20190065 | Update to current manual/EOD 2018/Summary Stage 2018--CLL/SLL: Can chronic lymphocytic leukemia (CLL) be staged when diagnosed by peripheral blood and no bone marrow biopsy, and observation is employed? See Discussion. |
The physicians do not use the Lugano system as we are instructed to stage chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) as lymphomas. I had always been instructed that this qualifies as "bone marrow involvement," or "diffuse disease," and therefore is a Stage IV. Our experts advise that there is not enough information to code it to bone marrow, but do not elaborate as to whether you can actually code Extent of Disease (EOD), SEER Summary Stage, and AJCC Staging? |
For EOD and Summary Stage: Peripheral blood involvement for CLL (or any lymphoma-but most commonly for CLL) can be coded. This is code 800 for 2018 EOD Primary Tumor, and code 7 for Summary Stage 2018. We have recently received confirmation that peripheral blood involvement only is not enough information to assign AJCC stage; assign code 99 for AJCC Stage Group. We will correct in the 2021 release of EOD so that peripheral blood involvement only will have its own code to derive the appropriate AJCC TNM Stage Group (99). |

20230062 | Update to current manual/EOD 2018/EOD Primary Tumor--Appendix: Is it correct to code Extent of Disease (EOD) Primary Tumor as code 500 (Invasion of/through serosa (mesothelium) (visceral peritoneum)) and EOD Mets as code 30 (Intraperitoneal metastasis (peritoneal carcinomatosis) WITH or WITHOUT peritoneal mucinous deposits containing tumor cells), when the resection pathology report for a low-grade appendiceal mucinous neoplasm (LAMN) proves “Tumor Extent: Acellular mucin invades visceral peritoneum (serosa)” as well as metastatic LAMN within the right lower quadrant peritoneum? See Discussion. |
This patient had serosal involvement and the pathologist and managing physician staged this as pT4a disease. This extension seems best captured by EOD Primary Tumor code 500. Additionally, the patient had discontinuous metastatic involvement of the peritoneum, and this was staged by the pathologist and managing physician as pM1b (Intraperitoneal metastasis only, including peritoneal mucinous deposits containing tumor cells). Although this peritoneal involvement was present in the right lower quadrant, it was staged as distant metastatic disease and not as part of the primary tumor category. However, currently EOD Primary Tumor code 600 would seem to apply since the peritoneal tumor was in the right lower quadrant. Code 600 is defined as mucinous tumors with peritoneal involvement confined within right lower quadrant. This EOD Primary Tumor code and the physician’s M category assignment do not align; the physician has staged this as distant metastasis (M category, not the T category). Should the peritoneal metastasis (even limited to the right lower quadrant) be included in the EOD Mets field and not in the EOD Primary Tumor field? In other words, should the peritoneal involvement included in EOD Primary Tumor code 600 be reclassified in EOD Mets code 30 (Intraperitoneal metastasis (peritoneal carcinomatosis) WITH or WITHOUT peritoneal mucinous deposits containing tumor cells)? |
Assign code 500 for EOD Primary Tumor and code 30 for EOD Mets. This will correctly derive the T4aM1b stage based on AJCC 8th edition. Abstraction of peritoneal metastasis changed from the T category in the AJCC 7th edition to the M category in the 8th and 9th AJCC editions. As a result, for cases diagnosed in 2018 and later, peritoneal deposits in the right lower quadrant should be abstracted as EOD Primary Tumor code 500 and EOD Mets code 30. However, the EOD Primary Tumor code of 600 has not yet been updated to align with the 8th and 9th AJCC editions. The 2025 updates will correct for this via a conversion for cases diagnosed in 2018 and forward where EOD Primary Tumor = 600 and EOD Mets = 00 or 10 to EOD Primary Tumor = 500 and EOD Mets = 30. Effective immediately, abstract peritoneal deposits in the right lower quadrant as EOD Primary Tumor code 500 and EOD Mets code 30, even though you will still have the ability to assign EOD Primary Tumor code 600 in your abstraction software until the 2025 updates are deployed. |

