20230008 | SEER Manual/Surgery of Primary Site 2023--Breast: What instructions should be followed when the 2023 SEER Manual Appendix C 2023 Breast Surgery Codes advise to code 1 in Surgical Procedure of Other Site for a simple bilateral mastectomy but the 2023 STORE Manual does not. See Discussion. |
The 2023 SEER Manual, Appendix C 2023 Breast Surgery Codes, note reads: SEER Note: Assign code A760 for a more extensive bilateral mastectomy. Assign code 0 in Surgical Procedure of Other Site (NAACCR #1294). For a simple bilateral mastectomy, assign code A410 with code 1 in Surgical Procedure of Other Site (NAACCR #1294). In the 2023 STORE Manual, these notes are not mentioned and we are instructed not to code surgery to other site. Other education related to 2023 breast coding provided by NAACCR states to not code surgery to other site. |
Assign code 1 in Surgical Procedure of Other Site (NAACCR #1294) when a simple bilateral mastectomy is performed for a single tumor involving both breasts. This statement was inadvertently omitted from the STORE manual and will be added back in: For single primaries only, code removal of contralateral breast under the data item Surgical Procedure/Other Site (NAACCR Item #1294) or Surgical Procedure/Other Site at This Facility (NAACCR Item #674). The information presented by NAACCR was intended to be consistent with what is in the SEER manual. It may have been misuderstood. |

20230059 | Histology--Heme and Lymphoid Neoplasms: How is histology coded for a diagnosis stated as MDS/AML (myelodysplastic syndrome/acute myeloid leukemia) per the international consensus classification (ICC)? See Discussion. |
The final diagnosis on bone marrow biopsy was high grade myeloid stem cell neoplasm, 17% blasts by differential count. The pathologist further states that this could be classified as “MDS with increased blasts (MDS-IB2) per the WHO 5th edition classification, or MDS/AML per the international consensus classification (ICC).” FISH and cytogenetics revealed a loss of 7q, but no other AML-related genetic abnormalities. The physician confirms the patient has MDS/AML. |
Updated Answer July 2024 Code histology as myelodysplastic neoplasm with increased blasts (9983/3) based on the WHO Classification of Hematolymphoid Tumors, 5th edition, Beta version 2. WHO lists MDS with increased blasts-2 (MDS-IB2) as a subtype of 9983/3. Terms coded to 9983/3 include
When differences exist between WHO and ICC, assign the histology based on the WHO Classification. |

20230032 | Reportability/Histology--Thyroid: Is a diagnosis of papillary carcinoma, follicular variant, encapsulated/well demarcated, non-invasive reportable? See Discussion. |
The final diagnosis for a left thyroid lobectomy was Papillary thyroid microcarcinoma, further stated to be Histologic Type: Papillary carcinoma, follicular variant, encapsulated/well demarcated, non-invasive. The diagnosis comment states there is a small follicular pattern papillary microcarcinoma. Is the designation of “non-invasive” for this papillary follicular tumor equivalent to a non-reportable diagnosis of Non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP), 8349/1? Or should this be accessioned as either a reportable in situ (non-invasive) papillary follicular thyroid carcinoma or a papillary microcarcinoma per the diagnosis comment? |
Your case is equivalent to encapsulated follicular variant of papillary thyroid carcinoma, non-invasive (non-invasive EFVPTC) and is not reportable for cases diagnosed in 2021 or later even though it says "carcinoma." That is because the WHO assigned a behavior code of /1 to this entity (8349/1). NIFTP is assigned to the same histology and behavior code. |

20230030 | Primary site: Is there a physician priority list for coding primary site? For example, the surgeon states during a pancreatectomy that the primary is in body while the pathologist states in their synopitc report that primary is neck; neither is in agreement, or neither is available for confirmation. |
As a general rule, the surgeon is usually in a better position to determine the site of origin compared to the pathologist. The surgeon sees the tumor in its anatomic location, while the pathologist is often using information given to him/her by the surgeon and looking at a specimen removed from the anatomic landmarks. However, when a pathologist is looking at an entire organ, such as the pancreas, he/she may be able to pinpoint the site of origin within that organ. In the case of pancreas body vs. neck, the neck is a thin section of the pancreas located between the head and the body. It may be a matter of opinion whether a tumor is located in the "body" vs. the "neck." In the situation you describe, we would give preference to the surgeon and assign the code for body of pancreas, C251. |

20230040 | First Course Treatment/Hormone Therapy--Prostate: Is Lupron first course therapy in a patient who initially elected active surveillance for prostate cancer and then consented to treatment with Lupron? See Discussion. |
in March, the patient with stage cT1c, Gleason grade 7, prostate cancer elected active surveillance. In April, the patient consented to treatment with Lupron. There was no evidence of disease progression. According to the rules on page 161 of the 2023 SEER manual, we think the answer is yes, but the reporting hospital states that this is second course therapy. |
Code Lupron as second course therapy and code active surveillance as first course therapy in this scenario. The 2023 SEER Manual states to code all treatment data items to 0 or 00 (Not done) when the physician opts for active surveillance, deferred therapy, expectant management, or watchful waiting. Assign code 2 to Treatment Status. Active surveillance is not the same as "refusing treatment." Active surveillance is a valid option offered to the patient. The patient chose this option and later changed their mind. This is not a refusal of recommended treatment. Document all the details in the appropriate treatment text fields. |

