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. |

20230051 | First Course Treatment/Surgical Margins of the Primary Site--Melanoma: Is margin status positive or negative when the lesion “approximates” margins? This was noted in the pathology report comment on a malignant melanoma in-situ shave biopsy. Follow-up with physicians is not possible in this situation. |
Assign margin status as “positive” when stated as approximates margins as recommended by our expert pathologists. Approximating means coming right up to inked margin without the margin transecting the tumor. |

20230071 | Solid Tumor Rules/Histology--Cervix: How is histology coded for a 2023 endocervical adenocarcinoma negative for high-risk human papilloma virus (HR-HPV) on Pap smear and strongly positive for p16 on biopsy? See Discussion. |
The Solid Tumor Rules indicate p16 is a valid test to determine HPV status and can be used to code HPV-associated/-independent. In this case, we do not know whether the HR-HPV test was done on cytologically malignant cells, or on benign cervical cells. It may be impossible to tell unless 100% of the cytology specimen is malignant, but we will not have access to that information. Also, HR-HPV testing is routine on Pap smears, so this testing does not mean the tumor cells specifically harbor HPV. |
Assign histology as adenocarcinoma, HPV-associated (8483/3) as designated in Table 17, Uterine Cervix Histologies, of the Other Sites Solid Tumor Rules. The WHO Classification of Female Genital Tumors, 5th edition, states that p16 immunohistochemistry is an effective (yet flawed) indirect test for HR-HPV infection, in line with the STRs that state p16 is a valid test to determine HPV status and can be used to code HPV-associated and HPV-independent histologies. In this scenario, "negative for high-risk human papilloma virus (HR-HPV) on Pap smear" would be cytology-based, and may have missed cytologically malignant cells. A subsequent, more definitive biopsy was performed and was found to be strongly positive for p16, therefore, the tumor should be coded as 8483/3. |

20230021 | Histology--Soft Tissue: How is histology coded for malignant neoplasm with neuroectodermal differentiation and TPR-NTRK1 gene rearrangement diagnosed on left shoulder excision? See Discussion. |
March 2022, left shoulder soft tissue mass excision shows a spindle cell tumor with outside consultation diagnosis of malignant neoplasm with neuroectodermal differentiation and TPR-NTRK1 gene rearrangement. Diagnosis comments indicate the findings most closely resemble the spectrum of kinase-rearranged mesenchymal neoplasms, such as lipofibromatosis-like neural tumor. However, the expression of SOX10 and mature melanocytic markers is unusual, and does not exclude melanocytic differentiation. Should this be classified as a peripheral neuroectodermal tumor (9364) or as an "NTRK-rearranged spindle cell neoplasm (emerging)" (8990) if there is a NTRK gene rearrangement? |
NTRK-rearranged spindle cell neoplasm is a newly identified variant of sarcoma; however, WHO has not yet proposed a specific ICD-O code for this rare neoplasm. Code to spindle cell sarcoma (8801/3). WHO defines NTRK-rearranged spindle cell neoplasm as an emerging group of molecularly defined rare soft tissue tumors that span a wide group of morphologies and histological grades, and are most often characterized by a spindle cell phenotype among other characteristics. |

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, |

20230020 | First Course Treatment/Reason for No Surgery of Primary Site: How should Reason for No Surgery of Primary Site be coded for cases when surgery was planned but aborted due to extent of disease seen during planned procedure? See Discussion. |
Lung abnormality on imaging prompted diagnosis on subsequent biopsy and clinical staging was documented as cT1b N0 M0. There was an attempt at resection, but the patient was found to have chest wall involvement and the procedure was aborted. How would Reason for No Surgery of Primary Site be coded in these types of scenarios when the surgery is aborted and the treatment plan changes due to the extension seen during surgery? |
For the example provided: For 2023 cases and forward, if no part of the surgery was performed, code Surgery of Primary Site 2023 (NAACCR Item #1291) as code A000 or B000 (no surgical procedure of the primary site). Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 2 (surgery of the primary site was not recommended/performed because it was contraindicated due to patient risk factors (comorbid conditions, advanced age, progression of tumor prior to planned surgery, etc.). In contrast, if any part of the surgery was performed, assign the Surgery of Primary Site 2023 (NAACCR Item #1291) code that best reflects the extent of the surgery performed. Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 0 (surgery of the primary site was performed). Use text fields to record the details. For cases prior to 2023, apply the same approach using Surgery of Primary Site (NAACCR Item #1290) instead of Surgery of Primary Site 2023 (NAACCR Item #1291). |

