Reportability--Hematopoietic, NOS: The Abstracting and Coding Guide for the Hematopoietic Diseases, page 47, states to determine whether the physician is using the term myelodysplasia to describe bone marrow marrow malfunction or a neoplasic syndrome in order to determine reportability. What do we do when there is no information one way or the other?
For cases diagnosed prior to 1/1/2010:Without further information, the term "myelodysplasia" alone is not reportable. If a more definitive diagnosis is made later, the case may become reportable.
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.
Ambiguous Terminology: Why was 60 days chosen for ambiguous terminology?
The Histology Task Force approved a 60 day time frame for ambiguous terminology.
The majority of cases are first identified by ambiguous terminology; for example, a patient has a mammogram that shows a lesion suspicious for cancer. That first indication of cancer prompts a work-up to either confirm or rule-out the cancer diagnosis.
The data item "Ambiguous terminology" is not intended to capture information on this routine method of detecting and diagnosing cancer. The 60 day time frame should keep these cases out of the ambiguous terminology data item.
The data item is intended to identify those cases where the cancer diagnosis is NOT confirmed during the work-up, but the case is still entered into the database. For example a patient who has a TRUS because of elevated PSA. The pathology from the TRUS says "Suspicious for adenocarcinoma of the prostate." The physician only documents that the patient is to return in 6 months for another PSA and TRUS. The registrar would enter this case into the data base because the word "suspicious" is on the ambiguous terminology list.
Histology--Corpus uteri: Because coding a pathology final diagnosis of "serous carcinoma" for an endometrial primary to 8441/3 triggers the site/histology error in the SEER Edits, should histology be coded to 8010/3 [Carcinoma, NOS] instead?
Assign histology code 8441 [serous carcinoma] and override the edit. Endometrium with serous carcinoma is NOT one of the "impossible" site / histology combinations.
Multiple Primaries/Histology--Lymphoma/Leukemia: How many primaries and what histologies are coded when a path diagnosis for a cervical/neck mass demonstrates classical Hodgkin's lymphoma on a background of chronic lymphocytic leukemia?
For cases diagnosed prior to 1/1/2010:Hodgkin disease and chronic lymphocytic leukemia are separate primaries according to our current instructions. Abstract and code them separately.
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.
MP/H Rules/Multiple Primaries--Lung: How many primaries should be reported when an "adenocarcinoma" is discovered in one of several new nodules at the scar in a lung and it is less than a year after a wedge resection for a diagnosis of "bronchioalveolar adenocarcinoma" in the same lung? See Discussion.
In March 2006 patient diagnosed with bronchioalveolar adenocarcinoma [8250/3] and had wedge resection. In November 2006 a CT chest shows nodules at the scar suspicious for recurrence. In January, 2007, there was a biopsy of one of the nodules showing adenocarcinoma [8140/3].
Is this part of the original disease process diagnosed in March 2006 or should it be abstracted as a new primary based on 2007 MP/H rules (histology is different at the first 3 digits)?
For cases diagnosed 2007 or later:
Try to obtain more information/clarification on the 2007 diagnosis -- for example, is it metastasis?
Based only on the information provided for this case, the 2007 diagnosis is a separate primary.
Use the 2007 MP/H rules to assess the 2007 diagnosis. Begin with rule M3 in the multiple tumors section. Stop at rule M11, multiple primaries.
MP/H Rules--Ovary: Rule M7 states bilateral epithelial tumors (8000-8799) are reportable as a single primary. Are bilateral germ cell tumors of the ovary (e.g., dysgerminoma (9060/3)) that occur simultaneously now reported as two primaries?
For cases diagnosed 2007 or later, rule M7 applies to ovarian epithelial tumors with ICD-O-3 histology codes between 8000 and 8799. Rule M7 does not apply to dysgerminoma which is coded to 9060. Go on to the next rule, M8 and abstract as multiple primaries, left and right.
MP/H Rules/Histology--Colon: How is histology coded when the final pathology diagnosis is "adenocarcinoma with extensive mucinous features" and the percent of mucinous features is not stated?
Code 8140 using rule H6. Rule H6 applies because the percent of mucinous is not specified.
Multiplicity Counter--Prostate: How is multiplicity counter to be coded for a clinically inapparent prostate cancer for which sextant needle biopsy cores on left and right sides are positive for adenocarcinoma? See Discussion.
Prostate cancer typically presents as multifocal diffuse disease. The coding exercise in the MPH rules presentations coded prostate cancer as one tumor.
Reference: SEER Training Web Casts - Other Sites Rules Practicum
Code the number of tumors present if known. This information can be taken from any part of the record, including imaging and prostatectomy. If the only information available is "diffuse," or "multifocal," assign code 99. Do not assume there are multiple tumors just beacause there are multiple biopsies. When there is no information about the number of tumors, code Multiplicity Counter to 99 and Type of Multiple Tumors to 99.
MP/H Rules/Histology--Prostate: If a patient is stated to have prostate "cancer" but a pathology report is not available nor is a specific histology stated in the medical record, can this histology be coded to 8140 [adenocarcinoma] instead of 8000/3 [cancer] because the vast majority of prostate cancers are adenocarcinomas?
For cases diagnosed 2007 and later, the correct histology code is 8000/3 [cancer]. The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Other Sites Histology rules because no specific rules have been developed for prostate primaries.
To determine the histology, start at the SINGLE TUMOR: INVASIVE ONLY module, rule H8. The rules are intended to be reviewed in consecutive order within a module. Code the histology documented by the physician when there is no pathology/cytology specimen or the pathology/cytology report is not available. Code the histology as 8000/3 [cancer] because that is the only available information. In the absence of a pathology report or any other histologic confirmation, code the histology based on the information available.
