20240064 | Primary Site/Histology--Ovary: We are encountering a primary site, histologic type, and behavior combination edit based on the Cancer PathCHART (CPC) tables. Using the CPC*Search tool, C569 and 8441/3 is a valid combination. The diagnosis date is 01/13/2024. Should an over-ride be applied with this combination? |
The CPC Validity Status of the site morphology combinations of C569/8441/3 and C569/8441/2 was revised from Valid to Unlikely with the latest release of the Version v24A Edits Metafile. As a result, this site and morphology combination will now require an over-ride flag to be set. Code as 8461/3 (high-grade serous carcinoma) or 8460/3 (low-grade serous carcinoma) if at all possible. Use 8441/3 (serous carcinoma, NOS) only if it cannot be distinguished as low grade or high grade. The codes for high-grade serous carcinoma and low-grade serous carcinoma are relatively new. High-grade serous carcinoma and low-grade serous carcinoma are very different tumors and pathologists should state whether it is high grade or low grade. Please make every attempt to use the newer codes. If unable to determine high gade versus low grade, assign 8441/3 and override the edit. The files on the CPC website are currently being updated, and CPC*Search will be updated to reflect the changes sometime this Fall. |

20240040 | First course treatment--Kidney: How should the different treatment fields be coded if surgery is planned but cancelled due to patient noncompliance, then the tumor is treated with ablation, and eventually surgery is given due to residual disease? See Discussion. |
Patient was diagnosed in July 2022 with biopsy confirmed left kidney renal cell carcinoma. Initially, partial nephrectomy was planned for February 2023 but canceled at the last moment due to the patient’s “history of narcotic use.” The details of that cancellation were otherwise unclear. It appears the treatment plan was changed due to patient non-compliance. Patient then had cryoablation of the tumor in May of 2023. Subsequent imaging in October found residual tumor, but no disease progression was noted. Again, additional ablation was offered but patient decided on surgical treatment which did not occur until December 2023. Is the cryoablation second course due to a change of plan if there is no disease progression, recurrence, or treatment failure? If the cryoablation is first course treatment, then would the partial resection also be first course treatment because it was documented as the treatment plan? |
The treatment with cryoablation is second course. Once the initial treatment plan is changed, everything after the change is no longer first course of treatment. If the cryoablation was not mentioned as part of the original treatment plan, it is second course. |

20240026 | Update to Current Manual/Reportability--Pancreas: For cases diagnosed 2024+, is a diagnosis of pancreatic intraepithelial neoplasia II (PanIN II) reportable? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual: Reportability – Reportable Diagnosis List indicates pancreatic intraepithelial neoplasia (PanIN II) (C250-C259) is reportable. However, the ICD-O-3.2 lists “Glandular intraepithelial neoplasia, grade II” and “Glandular intraepithelial neoplasia, low grade” as histology code 8148 with behavior of /0 (benign). |
Do not report PanIN II. WHO Classification of Digestive Tumors, 5th edition, now categorizes PanIN into two categories, low grade (8148/0) and high grade (8148/2). PanIN grade I and PanIN grade II are categorized as PanIN low grade; PanIN grade III is categorized as PanIN high grade. We will update the Reportability section of the manual. |

20240016 | Histology/Behavior--Head and Neck: What is the histology code for sinonasal glomangiopericytoma in 2023? See Discussion. |
6/8/2023 A. Left nasal mass: Sinonasal glomangiopericytoma B. Additional left nasal mass: Sinonasal glomangiopericytoma Is this a borderline tumor? I am unable to find in this in the ICD-O-3 purple book or the Head and Neck Solid Tumor Rules. |
Assign histology code 8815/3 per ICD-O-3.2. Sinonasal glomangiopericytoma is also referred to as a sinonasal hemangiopericytoma. Prior to 2021, it was coded as 9150/3. |

20240077 | 2024 SEER Manual/Primary Site--Retroperitoneum: What is the primary site code for a final diagnosis of endometrioid adenocarcinoma from a biopsy of a right retroperitoneal mass? See Discussion. |
An 80-year-old post-menopausal female (status post hysterectomy for benign reasons) presents with a retroperitoneal mass on imaging. The pre-operative imaging shows the cervix and uterus are absent. Patient undergoes a robotic left salpingo-oophorectomy with biopsy of the retroperitoneal mass. |
Code Primary Site to C480 (retroperitoneum). Endometrial tissue may "break away” from the uterus and implant throughout the pelvic and abdominal cavities. This can occur in patients who suffer from endometriosis. This tissue remains behind when surgical removal of the uterus is done. Common sites of implantation are colon, peritoneum, retroperitoneum, and bladder. These cells may become malignant. When the uterus is no longer present (patient had surgical removal), code the site where the carcinoma was identified. The site-morphology combination of C480 and 8380/3 was designated as an unlikely site-morphology combination by the Cancer PathCHART expert pathologist review, as this is a rare type of tumor. Assign a value of 1 in the Over-ride Site/Type [2030] data item in order to pass the Primary Site, Morphology-Type, Beh ICDO3, 2024 (SEER) edit. |