20240021 | Solid Tumor Rules/Reportability/Histology--Digestive Sites: Is a diagnosis of “high grade dysplasia” (not specified to be squamous or glandular) reportable for esophagus, stomach, and small intestine for cases diagnosed beginning in 2024? If so, how should histology be coded? See Discussion. |
SEER Program Coding and Staging Manual indicates high grade dysplasia of esophagus, stomach, and small intestine are reportable. The ICD-O-3.2 does not include “high grade dysplasia” as equivalent to “high grade squamous dysplasia.” If reportable, would high grade dysplasia (NOS) that originates in the stomach and small intestine default to 8148/2, while esophageal high grade dysplasia (NOS) default to 8077/2? |
Report these high grade dysplasia of the following organs as stated below. Stomach: Assign code 8148/2 glandular intraepithelial neoplasia, high grade using the Other Sites Solid Tumor Rules, Table 6: Stomach Histologies and as described in the WHO Classification of Digestive Tumors, 5th edition. Small intestine and Esophagus: Assign code 8148/2 glandular intraepithelial neoplasia, high grade, using the Other Sites Solid Tumor Rules, Other Sites Histology Rules, Rule H4/H26. The following note is listed for both of these rules. Note: This list may not include all reportable neoplasms for 8148/2. See SEER Program Coding and Staging Manual or STORE manual for reportable neoplasms The Other Sites Solid Tumor Rules, Table 5: Esophagus Histologies and Table 7: Small Intestine and Ampulla of Vater Histologies will be updated to reflect this code as time permits. |

20240011 | Solid Tumor Rules/Histology--Other Sites: Other Sites Table 2 (Mixed and Combination Codes) requires site designations; can sites be added? See Discussion. |
There are multiple possible entries (rows) for a tumor with a neuroendocrine component and non-neuroendocrine component, but these rows do not specify which primary sites are applicable. Row 1 (Combined small cell carcinoma, 8045) seems applicable to a prostate primary, but not to a GI primary since GI primaries are now generally referred to as MiNENs (mixed neuroendocrine non-neuroendocrine tumors), but Table 2 does not provide any instructions regarding how to determine the difference between 8045 and 8154 (or 8244). For SEER Workshop Case 03 (mixed prostate case), many users selected 8154 or 8244 as the mixed histology code per Table 2, but these histology codes are not listed as applicable in Table 3 (Prostate Histologies). Per the WHO Blue Books, these histologies are not listed as applicable to the prostate. How are registrars to determine the correct mixed code without site designations, especially if they don't have access to the WHO Blue Book or to a pathologist who may be able to clarify the codes? |
Sites may be added to certain combinations when indicated by ClinCORE review for Cancer PathCHART. Please note some sites were added in the 2024 update as a result of PathCHART review. A newly-formed Solid Tumor Editorial Board and its subgroups are currently working to evaluate the Solid Tumor Manual and make recommendations on ways to improve the structure and formatting of the manual and its content. Follow the rules and instructions in the Other Sites STRs when assigning combination histology codes. Histology Coding Rules Use the Histology Coding Rules when assigning combination codes. Coding Histology Information Use this section that includes the mixed histology (Table 2) and site-specific histology tables (Tables 3-23) for one or more histologies within a single tumor. Do not use this section in place of the Histology Coding Rules. While site-specific histology tables, based on current WHO Classification of Tumors books, have been added to Other Sites STRs, not all site groups have individual histology tables; coding may require the use of ICD-O and updates. The histology tables in Other Sites STRs include additional coding instructions and notes to assign the correct ICD-O code when appropriate. The tables are not meant to be all-inclusive; rather they are intended to address difficult coding situations to facilitate the assignment of the correct histology code. Table 2: Mixed and Combination Codes Instructions Once you have identified the histology terms and have been instructed to use Table 2 by the Histology Coding Rules, compare the terms in the diagnosis to the terms in Column 1. When the terms match, use the combination code listed in Column 2. Use adenocarcinoma mixed subtypes 8255 as a “last resort” code. |

20240025 | Update to the current manual/Reportability--Esophagus: Is high grade dysplasia of the esophagus reportable? The 2024 Seer Program Manual, page 21, has an example that states it is not reportable. See Discussion. |
Example 4: Esophageal biopsy with diagnosis of “focal areas suspicious for adenocarcinoma in situ.” Diagnosis on partial esophagectomy specimen “with foci of high grade dysplasia; no invasive carcinoma identified.” Do not accession the case. The esophagectomy proved that the suspicious biopsy result was false. Appendix E2 #32 of the SEER Manual states high grade dysplasia in site other than stomach, small intestines, and esophageal primary sites are not reportable. Does this mean high grade dysplasia is reportable for esophagus primaries? |
High grade dysplasia of the esophagus is reportable. The example will be corrected in the next edition of the SEER manual. |

20240024 | Reportability/Histology: Is angiomyxoma (this includes borderline or behavior code /1 cases) of the soft tissue reportable? Can you provide us with coding guidelines for angiomyxoma for when its reportable or not reportable? |
Do not report angiomyxoma. ICD-O-3.2 assigns 8841/0 to this benign tumor. This includes superficial and deep (aggressive) angiomyxoma. |
