20240068 | Solid Tumor Rules/Histology--Ovary: How is histology coded for an ovary case with a diagnosis of “high grade papillary serous carcinoma” in 2023? This term is not in the Solid Tumor Rules and ICD-O 3.2 updates. Is “high grade papillary serous carcinoma” equivalent to “high grade serous carcinoma” (8461) or to “papillary serous adenocarcinoma” (8441) with high grade captured only in the Grade fields, or is there another more appropriate code? |
Assign code 8461/3 for high-grade papillary serous carcinoma. |

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. |

20240050 | Solid Tumor Rules/Multiple Primaries--Vulva: Why is there no M Rule in the Other Sites Multiple Primary Rules related to extramammary Paget disease of the vulva? See Discussion. |
The only Other Sites H Rule related to extramammary Paget disease is included in the Multiple Tumors Abstracted as a Single Primary module. Rule H28 instructs one to code the histology of the underlying tumor when there is extramammary Paget disease and an underlying tumor of the anus, perianal region, or vulva. Therefore, a vulvar extramammary Paget disease with underlying adenocarcinoma is coded as adenocarcinoma (8140/3), and not extramammary Paget disease (8542/3). However, there is no M Rule confirming extramammary Paget disease and the underlying adenocarcinoma are a single primary (i.e., multiple tumors abstracted as a single primary) making it difficult for one to use the Multiple Tumors Abstracted as a Single Primary H rules module. We recognize this is a longstanding histology coding rule, but how are registrars supposed to arrive at Rule H28 when the M Rules must be applied first and do not instruct one to accession a single primary? Moreover, if this is to be a single primary (per rule M2), why is there no H Rule in the Single Tumor module? |
In sites other than breast (see Breast Solid Tumor Rules M8/M9), Paget disease with underlying invasive disease is a single primary and the underlying histology is coded. Primary Paget disease of the vulva is uncommon, and we cannot create rules for all possible situations in the Other Sites module. A GYN specific module is in development, and we will look into adding a Paget-related rule. It will differ because Paget in breast is a different situation while Paget in the vulva is always adenocarcinoma. Paget disease of the vulva is an in-situ adenocarcinoma of vulvar skin with or without an underlying adenocarcinoma (WHO Classification of Female Genital Tumors, 5th ed.). When there is a statement of “underlying” adenocarcinoma, it is a single primary as with Breast Solid Tumor Rule M8. |

20240055 | Update to the Current Manual/Tumor Size Summary—Neoadjuvant Treatment: Would you clarify instructions in the 2024 SEER Program Coding and Staging Manual (SPCSM) for Tumor Size Summary when a patient receives neoadjuvant treatment? There seems to be a conflict with the STORE Manual. See Discussion. |
Starting for cases diagnosed in 2024, the SPCSM manual no longer requires the data items for clinical and pathologic tumor size. Instead, it appears to align with the CoC data item of Tumor Size Summary. The two manuals contradict each other when it comes to coding tumor size summary for neoadjuvant chemotherapy (NAC) treated cancers. STORE states: "If neoadjuvant therapy followed by surgery, do not record the size from the pathologic specimen. Code the largest size of the tumor prior to neoadjuvant treatment; if unknown code size as 999." 2024 SPCSM states "If neoadjuvant therapy followed by surgery, do not record the size from the pathologic specimen. Code the largest size of the tumor prior to neoadjuvant treatment; if unknown code size as 999." It continues to state 12. Assign code 000 when…. (a) no residual tumor is found…(i) Neoadjuvant therapy has been administered and the resection shows no residual tumor & 14. Assign code 999 when...(d) Neoadjuvant therapy has been administered and resection was performed. Do not use a post-neoadjuvant size to code pathologic tumor size; however, you may use the clinical tumor size if available It seems that we will lose the value of the tumor size summary if we code 000 when NAC is administered and there is no residual disease. Example: Patient has a 90 mm triple positive breast tumor and is treated with neoadjuvant TCHP (docetaxel/carboplatin/ trastuzumab/pertuzumab). After completing neoadjuvant therapy, the patient has a mastectomy with no residual disease noted on the final pathology report. Using the 2024 SPCSM instructions, code 000 for Tumor Size Summary instead of 090 for the clinical tumor size of 90 mm tumor noted before NAC was administered. This has the potential to affect data analysis, research, and clinical trial accrual. |
When there is neoadjuvant therapy followed by surgery, do not record the size from the pathologic specimen. Code the largest size of the tumor prior to neoadjuvant treatment; if unknown code size as 999. We will remove Coding Instruction 12.a.i in the next version of the manual. |

