MP/H Rules/Histology--Lung: How is histology coded when there is a lung biopsy compatible with non-small cell carcinoma and regional lymph node biopsies compatible with adenocarcinoma? See Discussion.
Which histology has priority when the pathology specimens reveal different histologies in the primary site and the regional lymph node? Do we assume the lung biopsy is the most representative tumor specimen because it is from the primary site and code to 8046 [non-small cell carcinoma] or should we use rule H5 and code to 8140 [adenocarcinoma, NOS] because adenocarcinoma is a more specific histology than non-small cell carcinoma?
For cases diagnosed 2007 or later, code histology based on a pathology report from the primary site whenever possible. Code histology to 8046/3 [non-small cell carcinoma] for the case example provided.
EOD-Size of Primary Tumor: Should a 2.0 cm ulcerated mass be coded to 020 or 999 for tumor size? See discussion.
With regard to tumor size, how would SEER interpret "2.0 cm ulcerated mass"? Should this be interpreted as an ulcer, or is it a gross description of the appearance of a mass and therefore acceptable to code tumor size to it?
For cases diagnosed 1998-2003:
If this ulcerated mass is pathologically confirmed to be malignant, code the EOD-Size of Primary Tumor field to 020 [2.0 cm] based on the size of this mass in the absence of a more precise tumor size description.
Ambiguous Terminology/Date of Diagnosis: How would you code the diagnosis date when the body of an imaging report uses reportable ambiguous terminology while the final impression in that same report uses non-reportable ambiguous terminology? Would you code the diagnosis date to the date of the scan or to the subsequent biopsy date that confirmed a malignancy? See Discussion.
Within the body of a mammogram report, the radiologist stated, "diffuse inflammatory tissue throughout the rt breast w/ large rt axillary lymph nodes, consistent with an inflammatory carcinoma of rt breast." His final impression, however, said "extremely suspicious rt breast w/ extremely dense breast parenchyma and adenopathy in axilla, suggesting an inflammatory carcinoma." The patient then went on to have a biopsy, which was indeed positive for cancer.
Accept the reportable ambiguous terminology from the body of the mammogram. Record the date of the mammogram as the date of diagnosis.
The guidelines on page 4 of the 2007 SEER manual addressing discrepancies within the medical record can be applied to discrepancies within one report.
The instructions are:
If one section of the medical record(s) uses a reportable term such as
apparently and another section of the medical record(s) uses a term that is not on the reportable list, accept the reportable term and accession the case.
EOD-Extension--Lung: Are "aortico-pulmonary window", "paratracheal space", and "subcarina" coded in the EOD extension field or in the EOD lymph node involvement field? See discussion.
Would a lung tumor that extends into the AP window be synonymous with extension into the mediastinum? If so, would this also apply to extension to subcarina, paratracheal space, and other such terms corresponding to areas listed in the mediastinal lymph node field under code 2?
For cases diagnosed between 1998-2003:
Extension into the aortico-pulmonary window, would be coded in the EOD-Extension field as 70 [mediastinal extension]. If the tumor extends into the paratracheal space, subcarina, or other areas listed under the code 2 in lymph nodes, code the EOD-Extension field to 70 to capture this type of involvement.
Histology--Hematopoietic, NOS: When both the path and clinical diagnoses simultaneously reflect reportable diagnoses but one is a worse form of the same disease process, which diagnosis do we code? See Description.
Would this case be coded to RAEB or AML? Bone marrow diagnosis: Hypercellular marrow with profound trilinieage dyspoietic changes. Comment: the features are consistent with RAEB. Clinical diagnosis five days later states: Myelodysplastic syndrome, early acute myelocytic leukemia (likely AML).
For cases diagnosed prior to 1/1/2010:When several diagnoses are made as part of the diagnostic process within two months, code the one with the worst prognosis.
Code the case example as acute myelocytic leukemia.
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.
