20021003 | Multiple Primaries (Pre-2007): Whenever two hollow organs are diagnosed simultaneously with the same histology, one being invasive and the other in situ, can one assume that mucosal spread has occurred and that this situation represents one primary? In the absence of a physician statement, how do you determine mucosal spread from one organ to another? | For tumors diagnosed prior to 2007:
Yes, this type of situation represents one primary. A tumor that is breaking down can be invasive in the center with in situ cancer at the margins. Occasionally the in situ margin can move into a contiguous organ with the same type of epithelium.
Physicians may describe mucosal spread in various manners. You will see the terms "intramucosal extension," "in situ component extending to," or statements of an invasive component in one organ, with adjacent/associated in situ carcinoma in a contiguous organ with the same type of epithelium. A frequent example of this process is bladder cancer extending into the prostatic urethra via mucosal spread.
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. |

20021132 | EOD-Extension: The medical record lacks a clear statement that metastatic workup was complete. A metastatic deposit is identified within 4 months of diagnosis and while the patient is undergoing first course of treatment. How do you code the EOD-Extension field? |
For cases diagnosed 1998-2003: In coding the EOD-Extension field, ignore metastasis that is discovered after the initial workup is completed regardless of the timeframe from diagnosis date until the date the metastatic deposit was discovered. The metastasis is progression of disease. Any of the following represents progression of disease. Do not code the subsequently identified metastatic involvement in the EOD: 1) The metastatic workup was complete and treatment started before the procedure was done that found the metastatic involvement. 2) A procedure, such as a scan, was negative initially and a repeat of that procedure is now positive. 3) The treatment plan is developed for a localized disease process. If you are unable to determine whether the newly discovered metastasis represents progression or is part of the initial workup, regard the metastasis as progression. Do not code the metastasis in the EOD-Extension field. |

20021050 | EOD-Extension--Pancreas: If the tumor involvement for a case falls between two different regional extension codes, should we code to the lesser of the two codes or should we code extension as unknown? See discussion. | Example 1: CT scan description: Mass in the head of the pancreas. The duodenum is "surrounded" by tumor. Should we code extension to 40 [peripancreatic tissue extension, NOS] or 99 [unknown] because the extension code could be further than 40. It could be 44 [extension to duodenum].
Example 2: CT scan description: Mass in region of pancreatic head and "root" of superior mesenteric artery consistent with pancreatic cancer. Should we code extension to 40 [peripancreatic tissue extension, NOS] or 99 [unknown] because the extension code could be further than 40? It could be 54 [extension to major blood vessels]. |
For cases diagnosed 1998-2003:
In both examples, code the EOD-Extension field to 40 [peripancreatic tissue extension, NOS]. Choose the lowest of a known possible extension code over an unknown code. |

20021082 | Multiple Primaries (Pre-2007)/Primary site/EOD-Extension--Head & Neck: How many primaries are represented by an invasive squamous cell carcinoma of the floor of mouth with in situ squamous cell carcinoma involvement of the frenulum? |
For tumors diagnosed prior to 2007: Code the Primary Site field to C04.9 [floor of mouth]. Because the cancer did not INVADE into a neighboring site (through wall, through soft tissue), it just spread along the mucosa (in situ) to involve the frenulum, this is one primary. For cases diagnosed 1998-2003, in situ extension via mucosal spread to the frenulum is ignored for purposes of coding EOD-Extension. 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. |

20031112 | Primary Site/Histology (Pre-2007)--Unknown & ill-defined site: How are these fields coded for a markedly atypical high grade malignant neoplasm diagnosed by a fine needle aspiration of a large iliac mass, right buttock area? See Description. |
The diagnosis was made in Oct. 2002 by a CT guided fine needle aspiration of a large iliac mass, right buttock area. The cytology report says: a. positive for malignant cells, markedly atypical high grade malignant neoplasm. b. It is impossible to tell from this aspiration biopsy whether or not this represents a high grade sarcoma or a high grade carcinoma, but our consensus opinion is that this lesion is a high grade carcinoma. The combination of soft tissue topography and carcinoma morphology is Impossible by SEER edits. How should we code this? |
For tumors diagnosed prior to 2007: Code the site to C76.3 [Pelvis, NOS]. Code the histology to 8010/34 [Carcinoma, NOS, high grade]. Unless there is better information available regarding the site, assign C76.3. The information provided above does not indicate the exact site of the mass. Code the histology based on the consensus opinion stated 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. |

|
20031186 | Immunotherapy/Radiation Therapy: Is I-131 labeled immunoglobulin coded as immunotherapy or radiation therapy? | Code treatment with I-131 labeled immunoglobulin as radiotherapy. The primary action is radiotherapeutic. Radioimmunotherapy (RIT) uses antibodies to deliver the radiotherapy to the site of the tumor. | 2003 | |
|
20031051 | Histology (Pre-2007)/Sarcoma: What code is used to represent the histology "Ewing's Sarcoma/Primitive Neuroectodermal Tumor (PNET)"? See Description. | A comment on one path report states "some authors consider both Ewing's & PNET to be the same biologic entity given that they share the same translocation between chromosomes 11 & 22." The pathologists at our children's hospital agree with this statement and contend that the two should have the same histologic code. | For tumors diagnosed prior to 2007:
Code histology as 9260/3, Ewing sarcoma. Ewing sarcoma is a specific histology on the continuum of primitive neuroectodermal tumors. Code Ewing sarcoma as it is more specific than PNET, NOS.
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. |

20031206 | EOD-Extension: How is this field coded for synchronous primaries when metastatic disease is found and there is no statement to indicate which primary is the source of the metastases? See Description. | Patient was diagnosed with both esophageal and pancreatic cancer. Liver metastases were also identified. The source of the liver mets is unknown. | For cases diagnosed 1998-2003: Search the record for information about the source of the metastasis. If no such information can be found, code the metastasis to both primaries. Update the abstracts when information becomes available confirming the primary site responsible for the metastasis. Assuming the liver metastases in the example above are distant (i.e. not contiguous) code extension as 85 [Metastasis]. | 2003 |
|
20031025 | Histology (Pre-2007): Is a small cell undifferentiated carcinoma coded to 8041/34 [small cell carcinoma undifferentiated] or to 8045/34 [combination small cell AND undifferentiated carcinoma] using terms from the 2 columns in Appendix 1 of Coding Complex Morphologic Diagnoses? See discussion. | Per pathology report, diagnosis is small cell undifferentiated carcinoma in biopsies taken from the laryngeal surface of the epiglottis and left false vocal cord. | For tumors diagnosed prior to 2007:
Code histology as 8041/34 [small cell carcinoma, undifferentiated]. The diagnosis indicates that this is an undifferentiated small cell carcinoma, rather than a mixture of small cell carcinoma with undifferentiated 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. |

20031076 | EOD-Size of Primary Tumor--Prostate: Is this field coded to the size of a hypoechoic mass identified on a TRUS when there is no tumor size from the prostatectomy specimen? | For cases diagnosed 1998-2003: Ultrasound measurement of a malignancy can be used to code EOD-Size of Primary Tumor. Information on tumor size taken from imaging/radiographic techniques has low priority, just above physical examination. | 2003 |
