EOD-Extension--Bladder: Both papillary transitional cell ca in situ and sessile (flat) transitional cell ca in situ are diagnosed simultaneously in the bladder. We code the higher histology (8130/2). For extension, do we use the code that corresponds to the histology (01), or to the higher extension code (06)?
For cases diagnosed between 1998-2003:
Code the EOD-Extension field to 06 [sessile (flat) (solid) carcinoma in situ], the higher extension code.
Reportability/Ambiguous Terminology/Date of Diagnosis: If a "suspicious" cytology is reportable only when a later positive biopsy or a physician's clinical impression of cancer supports the cytology findings, is the Date of Diagnosis field coded to the later confirmation date rather than to the date of the suspicious cytology? Is a suspicious "biopsy" handled the same way?
Cytology reported as "suspicious" is not reportable. If the physician confirms the suspicious cytology by making a clinical diagnosis of malignancy, the Date of Diagnosis field is coded to the date of the clinical diagnosis, which may or may not be same date the cytology was performed.
Without supporting clinical documentation, the case will remain non-reportable and will not be submitted to SEER. The supporting documentation can be a physician's statement that the patient has cancer, a scan or procedure that identifies cancer, or a positive biopsy.
Suspicious "biopsies" are reportable according to SEER's list of ambiguous terms. Suspicious "cytologies" without supporting clinical statements are not.
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.
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.
Multiple Primaries (Pre-2007)--Bladder: Should an invasive malignancy following an in situ malignancy by more than two months be a new primary? Why? See discussion.
Example: An in situ bladder case was diagnosed and treated. Three months later another TURB diagnosed an invasive bladder carcinoma. Is the invasive case reportable to SEER as a new primary?
For tumors diagnosed prior to 2007:
Yes. These are two primaries.
In situ cancers are not included in SEER incidence rates. Incidence rates must correlate with mortality rates.
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.
Reportability--Hematopoietic, NOS: Is the term "plasma cell dyscrasia" a synonym for multiple myeloma?
For cases diagnosed prior to 1/1/2010:
Plasma cell dyscrasia, NOS, is nonreportable. It is not a synonym for multiple myeloma. Plasma cell dyscrasia represents a broad spectrum of disease characterized by plasma cell proliferation that appears inappropriate or uncontrolled. Multiple myeloma is one disease type that falls into that classification. However, there are several other malignant and benign diseases also classified as such because of their immunoglobulin abnormalities. Reportability to SEER regarding a disease classified as a plasma cell dyscrasia is dependent on identifying the specific cell type associated with the disease in the ICD-O-3.
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-Extension--Cervix: How do you code tumor extension described as "the in situ lesion extends from the cervix to the mucosa of the vagina"? See discussion.
Example: Cone biopsy of cervix and vaginal vault both show ca in situ. The op report stated: "lesion extending from the left lateral portion of the cervix onto the left lateral portion of the vagina." The pathologist stated it "appeared to be an in situ lesion extending from the cervix to the mucosa of the vagina."
For cases diagnosed 1998-2003:
Code the Primary Site to C53.9 [Cervix uteri] and the EOD-Extension filed to 00 [in situ]. In situ is a measurement of invasion. Extension of the cervical in situ carcinoma via the mucosa to the vagina does not affect the EOD extension code.
EOD-Extension--Pancreas: How do you code extension when a mass is described on exploratory laparotomy as compressing the duodenum, arising in the head of the pancreas, "extending around" the superior mesenteric vein and artery, and "encasing" the portahepatis?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 40 [extension to peripancreatic tissue, NOS]. Neither of the terms "extending around" nor "encasing" are interpreted as involvement with tumor by SEER.
First Course Treatment: What code is used to represent each treatment modality field when there is no indication that a particular modality of treatment was recommended or started?
Code the individual treatment fields to 0 or 00 [None] when the modality is not addressed in the treatment plan (or when a treatment plan is lacking) and there is no indication that a particular modality of treatment was recommended or started.
