CS Lymph Nodes--Breast: Which category has priority when both apply, "Regional lymph nodes, NOS" or "Stated as N_, NOS"? See Discussion.
Example: When there is a clinical diagnosis of axillary lymph node metastasis for a breast primary on a physical exam "Enlarged axillary lymph nodes suspicious for metastatic involvement", as well as a clinical N1 designation, do we code as 60 [Axillary LNS, NOS] or 26 [Stated as N1, NOS]?
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.For the example provided, assign code 25 [Movable axillary lymph node(s)...] for "Enlarged axillary lymph nodes suspicious for metastatic involvement." Code 60 [Axillary/regional lymph node(s), NOS] is the least specific and would not be used in this case because axillary nodes are defined in code 25. Code 26 is for cases in which "N1, NOS" documented by the physician is the only information available.
Chemotherapy/Radiation Therapy--Lymphoma: How is treatment coded when Rituxan is given in combination with the monoclonal antibody Zevalin conjugated to 90-Yttrium or the monoclonal antibody Bexxar conjugated to 131-Iodine in the treatment of NHL?
Code Rituxan as chemotherapy. Code 90-Yttrium as radioisotope. Code 131-Iodine as radioisotope when given with Rituxan as treatment for lymphoma.
Zevalin is a monoclonal antibody conjugated to Yttrium 90. Bexxar is a monoclonal antibody conjugated to Iodine 131. In both drugs, the monoclonal antibody is only the delivery agent for the radioisotope. Both drugs should be coded as radioisotopes. The one-two-three punch of Rituxan and zevalin followed by Rituxan and Bexxar should be coded as chemotherapy plus radioisotopes. Zevalin is also used by itself for people who have not responded to Rituxan.
Reportability/Behavior--Colon: Is a final diagnosis of "mucosal carcinoid" of the colon reportable with a behavior code 2 [in situ] or 3 [invasive] if the microscopic description states that a "malignancy is not appreciated"? See Discussion.
2002 carcinoid case. Path final diagnosis: sigmoid colon polyp, bx-- sm mucosal carcinoid (1.5mm) w/crush artifact in a colonic polyp showing assoc inflammatory and hyperplastic changes. Micro: due to prominent crush artifact, histologic detail is compromised; however, significant atypia or malignancy is not appreciated.
Our state registry requests that this case be abstracted using the histology code 8240/3 because it is a mucosal carcinoid.
AJCC states TIS as being confined w/i basement membrane w/no extension through muscularis mucosae into submucosa. SEER-EOD codes as invasive: mucosa, lamina propria and muscularis mucosae. Our pathologist goes along with AJCC while we are having to code with SEER rules.
1) Assign /3 to mucosal carcinoid, unless stated to be in situ in the final diagnosis. ICD-O-3 is the reference for assigning the behavior code, not AJCC, EOD or CS.
2) The ICD-O-3 code for carcinoid of the sigmoid colon is C187 8240/3. This is reportable to SEER based on the final diagnosis above. Use the histology stated in the final diagnosis.
Grade, Differentiation/Priorities: Which has priority, the differentiation or the nuclear grade for a liver biopsy histology described as "well differentiated hepatocellular carcinoma, nuclear grade 3/4"?
For most sites, differentiation has priority over the nuclear grade when both are specified (excluding breast and kidney). Assign grade code 1 [well differentiated] to the example above.
Reportability/Behavior--Thyroid: Does the term "invasion" indicate the presence of a malignant tumor? See Discussion.
Left thyroid lobectomy showed microfollicular neoplasm with evidence of minimal invasion. Micro portion of path report stated, "The capsular contour is focally distorted by a finger of the microfollicular nodule which appears to penetrate into the adjacent capsular and thyroid tissue."
We recommend that you contact the pathologist for further information. If no further information is available, do not accession this case based on the information provided. There is no definitive statement of malignancy.
If the case was sent to a consultant, there may be another opinion available. If there is information in the record, or the treating physician can be contacted, find out whether the tumor was benign or malignant and whether there was any further treatment.
According to our pathologist consultant, based only on the information above and nothing else, do not report since there is no diagnosis of malignancy.
Reportability/Behavior--Thymus: Are "lymphocyte predominant thymoma with microscopic capsule invasion" and "Polygonal epithelial cell thymoma with invasion of the lung and pericardial fat" reportable?
Please see SINQ 20110038 for the most recent information on reporting thymoma.
First Course Treatment--Unknown & ill-defined site: We have a case with an unknown primary site and the patient had chemoembolization into the hepatic artery. We don't know how to code this treatment. See Discussion.
We were told to code as surgery (10) and chemo (01). However an unknown primary automatically gets a (98) surgery code & the chemo is coded (01) but we can't code as systemic therapy. This is an edit. Chemo coded but no date of systemic therapy.
Effective for cases coded prior to the change in policy made on January 9, 2008, code chemoembolization of a metastatic site as 1 [nonprimary surgical procedure performed] in Surgical Procedure of Other Site.
Surgery of Primary Site code 98 is assigned to all cases with an unknown primary.
In the case of a liver primary, it would be coded 10 [local tumor destruction, NOS] in Surgical Procedure of Primary Site.
CS Lymph Nodes--Prostate: How is this field coded when no scan, scope or surgical evaluation of regional lymph nodes is performed for a case with localized disease in the primary site? See Discussion.
Prior to initiation of collaborative stage, SEER prostate guidelines instructed us to code lymph node involvement as negative when clinical or pathologic extension was coded 10-34 and there was no lymph node information. Is this guideline still in effect, or do we follow the collaborative stage rules which require lymph node information or, in absence of node info, usual treatment for localized disease?
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.For prostate and other "inaccessible sites" with localized disease, code the regional lymph nodes as clinically negative when not mentioned on imaging or exploratory surgery.
Histology--Leukemia: How is "T-Cell prolymphocytic leukemia, cerebriform (Sezary cell-like) variant" coded when the pathology report COMMENT states: The cerebriform (Sezary cell-like) variant accounts for about 5% of cases of T-cell prolymphocytic leukemia?
For cases diagnosed prior to 1/1/2010:
9834/3 [Prolymphocytic leukemia, T-cell type]. According to the WHO Classification of Haematopeietic and Lymphoid Tissue Tumours, cerebriform or Sezary cell-like is a variant form of T-cell prolymphocytic 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.
