20160011 | Reportability--Stomach: Are microcarcinoid tumors reportable? See discussion. |
SINQ 20081076 states carcinoid tumorlets of the lung are not reportable and are defined as being less than 5 mm in diameter and benign. Per the WHO Classification of Digestive Tumours, microcarcinoid tumors are precursor lesions/nodules measuring greater than 0.5 mm, but less than 5 mm (0.5 cm). Is the term microcarcinoid tumor equivalent to carcinoid tumorlet, and therefore not reportable? Or is a microcarcinoid tumor a reportable type of neuroendocrine tumor (NET)? |
Microcarcinoid and carcinoid tumors are reportable. The ICD-O-3 histology code is 8240/3. Microcarcinoid is a designation for neuroendocrine tumors of the stomach when they are less than 0.5 cm. in size. Neuroendocrine tumors of the stomach are designated carcinoid when they are 0.5 cm or larger.
The term microcarcinoid tumor is not equivalent to carcinoid tumorlet. |

20160017 | Surgery of Primary Site--Melanoma: Please further explain the SEER Note under Melanoma surgery codes 30-36 for these two examples. Are both examples coded 31? 1. Shave bx: +melanoma in situ, +microscopic margins Wide excision: no residual melanoma in situ 2. Shave bx: melanoma, +microscopic margin Wide excision: Melanoma, margins negative (margin status negative but distance not stated) |
Revised answer: Assign surgery code 30 for both examples based on the SEER Note on the top of page 2 in the Surgery of Primary Site Codes for Skin: If it is stated to be a wide excision or reexcision, but the margins are unknown, code to 30. |

20160051 | Diagnostic confirmation: When a CT guided Fine Needle Aspiration is performed and the pathology report indicates smears and cell block were prepared, if the diagnosis is positive for cancer, can you code diagnostic confirmation as 2 (positive cytology) because of the cell block? |
Yes, assign diagnostic confirmation code 2 for diagnosis based on smears and cell block from CT guided FNA. This reply pertains to solid tumors. |

20160065 | MP/H Rules/Histology--Lung: What histology code and MP/H Rule applies to the Histologic Type described as adenocarcinoma, mixed invasive mucinous and non-mucinous which involves multiple lung tumors present in a single lobe? See Discussion. |
The patient had a lower lobectomy with final diagnosis of adenocarcinoma with the following features: Tumor Focality: Multiple separate tumor nodules in same lobe; Tumor Size: 2.6 cm, 0.7 cm, 0.3 cm and 0.1 cm in greatest dimension; Histologic Type: Adenocarcinoma, mixed invasive mucinous and non-mucinous adenocarcinoma; Histologic Grade: Moderately differentiated. |
Assign histology code 8254/3.
The 2007 MP/H Lung rules do not include coding guidelines for mixed mucinous and non-mucinous tumors. Lung Table 1 (in the Terms and Definitions, pages 37-38, http://seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf ) is very specific about which histologies can be coded to mixed adenocarcinoma (8255/3). Mucinous is not included per the note at the end of Table 1. Per WHO 3rd and 4th Ed Tumors of the Lung, mixed mucinous and non-mucinous tumors of the lung are classified as 8254/3. Mixed invasive mucinous and non-mucinous adenocarcinoma is a synonym for BAC, mucinous and non-mucinous. |

20160058 | First course treatment--Heme & Lymphoid Neoplasms: Are blood thinners, e.g., warfarin, coded as treatment in the Other Therapy data item for polycythemia vera and myelodysplastic syndrome? See Discussion. |
Under the hematopoietic data base, treatment for polycythemia vera shows chemotherapy, immunotherapy, and phlebotomy. Essential thrombocytopenia shows blood thinners, anti-clotting medications, aspirin, chemotherapy, immunotherapy, and other therapy (Anagrelide) (for essential thrombocythemia only) and watchful waiting (for asymptomatic patients). Myelodysplastic syndrome shows bone marrow transplant, chemotherapy, immunotherapy, and stem cell transplant.
SEER*RX under warfarin says: Per the 2012 Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual (page 10), blood thinners and/or anti-clotting agents are to be coded as treatment (Other Therapy) for the following histologies: 9740/4 Mast cell sarcoma 9741/3 Systemic mastocytosis 9742/3 Mast cell leukemia 9875/3 Chronic myelogenous leukemia BCR/ABL 1 positive 9950/3 Polycythemia vera 9961/3 Primary myelofibrosis 9962/3 Essential thrombocythemia 9963/3 Chronic neutrophilic leukemia 9975/3 Myelodysplastic/myeloproliferative neoplasm, unclassifiable. |
Based on information from the National Cancer Institute and the Food and Drug Administration, aspirin and/or other blood thinners are not valid treatment for polycythemia vera and myelodysplastic syndrome. These drugs are often given to relieve symptoms of the disease such as bone pain or side-effects of standard treatments including blood clots. The treatment information found on page 22 (2015 Hematopoietic & Lymphoid Neoplasms coding manual) will be updated and ICD-O-3 codes 9950/3 and 9975/3 will be removed from the list. SEER*RX has been updated to reflect this change. |

