20200034 | Solid Tumor Rules (2018)/Histology--Breast: How should histology be coded for 2020 breast lumpectomy final diagnosis of invasive ductal carcinoma? Summary Cancer Data and CAP Summary states: Invasive carcinoma with the following features: Histologic type: Tubular adenocarcinoma. See Discussion. |
Per the 2018 Solid Tumor Rules instructions, Final Diagnosis and Staging Summary (synoptic report) have equal coding priority. However, it is unclear which takes priority, or if this should be a combination of components, when the histologies are two different specific histologic types per Table 3 of the Breast Solid Tumor Rules Manual. |
In this case, the pathologist states two different histologies. Per the H rules, when there are different histologies, code the histology which comprises the majority of tumor. Use H16 and code histology stated to be more than 50% of tumor OR H17, code 8523 when percentage is not stated or unknown. |

20200016 | Reportability/Histology--Vulva: Is Extramammary Paget neoplasm (intraepithelial glandular neoplasm) reportable? See Discussion. |
Patient had a vulvar biopsy with final diagnosis of Extramammary Paget neoplasm (intraepithelial glandular neoplasm). No invasion identified. We are unable to contact the pathologist or physician for clarification. Although this terminology is not listed in the ICD-O-3, web search results refer to this as a possible synonym for Paget disease with associated VIN III, which is reportable. |
According to our subject matter expert, vulvar extramammary Paget neoplasm (intraepithelial glandular neoplasm) represents an in situ malignancy and should be reported. He states "The traditional terminology should be 'extramammary Paget disease' to describe an in situ adenocarcinoma arising from extramammary glands in vulvar mucosa. I am not so sure about "extramammary Paget NEOPLASM", which may include all three Pagetoid processes: the traditional Paget disease, the Pagetoid spreading of an anal adenocarcinoma and a Pagetoid spreading of an urothelial carcinoma from the urethra. Regardless, all these entities are considered at least in situ carcinomas." We recommend that you review clinical records and imaging for the clinical scenarios mentioned above. |

20200014 | Solid Tumor Rules (2018)/Histology--Brain and CNS: How are histology and primary site coded when a resection of a spine, designated intramedullary lesion, shows primary intramedullary melanocytoma? See Discussion. |
Patient has a resection labeled as: Spine, designated intramedullary lesion. The Final Diagnosis is: Melanocytic neoplasm with features most consistent with primary intramedullary melanocytoma. The Diagnosis Comment states: The overall immunophenotypic and morphologic impression is a primary central nervous system melanocytoma. The ICD-O-3 lists melanocytoma, NOS histology code as 8726/0, but does not provide a site-associated code. If the ICD-O-3 is used, the histology would be 8726/0 and the primary site presumably would be C720 since the tumor was specifically described as being intramedullary (i.e., within the spinal cord medulla). Table 6 (Solid Tumor Rules, Non-Malignant CNS Equivalent Terms and Definitions) does not list either an intramedullary melanocytoma or melanocytoma (NOS). However, Table 6 does include meningeal melanocytosis 8728/0 and meningeal melanocytoma 8728/1. If Table 6 is used and the histology is coded 8728/1, then the primary site would presumably be C701 per the ICD-O-3 site-associated listing for this histology (C709). |
Code primary site to spinal meninges (C701) and histology to meningeal melanocytoma (8728/1). According to the WHO Classification of Tumors of the Central Nervous System, 4th ed., primary melanocytic neoplasms of the central nervous system are diffuse or localized tumors that presumably arise from leptomeningeal melanocytes. Benign or intermediate grade lesions are termed melanocytomas. Meningeal melanocytoma is defined as a well-differentiated, solid, and non-infiltrative melanocytic neoplasm that arises from leptomeningeal melanocytes. Most arise in the extramedullary, intradural compartment at the cervical and thoracic spine though they can be dural-based or associated with nerve roots or spinal foramina. |

20200086 | Solid Tumor Rules (2018)/Histology--Head & Neck: Paraganglioma, NOS is reportable and malignant for cases diagnosed 1/1/2021 and later. Paraganglioma, NOS is listed in the ICD-O-3.2 Coding Table as 8680/3 without synonyms or related terms. Table 4 (ICD-O-3.2 Implementation Guidelines) lists 8693/3 Paraganglioma as a new preferred term. Is this correct? See Discussion. |
Table 4 (Changes in reportable terminology), 2021 ICD-O-3.2 Update, does confirm that the term malignant no longer needs to be used to describe a paraganglioma, but Table 4 includes the histology for extra-adrenal paraganglioma, NOS (8693/3) as the new preferred term for paraganglioma. Paraganglioma, NOS is histology code 8680/3. Which code is correct? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
The correct code for extra-adrenal paraganglioma is 8693/3. The preferred term for 8380/3 is Paraganglioma, NOS. Table 4 of the 2021 ICD-O update was based on information from WHO. Table 9 in the Head and Neck ST rules is being revised and formatted differently for ease of coding based on diagnosis year (prior to 2021 and 2021 forward). Not ALL paragangliomas will be included in Table 9. If a term and code are not provided in the rules, refer to ICD-O and updates. |

20200063 | Solid Tumor Rules (2021)/Laterality--Melanoma: Will the table called Site for Which Laterality Code Must Be Recorded be updated in the 2021 SEER Program Coding and Staging Manual as C444 is not included? The 2021 Cutaneous Melanoma Solid Tumor Rules say that C444 requires laterality; it says (new) beside it on the new Solid Tumor Rules for 2021. |
The laterality table in the 2021 SEER manual will not be updated. Please follow the 2021 Cutaneous Melanoma Solid Tumor Rules and assign a laterality for C444. |

