Reportability--Hematopoietic, NOS: Is "evolving" multiple myeloma reportable to SEER?
For cases diagnosed prior to 1/1/2010:No, it is not SEER reportable. The diagnosis of "evolving" multiple myeloma could represent a plasmacytoma, plasma cell dyscrasia or another lymphoproliferative disorder. Some of these histologies are SEER reportable, but some are not. Additional information would be needed to determine reportability. If you are unable to obtain more information, the case is non-reportable.
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.
Surgery of Primary Site--Breast: How is this field coded when a patient has a reduction mammoplasty (for macromastia) and within the pathology specimen there is an incidental finding of carcinoma?
Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.
Multiplicity Counter: Are in situ tumors diagnosed more than 60 days after invasive tumors of the same site and histology included in the Multiplicity Counter?
If an in situ tumor following an invasive tumor is a single primary according to the multiple primary rules for that particular site, include the in situ and the invasive tumors in the multiplicity counter.
Date of Diagnosis--Sarcoma: Should the date of diagnosis be coded to the date of biopsy or the date of birth for an infant biopsied at 3 days of age and stated to have a diagnosis of congenital alveolar rhabdomyosarcoma, widely metastatic?
Code the date of the biopsy as the date of diagnosis. This is the date the cancer was first identified by a medical practitioner.
Note: SEER collects the Month and Year of diagnosis. The "day" of diagnosis is not collected by SEER.
Reason for No Cancer-Directed Surgery--Lung: How do you code this field for a lung primary that presents with metastasis to the bone and brain in which the oncologist's treatment plan includes only radiation and chemotherapy?
Code the Reason for No Cancer-Directed Surgery field to 1 [Cancer-Directed Surgery Not Recommended].
Histology (Pre-2007)--Lung: Does 8070 [squamous cell carcinoma], 8560 [adenosquamous carcinoma] or 8255 [adenocarcinoma with mixed subtypes] best represent this field for a lung biopsy described as a "poorly differentiated non-small cell carcinoma with squamous and glandular features with focal mucin positivity per mucin stain"?
For tumors diagnosed prior to 2007:
Assign code 8560/33 [Adenosquamous carcinoma, poorly differentiated]. "Glandular" carcinoma is a synonym for adenocarcinoma. Mixed adenocarcinoma and squamous carcinoma is coded to 8560. Do not use code 8255 [Adenocarcinoma with mixed subtypes] when a more specific complex code is available.
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.
Ambiguous Terminology/Reportability: How should the expressions "suspicious for but not diagnostic of" and "suspicious for the possibility of early invasive adenocarcinoma" be interpreted for reportability? Would the interpretation be different depending on the primary site?
For reportability, interpret "suspicious for but not diagnostic of" as NOT diagnostic of cancer.
The phrase "suspicious for the possibility of early invasive adenocarcinoma" may indicate that the case is in situ. If no further information is available, this is not reportable.
The site of the cancer diagnosis does not change the interpretation.
MP/H Rules--Breast: What histology code is used for lobular carcinoma, pleomorphic type?
For cases diagnosed 2007 or later, use rule H14 and code the histology 8520 [lobular carcinoma]. 8520 is the only ICD-O-3 code for lobular carcinoma. There are no codes for specific lobular types.
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.
