20240024 | Reportability/Histology: Is angiomyxoma (this includes borderline or behavior code /1 cases) of the soft tissue reportable? Can you provide us with coding guidelines for angiomyxoma for when its reportable or not reportable? |
Do not report angiomyxoma. ICD-O-3.2 assigns 8841/0 to this benign tumor. This includes superficial and deep (aggressive) angiomyxoma. |

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. |

20240020 | Histology/Behavior: There are currently no codes available on the ICD-10-CM casefinding list for several of the site-specific intraepithelial neoplasias (8077/2). Will there be an update with additional codes for these sites that currently do not have codes to enable casefinding for these? See the table below.
|
Many of these terms are not specified in the codes and definitions in ICD-10-CM. This is because ICD-10-CM does not have the same granularity as ICD-O-3.2. There are a few sites where intraepithelial neoplasia II and/or III are mentioned. Even though ICD-O-3.2 classifies these as /2 (in-situ), for the intraepithelial neoplasia that are listed in ICD-10-CM, Grade II is designated as benign, while Grade III is designated as in-situ. It is not clear if medical coding will change the Grade II to an in-situ code. All the in-situ codes (except cervix) are included in the casefinding list. Grade III is included with the in-situ codes; however, there is no guarantee that medical coders will code them as in situ. High grades are coded as in-situ in ICD-10-CM. For those where there is no specific intraepithelial neoplasia code, the benign codes will cover any benign lesion for that site. This would make for a lot of review using the codes for casefinding. Most of the benign codes were removed from the casefinding list a couple of years ago to make it more manageable. Use the casefinding list as a guide for these neoplasias. It is not the most definitive source due to the lack of specificity of ICD-10-CM. It is not possible to map every single histology to a specific code. It is also not known how medical coders across the U.S. are coding these neoplasias. For that reason, pathology should remain the foremost casefinding resource used. The casefinding team will need to review the prepared list below and determine what codes to add. Any updates will be incorporated in the FY2025 updates (October 2024.)

20240045 | Reportability/Ambiguous Terminology--Prostate: Should cases be reported and abstracted based on ambiguous terminology, e.g., suspicious for prostate cancer, when the physician is not treating the case as malignant? See Discussion. |
Please comment on these specific scenarios.
|
For each of your scenarios, the medical record information indicates that the case is not reportable based on physician opinion. Do not abstract these cases. Remember that the ambiguous terms list is to be used as a last resort. The ideal way to approach abstracting situations when the medical record is not clear is to follow up with the physician. If the physician is not available, the medical record, and any other pertinent reports (e.g., pathology, etc.) should be read closely for the required information. See page 19 in the SEER Manual, https://seer.cancer.gov/manuals/2024/SPCSM_2024_MainDoc.pdf |

20240042 | EOD 2018/EOD Primary Tumor--Cervix: How is Extent of Disease (EOD) Primary Tumor of the cervix coded when it invades into the bladder on surgery and noted as T4. No further information is provided, and it is not possible to contact the physician for clarification. Would you code 550 (Bladder wall; bladder, NOS excluding mucosa), 750 (Bladder mucosa), or 999 Unknown? |
Assign code 550 (Bladder, NOS excluding mucosa) to EOD Primary Site based on invasion into the bladder with no mention of mucosa. EOD Primary Tumor for cervix, Note 1, instructions are to use the extension information to code primary tumor in preference to a statement of FIGO stage when both are available. TNM staging is closely related to FIGO stage, and the surgical findings of bladder invasion NOS in this case should be used in preference to the statement of T4. |

20240053 | Reportability/Behavior--Kidney: Is a 2022 diagnosis of “clear cell renal cell papillary tumor” on nephrectomy reportable? See Discussion. |
We are aware that the WHO 4th edition for urinary tumors has changed the behavior of “clear cell papillary renal cell carcinoma” to /1 but registries are to continue collecting as /3. While the diagnosis in our case is stated as “tumor” it does seem like the pathologist may be using the new WHO terminology of “tumor” rather than “carcinoma,” so we are not sure if behavior is /3 or /1. |
Report clear cell renal cell papillary tumor (CCRCPT), formerly classified as clear cell renal cell papillary carcinoma, and assign code 8323/3 until this new term and code (8323/1) have been adopted by standard setters. The Kidney Solid Tumor Rules advise to code clear cell papillary renal cell carcinoma as 8323/3. WHO Classification of Tumors of the Urinary System and Male Genital Organs, 4th ed., has reclassified this histology as a /1. This change has not yet been implemented and it remains reportable. WHO Classification of Urinary and Male Genital Tumors, 5th ed., has since reclassified clear cell papillary renal cell carcinoma as CCRCPT (8323/1). The name change was made because there have been no reports of metastatic events for this indolent tumor. The term clear cell renal cell papillary carcinoma is no longer recommended. |

20240017 | EOD/Prostate Pathologic Extension--Prostate: Is a pathology report from a prostate biopsy/transurethral resection of the prostate that states "with intraductal spread" extraprostatic/extracapsular extension or localized? |
Code as a localized, intracapsular tumor as ductal carcinoma in situ does not invade. Intraductal spread is describing the neoplasm spreading through the acinar/ductal cells in the prostate specimen. It is an in-situ type of spread and not invasive but almost always presents with an invasive tumor. |

