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.

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.

Assign histology as 9982/3 (myelodysplastic neoplasm with low blasts and SF3B1 mutation). This is a new term for 9982/3. WHO Classification of Hematolymphoid Tumors, 5th edition, defines myelodysplastic neoplasm (MDS) with low blasts and SF3B1 mutation (MDS-SF3B1) as a myeloid neoplasm with cytopenia and dysplasia characterized by SF3B1 mutation and often ring sideroblasts.

Do not report angiomyxoma. ICD-O-3.2 assigns 8841/0 to this benign tumor. This includes superficial and deep (aggressive) angiomyxoma.

Assign code 550 (Bladder, NOS excluding mucosa) to EOD Primary Site based on invasion into the bladder with no mention of mucosa. EOD Primary Tumor for cervix, Note 1, instructions are to use the extension information to code primary tumor in preference to a statement of FIGO stage when both are available. TNM staging is closely related to FIGO stage, and the surgical findings of bladder invasion NOS in this case should be used in preference to the statement of T4.

Abstract a single primary as 8272/3 (pituitary adenoma/PitNET) using the Malignant CNS and Peripheral Nerves Solid Tumor Rules, Rule M2, a single tumor is always a single tumor. Change the histology of the 2023 diagnosis to 8272/3. This scenario does not meet the criteria in the current rules for M5 in that it requires a resection as part of the criteria. Since the patient did not undergo resection for either diagnosis, the 2024 diagnosis may indicate recurrence or progression.

A diagnosis of pituitary adenoma only is still coded 8272/0 (this code is still valid). A diagnosis of pituitary adenoma/PitNET, PitNET, or pituitary neuroendorine tumor is coded 8272/3. Cabergoline is used to treat prolactinoma or high levels of prolactin but does not impact the PitNET.

Abstract as bone metastasis for the first two examples. Abstract as both bone and brain metastasis for the third and fourth examples in the respective Mets at Diagnosis fields based on the description provided.

The CPC ICD-O-3 Site Morphology Validation Lists (SMVLs) designate all tumor site-morphology combinations that are either valid or impossible as determined for the sites reviewed by the Cancer PathCHART initiative. These lists provide information on the Validity Status of specific tumor site and morphology combinations, similar to the way the ICD-O-3 SEER Site/Histology Validation List used to. However, the CPC SMVLs do not include information on the reportability of specific tumor site and morphology combinations. For tumor reportability, you will continue to use the Excel ICD-O-3.2 spreadsheets posted to the NAACCR ICD-O-3 Coding Updates website: https://www.naaccr.org/icdo3/, and the most recent SEER Manual and federal, state, local, and other standard setters' reportability requirements.

Assign code 8020/3 when the histologic type specifically includes the term of poorly differentiated, dedifferentiated, undifferentiated, or anaplastic undifferentiated carcinoma along with carcinoma as terms vary depending on the primary site. When the term poorly differentiated is included in the grade section only of the pathology report or only mentions poorly differentiated carcinoma without further substantiation from a pathology report as in examples 1 and 2, do not use code 8020/3.

The histology code 8020/3 and terms may be used for selected primary sites as included in the Solid Tumor Rules, WHO Classification of Tumors series (latest versions), and the Site/Morphology Validation List including

Nasal cavity

Nasopharynx

Salivary glands

Urinary sites

Colon, rectosigmoid, rectum

Esophagus

Stomach

Gallbladder and extrahepatic bile duct

Pancreas

Thyroid

Ovary

Uterine corpus

Vagina

Uterine cervix (also referred to as unclassifiable in WHO Classification of Female Genital Tumors, 5th ed.)

For sites other than those listed, if the diagnosis is poorly differentiated carcinoma, code 8010/3 and poorly differentiated in the grade field. 

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.
