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.
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).
Diagnostic Confirmation--Testis: How do you code this field when a testicular mass is confirmed to be cancer on physical exam and testicular antigen, but the orchiectomy specimen was negative and yet the final signout diagnosis on the medical record was "testicular cancer"?
Code the Diagnostic Confirmation field to 5 [Positive laboratory test/marker study] because the disease was confirmed both clinically and by a positive marker. Code 8 [Clinical diagnosis only] is used when the diagnosis is based on information other than that coded in 5, 6, or 7 [positive lab test/marker study, visualization, and radiography or other imaging techniques]. Code 8 is rarely used.
Spanish Surname or Origin: If Asians, Blacks and Whites with non-Spanish surnames are born in a Spanish country, is this field coded to Spanish or non-Spanish? See discussion.
For example, how do we code Miyako Mitsubishi with race listed as Japanese who was born in Peru or Sylvia Shapiro with race listed as White who was born in Argentina?
For both cases, code the Spanish Surname or Origin field to 0 [Non-Spanish/Non-Hispanic]. Persons with non-Spanish surnames would not be coded as being Spanish solely because they are born in a Spanish country. Do not code Spanish ethnicity based only on birthplace. Place of birth is a separate data item and it can be used in data analysis to identify this particular group of people.
Surgical Procedure of Other Site: Is the excision of a distant lymph node or a fine needle aspirate (FNA) of a distant lymph node coded as a Surgical Procedure of Other Site, even though they are performed for diagnostic purposes and not intended as treatment?
For cases diagnosed 1/1/2003 and after: Code the Surgical Procedure of Other Site field to 3 [Non-primary surgical procedure to distant lymph nodes] for an excision of a distant lymph node because it is a surgical procedure. However, if only a fine needle aspirate of a distant lymph node is done, code this field to 0 [None].
Fine needle aspirates of regional lymph nodes are the only FNA biopsies to be coded in a surgery field (Scope of Regional Lymph Node Surgery field). In addition, FNA biopsies of regional nodes are also included in the EOD-Number of Positive Regional and Examined Lymph Nodes fields.
EOD-Pathologic Extension--Prostate: Does capsular invasion (code 32) take priority over apex extension (code 34) on prostate primaries? See discussion.
On prostatectomy, adenocarcinoma involves left apex and also left mid lobe where it focally invades capsule. Do we code extension to 34 - the highest numerical code, or to 32 to capture the capsular invasion? Do codes 33 and 34 represent a subset of code 31, and would code 32 represent greater tumor involvement?
For cases diagnosed 1998-2003:
Code the EOD-Pathologic Extension field to 32 [Invasion into (but not beyond)prostatic capsule] when there is both capsular and apex invasion of the prostate.
Although numerically lower, code 32 takes precedence over codes 33 [arising in the apex] and 34 [extending to the apex]. Codes 33 and 34 are "subsets" of code 31 [Into prostatic apex/arising in prostatic apex].
Histology (Pre-2007)--Breast: What code is used to represent the histology "duct carcinoma, colloid type"? See discussion.
Do we use 8480/3 [colloid carcinoma] or 8523/3 [duct carcinoma] mixed with other types of carcinomas?
For tumors diagnosed prior to 2007:
Code the Histology field to 8480/3 [colloid carcinoma] per Rule 4. The lesion is colloid type of ductal carcinoma, not ductal carcinoma mixed with colloid carcinoma.
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-Size of Primary Tumor: How do you code tumor size for lesions described as "at least 2 cm"? See discussion.
The expression "at least 2 cm" seems to be different from "greater than 2 cm." Stating "at least" seems to indicate that if the tumor is larger than 2 cm, it is difficult to ascertain the exact tumor size. Should we accept 2 cm as the best info we have, or default to 999 because of the lack of specificity?
For cases diagnosed between 1998-2003:
Code the EOD-Size of Primary Tumor field to 020 [2 cm], using the rule "code what you know."
Reason no treatment/Surgery of Primary Site: Does the "Reason for No Cancer-Directed Therapy" field only relate to the "Surgery of Primary Site" field? If so, for what diagnosis years is that effective? Have SEER's coding guidelines changed over time? See discussion.
Whenever a surgical procedure is performed that results in a non 0 or 9 code in any one of the Surgery fields, should the Reason for No Site-Specific Surgery field be coded to 0 [Cancer-directed surgery performed]?
For cases diagnosed 2003 and forward: The field "Reason for No Surgery of Primary Site" applies only to surgery of primary site. This is a change from the pre-2003 instructions.
Grade, Differentiation--All Sites: Should we take the grade from a TNM staging form over a grade stated in a pathology report when the grade mentioned on the TNM staging form is a higher grade (e.g., Pathology report diagnosis is moderately differentiated adenocarcinoma, Gleason's 3+3=6, but the physician checked "poorly differentiated" on the TNM form)?
Code the Grade, Differentiation field to 2 [moderatley differentiated]. Code from the pathology report over the TNM staging form. If you do not have access to the path report, use the grade from the TNM form.