20190015 | Update to current manual/EOD 2018--EOD Primary Tumor: Should Note 6 in Extent of Disease (EOD) Primary Tumor for the schemas Fallopian Tube, Ovary, and Primary Peritoneal Carcinoma be revised to exclude pelvic sites? See Discussion. |
There is a discrepancy between Notes 3 and 6 in the schemas Fallopian Tube, Ovary, and Primary Peritoneal Carcinoma for EOD Primary Tumor. Note 3 describes extension/discontinuous metastasis to the pelvic sites (code 450) and includes the sigmoid colon, rectosigmoid and rectum since these are all pelvic sites. However, Note 6 also includes rectosigmoid and sigmoid colon. Note 6 is describing extension/discontinuous metastasis to the abdominal sites (600-750), so it should include rectosigmoid or sigmoid colon (since those are pelvic sites). Note 6 indicates, Intestine, large (except rectum). In the previous Collaborative Stage, the corresponding note used to also include: except sigmoid colon, rectosigmoid and rectum. Did sigmoid colon and rectosigmoid get removed from the list here? That is, should Note 6 read, Intestine, large (except sigmoid colon, rectosigmoid, rectum)? Involvement of the sigmoid, rectosigmoid, or rectum via peritoneal seeding/metastasis is consistent with T2b disease and would correlate with code 450 (pelvic sites), not codes 600-750 (abdominal sites). Those codes only correlate with T3 and greater disease (i.e., peritoneal seeding/metastasis of the abdomen). |
Thank you for bringing this issue to our attention. Rectosigmoid and Sigmoid Colon belong in Note 3 and not Note 6 for the following EOD schemas: Fallopian Tube, Ovary, and Primary Peritoneal Carcinoma. Rectosigmoid and sigmoid colon will be removed as separate listings from Note 6. The only mention in Note 6 will be: Intestine, large (except rectum, rectosigmoid, and sigmoid colon) This change will be made for the next update. |

20230049 | Update to Current Manual/Surgery of Primary Site 2023--Skin: Regarding the 2023 skin surgery codes for punch biopsy NOS (B220) and shave biopsy NOS (B230), how is Date of First Surgical Procedure coded for cutaneous lymphoma and Kaposi sarcoma when the punch or shave biopsy is not excisional? See Discussion. |
Now that there are specific surgery codes for shave and punch biopsies, are these biopsies always the Date of First Surgical Procedure (NAACCR Item #1200)? Or should we still be applying the Surgery of Primary Site 2023 instruction in the SEER Manual that states shave or punch biopsies are most often diagnostic; code as a surgical procedure only when the entire tumor is removed and margins are free/gross disease is removed? We are aware of the instruction for melanoma cases outlined in SINQ 20230034; however, it is unclear if this should also apply to cutaneous lymphomas and Kaposi sarcomas, or if the intent of the procedure is used for these specific types of skin cases that typically present with multifocal involvement. Example 1: Patient is diagnosed March 2023 with primary cutaneous T-cell lymphoma presenting as pink, tan patches on the trunk. Punch biopsy diagnosed CTCL and treatment was given via narrow band UVB phototherapy. Example 2: Patient is diagnosed February 2023 with Kaposi sarcoma presenting as widespread violaceous macules, papules, plaques on the torso, bilateral extremities, and abdomen. Punch biopsy diagnosed Kaposi sarcoma. |
Code the Date of First Surgical Procedure (NAACCR Item #1200) as the date the shave, punch, or elliptical biopsy was performed. This instruction applies to cutaneous lymphoma and Kaposi sarcoma as well. Beginning with cases diagnosed 2023 and after, shave, punch, or elliptical biopsies are coded as a surgical procedure regardless of margin status. The instruction in the 2023 SEER Manual that states "shave or punch biopsies are most often diagnostic; code as a surgical procedure only when the entire tumor is removed and margins are free/gross disease is removed" has been deleted from the 2024 SEER Manual. Refer also to the Appendix C Coding Guidelines for Kaposi Sarcoma of All Sites and Lymphoma for coding primary site. |

