20031202 | Surgery of Primary Site--Head & Neck: How is this field coded for a surgery titled "Parotidectomy with facial nerve dissection"? See Description. | If the operative report is not titled "total parotidectomy," can we assume that less than total parotidectomy was done? Can we assume that "facial nerve dissection" and "facial nerve monitoring" are other ways of stating "facial nerve spared"? | Use the best information available to determine whether or not all of the parotid has been removed. It is important to read the entire operative report and review the content of the pathology report. The Op report will usually include wording about how much was removed, and this can be confirmed by the path report. Do not make assumptions about the extent of the surgery based solely on the title used on the operative report.
For cases diagnosed 1998-2003: Code 30 [less than total parotidectomy] can be used when the parotid is not totally removed, but the exact type of partial parotidectomy cannot be determined. "Facial nerve monitoring" and "Facial nerve dissection" are synonymous with "facial nerve sparing." |

20031156 | Histology (Pre-2007)--Ovary: Should the histology "endometroid adenocarcinoma arising in a serous fibroadenoma" be coded to 8380 [Endometroid adenocarcinoma, NOS] or 9014 [Malignant serous fibroadenoma]? | For tumors diagnosed prior to 2007:
The best code is 8381/3 [Endometroid adenofibroma, malignant]. According to our pathologist consultant: "Serous 'fibroadenoma' is not exactly standard terminology. I would guess the pathologist is looking at an adenofibroma with more fibro and less adeno and thus has changed the terminology around. The combination of the benign serous and malignant edometrioid is also a bit unusual. Each of the proposed codes is defendable, but I prefer endometrioid adenofibroma, 8381/3, because it puts the tumor in the adenofibroma category (less common) yet still identifies the malignant element (endometrioid), even though it does lose the serous. But anyone wanting to look at malignant adenofibromas would find the case, and we would carry it under the appropriate malignant component."
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. |

20031089 | Primary Site/Histology (Pre-2007)--Bone: How are these fields coded for a squamous cell carcinoma in bone? See Description. | The consult path report says "I believe that there is definitely high grade malignant tumor in this amputation specimen, and that this tumor represents an invasive squamous cell carcinoma, which is extending into the bone and permeating in between the bone trabeculae. ... The fact that squamous cell carcinoma can arise from the sinuses of chronic osteomyelitis is well recognized." | For tumors diagnosed prior to 2007:
Based on the information provided, code the primary site as C40._ or C41._ [bone] because the tumor originated in the sinuses of chronic osteomyelitis. Code to the site in which the tumor arises. Override the SEER site/histology edits to allow this rare combination of bone and squamous cell 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. |

20031032 | Diagnostic Confirmation--Hematopoietic, NOS: How should diagnostic confirmation of Hematopoietic diseases be coded in the absence of positive bone marrow? See Description. | Case 1. Patient admitted 9-12-02 with diagnosis of essential thrombocythemia. Per the H&P, patient obviously has had this since January 2001. Per the clinical history: patient with elevated platelets. Path diagnosis of bone marrow biopsy done 9-20-02 showed mildly increased megakaryocytes. 10-31-02 clinical sign-out diagnosis was: essential thrombocythemia. Case 2. Patient admitted for evaluation of erythrocytosis. Assessment: Increased hematocrit only. It is most likely that patient has polycythemia vera. I think it is reasonable to initiate phlebotomy treatment. |
Code 1, Positive histology, includes diagnostic hematologic findings and peripheral blood smears when these are the basis for diagnosis. When the clinician makes a specific diagnosis and the blood work is not diagnostic, code diagnostic confirmation as 8 [Clinical diagnosis only]. The clinician is putting together all evidence, including the blood work and using his/her professional experience to diagnose the case. Case 1. The diagnosis is not based on microscopic findings. Assign code 8 [Clinical diagnosis only]. Megakaryocytes are the immature form of thrombocytes, but mildly increased megakaryocytes are not diagnostic of essential thrombocythemia. Case 2. The diagnosis is not based on microscopic findings. Assign code 8 [Clinical diagnosis only]. |