20240054 | EOD 2018/Primary Tumor--Breast: We are having difficulty deciding when we can or cannot use physician-assigned TNM staging to code EOD data items if the medical record or hospital abstract documentation is unclear. As a central registry, we are unable to query physicians for clarification. Please advise what is a “discrepancy” in the EOD General Instructions to “Use the medical record documentation to assign EOD when there is a discrepancy between the T, N, M information and the documentation in the medical record.” See Discussion. |
We know that physician TNM staging is not always accurate, and we also know that doctors sometimes use information in assigning their TNM which may not be available to registrars. Is it a discrepancy when the documentation in the chart is unclear or not definitive, yet the physician assigns a TNM that seems to incorporate that documentation? Or is a discrepancy an obvious conflict between chart documentation and the doctor’s staging – such as a mis-assignment of TNM category that doesn’t at all match with clear and complete medical record documentation, or the physician’s use of criteria that should be excluded from the TNM assignment per AJCC guidelines? A real case example is a patient with breast carcinoma, imaging states 12 cm tumor with thickening of dermis, and thickening of morphologically suspicious internal mammary and level 1-2 axillary lymph nodes. Medical oncologist states locally advanced breast cancer with extensive changes involving skin thickening associated with the mass, at least stage IIIC based on imaging and exam findings, cT4 N3b. Only axillary nodes were sampled and found to be positive. Post-neoadjuvant therapy resection showed only focal DCIS. Per EOD guidelines, would the oncologist’s staging be a discrepancy with the chart documentation and therefore ignored, with EOD-Primary Tumor coded 200 for skin thickening, and EOD-Lymph Nodes 200 for involvement of axillary nodes only? Or would the doctor’s TNM be a clarification/confirmation of documentation terms that we otherwise would not code, with EOD-PT coded 400 for extensive skin involvement and EOD-LNs 600 for internal mammary + axillary nodes? |
Use all information available in the medical record. EOD is a combination of the most precise clinical and pathological documentation of the extent of disease as instructed in the EOD 2018 General Instructions, Extent of Disease section. EOD 2018 General Instructions, General Coding Instructions section advises to use the medical record documentation to assign EOD when there is a discrepancy between the T, N, M information and the documentation in the medical record. When there is doubt that the documentation in the medical record is complete, code the EOD corresponding to the physician staging. A discrepancy can exist within the medical record when the information in the chart is unclear, incomplete, or conflicting, for example, the TNM staging from pathology differs from the medical oncologist’s TNM staging. In the scenario provided, use the medical oncologist stage information that takes into account imaging and exam findings. Based on the stage cT4 N3b, assign EOD Primary Tumor: 400 Extensive skin involvement WITHOUT a stated diagnosis of inflammatory carcinoma WITH or WITHOUT dermal lymphatic filtration EOD Regional Nodes: 600 Internal mammary node(s), ipsilateral, clinically apparent (On imaging or clinical exam) WITH axillary (level I, II, or III) lymph node(s), ipsilateral including infraclavicular |

20240021 | Solid Tumor Rules/Reportability/Histology--Digestive Sites: Is a diagnosis of “high grade dysplasia” (not specified to be squamous or glandular) reportable for esophagus, stomach, and small intestine for cases diagnosed beginning in 2024? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual indicates high grade dysplasia of esophagus, stomach, and small intestine are reportable. The ICD-O-3.2 does not include “high grade dysplasia” as equivalent to “high grade squamous dysplasia.” If reportable, would high grade dysplasia (NOS) that originates in the stomach and small intestine default to 8148/2, while esophageal high grade dysplasia (NOS) default to 8077/2? |
Report these high grade dysplasia of the following organs as stated below. Stomach: Assign code 8148/2 glandular intraepithelial neoplasia, high grade using the Other Sites Solid Tumor Rules, Table 6: Stomach Histologies and as described in the WHO Classification of Digestive Tumors, 5th edition. Small intestine and Esophagus: Assign code 8148/2 glandular intraepithelial neoplasia, high grade, using the Other Sites Solid Tumor Rules, Other Sites Histology Rules, Rule H4/H26. The following note is listed for both of these rules. Note: This list may not include all reportable neoplasms for 8148/2. See SEER Program Coding and Staging Manual or STORE manual for reportable neoplasms The Other Sites Solid Tumor Rules, Table 5: Esophagus Histologies and Table 7: Small Intestine and Ampulla of Vater Histologies will be updated to reflect this code as time permits. |

20240009 | Solid Tumor Rules/Histology --Brain and CNS: Why is high grade astrocytoma with piloid features (HGAP) not grouped together with the other astrocytoma histologies as a subtype/variant of astrocytoma? See Discussion. |
It appears there was some confusion about finding this new malignant HGAP tumor (2023+) code. If this is not a specific subtype/variant of astrocytoma, can clarification be added to the “New for 2023” entry for HGAP? |
HGAP is listed as a separate classification and is not a subtype of the diffuse gliomas. WHO Classification of Tumors of the Central Nervous System, 5th edition, has two categories dealing with non-pediatric astrocytic tumors: Adult-type diffuse gliomas Circumscribed astrocytic tumors HGAP falls into the second category as a result of updates to the 4th edition WHO classification in 2016 with advances in the role of molecular diagnostics with the 5th edition. All astrocytic tumors were previously grouped together whereas not all diffuse gliomas (astrocytic or not) are grouped together on the basis of growth pattern and behaviors, and shared IDH1 and IDH2 genetic status. The new classification separates astrocytomas that have a more circumscribed growth pattern, lack IDH gene alterations, and sometimes have BRAF mutations (i.e., pilocytic astrocytoma). The impact of molecular advances has driven classification changes as described in the 5th edition. Review of site/histologiy combinations for CNS neoplasms is currently being performed by Cancer PathCHART experts. It's possible they will recommend HGAP be moved to a subtype/variant of astrocytoma, NOS. |
