20190075 | Sex: How should the sex field be coded for the newly allowable non-binary gender designation ? See Discussion. |
Washington State added to birth certificates, which allows people to have their certificates changed to this non-binary gender designation. Gender X is defined as a gender that is not exclusively male or female, including, but not limited to: intersex, agender, amalgagender, androgynous, bigender, demigender, female-to-male, genderfluid, genderqueer, male-to-female, neutrois, nonbinary, pangender, third sex, transgender, transsexual, Two Spirit, and unspecified. |
Code Gender X as 9 when that is the only information available. Use text fields to document the details. Also refer to coding instruction #7. When gender is not known Assign code 1 when the primary site is C600 'C639 Assign code 2 when the primary site is C510 'C589 Assign code 9 for primary sites not included above |

20250009 | Sequence Number--Central/Reportability--Heme & Lymphoid Neoplasms: Is a hematolymphoid disease included in the sequencing if it was not reportable at the time of diagnosis? |
Do not include the disease in the sequencing if the original hematolymphoid disease was not reportable at time of diagnosis.
The 2025 SEER Manual Sequence Number--Central Coding Instruction 1.a advises: A ‘reportable’ primary refers to the site/histology/behavior of the tumor and the years when reporting was required. Review of the reportability requirements in effect during the diagnosis year will be needed. |

20190021 | Sequence Number Central--Brain and CNS: How is Sequence Number--Central coded for current/recent benign brain/CNS tumors when the patient has a history of an additional non-malignant CNS tumor diagnosed prior to 2004 (when these tumors became reportable to SEER)? See Discussion. |
We are confused by the SEER Program Coding and Staging Manual 2018 instruction that states: This sequence number counts all tumors that were reportable in the year they were diagnosed even if the tumors occurred before the registry existed or before the registry participated in the SEER Program. Does this rule apply to benign and borderline CNS tumors? Does this mean that any non-malignant CNS tumor diagnosed prior to 2004 should NOT be included in the sequencing (in the 60s range) if we were collecting non-malignant CNS per our State Registry reporting requirements prior to 2004? Example: Patient has a March 2017 diagnosis of right sided vestibular schwannoma (C724-1, 9560/0) and a prior history of left sided acoustic neuroma (c724-2, 9560/0) diagnosed in 1991. How should sequence be coded for each primary in our file? |
For your example, code the Sequence Number--Central as 61 for the 1991 diagnosis if this was a state registry requirement in 1991 and code 62 for the 2017 diagnosis. |

20150043 | Seq no-central--Brain and CNS: How should subsequent tumors be sequenced when the patient has a history of a brain tumor, with no information on the behavior of the brain tumor? According to the sequencing rules, it appears some assumption must be made regarding the behavior of the brain tumor. |
Sequence the brain tumor in the 60-87 series when you do not know the behavior. If you have reason to believe the brain tumor was malignant, sequence it in the 00-59 series. |

20170078 | Scope of Regional Lymph Node Surgery--Lung: How do you code Regional Nodes Positive, Regional Nodes Examined, and Scope of Regional Lymph Node Surgery when a fine needle aspirate (FNA) or biopsy of supraclavicular lymph nodes is positive for a lung cancer primary? Supraclavicular lymph nodes are distant in SEER Summary Stage and regional by AJCC. See Discussion. |
There is a discrepancy in regional lymph nodes for lung between SEER and AJCC. Supraclavicular lymph nodes/cervical lymph nodes are distant for SEER but regional for AJCC. For SEER states, when there is an FNA or biopsy of a supraclavicular lymph node performed and it is positive for a lung primary and no other lymph nodes are examined, do you code 95 in Regional Nodes Positive/Regional Nodes Examined and code "1" for Scope of Regional Lymph Node Surgery or do you not count the FNA/biopsy of the supraclavicular lymph node since it is distant? |
For cases diagnosed through 2017, use the Collaborative Staging (CS) system to determine regional versus distant lymph nodes. Supraclavicular lymph nodes are regional for lung in CS. Please note that Summary Stage is not the same as EOD, CS, or AJCC staging. Registrars should not use Summary Stage definitions for anything other than directly assigning the Summary Stage field. |

20210001 | SEER*RSA/Required data items--Melanoma: The site-specific data item, Ulceration, states it is required by "All" in SEER*RSA but in the NAACCR Data Dictionary table it states is it required by SEER, Commission on Cancer (CoC), and Canadian Cancer Registry (CCCR), not the National Program of Cancer Registries (NPCR). Does the definition of "All" in SEER*RSA not include NPCR? Also, please explain the difference between Required by: "All" and "Required by CCCR/Canada, COC, NPCR, SEER" (all listed out). |
Use the NAACCR Data Dictionary Required Status Table or refer to standard setter requirements. Do not use SEER*RSA to determine which data items are required to be collected or transmitted. Though "All" in SEER*RSA generally refers to the standard setters including CoC, NPCR, CCCR, and SEER, some items in SEER*RSA need updating; this is planned for 2022. |

20160071 | SEER Summary Stage 2000--Melanoma: Can Clark's level classification still used to Summary Stage melanoma? It was previously used by AJCC TNM, but was not included in the 7th edition. I see it is still listed in the CAP protocols for melanoma. |
Clark's level can be used to assign in situ, localized or regional summary stage.
If there is a discrepancy between the Clark’s level and the pathologic description of extent, use the higher Summary Stage code. |

20250019 | SEER Manual/Tumor Size Summary--Breast: Can the size of a non-mass enhancement (NME) be used if it represents the largest size within the appropriate time frame to code tumor size summary when neoadjuvant therapy is administered? Clinical and pathologic tumor sizes are no longer collected for 2024 and 2025 cases. See Discussion. |
In the SEER Program Coding and Staging Manual 2023, under clinical tumor size (page 115, item #12), it states: “For breast tumors, clinical size may be recorded based on the size of a non-mass enhancement (NME). NME is defined as an enhancing abnormality that is not associated with the three-dimensional volume of a mass, shape, and outlining, and it is separate from Background Parenchymal Enhancement (BPE).” This guidance does not appear to have been carried forward into the Tumor Size Summary coding instructions. |
Do not use the NME size from magnetic resonance imaging (MRI) to code tumor size when both tumor size and NME size are stated or if NME is the only size available. The size of the solid tumor mass takes priority over the size of the NME when provided separately and the NME is larger. The American College of Radiology, Breast Imaging Reporting and Data System (BI-RADS) defines NME as an area of enhancement on MRI that does not belong to a 3D mass or have distinct features of a mass. It is a separate descriptor from size that includes modifiers describing enhancement patterns with a specific MRI pattern. |

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. |

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. |
