20031052 | Diagnostic Confirmation--Hematopoietic, NOS: Is a multiple myeloma diagnosed by an FNA of the lumbar spine (or any other non-bone marrow location) a diagnostic confirmation 1 or 2? See Description. |
Does the rule on page 111 of the SEER Program Coding Manual, 3rd Edition, for code 1 apply to myelomas (in the same way it applies to leukemias)? |
Assign code 1 [Positive histology] for aspiration of bone marrow. This rule is not limited to leukemias. |

20250014 | Race/Spanish Surname or Origin: How are Race 1 and Spanish Surname or Origin coded for the following race/ethnicity statements: "INDIGENOUS-LATINO/A OR INDIGENOUS-LATINX" and "FIRST NATIONS"? See Discussion. |
One of the largest hospital systems in our area includes "INDIGENOUS-LATINO/A OR INDIGENOUS-LATINX" and "FIRST NATIONS" as dropdown items for patients to self-select for race/ethnicity. This hospital system serves 51 hospitals and 1,000 clinics across Alaska, California, Montana, New Mexico, Oregon, Texas, and Washington. If "INDIGENOUS-LATINO/A OR INDIGENOUS-LATINX" is the only item selected with no additional text info available, how should Race 1 and Spanish Surname or Origin be coded? If "FIRST NATIONS" is the only item selected without additional text info available, should Race 1 be coded as 03? |
Assign code 01 (White) for Race 1 when described as Indigenous-Latino/a or Indigenous-Latinx. Indigenous-Latinx is an umbrella term for Indigenous migrants to the United States from Latin America including South and Central America, the Caribbean, and Mexico (for example, Maya, Mixteco, Purépecha, Taino, Zapoteco, etc.). Latin America is listed in Appendix D of the 2025 SEER Manual as White. Assign code 6 (Spanish, NOS; Hispanic, NOS; Latino, NOS) for Spanish Surname or Origin for Indigenous-Latino/a or Indigenous-Latinx in the absence of more specific information. Code 6 description includes the statement, There is evidence, other than surname or birth surname (maiden name), that the person is Hispanic but he/she cannot be assigned to any of the categories 1-5. Assign code 03 (American Indian or Alaska Native) when described as First Nations. First Nations usually refers to Indigenous peoples for ethnic groups who are the original or earliest known inhabitants of an area. The term ‘First Nations’ can be applied to individuals, but technically refers only to those who have Indian status under Canadian law as part of a recognized community. Within Canada, the term First Nations is generally used for Indigenous peoples other than Inuit and Métis. Outside Canada, the term can refer to Indigenous Australians, U.S. tribes within the Pacific Northwest, as well as supporters of the Cascadian independence movement. |

20240036 | Update to Current Manual/Race: How is Race coded when stated as Hispanic and there is no other information? See Discussion. |
There appears to be discrepant information in the 2024 (and prior) SEER manual regarding race coding when the patient is described only as Hispanic/Latina. Page 78 tells us to Code as 01 (White) when: b. There is a statement that the patient is Hispanic or Latino(a) and no further information is available
However, in Appendix D, under "Other Race descriptions", there is a statement that "If no further information is available, code as 99 Unknown." The list includes "Hispanic." |
Assign code 01 (White) for Hispanic when there is no additional information. It is listed in the 2024 SEER Manual, Race Coding Instruction 6.b.i. and in Appendix D for code 01. We will remove Hispanic from the list in Appendix D under code 99 in the next version of the manual. |

20210054 | EOD 2018/EOD Primary Tumor/Tumor Size--Clinical--Prostate: How is Tumor Size--Clinical coded when there is an incidental finding of prostate cancer on prostatectomy for another reason? See Discussion. |
SEER*RSA states EOD Primary Tumor should be coded to 800 for an incidental finding of prostate cancer on prostatectomy for other reasons. The SEER Manual states to assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded to 800; however, the definition for Tumor Size--Clinical indicates clinical classification is composed only of diagnostic workup prior to treatment. If there is no clinical workup for an incidental finding of prostate cancer, code 000 does not seem appropriate (does not meet criteria for clinical classification). Code 999 seems more appropriate for incidental findings during surgery for other reasons. The SEER Manual does not provide this exception in the current instruction. |
Assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded 800 (No evidence of primary tumor). Code 000 indicates no tumor was found since there was no clinical workup to identify this incidentally found cancer. This is a special instruction for cases coded 800 in EOD Primary Tumor. Text fields can be used to record details. |

