Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Kidney: How many primaries, with what histology(ies) should be coded when nephrectomy pathology specimen shows separate tumors of "renal cell carcinoma [clear cell type]" and "renal cell carcinoma [granular cell type]"?
For tumors diagnosed prior to 2007:
Abstract two primaries. This is an example of two tumors with different histologic types in the same site. The right kidney has two separate tumors.
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.
Surgery of Primary Site/Surgery Codes, NOS--Pancreas: What exactly is an extended pancreatoduodenectomy? Must the entire pancreas be resected in order to use code 70? What minimal requirements must be met to use code 70? How should a Whipple with cholecystectomy, partial omentectomy, common hepatic excision, portal vein resection, and lymphadenectomy be coded?
According to our research, a pancreaticoduodenectomy (PD) includes an en bloc resection of the pancreatic head, the common bile duct, the gallbladder, the duodenum, the upper jejunum, the distal portion of the stomach and the adjacent lymph nodes. The extended PD procedure includes extended lymphadenectomy, extended organ resection, and extended vascular resection and reconstruction.
Code 70 could be assigned without the entire pancreas being resected.
A Whipple procedure removes the head of the pancreas, duodenum, stomach and gallbladder and part the common bile duct. The portal vein resection is probably part of the common bile duct excision. If the omentectomy was performed for treatment of this primary, record it in "Surgical Procedure of Other Site." Record the lymphadenectomy in the lymph node data items.
MP/H Rules/Multiple primaries--Bladder: Is this a single primary or multiple primaries? Transurethral resection of the bladder identifies two bladder tumors. Pathology states one is high grade papillary carcinoma (8130/3) and the other is lymphoepithelioma-like urothelial carcinoma (8082/3). Lymphoepithelioma-like is listed as a urothelial type in Table 1 but rule M6 does not include it in the list of histologies and we are not told to refer to Table 1. M8 refers to Table 1 but does not include multiple bladder tumors (C67_). Specify which rule would apply and why.
Rule M9 applies to this case. Abstract two primaries. M6 does not apply to this case because code 8082 is not one of the applicable histology codes for M6. This situation will be reviewed as we prepare the next version of the rules.
CS Site Specific Factor--Breast: If the tumor is described as being a 1 cm poorly differentiated pleomorphic lobular carcinoma with scattered LCIS in breast tissue, for SSF6, do we use the breast tumor or all of the breast tissue removed when coding SSF6?
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.
Site Specific Factor 6 in the breast scheme describes the relationship of invasive and in situ tumor in the tumor size coded. Code SSF6 for the same tumor used to code tumor size.
For this example, code SSF6 for the 1 cm tumor. In this case, the entire tumor is reported as invasive; use code 000 [Entire tumor reported as invasive].
CS Site Specific Factor--Prostate: Explain the difference among SSF4 prostate codes 150 [No clinical involvement of prostatic apex & prostatectomy apex extension unknown], 510 [Clinical involvement of prostatic apex unknown & No prostatectomy apex extension], and 550 [Clinical involvement of prostatic apex unknown & prostatectomy apex extension unknown].
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.Site Specific Factor 4 captures the status of clinical apex involvement and prostatectomy apex involvement. The first digit in codes 110-550 indicates the clinical status of apex involvement. The second digit indicates apex involvement found at prostatectomy. The third digit is always zero. For both first and second digits, the codes and definitions are the same:
1 - No involvement of prostatic apex
2 - Into prostatic apex/arising in prostatic apex, NOS
3 - Arising into prostatic apex
4 - Extension into prostatic apex
5 - Apex extension unknown
Code 150 = No clinical involvement of prostatic apex & prostatectomy apex extension unknown
Code 510 = Clinical involvement of prostatic apex unknown & No prostatectomy apex extension
First course treatment/Radiation Therapy--Prostate: How do you code fiducial markers for prostate cases?
Do not code fiducial markers as a form of radiation treatment; rather, code the radiation therapy in the radiation treatment section. Fiducial markers are small metal spheres, coils, or cylinders that are placed in or near a tumor to help guide the placement of radiation beams during treatment.
Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C779 or C809 when a patient is diagnosed at another facility with mantle cell lymphoma and the staging bone marrow biopsy performed at this facility is negative? There is no available information concerning where the lymphoma originated.
Per PH Rule22, code the primary site to C779 [lymph nodes, NOS].
Rule PH22 is a default rule for lymphomas that is used when there is no other information regarding the primary site and the Heme DB does not indicate a primary site under its Primary Site(s) section. Rule PH27, code the primary site to unknown [C809], does not apply. Only use C809 [unknown] as the primary site when there is no evidence of lymphoma in lymph nodes AND the physician documents that the lymphoma originates in an organ(s).
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
Reportability/Behavior Code--Soft Tissue: Is a final diagnosis of a forearm mass diagnosed as "Angiomatoid malignant fibrous histiocytoma [see note]" reportable? The NOTE reads "Angiomatoid malignant fibrous histiocytoma is a low grade borderline lesion with a tendency for local recurrence, but a very low potential for distant metastases." Is behavior /1 or /3?
Angiomatoid malignant fibrous histiocytoma is reportable with a behavior code of /3 according to ICD-O-3. The Final Diagnosis takes precedence over the "note."
CS Lymph Nodes/CS Mets at Dx--Melanoma: How are these fields coded if a sentinel lymph node biopsy reveals no malignancy but there is an aggregate of melanoma cells in the lumen of a large vein immediately adjacent to the lymph nodes?
This question was answered by the CoC:
Do not count this as regional metastatic disease since there is no evidence it is an established tumor. Stage this as a N0.
Laterality--Breast: Should laterality be coded to 9 [Paired site but no information concerning laterality] or to the side with the positive lymph nodes for a case in which no breast mass is found but positive axillary lymph nodes are found on only one side?
Code laterality of the primary site to the side with the positive nodes when there are unilateral positive nodes and the laterality of the primary site is otherwise unknown.
