Histology (Pre-2007)/EOD-Lymph Nodes/SEER Summary Stage 2000--Breast: What codes are used to represent these fields for a breast case with a diagnosis of ductal carcinoma in situ and a positive regional lymph node?
For tumors diagnosed prior to 2007:
Code the Histology field to 8500/3 [Infiltrating duct carcinoma, NOS]. Code the EOD-Lymph Nodes field to 6 [Axillary/regional lymph nodes, NOS] and the SEER Summary Stage 2000 field to 3 [Ipsilateral regional lymph nodes(s) involved only].
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.
Surgery of Primary Site--Breast: What code is used to represent this field for a breast primary treated with a "bilateral mastectomy"? See discussion.
Pt diagnosed with rt breast primary opted to be treated with rt modified radical mastectomy and lt simple mastectomy. Path revealed invasive ductal carcinoma on the rt and ductal carcinoma in situ on the lt. Path reported 14 axillary lymph nodes were found in the mastectomy specimen.
There are two primaries. For cases diagnosed 1/1/2003 and after: For the rt breast, code Surgery of Primary Site to 51. The contralateral left breast malignancy is not involved with the right breast primary by either direct extension or metastasis. Codes 42 and 52 are used to capture prophylactic mastectomy of the opposite noncancerous breast. In this case, the opposite breast has cancer so these codes cannot be used. Code Scope of Regional Lymph Node Surgery to 5 and Surgical Procedure of Other Site to 0.
For the lt breast, code Surgery of Primary Site to 41, Scope of Reg LN Surgery to 0, and Surgical Procedure of Other Site to 0.
Histology--CLL/SLL: If a tissue diagnosis of "small lymphocytic lymphoma" is made six months after an initial blood diagnosis of "chronic lymphocytic leukemia" should the histology be updated from 9823/3 to 9670/3?
For cases diagnosed prior to 1/1/2010:Do not change the histology to small lymphocytic lymphoma (9670/3). The chronic lymphocytic leukemia has advanced/progressed and disseminated into other tissues from the blood during the last six months. If the patient presents with disease in the blood and/or bone marrow only, code to CLL. If a lymph node or other solid tissue is involved initially, code to SLL. For the case cited, the tissue involvement occurred six months after the initial diagnosis and the histology code is not changed to reflect the progression of disease.
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.
EOD-Size of Primary Tumor: Should the code 001 in tumor size be used for tumors described as having "focal" involvement? See discussion.
Is tumor size coded to 001 for the following examples:
Example 1: Focal adenoca in left lobe on prostatectomy.
Example 2: Multifocal ductal carcinoma of breast on mastectomy.
Example 1 and 2: There is insufficient information in the examples to determine whether EOD-Size of Primary Tumor should be coded to 001.
The instructions are that code 001 is used for a microscopic focus or foci of tumor only. That means that the tumor is small enough that it could not be seen by the naked eye, nor would it be palpable. Be careful with the term "focal" because it is most often used to describe tumor cells grouped or concentrated in one area as in example 1. There is no implication that this focus was microscopic only. Was it mentioned in the gross or macroscopic portion of the pathology report? If so, it is not coded to 001. Was it palpable? If so, it is not coded to 001.
Example 2 cites a multifocal breast cancer. Again, did the pathologist visualize the cancer (was it reported on the gross or macroscopic portion of the pathology?) If so, do not use code 001. Was the lesion palpable? If so, do not use code 001.
All Surgical Fields/Radiation Sequence with Surgery--Unknown Primaries: What codes are used to represent these fields for an unknown primary treated with a radical neck dissection followed by radiation therapy?
For unknown primaries treated with a lymph node dissection and diagnosed 1/1/2003 and after, code:
1) Surgery to Primary Site: 98 [All unknown and ill-defined disease sites, WITH or WITHOUT surgical treatment].
2) Scope of Regional Lymph Node Surgery: 9 [Unknown or not applicable].
3) Surgical Procedure of Other Site: 1 [Surgery to other site(s) or node(s), NOS; unknown if regional or distant].
4) Radiation Sequence with Surgery: 3 [Radiation after surgery]. Any planned surgical treatment is used to code radiation/surgery sequence (per CoC I&R).
Scope of Regional Lymph Node Surgery/EOD-Number of Regional Nodes Examined: What codes is used to represent these fields when the surgeon states that a "lymph node dissection" was done, but no nodes are identified in the pathology report?
For cases diagnosed 1/1/2003 and after: Code the Scope of Regional Lymph Node Surgery field to 3 [Number of regional lymph nodes removed unknown or not stated; regional lymph nodes removed, NOS] and code the EOD-Number of Regional Nodes Examined field to 00 [No nodes examined].
The surgery fields reflect the procedures the physician performed. The EOD fields reflect the results of those procedures.
EOD-Lymph Nodes--Breast: Are lymph nodes described as being either "keratin positive" or "keratin positive for metastasis" to be coded as involved lymph nodes?
For cases diagnosed between 1998-2003:
Lymph nodes that are only "keratin positive" would not be coded as involved lymph nodes. The pathologist uses this expression to mean that the nodes stained positive for keratin that does not mean they are also involved with cancer.
However, if the pathologist uses these stains to make a definitive diagnosis of metastatic carcinoma (i.e., uses the expression "keratin positive for metastasis"), then code the nodes as involved.
Histology (Pre-2007)--Prostate: What code is used to represent the histology "adenocarcinoma, cribriform type"?
For tumors diagnosed prior to 2007:
Code the Histology field to 8201/3 [cribriform carcinoma]. The word "type" is a term that indicates majority of the tumor. The term "cribriform" would be a term used to determine the histology code.
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.
Histology (Pre-2007): What code is used to represent the histology "adenocarcinoma, undifferentiated, with sarcomatoid features"? See discussion.
Is the case more accurately coded with histology of adenosarcoma [8933/34] or adenocarcinoma, undifferentiated [8140/34]? Should "sarcomatoid" be interpreted as sarcoma?
For tumors diagnosed prior to 2007:
Code the Histology field to 8140/34 [adenocarcinoma, undifferentiated]. Sarcomatoid means sarcoma-like and should not be used in coding histology.
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.