20220043 | First Course Treatment/Neoadjuvant Therapy--Melanoma: How are the three Neoadjuvant Therapy data items (Neoadjuvant Therapy, Neoadjuvant Therapy--Clinical Response, Neoadjuvant Therapy--Treatment Effect) coded when a patient is diagnosed with melanoma in the lymph nodes with no primary skin site identified? The physician gives immunotherapy as neoadjuvant therapy with planned and carried out surgical resection of involved lymph nodes following completion of immunotherapy. There is no "planned definitive surgical resection of the primary site" as no primary site was found, |
Assign code 0 to each of the three Neoadjuvant Therapy data items in this situation. We will add an example to the coding instructions for these data items in the next release of the manual. |

20081097 | DCO/Systemic Treatment, Surgery Sequence: How does SEER want systemic treatment/surgery sequence coded for a DCO case? | Assign code 0 [No systemic therapy and/or surgical treatment] as a default for DCO cases. |

20210030 | Primary site--Breast: Patient was diagnosed with invasive ductal carcinoma of the left breast. Site of mass is 2:00 to 3:00. What is the correct site code, C504 upper outer quadrant (UOQ) or C50.8 (overlapping)? |
Assign C504, UOQ, for a left breast primary mass at 2:00 to 3:00. See the illustration in the SEER Coding Guidelines for breast, https://seer.cancer.gov/manuals/2021/AppendixC/Coding_Guidelines_Breast_2021.pdf |

20130210 | Primary site--Heme & Lymphoid Neoplasms: Does Rule PH27 apply meaning that primary site is coded to C809 or would it be more appropriate to code to C269 GI Tract NOS since all disease involves the GI tract and this is more specific?
Extranodal lymphoma first diagnosed in the stomach (fundus and antrum) which upon further investigation also involved the small bowel (MALT Lymphoma) in the absence of lymph node findings. MD staged this IIE. Initial thought was Gastric, but PET/CT indicated abnormal uptake involving loop of distended small bowel in the pelvis. |
Assign C269 for Gastrointestinal tract, NOS. Apply Rule PH24, code to the organ when only an organ is involved. This rule can be used for NOS sites such as GI tract, NOS.
Based on the information provided, this lymphoma is confined to the GI tract -- stomach and small bowel. |

20180016 | Primary site--Pancreas: Is the uncinate process of the pancreas coded to C259, C250, or C257? |
Assign C250 to the uncinate process of the pancreas. The uncinate process is part of the head of the pancreas. |

20210051 | Primary site/Biliary tract--Ampulla of Vater: What is the correct primary site code for intra-ampullary and periampullary adenocarcinoma, C241 (8144/3) or C249? See Discussion. |
Ampulla, biopsy: High grade dysplasia with focal intramucosal carcinoma in a background of ulceration with acute and chronic inflammation. Surgery pathology: Head of pancreas, duodenum, and distal stomach, pancreaticoduodenectomy-Ampulla, Adenocarcinoma, intestinal type, intra-ampullary and peri-ampullary (mixed type). Grade moderately differentiated, 1.5cm. Tumor invades into duodenal submucosa. Lymphovascular Invasion: Foci suspicious for lymphovascular invasion identified. Perineural Invasion: Present. Synoptic report: Tumor Site Intra-ampullary and peri-ampullary (mixed type). Histologic Type Adenocarcinoma, intestinal type. There is not enough information regarding site in radiology reports or operative report. CT-A/P/C:The patient's known ampullary mass is not well visualized on this exam. No significant intrahepatic or extrahepatic biliary ductal dilation is identified. The pancreatic duct is normal caliber. |
Assign C241. Ampulla (C241) includes both periampullary and intra-ampullary. |
