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. |

20240007 | Histology--Brain and CNS: Provide clarification about the priority order of histology coding sources and an explanation of why the annotated histology lists are not the same as the WHO IARC ICD-O-3.2 Excel Table (adopted 1/1/2021). See Discussion. |
We have had multiple users unable to find the applicable histology in the ICD-O-3.2 (i.e., the site-specific table did not include the histology) because they were using the annotated histology list and could not find the complete list of related terms or synonyms for the histology code. For example, the ICD-O-3.2 lists Medulloblastoma, SHH-activated, NOS as a related term for 9471/3, but many users were unable to find this valid histology because they were using the annotated histology list, not the ICD-O-3.2. |
The NAACCR Annotated Histology List (AL) serves as an aid to registry software vendors for implementing annual histology changes. This file has been maintained by the Registry Plus team at CDC’s NPCR for several years and reflects modifications to ICD-O-3 implemented by North American cancer registries over time. Although this list is reviewed multiple times prior to posting, there is no guarantee of 100% accuracy. As such, the AL is not a substitute for referring to various standard-setter documents and implementation guidelines. In this instance, Medulloblastoma Desmoplastic SHH-activated and TP53-wildtype 9471 is across several resources: the Solid Tumor Rules, Malignant CNS and Peripheral Nerves module in Table 3, column 3 as a subtype/variant of Medulloblastoma NOS 9470; in the CNS WHO 5th Edition BB; and in the WHO IARC ICD-O-3.2 posted to ICD O 3 Coding Updates (naaccr.org). Although the exact related term of Medulloblastoma, SHH-activated, NOS is not listed, the NAACCR Implementation Guidelines for 2024 recommend checking the 2024 ICD-O-3 Update Table 1 or 2 to determine if the histology is listed. If the histology is not included in the update, then review ICD-O-3.2 and/or Hematopoietic and Lymphoid Database and/or Solid Tumor Rules (MP/H). The Cancer PathCHART initiative has been undertaken to address gaps such as this between standard setting resources. Having all the standard histology coding resources included in a single all-inclusive database enables alignment of morphology codes & terms included in the CPC*SMVL (Cancer PathCHART Site-Morphology Validation List), Solid Tumors Rules, ICD-O-3 Annual Updates, NAACCR Annotated Histology List as well as the WHO 5th edition Blue Books. Please see Cancer PathCHART - Tumor Site-Morphology Surveillance Standards Initiative for more information on the Cancer PathCHART initiative, and more specifically, see Transitioning the Annotated Histology List to Cancer PathCHART (naaccr.org). |

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. |

20240025 | Update to the current manual/Reportability--Esophagus: Is high grade dysplasia of the esophagus reportable? The 2024 Seer Program Manual, page 21, has an example that states it is not reportable. See Discussion. |
Example 4: Esophageal biopsy with diagnosis of “focal areas suspicious for adenocarcinoma in situ.” Diagnosis on partial esophagectomy specimen “with foci of high grade dysplasia; no invasive carcinoma identified.” Do not accession the case. The esophagectomy proved that the suspicious biopsy result was false. Appendix E2 #32 of the SEER Manual states high grade dysplasia in site other than stomach, small intestines, and esophageal primary sites are not reportable. Does this mean high grade dysplasia is reportable for esophagus primaries? |
High grade dysplasia of the esophagus is reportable. The example will be corrected in the next edition of the SEER manual. |

20240018 | Solid Tumor Rules/Histology--Head and Neck, Other Sites: Please provide clarification about effective dates for using p16 testing to assign HPV-related histology codes for various primary sites. See Discussion. |
1. The 2022 and 2023 SEER Program Coding Manuals state under Histologic Type ICD-O-3: Beginning with cases diagnosed 01/01/2022 forward, p16 test results can be used to code squamous cell carcinoma, human papilloma virus (HPV) positive (8085) and squamous cell carcinoma, HPV negative (8086). NAACCR 2023 Implementation Guidelines contain similar instructions on HPV histologies for cervix, vulva and vagina that are applicable back to 2022 (2021 for cervix). The current Other Sites Solid Tumor Rules state on the Histology tables for anus, cervix, vagina, vulva, and penis and scrotum: "p16 is a valid test to determine HPV status and can be used to code HPV associated and HPV independent histologies." Since Other Sites Solid Tumor Rules apply to cases diagnosed 2023+, can p16 results only be used from 2023 onward, to code HPV-related histologies for primaries that fall under the Other Sites module? Or per the 2022 SEER Manual statement and NAACCR 2023 Implementation Guidelines, could a p16-confirmed HPV histology code also apply to a 2022 Other Sites case and if so, is that only for cervix, vulva, and vagina? Further complicating the matter are the 2024 ICD-O-3.2 update documents indicating these codes are valid 1/1/2024+ for the “Other Sites” penis and scrotum. 2. Is using p16 testing for HPV-related histology codes ONLY allowed for sites in the Solid Tumor tables that contain the statements about p16 (Head & Neck Table 5, and the Other Sites tables noted above for anus, cervix, etc.)? Or could it apply to primary sites outside of those tables; for example, a 2022 pathology report from the ethmoid sinus C311 indicating an HPV-related histology based on p16 testing? The ICD-O-3 Annotated Histology lists include C310-C313 among the common site codes for 8085 and 8086. The Head and Neck Solid Tumor Rules “New for 2022” section and rule H1 Note 4 also mention that p16 can be used to code HPV histologies; these sections would seem to apply to all sites in that module, since only the more common histology codes are listed in the tables and if not, we are instructed to use ICD-O. |
Per 2024 Cancer PathCHART expert pathologist review, morphology codes 8085/3 and/or 8086/3 are valid and applicable to head and neck, oropharynx, cervix, vagina, vulva, fallopian tube, anus, and penis scrotum (reference: Cancer PathCHART: Product Downloads and Timelines). The Cancer PathCHART SMVL will be updated for C632, Scrotum, with the next release of the NAACCR Edits Metafile, currently scheduled for May 2024. Assign histology codes 8085 and 8086 for the sites listed in the Solid Tumor Rules histology tables. The codes 8085 and 8086 are applicable for a small group of sites according to the year they became valid for implementation as follows. Head and Neck Oropharynx, Base of Tongue, Tonsils, Adenoids (2022+) Other Sites Cervix (2021+) Anus (2023+) Vagina (2023+) Vulva (2023+) Penis (2024+) Scrotum (2024+) While ICD-O-3.2 and Cancer PathCHART list additional sites such as Accessory Sinuses, they have not yet been implemented in the U.S. |

