20210038 | Update to current manual/First course treatment--Neoadjuvant treatment: How are the 2021 neoadjuvant therapy fields coded when neoadjuvant therapy and surgery were part of first course plans but treatment was never completed. See Discussion. |
Example: Breast case where first course treatment plan is neoadjuvant therapy and surgery after. The patient was hospitalized during neoadjuvant therapy, elected hospice, and later died, so the neoadjuvant therapy was never completed, surgery not done. How are the 2021 neoadjuvant therapy fields coded in this situation as neoadjuvant therapy and surgery were part of first course plans. I coded neoadjuvant therapy to 2 - started but not completed, but there are no codes to properly explain the clinical response and therapy treatment effect as the patient did not complete neoadjuvant therapy. Should I use code 9 for clinical response and treatment effect or should this be left blank for this particular case? |
Assign code 8 for Neoadjuvant Therapy--Clinical Response in this case. We will update the SEER manual to allow code 2, in addition to code 1, in Neoadjuvant therapy when Clinical Response is coded 8. We will also add instructions covering a case such as this one. Assign code 7 for Neoadjuvant Therapy--Treatment Effect and use text fields to record the details. We will add instructions to the manual for this scenario. |

20210065 | Solid Tumor Rules (2018/2021)/Histology--Lung: Should there be an exception to the Solid Tumor Rules for Lung to allow coding a more specific histology described by ambiguous terminology, when the only pathologic workup done is a cytology report? Due to the unique nature of lung cases which are often diagnosed on imaging and cytology without more definitive pathology, we are seeing many cases where the existing Solid Tumor guidelines result in very generic NOS histology codes. For example, lung mass found on imaging with a fine needle aspirate of a lymph node, final diagnosis "positive for malignancy" and comment "consistent with squamous cell carcinoma." See Discussion. |
The Solid Tumor histology coding guideline #3 for Lung states that an ambiguous histology can only be coded over an NOS when a physician clinically confirms it or the patient receives treatment based on the ambiguous histology; similar instructions exist in rules H3 and H12. We are in a central registry and don't typically have access to physician notes or treatment plans; unfortunately our hospital abstracts rarely document physician confirmation of ambiguous histology and we are uncertain if we should accept their coding of the more specific histology, assuming they did find clinical confirmation that was not documented. If not, our understanding of the Solid Tumor rules is that the histology in such a case would have to be coded as malignancy NOS (8000/3) per the non-ambiguous final diagnosis, and that we cannot use the more specific but ambiguous squamous cell carcinoma since we don't have definite clinical confirmation. We also have a fair number of cytology-only lung cases without any hospital information to clinically confirm an ambiguous histology. |
Code histology as squamous cell carcinoma, NOS (8070/3) using Lung Solid Tumor Rules, Rule H3 if no other information is available. Rule H3 states: If the case is accessioned (added to your database) based on a single histology described by ambiguous terminology and no other histology information is available/documented, code that histology. |

20210075 | Reportability: What American College of Radiology Reporting and Data Systems (RADS) can be used to determine reportability? See Discussion. |
LI-RADS (liver), PI-RADS (prostate), and TI-RADS (thyroid) can be used to determine reportability. BI-RADS (breast) and Lung-RADS cannot be used to determine reportability. Can these systems below to determine reportability? C-RADS (from CT colonography) NI-RADS (head & neck) O-RADS (ovarian-adnexal) |
The following cancer cases are reportable unless there is information to the contrary. –Liver cases with an LI-RADS category LR-4 (reportable since 2021) or LR-5 (reportable since 2016) –Prostate cases with a PI-RADS category 4 or 5 (reportable since 2017) The following are not reportable without additional information. –Breast cases designated BI-RADS 4, 4A, 4B, 4C or BI-RADS 5 –Lung cases designated Lung-RADS 4A," 4B, or 4X –Liver cases based only on an LI-RADS category of LR-3 –Colon cases with only C-RADS information (C-RADS category C4 is not reportable by itself) –Head and Neck cases with only NI-RADS information (NI-RADS category 3 is not reportable by itself) –Ovarian or fallopian tube cases with only O-RADS information (none of the O-RADS categories are reportable without additional information) –Thyroid cases with only TI-RADS information (none of the TI-RADS categories are reportable without additional information) |

20210024 | Primary Site--Vulva: What is the primary site of patient with an excision of a left vulvar cystic mass showing focal mammary-type ductal carcinoma in situ (DCIS) on 11/06/2020? See Discussion. |
Final Pathologic Diagnosis: Vulvar cyst, excision: Focal mammary-type ductal carcinoma in situ, intermediate grade, arising within cystically dilated duct (See Comment) Size of DCIS: 0.7 CM. Margins: Negative. Comment Sections demonstrate a cystically dilated duct. Focally, at the periphery of the duct, there is a neoplastic monomorphic proliferation of ductal cells with intermediate grade nuclei. No associated necrosis is identified. Immunostains for GATA-3 and estrogen receptor are strongly positive within the neoplastic cells, supporting origin from mammary-like epithelium. Immunostain for p63 demonstrates preservation of a basal layer around the dilated duct, including the region involved by DCIS. Immunostain for cytokeratin 5/6 shows loss of expression within the DCIS. No stromal invasion is identified. The cyst appears to be completely excised. 12/01/2020 post op visit with surgeon: Ductal carcinoma in situ (DCIS) of the left vulva in an excised cystic lesion. PLAN: I reviewed the pathologic findings from the excision of the left vulvar cyst. This appears to be a cystic lesion in the mammary line with focal DCIS. It was excised completely with negative margins. It would not warrant any additional treatment except expectant management. |
Code the primary site to vulva. Use text fields to record the details. According to the WHO classification, several types of primary vulvar mammary-like carcinoma have been reported. It is rare and is thought to arise from specialized anogenital mammary-like glands within the vulva. It does not arise from ectopic breast tissue and is does not represent metastatic breast carcinoma. |