20230034 | Update to Current Manual/Surgery of Primary Site 2023--Melanoma: Considering the 2023 melanoma surgery codes for punch biopsy NOS (B220) and shave biopsy NOS (B230), how is Date of First Surgical Procedure coded when the punch or shave biopsy is not excisional? See Discussion. |
Now that there are specific surgery codes for shave and punch biopsies, are these biopsies always the Date of First Surgical Procedure (NAACCR Item #1200)? Or should we still be applying the Surgery of Primary Site 2023 instruction in the SEER Manual that states shave or punch biopsies are most often diagnostic; code as a surgical procedure only when the entire tumor is removed and margins are free/gross disease is removed? Example: On 01/01/2023, patient has a frontal scalp shave biopsy showing melanoma, margins involved. On 02/01/2023, frontal scalp excision shows residual melanoma. Surgery code is assigned B520 (shave followed by wide excision). How is Date of First Surgical Procedure coded now that there is an additional surgery code for the shave biopsy? |
Code the Date of First Surgical Procedure as 01/01/2023 in the example provided where the shave biopsy is followed by wide excision. Beginning in 2023, significant changes were made in that shave, punch, and elliptical biopsies are coded as surgical procedure regardless of margin status. Appendix C Skin Surgery Codes state that an incisional biopsy would be a needle or core biopsy of the primary tumor. Please see Appendix M: Case Studies for Coding Melanoma in STORE v23, Case study 2: Shave Biopsy followed by WLE (page 412), for an explicit example of how to code your example case. We will clarify this in the upcoming release of the SEER manual, |

20220024 | Update to Current Manual/Residence at diagnosis: Would an exchange student be a temporary resident of the SEER area or a non-resident? See Discussion. |
A 17 year old exchange student was brought into the hospital with appendicitis. The patient had an appendectomy; there was no follow up treatment. 5/27/2006 pathology report of vermiform appendix: Adenocarcinoid appendix <5 mm tumor limited to appendix. The patient has no record in Lexis Nexus and no social security number. The address is a post office box; additionally, the patient’s birthplace is Switzerland and is lost to follow up. |
Code the residence where the student is living for exchange students temporarily living in the U.S. Code the temporary address if known or the Post Office Box if unknown. We will add this scenario to the next release of the SEER manual. |

20240026 | Update to Current Manual/Reportability--Pancreas: For cases diagnosed 2024+, is a diagnosis of pancreatic intraepithelial neoplasia II (PanIN II) reportable? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual: Reportability – Reportable Diagnosis List indicates pancreatic intraepithelial neoplasia (PanIN II) (C250-C259) is reportable. However, the ICD-O-3.2 lists “Glandular intraepithelial neoplasia, grade II” and “Glandular intraepithelial neoplasia, low grade” as histology code 8148 with behavior of /0 (benign). |
Do not report PanIN II. WHO Classification of Digestive Tumors, 5th edition, now categorizes PanIN into two categories, low grade (8148/0) and high grade (8148/2). PanIN grade I and PanIN grade II are categorized as PanIN low grade; PanIN grade III is categorized as PanIN high grade. We will update the Reportability section of the manual. |

20240032 | Update to Current Manual/Reportability--Biliary Tract: Is a diagnosis of high grade dysplasia of the gallbladder reportable? See Discussion. |
Patient was diagnosed March 2024 with high grade dysplasia of the gallbladder during excision for clinical history of acute cholecystitis and obstruction. Per the STR, Table 10 for Gallbladder and Extrahepatic Bile Duct Histologies shows Biliary intraepithelial neoplasia, high grade as code 8148/2. High grade glandular intraepithelial neoplasia of the biliary tract is also code 8148/2. Recent SINQ 20240021 (GI specific) indicates high grade dysplasia is reportable as high grade glandular intraepithelial neoplasia (8148/2) for stomach, small intestine, and esophagus. Does the same hold true for gallbladder? If so, then it appears there is a conflict between STR and Appendix E2. However, using the logic of SINQ 20240021 for this site would appear to contradict Appendix E2 which indicates high grade dysplasia in sites other than stomach, intestine, and esophageal sites is not reportable. If we can code high grade dysplasia of GI sites to 8148/2, should we accession high grade dysplasia of the gallbladder and other biliary sites in a similar manner? If so, then Appendix E needs to be modified. |
Report biliary intraepithelial neoplasia (dysplasia), high grade. As noted in SINQ 20240021 and the Other Sites Solid Tumor Rules, Rules H4/H26, the listed sites may not include all reportable neoplasms for 8148/2. We will update the Other Sites Solid Tumor Rules to reflect this code as well as make revisions in the next release of the SEER Manual. |

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. |

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. |