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. |

20240018 | Solid Tumor Rules/Histology--Head and Neck, Other Sites: Please provide clarification about effective dates for using p16 testing to assign HPV-related histology codes for various primary sites. See Discussion. |
1. The 2022 and 2023 SEER Program Coding Manuals state under Histologic Type ICD-O-3: Beginning with cases diagnosed 01/01/2022 forward, p16 test results can be used to code squamous cell carcinoma, human papilloma virus (HPV) positive (8085) and squamous cell carcinoma, HPV negative (8086). NAACCR 2023 Implementation Guidelines contain similar instructions on HPV histologies for cervix, vulva and vagina that are applicable back to 2022 (2021 for cervix). The current Other Sites Solid Tumor Rules state on the Histology tables for anus, cervix, vagina, vulva, and penis and scrotum: "p16 is a valid test to determine HPV status and can be used to code HPV associated and HPV independent histologies." Since Other Sites Solid Tumor Rules apply to cases diagnosed 2023+, can p16 results only be used from 2023 onward, to code HPV-related histologies for primaries that fall under the Other Sites module? Or per the 2022 SEER Manual statement and NAACCR 2023 Implementation Guidelines, could a p16-confirmed HPV histology code also apply to a 2022 Other Sites case and if so, is that only for cervix, vulva, and vagina? Further complicating the matter are the 2024 ICD-O-3.2 update documents indicating these codes are valid 1/1/2024+ for the “Other Sites” penis and scrotum. 2. Is using p16 testing for HPV-related histology codes ONLY allowed for sites in the Solid Tumor tables that contain the statements about p16 (Head & Neck Table 5, and the Other Sites tables noted above for anus, cervix, etc.)? Or could it apply to primary sites outside of those tables; for example, a 2022 pathology report from the ethmoid sinus C311 indicating an HPV-related histology based on p16 testing? The ICD-O-3 Annotated Histology lists include C310-C313 among the common site codes for 8085 and 8086. The Head and Neck Solid Tumor Rules “New for 2022” section and rule H1 Note 4 also mention that p16 can be used to code HPV histologies; these sections would seem to apply to all sites in that module, since only the more common histology codes are listed in the tables and if not, we are instructed to use ICD-O. |
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 scrotum (reference: Cancer PathCHART: Product Downloads and Timelines). The Cancer PathCHART SMVL will be updated for C632, Scrotum, with the next release of the NAACCR Edits Metafile, currently scheduled for May 2024. Assign histology codes 8085 and 8086 for the sites listed in the Solid Tumor Rules histology tables. The codes 8085 and 8086 are applicable for a small group of sites according to the year they became valid for implementation as follows. Head and Neck Oropharynx, Base of Tongue, Tonsils, Adenoids (2022+) Other Sites Cervix (2021+) Anus (2023+) Vagina (2023+) Vulva (2023+) Penis (2024+) Scrotum (2024+) While ICD-O-3.2 and Cancer PathCHART list additional sites such as Accessory Sinuses, they have not yet been implemented in the U.S. |

20240079 | Reportability/Histology--Conjunctiva: Is low-grade conjunctival melanocytic intraepithelial lesion (LG-CMIL) with focal high-grade features of the conjunctiva (C690) reportable? If reportable, what histology should be assigned? |
Additional comments in this pathology report state "The entire case was sent in consultation to an ophthalmic pathologist. [Pathologist] assigns a conjunctival melanocytic intraepithelial neoplasia (C-MIN) score of 2-3 due to the upward pagetoid migration of small, dendritic melanocytes. A C-MIN score of 2-3 is between low-grade conjunctival melanocytic intraepithelial lesion (LG-CMIL; C-MIN 2) and high-grade conjunctival intraepithelial lesion (HG-CMIL; C-MIN 3). The older terminology for this lesion would be primary acquired melanosis (PAM) with mild to focally moderate atypia." This term does not appear in the SEER Program Coding and Staging Manual (SPCSM), Appendix E1 of the SPCSM, or Solid Tumor Rules (specifically rule H3) . |
Conjunctival melanocytic intraepithelial neoplasia (C-MIN) is reportable; therefore, low-grade conjunctival melanocytic intraepithelial lesion (LG-CMIL) with focal high-grade features of the conjunctiva (C690) is reportable, 8720/2. We will add this to a future edition of the SEER manual. |

20240065 | Solid Tumor Rules/Histology--Ovary: What is the histology code for an ovarian primary with a pathology report final diagnosis of “Small-Cell Carcinoma (Hypercalcemic Type), Large-Cell Variant” diagnosed in 2012 (using the Multiple Primaries H rules) and one diagnosed in 2024 (using the Solid Tumor Rules)? See Discussion. |
2012 Total abdominal hysterectomy - bilateral salpingo-oophorectomy Primary Site – Ovary, Right Histology - Small-Cell Carcinoma (Hypercalcemic Type), Large-Cell Variant 2024 Total abdominal hysterectomy - bilateral salpingo-oophorectomy Primary Site – Ovary, Left Histology - Small-Cell Carcinoma (Hypercalcemic Type), Large-Cell Variant |
Abstract this case as a single primary. Code as 8044/3 (small cell carcinoma, hypercalcemic type) listed in the Other Sites Solid Tumor Rules, Table 13. Small cell carcinoma, large cell variant, is a subtype of small cell carcinoma, hypercalcemic type. This table does not include all possible histologies. WHO Classification of Female Genital Tumors, 5th edition, states: Small cell carcinoma of the ovary, hypercalcemic type, is rare, accounting for < 1% of ovarian tumors. Small cell carcinomas, hypercalcemic type, are usually large, with a mean size of 15 cm (range: 6–26 cm). Large cells are present (in varying numbers) in half of these tumors, which are designated “small cell carcinoma, large cell subtype” if the large cells are predominant (which is rare). |

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. |

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. |
