20240058 | Summary Stage 2018--Ovary: What is the summary stage for an ovarian primary in 2024, in which the ovary capsule was ruptured with surgical spill? See Discussion. |
In this case, the surgeon ruptured the ovarian tumor to drain it prior to removal causing the surgical spill. Regional lymph nodes are negative and there is no metastasis. The capsule was then noted as ruptured on pathology. Does it matter if the surgeon was the one who ruptured the capsule? Would the stage change if the surgeon intentionally ruptured the capsule to drain the tumor intraoperatively causing some surgical spill? The scenarios of an intentional and not intentional rupture are not specified in SEER Summary Stage 2018. |
Code SEER Summary Stage 2018 to Localized, Code 1. Per consult with AJCC and noted in the Primary Peritoneal Chapter in AJCC 8th edition, an intraoperative rupture is coded as a surgical spill. A capsule rupture is when the capsule ruptures prior to the surgery (Summary Stage Regional, Code 2). |

20240059 | Update to the Current Manual/SEER*RSA--SEER Site-specific Factor 1: The 2024 SEER Manual and SEER*RSA say that Codes 10-51 are hierarchical; use the highest code that applies (10 is highest, 51 is lowest). Should the guidance say that 51 is highest, 10 is lowest since code 10 is a HPV negative p16 test? |
Assign the highest code with 51 as the highest and 10 the lowest when there is more than one test performed with differing results. The SEER Manual will be updated in the 2025 release. SEER*RSA will be updated in a future release, version 3.3 in 2026, as version 3.2 has been updated for 2025. |

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. |

20240061 | Heme & Lymphoid Neoplasms/Histology--Myelodysplastic Neoplasm: What is the histology code for myelodysplastic neoplasm with low blasts and SF3B1 mutation with primary site bone marrow (C421) diagnosed in 2023? |
Assign histology as 9982/3 (myelodysplastic neoplasm with low blasts and SF3B1 mutation). This is a new term for 9982/3. WHO Classification of Hematolymphoid Tumors, 5th edition, defines myelodysplastic neoplasm (MDS) with low blasts and SF3B1 mutation (MDS-SF3B1) as a myeloid neoplasm with cytopenia and dysplasia characterized by SF3B1 mutation and often ring sideroblasts. |

20240062 | Reportability--Brain and CNS: Is an MRI finding of “statistically meningioma” reportable? See Discussion. |
Example: Patient has a 2023 brain MRI described as having a “new dural based nodule, statistically meningioma, along the left distal tentorial incisura.” All subsequent chart information is related to patient’s unrelated diagnosis of multiple sclerosis only. Is the terminology “statistically” reportable ambiguous terminology in this context? |
If you cannot clarify this with the involved physicians, do not report this case of meningioma based on information provided. There is no indication that the patient was treated or further evaluated for meningioma. |

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. |

20240066 | Histology--Heme & Lymphoid Neoplasms: How should histology be coded for a pathologic diagnosis of “Follicular lymphoma, diffuse pattern grade 3A of 3, equivalent to diffuse large B cell lymphoma (germinal center cell type)” when later referenced clinically as follicular lymphoma grade 3A? See Discussion. |
The WHO Classification of Hematopoietic Tumors (Blue Book), 5th edition states: “Rare cases of classic follicular lymphoma with cytological features of follicular lymphoma (FL) grade 3A can present with a prominent diffuse pattern. In the previous edition, such cases were defined as diffuse large B-cell lymphoma (DLBCL). Currently, it is uncertain whether such cases should be classified as FL or diffuse large B-cell lymphoma; and in such cases, individual treatment choices should be made in multidisciplinary conference settings taking into consideration clinical, laboratory, and imaging parameters. The presence of diffuse areas composed entirely or predominantly of large cells, however, warrants a diagnosis of diffuse large B-cell lymphoma.” Our concern is that the Hematopoietic (Heme) Manual and Database do not provide instruction for coding this scenario. We hesitate to interpret the terms “equivalent to” as ambiguous because one could argue it is unambiguous. Barring this argument, the M and H rules would indicate this is a diagnosis of diffuse large B-cell lymphoma. However, the physician does not seem to agree with the pathologist. |
Assign histology as DLBCL (9680/3) as supported by the WHO Classification of Hematolymphoid Tumors, 5th edition. It is consistent with how it would have been coded in the 4th edition. The Heme Manual and Database currently are based on the 4th edition. Physicians are using the 5th edition blue book, whereas the cancer registry field is not yet at this time. Regarding the Heme Manual and Database, this type of scenario is not covered because it is part of the 5th edition WHO Blue Book. The database cannot be updated until the 5th edition is approved for implementation (2026). |

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 he 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. |
