Reportability--Skin: Is this case not reportable if the intranasal polyp is covered with cutaneous epithelium (essentially skin) or, is it reportable as a primary intranasal basal cell carcinoma? I have found one article regarding primary intranasal basal cells, which are described as being "very rare". But, I am not sure whether, in those cases, cutaneous epithelium was found.
FINAL DIAGNOSIS: (A) Nasal cavity, polyp, excision: Sinonasal inflammatory polyp with overlying cutaneous epithelium showing foci of superficial (noninvasive) basal cell carcinoma
Report this case as a basal cell carcinoma, noninvasive, of the nasal cavity, based on the information provided.
The polyp was removed from the nasal cavity (C300) which is a reportable site for basal cell carcinoma.
CS Extension--Extramedullary Plasmacytoma: Under what circumstance would CS extension code 80 be used in a case of extramedullary plasmacytoma?
For cases diagnosed prior to 1/1/2010, 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 80 [Systemic disease] for extramedullary plasmacytoma involving more than one site. Use code 80 when extramedullary plasmacytoma is NOT single, solitary, unifocal, isolated, mono-ostotic or localized. Code 80 can also be used when the bone marrow is involved but the plasma cells are <10%.
Do not apply EOD instructions to CS.
For cases diagnosed 1/1/10 and later, 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.
Primary site--Kidney, renal pelvis: Should primary site be coded C809 [unknown] or C649 [kidney] when a patient is diagnosed with renal cell carcinoma in a transplanted kidney?
Code the primary site to C649 [kidney]. Per the SEER Manual, code the site where the neoplasm originated. There are no separate instructions for coding primary site for transplanted organs. This patient's renal cell carcinoma originated in the kidney [C649].
Histology (Pre-2007)--Cervix: Is 8384/3 [adenocarcinoma, endocervical type] a specific histology type that must be stated or does it apply to any adenocarcinoma arising in the endocervical? Should the ICD-O-3 histology code of 8384/3 [Adenocarcinoma, endocervical type] be used for final diagnoses of "adenocarcinoma of the endocervix" or "adenocarcinoma of the cervix"?
For tumors diagnosed prior to 2007:
Histology code 8384 is for adenocarcinoma of endocervical type. This specific type (endocervical) must be part of the diagnosis in order to assign code 8384. This histology code is not to be used for Adenocarcinoma, NOS of the endocervix or cervix.
Adenocarcinoma of endocervical type can be diagnosed in other tissues and if so it will be stated as endocervical type. Adenoca of the endocervix would be coded to plain Adenoca.
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 Lymph Nodes/CS Site Specific Factor--Breast: When there are no lymph nodes removed and none palpable for an inflammatory breast cancer and the physician stages the case Nx, is the CS Lymph Node field code to 00 [None, no regional lymph nodes involved] or 99 [Unknown, not stated] and would SSF 4 and 5 be coded to 000 [Regional lymph nodes negative...] or 888 [Not applicable]?
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 Lymph Nodes 00 [clinically negative]. See note 3 for CS Lymph Nodes.
Reportability/Histology--Colon: Is tubular adenoma with high grade dysplasia and focal invasion from a pathology report of a colon biopsy reportable?; if so, what is the histology code?
Tubular adenoma with high grade dysplasia and focal invasion is reportable. Assign the histology code and behavior as 8210/3 (Adenocarcinoma in tubular adenoma).
NAACCR Guidelines for ICD-O-3 Implementation discuss the term high grade dysplasia (without invasion). High grade dysplasia and related terms are under review and study for consideration as a reportable neoplasm. Registries should check with their state reporting legislation to see if included in the reporting requirements.
CS Site Specific Factor--Head & Neck: If a lymph node dissection of the neck reveals that 1/24 lymph nodes is positive and the positive 5.6 cm lymph node extends throughout levels II-IV, how are the SSF 3 (status of levels I-III lymph nodes) and SSF4 (status of levels IV-V lymph nodes) fields 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.According to the CS Steering Committee, code 999 for SSF 3 and SSF 4. In this case, do not make assumptions about which level of lymph nodes were involved.
Reportability--Heme & Lymphoid Neoplasms: Is refractory iron deficiency anemia reportable?
Per Appendix F, refractory iron deficiency anemia is not reportable. It is not a clonal disorder and, therefore, is not malignant. Refractory iron deficiency anemia is a condition that is unresponsive to oral iron treatment.
Marital Status: Is marital status coded to 2 [married] if the patient is legally married to a same-sex spouse (e.g., patient has a Canadian spouse and in Canada, same-sex marriages are legal)?
Code marital status for same-sex persons based on the legal status. For the case example above, assign code 2 [married].
Histology (Pre-2007)--Breast: What code is used to represent the histology "invasive ductal carcinoma, mucinous type and invasive lobular carcinoma"?
For tumors diagnosed prior to 2007:
Code the Histology field to 8522/3 [infiltrating duct and lobular carcinoma] per rule 1 of the Coding Complex Morphologic Diagnoses, because the tumor is both lobular and ductal.
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.
