EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined/Surgical Procedure of Other Site--Kaposi Sarcoma: How do you code these fields for a groin mass excision containing 4 lymph nodes for a Kaposi sarcoma case that presented with multiple skin lesions?
Code the EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined fields to 99 99 for Kaposi cases that present systemically and for those that present in more than one site (which includes cases with more than one skin subsite involved at diagnosis). There are no "regional" lymph nodes for such cases. This represents a majority of currently diagnosed Kaposi cases. However, for localized Kaposi cases, you can count the number of regional lymph nodes positive and examined if the primary site selected has a regional lymph node chain(s) associated with it (e.g., soft palate, hard palate, or a skin subsite).
For cases diagnosed 1/1/2003 and after: Code the groin mass excision in the Surgical Procedure of Other Site field to 1 [Non-primary surgical procedure performed; Non-primary surgical resection to other site(s), unknown if whether the site(s) is regional or distant].
EOD-Extension/EOD-Lymph Nodes--Bladder: Are "perivesical nodules" coded in the EOD-Lymph Nodes field or are they discontinuous extension and coded in the EOD-Extension field?
For cases diagnosed 1998-2003:
Code "perivesical nodules" in the EOD-Lymph Nodes field as involvement of regional lymph nodes. Each gross nodule of metastatic carcinoma in the fat surrounding an organ is counted as one positive regional lymph node.
EOD-Extension--Small Intestine: How do we interpret a pathology description of "extending through serosa and forming masses in the periserosal tissue" for a jejunum primary?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 55 [Invasion of/through serosa and adjacent connective tissue]. The description states the tumor extended through the serosa into periserosal tissue. The periserosal tissue in this case refers to adjacent connective tissue lying exterior to the intestinal wall and not the (sub)serosal tissue that lies exterior to the muscularis but inferior to the serosa. Analyze each case individually since pathologists are not consistent when using the above terminology.
Surgery of Primary Site--Lung: What code is used to represent "photodynamic therapy" (PDT) for lung primaries? See Discussion.
PDT is not listed in the Surgery to Primary Site field codes for lung.
For cases diagnosed 2003 and later, code the Surgery of Primary Site field to 19 [Local destruction or excision, NOS] for lung primaries. Photodynamic therapy is a surgical procedure that results in the local destruction of tumor.
Multiple Primaries (Pre-2007)--Breast: When a breast cancer is treated with less than a total mastectomy and more than 2 months later a tumor of the same histology is diagnosed in the same breast with no statement of "recurrence," is this a new primary?
For tumors diagnosed prior to 2007:
Count as 2 primaries when a subsequent malignant breast tumor is diagnosed more than 2 months later unless stated to be a recurrence. For cases diagnosed after 1/1/94, an in situ followed by an invasive breast cancer is counted as two primaries even if stated to be a recurrence.
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.
EOD-Extension--Lymphoma: What code is used to represent a non-Hodgkin lymphoma presenting with involvement of an extralymphatic organ and lymph nodes on the opposite side of the diaphragm?
For cases diagnosed 1998-2003: Code the EOD-Extension field to 31 [30 + localized involvement of an extralymphatic organ or site; Stage III E].
Surgery of Primary Site/Reconstruction-First Course--Breast: If the plan is to "reconstruct" the breast 6 months after an ipsilateral modified radical mastectomy, is the time span a problem or should it be coded in the Surgery of Primary Site field because it was planned?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 55 [Modified radical mastectomy WITHOUT removal of uninvolved contralateral breast, Implant]. The time span is not a problem as long as the reconstruction was planned as first course, which is indicated by tissue expander insertion at the time of the original surgery.
Histology (Pre-2007)--Colon: What code is used to represent the histology "adenocarcinoma arising in a papillary adenomatous polyp"? See discussion.
Is "adenocarcinoma arising in a papillary adenomatous polyp" equivalent to adenocarcinoma in a villous adenoma [8261/3] or adenocarcinoma in an adenomatous polyp [8210/3]?
For tumors diagnosed prior to 2007:
Code the Histology field to 8261/3 [adenocarcinoma in a villous adenoma]. In describing colon polyps, papillary and villous are equivalent terms.
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.
Primary Site--Lymphoma: How should you code the primary site for a lymphoma that presents with involvement of an extranodal site and regional lymph nodes? See discussion.
1. Lymphoma involves the spleen and the splenic lymph nodes.
2. MALT Lymphoma involves the stomach and the gastric and iliac lymph nodes.
1. Code the Primary Site field to C42.2 [spleen].
2. Code the Primary Site field to C16._ [stomach].
When lymphoma presents in an extranodal site and in the regional lymph nodes for that extranodal site, code the Primary Site field to the extranodal site. The typical disease process is that lymphoma can spread from an extranodal organ to its regional lymph nodes. It cannot metastasize from the regional lymph node to the extranodal organ. The exception to this would be if the lymph nodes presented as one large mass that extended into the regional organ.
EOD-Size of Primary Tumor--Breast: If the patient has inflammatory carcinoma of the breast, is the tumor size coded as 998 even though we have a tumor size?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary tumor field to 998 [Diffuse; widespread; 3/4 or more of breast; inflammatory carcinoma] for all inflammatory breast carcinomas.
These cases have a worse prognosis because of the dermal lymphatic invasion. Half of the inflammatory breast carcinomas will have no palpable mass.