20210055 | Tumor Size--Pathologic/EOD 2018: How is Tumor Size--Pathologic coded when Extent of Disease (EOD) Primary Tumor is 800 (No evidence of primary tumor) and there has been no surgery to the primary site? See Discussion. |
The SEER Manual states to assign Tumor Size--Pathological code 000 when EOD Primary Tumor is coded to 800 (No evidence of primary tumor) for any schema. However, the definition of Tumor Size--Pathologic states that it records the size of a solid primary tumor that has been resected. If the primary site has not been resected (does not meet the pathologic staging criteria), then it seems that Tumor Size Pathologic should be 999 when EOD Primary Tumor is coded as 800. |
Assign code 999 for Tumor Size--Pathologic when there is no surgery of the primary site. Code 999 includes "No excisional biopsy or tumor resection done." |

20210066 | 2021 SEER Manual/Surgery of Primary Site--Lung: What is the correct surgery code for a left upper lobe (LUL) wedge resection (confirming adenocarcinoma) followed by a lingular-sparing LUL lobectomy and mediastinal lymph node dissection? Is the correct Surgery Code 22 since the lingula was not resected (not the whole LUL Lung)? Or should the appropriate surgery code be 33 (this surgery suffices to code to a lobectomy with the mediastinal lymph node dissection)? |
Assign code 22 for LUL wedge resection followed by a lingular-sparing LUL lobectomy and mediastinal lymph node dissection. Code the lymph node surgery in Scope of Regional Lymph Node Surgery. We obtained input from an expert who agrees with this code. He states a lingula-sparing lobectomy is best coded as a segmentectomy because it is the same as an apical trisegmentectomy. |

20210044 | Diagnostic Confirmation--Heme & Lymphoid Neoplasms--Plasma Cell Myeloma: Can serum protein electrophoresis (SPEP) be used as a definitive diagnostic method in the absence of a bone marrow biopsy? Is it appropriate to assign code 5 (Positive laboratory test/marker study) if there is no histological confirmation? See Discussion. |
Patient was diagnosed with lambda myeloma based on the M spike found on serum protein electrophoresis. A bone marrow biopsy was performed, but it was an insufficient sample. SPEP is not listed in the Hematopoietic Database as a lab test that can be used as a definitive diagnostic method. Since the physician did base the diagnosis on the SPEP result, would it be appropriate to assign code 5 (Positive laboratory test/marker study) since there was no histological confirmation? Under code 5, the Hematopoietic Manual states: Laboratory tests are listed under Definitive Diagnostic Methods in the Hematopoietic Database. |
Assign code 5 in Diagnostic Confirmation. We consulted with an expert hematopathologist who stated that SPEP would qualify for a diagnostic confirmation code of 5. He also stated that normally a SPEP is followed by a bone marrow biopsy. SPEP has been added to the Definitive Diagnostic Methods for plasma cell myeloma (9732/3). |

20210071 | Solid Tumor Rules (2018/2021)/Histology--Breast: How is histology coded for a diagnosis of invasive mammary neuroendocrine tumor (NET), grade 2/3? See Discussion. |
Table 3 (Breast Equivalent Terms and Definitions) lists “Neuroendocrine tumor, well-differentiated” of the breast as histology 8246/3. There is no entry for a grade 2 neuroendocrine tumor of the breast in Table 3. The pathologist did not indicate the neuroendocrine tumor was poorly differentiated (or it would otherwise be a small cell carcinoma). The pathologist noted “By current WHO criteria, this tumor is characteristic of a mammary neuroendocrine tumor, grade 2. These invasive tumors have similar prognostic and predictive features of invasive ductal carcinoma of the same grade and stage.” |
Assign code 8249/3, neuroendocrine tumor, grade 2 based on the pathologist statement of mammary neuroendocrine tumor grade 2. According to WHO Classification of Tumors of the Breast, 5th edition, neuroendocrine tumor (NET) is an invasive tumor characterized by low/intermediate grade. If the histology term is not listed in the Solid Tumor rules, the instructions state to also check ICD-O and updates. Per ICD-O, NET, grade 2 is coded 8249/3. Breast Table 3 will be updated for 2023. |

20210017 | Update to current manual/Mets at diagnosis fields--Lymphoma: Are distant metastases possible for a lymphoma with a primary site of lymph nodes? The instructions in the SEER manual tell us to assign code 8 in each of the Mets at Dx fields for a lymphoma originating in lymph nodes. |
This is a correction to the SEER manual. Lymphomas originating in lymph nodes (C77) could have distant metastases to any site except lymph nodes. The following corrections to the manual apply now and will appear in the next version of the manual. Remove C770-C779 from the instruction for assigning code 8 on the following pages. Page 135 Mets at Dx--Bone Page 137 Mets at Dx--Brain Page 139 Mets at Dx--Liver Page 141 Mets at Dx--Lung Page 145 Mets at Dx--Other Example Biopsy of axillary lymph node: Diffuse Large B-Cell lymphoma. Lymph nodes involved above and below the diaphragm, multiple nodules seen in lung, lesions in liver. Bone marrow biopsy positive for DLBLC. Per Hematopoietic manual, primary site would be C778 for multiple lymph node regions involved. Mets at Dx--Bone-0 Mets at Dx--Brain-0 Mets at Dx--Liver-1 Mets at Dx--Lung-1 Mets at Dx--Distant Lymph Nodes-8 Mets at Dx--Other-1 |