20230065 | Solid Tumor Rules/Histology--Prostate: Is histology coded as 8045 (Combined small cell carcinoma) for a 2023 diagnosis of two-component carcinoma comprised of both acinar adenocarcinoma and small cell neuroendocrine carcinoma of the prostate? See Discussion. |
This patient does not have a previous diagnosis of prostate adenocarcinoma nor a previous history of androgen-deprivation therapy. Does the logic in the Other Sites Solid Tumor Rules (STRs) noted in SINQ 20200052 still apply? This SINQ confirms a diagnosis of mixed prostatic adenocarcinoma and small cell neuroendocrine carcinoma is 8045. This matches the STRs instructions for Rule H21 and Table 2 (Mixed and Combination Codes), row 1. Row 1 indicates a mixed small cell carcinoma and adenocarcinoma is combined small cell carcinoma (8045). For a patient without previous treatment, is this the correct mixed histology code? |
Code histology as combined small cell carcinoma (8045) based on the Other Sites Solid Tumor Rules, May 2023 Update, Table 2, Mixed and Combination Codes, for this mixed histology prostate carcinoma consisting of adenocarcinoma and small cell neuroendocrine carcinoma regardless of treatment status. This is similar to SINQ 20200052 that applies to one tumor with mixed histologies. |

20230045 | Reportability/Histology--Thyroid: Is a diagnosis of “angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma” reportable if the diagnosis comment states, additional immunostains were performed which demonstrate the carcinoma cells are positive for thyroglobulin and negative for calcitonin? See Discussion. |
Patient had a right thyroid lobectomy on 12/2022, with initial diagnosis of “thyroid carcinoma pending expert consultation for definitive classification.” The slide review documented in the addendum shows a final diagnosis of “Angioinvasive oncocytic thyroid neoplasm, see comment.” The subsequent comment states, “I would classify this lesion as an angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma.” The comment goes on to state, “Additional immunostains were performed which demonstrate the carcinoma cells are positive for thyroglobulin and negative for calcitonin. The diagnosis remains unchanged.” |
Do not report angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma based on the final, unchanged diagnosis. Worrisome is not a reportable ambiguous terminology. |

20230007 | SEER Manual/Reportability--Appendix: Is low-grade appendiceal mucinous neoplasm (LAMN) with peritoneal spread followed by evidence of extraperitoneal metastatic disease reportable prior to 2022? See Discussion. |
In 2021, the patient was diagnosed with a non-reportable appendiceal LAMN. Resection showed a tumor diffusely involving the appendix and perforating the visceral peritoneum, as well as extensive intraperitoneal metastasis. In 2023, a lung wedge resection revealed metastatic mucinous neoplasm involving lung parenchyma and pleura, consistent with metastasis of the known appendiceal primary. It is understood that intraperitoneal spread of an appendiceal LAMN does not make it reportable because the peritoneal disease is also non-invasive. Does extraperitoneal metastasis of an appendiceal LAMN diagnosed prior to 2022 make it invasive disease and therefore reportable? |
LAMN diagnosed prior to 1/1/2022 is not reportable even when it spreads or metastasizes according to our expert pathologist consultant. Spread of this neoplasm does not indicate malignancy. For this case to be reportable, the diagnosis must indicate “carcinoma” or “adenocarcinoma.” Pre-2022, LAMN is not reportable even when treated with surgery and chemotherapy. LAMN is reportable starting with cases diagnosed in 2022. |

20230003 | SEER Manual/Reportability--Ambiguous Terminology: Please clarify the reportability and relevant date ranges of the following ambiguous terminology: almost certainly, most certainly, and malignant until proven otherwise. See Discussion. |
SINQ 20180104 indicates, in the absence of further info, the terms “almost certainly” and “until proven otherwise” are NOT reportable. There is no date range provided for this answer. SINQ 20200027 indicates, in the absence of further info, the term “most certainly” IS reportable. There is no date range provided for this answer. SEER Program Coding and Staging Manual 2022 indicates, in the absence of further info, the terms “until proven otherwise” and “most certainly” ARE reportable. Essentially, we are hoping for an update of SINQ 20180104 due to 2022 reportability change. Clarification to the equivalence of “almost certainly” and “most certainly” would also be helpful. |
Use the ambiguous terminology list as a guide in the absence of additional information after reviewing all available information and consulting the physician who diagnosed and/or staged the tumor. Equivalent to "Diagnostic for" malignancy or reportable diagnosis
Not Equivalent to "Diagnostic for" malignancy or reportable diagnosis
We will update SINQ 20180104. |
