Aplastic anemia is not reportable and it is not an alternative name for refractory anemia.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
EOD-Extension--Pancreas: How do you code extension when a mass is described on exploratory laparotomy as compressing the duodenum, arising in the head of the pancreas, "extending around" the superior mesenteric vein and artery, and "encasing" the portahepatis?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 40 [extension to peripancreatic tissue, NOS]. Neither of the terms "extending around" nor "encasing" are interpreted as involvement with tumor by SEER.
Histology (Pre-2007)--Melanoma: How is histology coded if the final diagnosis is "melanoma" and only in the comment section of the pathology report is there an indication of "Type: Lentigo Maligna. Cell Type: Small Cell"?
For tumors diagnosed prior to 2007:
Code the histology as 8742 [lentigo maligna melanoma]. Code the specific histologic type, even if stated only in the comment section.
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/Grade, Differentiation: Does the term "grade 0" refer to differentiation or does its use as a modifying phrase in the final diagnosis of "grade 0 immature teratoma" impact reportability?
Regarding the term "grade 0" for an immature teratoma, determine whether the pathologist is using that term to describe the primary tumor or its implants. The term can be used to describe both situations.
An immature teratoma (IT) may have grade 0 (benign) implants. Grade 0 implants may affect the prognosis and treatment, but the primary tumor (IT) would still be malignant and therefore reportable. If grade 0 pertains to the primary tumor (as opposed to implants) it is benign, and therefore not reportable.
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.
Immunotherapy: Is immunotherapy ever palliative treatment according to any oncologists or SEER?
Any treatment that destroys or modifies cancer tissue should be recorded as the appropriate type of treatment -- chemo, immuno, etc. Even if immunotherapy is given for symptoms/palliative treatment, it is likely to kill off tumor cells.
Primary Site: How do you code the primary site when the tumor is identified in a bladder that was reconstructed using a stomach augmentation procedure and the pathology report states, "Bladder/prostate: adenocarcinoma arising within gastric mucosa, with the following features: highly infiltrative through the bladder wall"?
Code the Primary Site field to bladder [C67.9]. Code the location of the tumor as the primary site.
MP/H Rules/Multiple Primaries: When the pathology report from a FNA or other biopsy states an "in situ" carcinoma and the patient waits more than 60 days for a more definitive procedure which documents an "invasive" carcinoma, is this reported as two primaries?
For cases diagnosed 2007 or later:
No. When the invasive component is discovered as part of the work-up phase leading to treatment decisions, the case should not be abstracted as a multiple primary. In the rare instance when a patient has not been treated and is still having diagnostic work-up greater than 60 days after the malignancy is diagnosed, do not count the invasive diagnosis as a new primary.
Radiation/Chemotherapy: How do we code radiation and chemotherapy when the only statement we have is that the patient is "referred to either an oncologist or a radiation therapist"?
For cases diagnosed 1/1/2003 and after: A referral does not mean that the radiation therapy or chemotherapy was actually recommended. These cases need follow-back to see if treatment was recommended and/or administered. Some registries code these cases as 8 [Radiation recommended, unknown if administered] or 88 [Chemotherapy recommended, unknown if it was administered] and routinely review all cases with 8 or 88 codes. Upon review, the codes are updated depending on the information found. If there is no information available, the code 8 or 88 is changed to 0 or 00 [None].
Histology (Pre-2007)--Pancreas: Is a "composite mucinous adenocarcinoma and squamous cell carcinoma" coded to 8560 [adenosquamous carcinoma] or should 8480 [mucinous adenocarcinoma] be coded rather than 8070 [squamous carcinoma] because mucinous adenocarcinoma is a higher histology code than squamous carcinoma?
For tumors diagnosed prior to 2007:
Assign code 8560 [adenosquamous carcinoma]. According to our pathologist consultant, the mix of adenocarcinoma and squamous carcinoma is adenosquamous carcinoma. Adenosquamous tumors are rare, but known, representing 3-4% of pancreatic carcinomas.
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.