20240039 | Update to Current Manual/Race: For the Example #15 under Race Coding Examples in the 2024 SEER manual, could coding these as 97 result in an under-reporting of Native Hawaiians? See Discussion. |
The race category in some hospital electronic medical record systems includes a combined category of “Native Hawaiian/Pacific Islander.” What race code should be used in a situation where the only available information is “Native Hawaiian/Pacific Islander?” |
Change to current instructions. We will update this example in the next edition of the manual. The new example will instruct registrars to look for other descriptions of the patient’s race. When no other information is available, assign 07, Native Hawaiian, in Race 1 and assign 97, Pacific Islander, NOS in Race 2. Begin following this new instruction now. |

20240038 | Solid Tumor Rules/Multiple Primaries--Brain and CNS: How many primaries are accessioned, and what M Rule applies to a 2023 diagnosis of pituitary macroadenoma followed by a 2024 diagnosis of pituitary neuroendocrine tumor (PitNET) when the patient did not undergo surgery, but did undergo hormone therapy with Cabergoline? See Discussion. |
Malignant Central Nervous System (CNS) Rule M5 instructs us to abstract a single primary (as malignant) when a single tumor is originally diagnosed as non-malignant, the “First course treatment was active surveillance (no tumor resection),” and the subsequent resection pathology is malignant. This patient’s first course of treatment was not active surveillance. While the patient did not have first course tumor resection, the tumor was treated with Cabergoline. Should Rule M5 apply because there was no tumor resection? If so, should Rule M5 clearly state no tumor resection is the criteria (not active surveillance)? SINQ 20230023 does indicate a PitNET diagnosis following a diagnosis of pituitary adenoma does not fall into standard rules, but in the previous SINQ the first course treatment was a partial resection. It is unclear whether other types of treatment could result in a new malignant PitNET, following a previously treated non-malignant pituitary tumor. |
Abstract a single primary as 8272/3 (pituitary adenoma/PitNET) using the Malignant CNS and Peripheral Nerves Solid Tumor Rules, Rule M2, a single tumor is always a single tumor. Change the histology of the 2023 diagnosis to 8272/3. This scenario does not meet the criteria in the current rules for M5 in that it requires a resection as part of the criteria. Since the patient did not undergo resection for either diagnosis, the 2024 diagnosis may indicate recurrence or progression. A diagnosis of pituitary adenoma only is still coded 8272/0 (this code is still valid). A diagnosis of pituitary adenoma/PitNET, PitNET, or pituitary neuroendorine tumor is coded 8272/3. Cabergoline is used to treat prolactinoma or high levels of prolactin but does not impact the PitNET. |

20240003 | Solid Tumor Rules/Histology--Head & Neck: How is histology coded for laryngeal intraepithelial neoplasia II-III (LIN II or LIN III)? See Discussion. |
Laryngeal intraepithelial neoplasia II-III is not included in the ICD-O-3.2 and, while the SEER Program Coding and Staging Manual (SPCSM) confirms this is reportable, neither the SPCSM nor the Solid Tumor Rules Manual provide the specific histology to use for LIN II or LIN III. Should this be coded as 8077/2 since this is most like a high grade squamous dysplasia? |
Assign histology code, 8077/2 (squamous intraepithelial neoplasia, high grade) for LIN III and for LIN II. ICD-O-3.2 lists squamous intraepithelial neoplasia, grade II and grade III as 8077/2 indicating it is reportable. ICD-O-3.2 does not list every site-specific type of intraepithelial neoplasia. Check the SEER manual for reportable and non-reportable examples. |

20240030 | Reportability/Primary Site--Skin: Is squamous cell carcinoma (SCC) that overlaps skin and the vermillion border reportable when the percent of overlap is unknown? See Discussion. |
SINQ 20031110 addresses an overlapping lip lesion between skin and the vermillion border. We were instructed to go with area of greatest involvement. Case would be reportable if >50% of tumor was on the vermillion border and site would be coded to vermillion border (C00._). Often times percentage of involvement is not stated and all that is known is that the lesion overlaps skin and mucosa. |
Determine whether the lesion is on the mucosa or skin based on the pathology report, history and physical, and operative notes when available. The gross description of the pathology report should include information to help in determining whether the site of origin is epithelium (skin) or mucosa (lip). Do not report the case when the site of origin cannot be determined between a reportable site and non-reportable site for this histology. This includes situations where the site of origin or the site with the greatest involvement is undetermined. In this case, you cannot confirm reportability. |

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.
