See discussion.
For example, if the original diagnosis is "poorly differentiated carcinoma" and the ROS diagnosis is "squamous cell carcinoma," would the morphology code be 8070/33?
For tumors diagnosed prior to 2007:
Yes. Code the Histology and Grade, Differentiation fields to 8070/33 [poorly differentiated squamous cell carcinoma]. Code the higher grade when different grades are specified for the same specimen and code the more specific morphology (i.e., squamous cell carcinoma rather than 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.
EOD-Lymph Nodes: If chemotherapy or radiation is given prior to the excision of an involved lymph node, should the size of the metastasis within the lymph node be coded from the subsequent surgical pathology report? See discussion.
For several sites, the size of the metastasis in an involved lymph node is integrated into the EOD-Lymph Node field. Should the size of the metastasis mentioned on the pathology report be ignored if the patient received radiation or chemotherapy prior to having the lymph node removed?
For cases diagnosed 1998-2003:
Record the size of a lymph node metastasis described in the pathology report for cases that had pre-surgical treatment. However, if both the pre-treatment and post-treatment size of the lymph node metastases are available, use the larger size when coding the EOD-Lymph Node field.
Primary Site--Ovary/Peritoneum: How should the Primary Site field be coded when no resection is done and it is uncertain whether the primary site is in the ovary or the peritoneum? See discussion.
CT: ascites, omental cake and peritoneal studding. H&P impression: probable ovarian or peritoneal primary. Repeat CT: no enlarged adnexal mass seen to suggest ca of ovary, but possibility couldn't be ruled out. Omental bx: Metastatic ca. Comment: "IHC stains have been performed and are not typical of ovarian ca, although do not exclude an ovarian primary." After the bx, there were two clinical diagnoses written a month apart with no evidence of further work-up between those dates. The first diagnosis was "ovarian ca". The second was "Peritoneal carcinomatosis 2 month ago; Primary is unknown, possibly ovarian."
Use the best information available to identify the primary site. In this case, it is the physician's clinical assessment. Code the Primary Site to C56.9 [Ovary] for this example because the ovary is indicated to be the primary site according to the physicians involved.
When there is no surgical procedure involving the removal of the ovaries, code the Primary Site based on the clinical assessment of the disease location. If the disease is only noted to be in the peritoneum, code site to peritoneum, NOS. If the disease is seen clinically in both the ovary and the peritoneum, code site to ovary.
