Reportability--Melanoma: Is the final diagnosis for an excisional skin biopsy of "compound nevus with severe cytoarchitectural atypia and regression" reportable if a re-excision may be clinically indicated because there is an "overlap of morphology between malignant melanoma and nevi with severe atypia, and there's evidence of regression"?
Compound nevus with severe atypia is not reportable unless also stated to be malignant melanoma or melanoma in situ.
Reportability: Is an AIN III that arises in perianal skin, skin tags or condyloma acuminatum reportable or must an AIN III arise in the anus or anal canal in order to be reportable?
AIN III arising in perianal skin [C445] is not reportable.
AIN III [8077/2] of the anus or anal canal is reportable.
Histology/Polyp--Colon: Which histology code is used when a colon biopsy states adenocarcinoma arising in a polyp, but the resection path states only adenocarcinoma, and does not mention arising in a polyp. See Discussion.
This scenario occurs frequently and our QC staff is divided on which code to use.
03-24-06 Rectal Polyp: Adenocarcinoma, moderately differentiated. 6-29-06 Rectum: Adenoca, MD, invades into the submucosa. No malignancy (0/15) LNs.
Use the polyp information from the biopsy and code adenocarcinoma arising in a polyp (8210, 8261 or 8263 as appropriate).
CS Extension--Pancreas, Head: When a tumor is described as having "vascular encasement of the celiac artery", is extension coded to 68 [tumor is inseparable from the celiac axis]?
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.
Code vascular encasement of the celiac artery to CS extension code 68 [tumor is inseparable from the celiac axis].
This celiac axis is a small (1cm) area of branching arteries. The celiac artery branches into hepatic, gastric, and splenic at the axis. Dissecting tumor out from around the celiac axis is very tricky and usually encasement by tumor is a sign of inoperability.
CS Extension--Lung: If only a "single" cytology is performed on pericardial fluid and it is negative, can Note 6 B, which states that pleural effusion [code 72] is coded as malignant unless there are "multiple" negative cytologies, be used to infer that the pericardial fluid should also be coded as involvement?
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, do not apply the instructions for pleural effusion to pericardial effusion. Do not code a pericardial effusion proven negative by cytology in CS Extension.
CS Extension--Lymphoma: If bilateral tonsils are involved with lymphoma, is it one or two regions of involvement and how is extension coded?
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 cases diagnosed 1-1-08 and later: Assign CS extension code 10 [involvement of a single lymph node region]. Bilateral tonsils are one organ/site.
See Note 1 under CS Extension. Tonsil is coded the same as a lymph node region.
Reportability/Behavior--Hematopoietic, NOS: Is a "myelodysplastic/myeloproliferative disease, unclassifiable" coded to 9975 with a behavior code of 3 as indicated in the WHO blue book on "Tumours of Haematopoietic and Lymphoid Tissues" or is it not abstracted because it has a behavior code of 1 which means the case is not reportable?
For cases diagnosed prior to 1/1/2010:Code MDS/MPD U to 9975/3 [Myelodysplastic/myeloproliferative disease, unclassifiable]. Change the behavior code to /3 according to ICD-O-3 Rule F. The case is reportable.
The WHO book is more recent and gives a specific code for this new hybrid category of the WHO/REAL classification.
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)--Bladder: How is a "carcinoma with squamous, mucinous, and signet ring cell features" coded?
For tumors diagnosed prior to 2007:
Code histology to 8490 [Signet ring cell carcinoma]. Rule 7 on page 87 of the 2004 SEER Manual applies to this case.
Rule 7: Code the numerically higher ICD-O-3 code. This is the rule with the lowest priority and should be used infrequently.
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.
CS Site Specific Factor--Prostate: Can autopsy results also be used when coding SSF3, pathologic extension, given that the instructions only address the use of prostatectomy findings when coding this field?
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 prostate cancer was diagnosed on autopsy, or the autopsy was performed within the staging timeframe (See 2004 SEER Manual, page 112), code SSF3 using the autopsy information.
Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?
Assign code 1 [Positive histology]. For leukemia only, assign code 1 for positive hematologic findings including peripheral blood smears, CBCs and WBCs.
Cytogenetics studies would have been done on blood. Therefore, histology provided diagnostic confirmation as it would with smear, bone marrow, or other special study of blood cells.
