Priorities/CS Extension--Lung: In the absence of a physician TNM, is there a hierarchy associated with coding extension when multiple imaging studies demonstrate different degrees of extension? See Discussion.
CT of the lung showing primary lesion and other nodules in another lobe or contralateral lung, subpleural nodules, etc. The PET scan did not show activity for the other nodules. What is our "hierarchy" for imaging studies when there is no physician staging?
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.
There is no hierarchy among the various imaging studies. Assign CS extension based on the report documenting the greatest extension.
Priorities/CS Tumor Size--Breast: What is the priority order used in coding tumor size for this site when there is a larger 2 cm lesion noted on the PET scan and smaller sizes described in the pathology report as two malignant masses one measuring 0.8 cm and the second measuring 1.0 cm per the GROSS?
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.Code CS Tumor Size as 1.0 cm. The pathology report is the highest priority source for coding tumor size. When multiple tumors are present, code the size of the largest tumor.
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.
CS Eval--Ovary: How is CS Mets Eval coded when the patient has positive pleural effusion confirmed by cytology?
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.Code CS Mets Eval for the example above 3 [path exam of metastatic tissue] assuming there has been no pre-treatment. Positive cytology is required for confirmation of pleural effusion for an ovarian primary.
Date Therapy Initiated/Reason no treatment--Lymphoma: Is the date of the lymph node biopsy used as the date of treatment if the lymph node biopsy is the first treatment or the only treatment performed? Is the reason for no surgery coded to 0 [Surgery of the primary site was performed]?
For cases diagnosed prior to January 1, 2008, enter the date of the lymph node biopsy (excisional biopsy or biopsy NOS) as the Date Therapy Initiated for a lymphoma when the biopsy is the first or only therapy performed.
Code Reason for No Surgery of Primary Site as 0 [Surgery of the primary site was performed] and the biopsy of a lymph node is coded to 25 in Surgery to Primary Site.
Do not code a fine needle aspiration or core needle biopsy in Surgery of Primary Site.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Breast: How are the number of primaries, histologies and CS extension fields coded for breast tissue that contains separate areas of invasive ductal carcinoma, intraductal carcinoma and Paget disease? See Discussion.
Excisional biopsy of a breast mass: 1.0 cm tumor that was infiltrating ductal carcinoma, high grade, with an associated intraductal component with comedonecrosis.
Pathology report for the mastectomy three weeks later: no residual tumor was found near the original biopsy site. In another portion of the same breast was found high-grade intraductal carcinoma involving the nipple ducts, with Paget Disease of the nipple. (No size was given for this.)
For tumors diagnosed prior to 2007:
This is a single primary. According to Exception 3 of Multiple Primary Rule 6 for multiple tumors, combinations of Paget disease and ductal carcinoma are a single primary. The histology code for this case is 8541 [Paget disease and infiltrating duct carcinoma]. Assign CS extension code 10 [confined to breast tissue] based on the information above.
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.
CS Lymph Nodes--Breast: Must there be a statement of "moveable" present to code 25 in this field and if a lymph node is not stated to be "fixed" is it presumed to be moveable? Please provide an example in your answer of when to use code 25.
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.
The word "movable" does not have to be used to assign code 25. A "movable" lymph node is an involved lymph node not described as fixed or matted. The general rule is to code the lesser or lower category, which would be the case if neither movability nor fixation is mentioned. See page C-471 of the 2004 SEER Manual.
Code 25 Example: Involved lymph nodes per lymph node dissection. No mention of fixation or matting. Size of largest met within a lymph node is 4mm.
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.
CS Lymph Nodes/Scope of Regional Lymph Node Surgery--Prostate: When prostate cancer is an incidental finding at cystoprostatectomy for bladder cancer, is the pelvic lymph node dissection coded for the prostate as well as the bladder?
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.
Yes, the pelvic lymph node dissection is coded as regional lymph node surgery for both primaries and the nodes are counted in collaborative staging for both primaries. The examination of the pelvic lymph nodes is relevant to both the bladder and the prostatic primaries.