20240076 | SEER Manual/Reportability--Vulva: Is vulvar intraepithelial neoplasia (VIN II) alone reportable? An example is a final diagnosis from a pathology report that states only 'VIN II' with no additional details/wording. |
Report VIN II. The 2024 SEER Manual lists this as a separate diagnosis in the Reportability section under Malignant Histologies 1.a.x. |

20240008 | Solid Tumor Rules/Histology--Brain and CNS: Should the term “diffuse” be added to Note 2 in the Non-Malignant Central Nervous System (CNS) Solid Tumor Rules, Table 6: Specific Histologies, NOS, and Subtypes/Variants, for the papillary glioneuronal tumor 9509/1? See Discussion. |
Should Note 2 state, "Beginning with cases diagnosed 1/1/2023 forward, diffuse leptomeningeal glioneuronal tumor is coded 9509/3? See the Malignant CNS rules." Currently the Note only states, "leptomeningeal glioneuronal tumor," but the histology that changed behavior is listed in both Table 6, Column 1 (Non-Malignant CNS) and Table 3 (Malignant CNS) as, "Diffuse leptomeningeal glioneuronal tumor." |
The correct term is diffuse leptomeningeal glioneuronal tumor listed as a synonym in Column 2. We will add the term diffuse in Note 2, Column 1 with the 2025 updates. In the meantime, you can add "diffuse" to your pdf version until the update is published. |

20240060 | Solid Tumor Rules/Histology--Lung: What is the histology code for a lung case with a diagnosis only stated as "high-grade neuroendocrine tumor" in 2022? As the disease was advanced, limited workup was done, and no more specific diagnosis was provided. See Discussion. |
SINQ #20170064 states this should be coded as neuroendocrine carcinoma for rectum, but that may not apply for a 2018+ lung case. The Solid Tumor Manual lists "neuroendocrine tumor, grade 3" as 8249 in the Lung module, Table 3, but our pathology report does not specify grade 3 and we are unsure if that would be equivalent to "high grade" in this case. We were unable to find this exact term in the Solid Tumor Manual or the ICD-O-3.2 update documents. |
Assign 8249/3 for high-grade neuroendocrine tumor of the lung. WHO Classification of Thoracic Tumors, 5th edition, defines two subtypes of neuroendocrine tumor of the lung, typical carcinoids (8240/3), and atypical carcinoids. WHO assigns typical carcinoid/neuroendocrine tumor grade 1 as 8240/3 and atypical carcinoid/neuroendocrine tumor grade 2 as 8249/3. They are regarded as low-grade and intermediate-grade, respectively. The preferred term for 8249/3 in ICD-O-3.2 is neuroendocrine tumor grade 2, with neuroendocrine tumor grade 3 as a related term. The Lung Solid Tumor Rules assign atypical carcinoid as 8249/3. |

20240029 | Solid Tumor Rules/Multiple Primaries--Head and Neck: Is a 11/2023 diagnosis of invasive squamous cell carcinoma (SCC) in lower gum (C031) a new primary and what rules apply for a patient with 09/2017 invasive SCC of lower gum (C031) and 05/2022 invasive SCC of lateral tongue (C023)? See Discussion. |
The 11/2023 lower gum tumor is a separate tumor occurring after a disease-free interval, so we know the Head and Neck Multiple Tumors Module applies. However, our staff is having difficulty applying the rules to this particular scenario with consistent results. Is the 11/2023 SCC a non-reportable recurrence per M12, since M4 is ignored due to patient’s prior 2017 C031 (lower gum) primary, and then M6 is ignored due to patient’s prior 05/2022 C023 primary? Or is the 11/2023 SCC a new primary per M4, since the last diagnosis was in a site differing at the third character (C03 vs C02)? If M4 does not apply due to patient's previous C03 primary, then does M6 apply since it has been more than 5 years since the previous C03 primary? |
Abstract three primaries for the scenario you describe.

20240070 | Reportability/Histology: Does Cancer Pathology Coding Histology And Registration Terminology (Cancer PathCHART) determine if the histology is reportable or do we have to use the Excel ICD-O-3.2 spreadsheet? |
The CPC ICD-O-3 Site Morphology Validation Lists (SMVLs) designate all tumor site-morphology combinations that are either valid or impossible as determined for the sites reviewed by the Cancer PathCHART initiative. These lists provide information on the Validity Status of specific tumor site and morphology combinations, similar to the way the ICD-O-3 SEER Site/Histology Validation List used to. However, the CPC SMVLs do not include information on the reportability of specific tumor site and morphology combinations. For tumor reportability, you will continue to use the Excel ICD-O-3.2 spreadsheets posted to the NAACCR ICD-O-3 Coding Updates website: https://www.naaccr.org/icdo3/, and the most recent SEER Manual and federal, state, local, and other standard setters' reportability requirements. |