20200005 | Multiple Primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned and what M rule applies when a patient is diagnosed with both plasmablastic lymphoma and at least one plasmacytoma? See Discussion. |
The patient was diagnosed with an EBV-positive plasmablastic lymphoma involving the left testis on radical orchiectomy in April 2019. In September 2019, a plasmacytoma was found on a right mandibular mass biopsy. Imaging at that time revealed diffuse disease involving the thoracic spine and sinus involvement. The patient then underwent a resection of the T8 spinal/epidural tumor that also proved plasmacytoma. Subsequently, the right mandibular mass and testis slides were reviewed (at an outside facility) and both were stated to be, The T8/epidural tumor pathology was not reviewed, so it is unclear if this is also assumed to be the same disease process as the right mandibular mass or still a separate, solitary plasmacytoma. Additionally, some chart notes indicate the patient has plasmablastic lymphoma with a secondary diagnosis of plasmacytoma, while other chart notes state this is stage IV plasmablastic lymphoma involving all documented sites. Although the plasmablastic lymphoma and at least the plasmacytoma of T8 have different ICD-O-3 histology codes, the physicians do seem to be treating this as a single disease process. |
Abstract multiple primaries using the Heme and Lymphoid Rule M15. The Multiple Primaries Calculator shows that the plasmablastic lymphoma (9735/3) and extraosseus plasmacytoma (9734/3) are separate primaries. We also checked with our expert pathologist who concurs as the spinal lesion was not reviewed to prove that it is plasmablastic lymphoma, therefore, the diagnosis as per pathology remains plasmacytoma. |

20200060 | First Course Treatment/Reportability: Are there situations for which a case with a class-of-case code in the 30's should be reported to the central registry? We know these are not reportable to the CoC, but should they be reported to the central registry? See Discussion. |
Example: 3/22/2017-26 year old white female seen in the emergency room with abdominal pain. Patient was diagnosed about a month ago with breast cancer. Impression: menstrual pain. In this example the patient is newly diagnosed with breast cancer, but the second hospital does not treat or diagnose the patient; pain management for a separate condition is received only. Is this patient reported due to the history of active disease? |
Work with your central registry to determine which cases they require you to report. In general, any case still undergoing first course of treatment, even if not given at your facility, should be reported to the central registry. Many central registries will appreciate knowing that the patient was seen at your facility to update date last seen and other data items. |

20200058 | Surgery of Primary Site/Surgery Codes, NOS--Pancreas: What exactly is an extended pancreatoduodenectomy? Must the entire pancreas be resected in order to use code 70? What minimal requirements must be met to use code 70? How should a Whipple with cholecystectomy, partial omentectomy, common hepatic excision, portal vein resection, and lymphadenectomy be coded? |
According to our research, a pancreaticoduodenectomy (PD) includes an en bloc resection of the pancreatic head, the common bile duct, the gallbladder, the duodenum, the upper jejunum, the distal portion of the stomach and the adjacent lymph nodes. The extended PD procedure includes extended lymphadenectomy, extended organ resection, and extended vascular resection and reconstruction. Code 70 could be assigned without the entire pancreas being resected. A Whipple procedure removes the head of the pancreas, duodenum, stomach and gallbladder and part the common bile duct. The portal vein resection is probably part of the common bile duct excision. If the omentectomy was performed for treatment of this primary, record it in "Surgical Procedure of Other Site." Record the lymphadenectomy in the lymph node data items. |

20200085 | Solid Tumor Rules (2018)/Histology--Head and Neck: What is the histology of paraganglioma, NOS arising outside of the adrenal gland (for example, in the bladder) for cases diagnosed 1/1/2021 and later? See Discussion. |
Should histology be coded as paraganglioma, NOS (8680/3) or as extra-adrenal paraganglioma, NOS (8693/3) for a diagnosis of paraganglioma in the bladder? Does the pathologist have to specifically diagnose the tumor as extra-adrenal paraganglioma, NOS to use histology code 8693/3? Or, does any diagnosis of paraganglioma (NOS) arising outside of the adrenal gland, carotid body, middle ear, or aortic body (the specified sites for other types of paragangliomas) qualify as an extra-adrenal paraganglioma, NOS? The ICD-O-3.2 Implementation Guidelines (Tables 6 and 7) provide an associated site of C755 for histology 8680/3 (paraganglioma, NOS), but no associated site code is provided for histology 8693/3 (extra-adrenal paraganglioma, NOS). If the preferred site for paraganglioma, NOS is the paraganglia, would a paraganglioma in the bladder be an extra-adrenal paraganglioma? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
Code the histology stated by the pathologist: paraganglioma, NOS 8680/3. |

20200066 | Reportability--Skin: Effective 2021, a cutaneous leiomyosarcoma is a related term for smooth muscle tumor, NOS (8897/1) in ICD-O-3.2. Currently, we have been capturing these as a C44_ (leiomyosarcoma, 8890/3) but the 2019 SEER inquiry states that atypical intradermal smooth muscle neoplasm (AISMN) was previously termed cutaneous leiomyosarcoma. This is not documented on the 2018 ICD-O-3 updates. Should this 2019 case be 8897/1 or 8890/3? |
Cutaneous leiomyosarcoma is reportable for 2019. Code histology to leiomyosarcoma 8890/3. As of cases diagnosed 1/1/2021, it is no longer reportable based on assignment to 8897/1 in ICD-O-3.2. |
