CS Site Specific Factor--Colon: If the patient has a polypectomy followed by definitive surgery, can a higher CEA reported after the polypectomy but before the colon resection be 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.If the tumor was in the polyp, do not use the post-polypectomy CEA even if it is higher than CEA's prior to the polypectomy. In this situation, the polypectomy would be treatment.
Conversely, if this is a frank adenocarcinoma or the tumor was so invasive that the polyp removed only a portion, use the post-polypectomy CEA because the polypectomy would not be treatment in this situation.
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.
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 Site Specific Factor 6--Breast: If the tumor size for the breast is unknown, and it is unknown whether the tumor is mixed in situ and invasive or "pure", how is SSF6 to be coded? See Discussion.
The definition for SSF6 for breast changed from "Unknown if invasive and in situ components present, unknown if tumor size represents mixed tumor or a pure tumor" to an added clarification of "Clinical tumor size coded." Since the clinical tumor size is NOT coded, this does not fit.
The definition for 060 is "Invasive and in situ components present, unknown size of tumor (CS Tumor Size coded 999). Since it is unknown if the tumor is mixed, this definition does not fit either.
It seems that the revised (April 2005) definition for 888 has left a situation that cannot be 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.SSF 6 should be coded 888 in this case. SEER will make the CS task force aware of this situation.
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 Eval--Prostate: How is CS Ts/Ext Eval to be coded for a clinically inapparent prostate cancer that is treated with Lupron and a subsequent prostatectomy? See Discussion.
Patient diagnosed with prostate cancer on biopsy for elevated PSA, CS extension code 15. Patient then receives 4 courses of Lupron. Subsequent radical prostatectomy shows bilateral lobe involvement with capsule invasion, SSF 3 pathologic extension code 032.
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 CS TS/Ext Eval 6 [surgical resection performed with pre-surgical systemic treatment, tumor size/ext based on path evidence]. For prostate, CS TS/Ext eval must reflect coding of CS extension and SSF 3. In this case, SSF 3 code 032 is based on the prostatectomy information which occurred after systemic treatment.
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.
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.
Ambiguous Terminology--Breast: Is a stereotactic biopsy that is "focally suspicious for DCIS" reportable if it is followed by a negative excisional biopsy? See Discussion.
Per the 2004 SEER manual page 4, 1.a, the case is reportable based on the ambiguous term "suspicious" for DCIS.
Per the 2004 SEER manual page 4, 1.c, use these terms when screening diagnoses on pathology reports, operative reports, scans, mammograms, and other diagnostic testing other than tumor markers.
Note: If the ambiguous diagnosis is proven to be not reportable by biopsy, cytology, or physician's statement, do not accession the case.
Do not accession this case. The needle localization excisional biopsy was performed to further evaluate the suspicious finding found on stereotactic biopsy. The suspicious diagnosis was proven to be false.
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.