20031008 | Histology (Pre-2007)--Kidney: Is 8316/3 [Cyst associated renal cell carcinoma] the appropriate code for 1) Cystic renal cell carcinoma, 2) Renal cell carcinoma mass with cystic areas and 3) Cystic renal cell carcinoma, clear cell type? | For tumors diagnosed prior to 2007:
Yes, ICD-O-3 histology code 8316 is the correct code for the three examples above. There are two categories of cyst-associated renal cell carcinomas: Renal cell carcinoma originating in a cyst, and Cystic renal cell 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. |

20031192 | EOD-Extension--Breast: How is this field coded when the diagnosis includes both invasive and in situ disease, and the pathology report stated the tumor size may or may not include the size of the in situ portion of the tumor? See Description. | Examples:
1. Invasive ductal carcinoma well differentiated, 1.2 cm, gross tumor size, ductal carcinoma in situ.
2. Gross tumor size 3.2 x 2.5 x 2.3 cm. well differentiated to moderately differentiated invasive ductal ca, accompanying component well differentiated ductal carcinoma in situ, solid, cribiform. |
For cases diagnosed 1998-2003: Use extension codes 16, 26, or 36 depending on extent of involvement. These codes indicate that invasive and in situ components are present, the size of the entire tumor is coded in Tumor Size, the size of the invasive component is not stated, and the proportions of in situ and invasive are not known. Both examples above measure the entire tumor including invasive and in situ components. Assign extension code 16, unless there is evidence of further involvement. |

20031158 | Multiple Primaries (Pre-2007)--Trachea/Lung: Would synchronous lesions, of the same histology, diagnosed in the right upper lobe of the lung and trachea be a single primary when the physician feels they are two separate primaries? |
For tumors diagnosed prior to 2007: According to SEER rules, abstract as one primary because although these sites have separate topography codes in ICD-O-3, they were coded to the same three-digit topography code in the first edition of ICD-O (SEER Program Code Manual, 3rd Edition, page 8, Exception B). Simultaneous lesions of the same histology in trachea and lung are one primary. Code the primary site to C399 [Ill-defined sites within respiratory system]. 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. |

20031144 | Histology (Pre-2007)--Breast: What code is used to represent the histology "Ductal carcinoma in situ; 6 mm focus of invasion is a pure mucinous carcinoma that appears to have arisen in the background of encysted papillary carcinoma." | Code to mucinous (8480) since that is the only clearly invasive component of this diagnosis. According to our pathologist consultant, "Encysted papillary carcinoma is the same thing as intracystic papillry carcinoma, which I think of as an intraductal papillary carcinoma which has greatly expanded the duct to form a cyst-like structure. It generally behaves in an in-situ rather than an invasive fashion. The only clearly invasive component is the mucinous carcinoma, which is what I would code." |

20031115 | EOD-Lymph Nodes/EOD-Extension: Does extracapsular lymph node extension into adjacent tissue or organs affect EOD coding? See Description. | For a lung primary a PET scan showed marked uptake in the right hilum consistent with metastatic disease. A radical pneumonectomy was performed and the operative findings showed that the pulmonary artery was involved with a mass. Pathology: Small cell carcinoma in the lung parenchyma. The distal bronchi showed obstructive pneumonitis. There were mets found on 02/05 on the hilar lymph nodes and 00/02 peribronchial nodes. The mets in the hilar nodes extended beyond the lymph node capsule into the pulmonary artery. |
For cases diagnosed 1998-2003: Extracapsular lymph node extension does not affect the extent of disease. Code the extent of regional lymph node involvement in EOD lymph nodes. | 2003 |

20031100 | Date of diagnosis: Can a positive VMA:HVA test be used as a date of diagnosis for neuroblastoma? See Description. |
Rubin's Clinical Oncology states: Both the catecholamines and their metabolites are used as markers for neuroblastoma, with vanillylmandelic acid (VMA) and homovanillic acid (HVA) being the most commonly used. While their absolute values are not of prognostic significance, a higher VMA:HVA ratio suggests a better prognosis for patients with disseminated disease. |
Updated answer July 2024 No. Do not code the neuroblastoma diagnosis date from only the date of an elevated urine catecholamine test (VMA or HVA). Neuroblastoma diagnosis should be made on the basis of tissue biopsy or bone marrow aspiration along with elevated urinary catecholamines. Elevated urinary catecholamines alone are not diagnostic of neuroblastoma. |