20160024 | Reportability--Melanoma: Please explain how a CTR is to interpret the guideline in the MP/H rules (Cutaneous Melanoma): Evolving melanoma (borderline evolving melanoma): Evolving melanoma are tumors of uncertain biologic behavior. Histological changes of borderline evolving melanoma are too subtle for a definitive diagnosis of melanoma in situ. Is this to mean that evolving melanoma in situ is not reportable? Or should we follow the guidelines in SEER Question 20130022 that states the reportability terms for melanoma and melanoma in situ. |
Follow the guidelines in SINQ 20130022 for now. When the MP/H rules are revised, new instructions will be implemented.
See also SINQ 200120078 and 20110069. |

20160029 | Radiation Therapy--Breast: Are iodine 125 (I-125) seed implants for breast cancer coded as brachytherapy or as a localization technique similar to wire localization? See Discussion. |
We are seeing many I-125 seed implants for breast cancer. Many of my associates are coding them as brachytherapy. I think they are the newest of the localization technique like wire localization but with greater accuracy. Most are done the same day as the surgery so brachytherapy does not make sense. Which is correct? |
I-125 seeds could be used for brachytherapy for breast cancer or as a localization technique for nonpalpable breast tumors. If the seeds were in place a short time and removed as part of a breast surgical procedure, they were likely used for tumor localization. Radioactive seed localization (RSL) is thought to be more precise than the wire implantation technique for localizing lesions. |

20160016 | MP/H Rules/Histology--Bladder: Can the histology for a high grade urothelial carcinoma described as having "extensive sarcomatoid dedifferentiation" be coded to sarcomatoid transitional cell carcinoma (8122/3)? Example; TURBT, Final Diagnosis - Urothelial carcinoma, high grade. Type/grade comment: Extensive sarcomatoid dedifferentiation is present (40-50% of tumor volume). |
Code high grade urothelial carcinoma described as having "extensive sarcomatoid dedifferentiation" to sarcomatoid transitional cell carcinoma (8122/3). |

20160007 | Surgery of Primary Site--Breast: If the diagnosis is a single primary involving both breasts, do we code 41 Surgery Primary site with 1 in Surgery Other site, or code 76 Surgery Primary site with 0 in Surgery Other site? See discussion. |
In Appendix C- Breast (SEER Manual 2015) it states under the codes for TOTAL MASTECTOMY (Codes 40-49, 75): For single primaries only, code removal of involved contralateral breast under the data item Surgical Procedure/Other Site (NAACCR Item # 1294). [SEER Note: Example of single primary with removal of involved contralateral breast--Inflammatory carcinoma involving both breasts. Bilateral simple mastectomies. Code Surgery of Primary Site 41 and code Surgical Procedure of Other Site 1.] HOWEVER, underneath that it states code 76 is used for: 76 Bilateral mastectomy for a single tumor involving both breasts, as for bilateral inflammatory carcinoma. So |
Assign code 41 with 1 in surgery other site for simple mastectomy. Assign code 76 with 0 in surgery other site for a more extensive mastectomy. |

20160009 | MP/H Rules/Histology--Appendix: What is the histology for an appendix resection diagnosis of "Malignant neoplasm of the appendix with the following features: Histologic type: Adenocarcinoma ex goblet cell carcinoid with mucin production (adenocarcinoma arising from goblet cell carcinoid)"? Is this histology best coded to a mixed adenocarcinoma/carcinoid tumor (8244/3)? |
Code histology to combined carcinoid and adenocarcinoma (8244/3). The tumor is a mix of adenocarcinoma and carcinoid. |
