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. |

20230069 | First Course Treatment/Immunotherapy--Colon: Is infliximab cancer directed treatment? See Discussion. |
While SEER*Rx does indicate infliximab should be coded as biological response modifier (BRM)/Immunotherapy, the manufacturer website for this medication indicates it is given for: Crohn’s disease, ulcerative colitis, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis. In addition, SEER*Rx does not indicate which primary sites this treatment may be given for. If it is indeed cancer directed treatment, can the typical primary sites be added for clarity? Case example: Patient is diagnosed with colorectal cancer and also has an existing diagnosis of Crohn’s disease; received surgery and FOLFOX6, as well as infliximab. There was no statement of what disease the infliximab was given to treat. |
infliximab is not cancer-directed treatment. This drug was last updated by the FDA 2/22/2023 with additional information on its approval to treat non-malignant neoplasms. To date, the FDA has not approved it for use in colon cancer. This drug was intially developed to treat colon cancer; however, found to be ineffective treating cancer. |

20230059 | Histology--Heme and Lymphoid Neoplasms: How is histology coded for a diagnosis stated as MDS/AML (myelodysplastic syndrome/acute myeloid leukemia) per the international consensus classification (ICC)? See Discussion. |
The final diagnosis on bone marrow biopsy was high grade myeloid stem cell neoplasm, 17% blasts by differential count. The pathologist further states that this could be classified as “MDS with increased blasts (MDS-IB2) per the WHO 5th edition classification, or MDS/AML per the international consensus classification (ICC).” FISH and cytogenetics revealed a loss of 7q, but no other AML-related genetic abnormalities. The physician confirms the patient has MDS/AML. |
Code histology as myelodysplastic neoplasm with increased blasts (9983/3) based on the WHO Classification of Hematolymphoid Tumors, 5th edition, Beta version 2. WHO lists MDS with increased blasts-2 (MDS-IB2) as a subtype of 9983/3. When differences exist between WHO and ICC, assign the histology based on the WHO Classification. |

20230009 | Solid Tumor Rules/Multiple Primaries--Vulva: How many primaries are accessioned when a 2023 diagnosis of keratinizing squamous cell carcinoma (SCC) (8071/3) of the vulva follows a previous diagnosis of nonkeratinizing SCC (8072/3) of the vulva and the timing rule (M12) does not apply? See Discussion. |
Table 19: Vulva Histologies of the Other Sites Solid Tumor Rules does not include entries for either keratinizing or nonkeratinizing squamous cell carcinoma in the “Squamous cell carcinoma, NOS” row. However, these are two distinctly different histologies per the ICD-O-3.2. All other Solid Tumor Rules schemas include an M Rule instructing one to abstract multiple primaries when separate/non-contiguous tumors are two or more different subtypes/variants in Column 3 of the Specific Histologies, NOS, and Subtype/Variants Table for the schema (e.g., Rule M6 for Lung). The timing of these tumors is stated to be irrelevant. The Notes confirm the tumors may be subtypes/variants of the same or different NOS histologies and tumors in column 3 are all distinctly different histologies (even if they are in the same row). However, the 2023 Other Sites schema appears to be missing this rule. Should these distinctly different histologies be accessioned as separate primaries? Is an M Rule missing from the Other Sites schema to address distinctly different histologies? |
Table 19 is based on WHO 5th Ed Tumors of vulva and squamous cell variants, keratinizing and non-keratinizing, are no longer recommended and are excluded from the 5th Ed. HPV related terminology is now preferred for these neoplasms. Per consultation with our GYN expert pathologist, based on the information provided, this is likely a single tumor that was not completely excised in the original biopsy. A new tumor in the same site would not appear within 8 months. If you cannot confirm two separate/non-contiguous tumors were present, abstract a single primary per M1. As for histology, the tumor showed both keratinizing and non-keratinizing features and HPV status is unclear. Per our expert, code to SCC 8070/3—keratinization or lack of does not change treatment or prognosis. Even If there is proof of separate/non-contiguous tumors, our expert still feels this is a single primary coded to SCC 8070/3. Treatment does not differ by keratinization or HPV status. Coding two primaries would be incorrect and inflate incidence rates. Per our expert, this is an unusual occurrence. The rules cover 85% of cases but there will always be situations that do not fit a rule. This case is an example of that. A new GYN specific Solid Tumor Rules module is under development and a rule to address this situation could be included. |

20230078 | Primary Site/Heme & Lymphoid Neoplasms--CLL/SLL: Should the primary site be coded C421 (bone marrow) for a diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) when the managing physician provides a Rai stage? See Discussion. |
The patient has adenopathy and a lymph node biopsy proved CLL/SLL. The patient underwent a peripheral blood smear, but the final diagnosis only indicated there is an abnormal CLL panel, positive for monoallelic or biallelic deletion of 13q. The pathologist noted a CLL related clone was detected, but there was no definitive diagnosis of CLL on the peripheral blood. No bone marrow biopsy was performed. However, the managing physician noted this was Rai Stage I CLL/SLL with adenopathy in the neck. The SSDI Manual notes, “Rai stage is only applicable for CLL, in which the bone marrow and/or peripheral blood are involved (primary site C421 for bone marrow, see Hematopoietic Manual, Module 3: PH 5, 6).” Should primary site default to C421 if the physician provides a Rai Stage in the absence of definitive peripheral blood or bone marrow involvement documented in the medical record? |
Assign primary site C421. The Site-Specific Data item (SSDI) Manual, Rai Classification section, states: Per confirmation from medical oncologists, Rai stage is only recorded for patients who have bone marrow and/or peripheral blood involvement. Per the Hematopoietic Rules, primary site would be C421 (See Hematopoietic Manual, Module 3: Rules PH 5, 6). A new code has been added to the 5 SSDIs (code 5) to use when primary site is not C421. |

