Report Question ID Question Discussion Answer Year
20041088 CS Extension/EOD Extension--Renal Pelvis: Primary site is renal pelvis with direct extension to the rt adrenal gland. What is the correct extension code?

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.

Assign CS Extension code 67 [Adrenal gland from renal pelvis] for adrenal extension from renal pelvis -- T4 and regional direct extension.

20041062 Histology (Pre-2007): Can we ever code this field using a more specific cell type from a metastatic site specimen rather than to a less specific cell type from the primary site specimen? See Discussion. The histology for a metastatic deposit biopsy is mucin-producing adenocarcinoma. This report states that the primary site is the stomach. It is more specific than the histology from the stomach biopsy described as adenocarcinoma, NOS.

For tumors diagnosed prior to 2007:

Code the histology for the case example to 8481/3 [mucin-producing adenocarcinoma], the more specific histology.

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.

20041075 CS Tumor Size: Can we take the size of a "polypoid" mass? See Discussion.

3/04 Colonoscopy: 4 cm semi-circumferential friable mass in sigmoid colon. Path: Tubulovillous adenoma indeterminate for malignancy. 4/04 Sigmoid Colectomy: 5 x 4 polypoid mass: WD Adenocarcinoma arising in a tubulovillous adenoma.

Define "Polypoid". Size of "polypoid" mass. Would the size be coded to 050 or 999?

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.If the pathology report confirms that the entire polyp is malignant, code the size of the polyp/polypoid mass. If the pathology report does not confirm that the entire polyp is malignant, code 999.

Code tumor size as 999 [Unknown] for the example above. Do not code the size of the polypoid mass in this example. The size given above is the size of the polypoid mass, not the size of the malignancy.

Polypoid means "Like a polyp.

20041058 Primary Site/Sarcoma--Breast: Is the primary site coded to C504 [upper-outer quadrant of breast] or C493 [ Connective, subcutaneous and other soft tissue of thorax ] for a tumor described as a "high grade soft tissue sarcoma present in the upper outer quadrant of breast"? If the sarcoma is primary in the breast, code the primary site to C504 [upper-outer quadrant of breast]. C500 - C509 includes soft tissue of breast. 2004
20041071 Histology (Pre-2007)--Breast: When the histology from a lumpectomy differs from that of a core needle biopsy, should the lumpectomy histology be coded? See Discussion.

Histology - Page 85 of the SPM 2004, Histology Type Coding Instructions, #2. Use the histology stated in the final diagnosis from the pathology report. Use the pathology from the procedure that resected the majority of the primary tumor.

Based on this rule, should the following case should be coded to Ductal Carcinoma (8500/31)?

Core needle bx: WD Infiltrating Ductal Carcinoma with focal lobular features. Lumpectomy: WD Invasive Ductal Carcinoma.

For tumors diagnosed prior to 2007:

Yes, code this case to 8500/31 [Well differentiated invasive ductal carcinoma]. Code the histology stated on the pathology report from the procedure removing the most tumor tissue. A lumpectomy will usually provide more tumor tissue than a core needle biopsy.

First, determine which specimen contains the most TUMOR tissue -- in this case the lumpectomy. Next, apply the histology coding rules to the diagnosis on that pathology report. The rationale is that a diagnosis from a smaller specimen will be less accurate and less representative of the true histology compared to a larger tumor specimen.

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.

20041026 CS Tumor Size--Ovary: The size of a cyst is not coded in this field. However, can the size of a "cystic mass" be coded in this field? See Discussion. The specimen consists of a cystic mass which weighs 1520 grams and measures 23 x 17 x 10 cm.

If the tumor is described as a "cystic mass" and only the size of the entire mass is given, code the size of the entire mass, because the cysts are part of the tumor itself.

Please note: Ovarian cancer stage is not based on tumor size.

CS Tumor Size--Breast: When the diagnosis is inflammatory carcinoma of the breast, must the CS tumor size always be 998? See Discussion.

I have no specific example of a situation; I am writing an edit check and wondering if there would be any exceptions to this rule.

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.No. For inflammatory carcinoma, code the size of the tumor in CS tumor size. Use code 998 [diffuse] when the tumor is stated to be "diffuse."

Page 27 in Part I of the CS manual will be corrected to define code 998 for breast as only "diffuse." The errata should be distributed in July 2004.

20041006 Multiple Primaries (Pre-2007)/Date of Diagnosis--Bladder: How is date of diagnosis coded when metastases consistent with a bladder primary are found more than a year after a diagnosis of non-invasive bladder cancer? See Description. A non-invasive papillary transitional cell carcinoma is removed by TURB in May 2002. In January 2003, a bone biopsy reveals metastatic transitional cell carcinoma consistent with bladder primary.

For tumors diagnosed prior to 2007:

Code a second bladder primary diagnosed in January 2003.

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.

20041086 Histology (Pre-2007)/CS Tumor Size/CS Extension--Colon: How are these fields coded if a 3 cm sessile polyp is snared and removed piecemeal during a colonoscopy and the path microscopic description indicates a polypoid lesion with foci of malignant transformation found associated with bundles of smooth muscles followed by a LAR with no residual invasive tumor but the final path diagnosis is stated to be a M.D. adenocarcinoma? See Discussion.

3/04 colonoscopy 3cm sessile polyp snared & removed piecemeal. Path Micro: Polypoid lesion consists of branching & complex neoplastic glands lined by tall columnar epithelial...These foci of malignant transformation are assoicated with large polygonal epithelial...associated with desmoplastic stromal reaction & neoplastic glands can be found associated with bundles of smooth muscle.

4/04 LAR: focus of residual HG dysplasia: no residual invasive tumor. Final path dx: MD adenocarcinoma. Physician staged: T2 N0 M0.

Histology: 8140 vs 8210

Tumor Size: 030 vs 999 vs 990

Extension: 12 vs 20

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 tumors diagnosed prior to 2007:

Based only on information provided:

Histology: 8210 [Adenocarcinoma in a polyp]

Tumor Size: 999 [Unknown]

CS Extension: 20 [Muscularis propria invaded]

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.

20041054 CS Extension--Prostate: For a tumor that is clinically inapparent, but a biopsy from the prostatic apex is positive, is this field coded to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)]?

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.

Yes. Code CS Extension-Clinical Extension to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)] for clinically inapparent prostate cancer with positive apex biopsy.