20230013 | Reportability/Histology--Skin: Is dermatofibrosarcoma protuberans (DFSP) with fibrosarcomatous overgrowth, DFSP with fibrosarcomatous component Grade 2, or DFSP with focal myxoid features (2022) reportable for 2021-2022 diagnoses? |
Yes. DFSP with fibrosarcomatous overgrowth and DFSP with fibrosarcomatous component Grade 2 are synonymous with fibrosarcomatous DFSP (8832/3). Our expert pathologist also advises that DFSP with focal myxoid features is the same as DFSP, myxoid (8832/3). |

20240008 | Solid Tumor Rules/Histology--Brain and CNS: Should the term “diffuse” be added to Note 2 in the Non-Malignant Central Nervous System (CNS) Solid Tumor Rules, Table 6: Specific Histologies, NOS, and Subtypes/Variants, for the papillary glioneuronal tumor 9509/1? See Discussion. |
Should Note 2 state, "Beginning with cases diagnosed 1/1/2023 forward, diffuse leptomeningeal glioneuronal tumor is coded 9509/3? See the Malignant CNS rules." Currently the Note only states, "leptomeningeal glioneuronal tumor," but the histology that changed behavior is listed in both Table 6, Column 1 (Non-Malignant CNS) and Table 3 (Malignant CNS) as, "Diffuse leptomeningeal glioneuronal tumor." |
The correct term is diffuse leptomeningeal glioneuronal tumor listed as a synonym in Column 2. We will add the term diffuse in Note 2, Column 1 with the 2025 updates. In the meantime, you can add "diffuse" to your pdf version until the update is published. |

20240019 | Solid Tumor Rules/Histology--Head and Neck, Other Sites: Do human papilloma virus (HPV) histologies that occur with subtype/variants of squamous cell carcinoma (SCC) in various sites apply only to sites in Solid Tumor Rules, Head and Neck, Table 5 and Other Sites, Table 23? See Discussion. |
The 2024 Solid Tumor Rules, Table 5: Tumors of the Oropharynx, Base of Tongue, Tonsils, Adenoids contain notes that say beginning 1/1/2022, keratinizing or non-keratinizing SCCs, HPV positive or HPV negative, are coded 8085 or 8086, respectively, for sites listed in the Head and Neck Solid Tumor Rules, Table 5 only. Table 5 introductory section also states for cases diagnosed 1/1/2023 forward: “When the diagnosis is a subtype/variant of squamous cell carcinoma and HPV status is also noted, code the subtype/variant.” This latter instruction is also included in Other Sites Table 23 (Penis and Scrotum Histologies) as a “Penis Coding Note.” Do these instructions ONLY apply to sites on those tables (and only to Penis or to Scrotum also in Table 23)? How should we code HPV-related keratinizing/non-keratinizing or other subtype/variant SCCs, for sites NOT on those tables, given the fact that only the more common histologies are listed in the Solid Tumor tables? For example, we recently reviewed a case with HPV-positive basaloid squamous cell carcinoma of the anus (C21.0). |
Code the specific histology as stated by the pathologist according to the site-specific instructions in the Solid Tumor Rules. When the histology provides a subtype/variant in addition to the HPV histology codes, code the subtype/variant as it is important to capture this histology as in the example provided. the instruction to code the subtype/variant over 8085 or 8086 applies to the following sites: oropharynx, cervix, vagina, vulva, anus, and penis. A note will be added indicatng this in 2025. Per 2024 Cancer PathCHART expert pathologist review, morphology codes 8085/3 and/or 8086/3 are valid and applicable to head and neck, oropharynx, cervix, vagina, vulva, fallopian tube, anus, and penis (reference: Cancer PathCHART: Product Downloads and Timelines). Other coding resources will be updated to reflect these changes in 2025. |

20240023 | Solid Tumor Rules/Histology--Penis: Why is warty carcinoma listed in Other Sites, Table 23 (Penis and Scrotum Histologies) as 8051 when the ICD-O-3.2 and SINQ 20200003 indicate the correct histology is 8054 for this neoplasm? See Discussion. |
The ICD-O-3.2 indicates histology 8051 only applies to diagnoses of condylomatous carcinoma and warty carcinoma made prior to 2018. For penis cases diagnosed 2018 and later, these neoplasms should be coded as 8054. This is consistent with SINQ 20200003. However, a new Table was added to the Other Sites schema in the 2024 Solid Tumor Rules update. Table 23 lists “Verrucous carcinoma / carcinoma cuniculatum / Warty carcinoma” as histology 8051. While verrucous carcinoma is still listed under histology 8051 in the ICD-O-3.2, warty carcinoma is not. Does Table 23 need to be updated? Or is this an error in both the ICD-O-3.2 and SINQ 20200003? |
Assign histology code 8054/3 for warty carcinoma. Assign 8051/3 for verrucous carcinoma and carcinoma cuniulatum. The WHO Classification of Urinary and Male Genital Tumors, 5th edition (2022) revised the terminology for squamous cell carcinoma groupings from "non-HPV-related" to "HPV-independent" and from "HPV-related to "HPV-associated". Warty carcinoma is defined as a "morphologically distinct HPV-associated verruciform neoplasm that shares histological features with a giant condyloma but has definitive cytological atypia and a malignant infiltrative architecture." Verrucous carcinoma (including carcinoma cuniculatum) is defined as an HPV-independent squamous cell carcinoma, and is correctly coded to 8051/3. The 2024 Solid Tumor Rules, Table 23, Penis and Scrotum Histologies will be updated to reflect this revised terminology and coding. |

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. |
