Reportability/Behavior--Ovary: Is ovarian mucinous
borderline tumor with foci of multifocal intraepithelial carcinoma reportable?
Report ovarian mucinous borderline tumor with foci of
multifocal intraepithelial carcinoma. The foci of intraepithelial carcinoma
makes this reportable. See the list of synonyms for in situ in the SEER Manual,
Behavior Code data item.
Reportability/Histology--Soft Tissue: Is superficial CD34 positive fibroblastic tumor reportable and if so what histology code should be used? See Discussion.
Patient had a left thigh soft tissue mass excision on 7/24/24 and was diagnosed with superficial CD34 positive fibroblastic tumor. Margins were narrowly free of disease. Tumor size was 5.5 cm x 4.4 cm x 3.9 cm. The diagnosis was confirmed.
Do not report superficial CD34-positive fibroblastic tumor (8810/1) of the thigh.
WHO Classification of Soft Tissue and Bone Tumors, 5th ed., defines superficial CD34-positive fibroblastic tumor as a distinctive low-grade neoplasm of the skin and subcutis, most frequently occurring in the lower extremities, especially thigh, followed by arm, buttock, shoulder, and rarely, vulva.
Reportability--Head & Neck: Are high-grade squamous dysplasia / “severe” squamous dysplasia or glandular intraepithelial neoplasia reportable for all Head & Neck subsites? If so, what year did they become reportable? In reviewing SINQ 20240003, 20230047, and 20230046, it appears that at least the larynx, mandible, and tongue have been reportable since 2021. However, 8077/2 and 8148/2 histology codes are not included in the Solid Tumor Rules (STRs) (2025 update) for Head and Neck, either in Tables 1-9 or the H Rules.
High grade squamous dysplasia (8077/2) is reportable for head and neck sites for cases diagnosed as of 01/01/2021. High grade glandular intraepithelial neoplasia / glandular intraepithelial neoplasia grade III (8148/2) and high grade squamous intraepithelial neoplasia / squamous intraepithelial neoplasia grade III (8077/2) are reportable for head and neck sites for cases diagnosed as of 01/01/2001. Refer to other standard setters’ criteria for reportability as appropriate.
Immunotherapy/Other
Therapy--Heme & Lymphoid Neoplasms: Is the elimination of immunosuppression
treatment coded as other treatment? An example is when a post-transplant
patient develops a malignant myeloproliferative neoplasm that subsides when
immunosuppression drugs are stopped.
Do not code as a treatment. Record the cessation of
immunosuppressive drug treatment in text to explain the patient’s change in
disease status.
Solid Tumor Rules/Histology/Behavior--Brain and CNS: How
are histology and behavior coded when the Integrated Diagnosis is
"Meningioma, WHO Grade 2," and the Histological Classification is
"Meningioma with elevated mitotic activity, hypercellularity, necrosis,
and sheeting architecture?" See Discussion.
We are increasingly seeing pathologists use this
terminology to describe WHO G2 meningiomas, but the histology term
"Atypical meningioma" is not being used, and a more specific "Histological
Classification" of other WHO Grade 2 meningiomas (i.e., chordoid or clear
cell meningioma) is not given. Can the combination of meningioma, WHO Grade 2
plus the histological classification listing multiple features of an atypical
meningioma be used to code morphology to 9539/1? Or is this just a meningioma,
NOS 9530/0 despite the WHO Grade 2 classification?
Code meningioma, NOS (9530/0) based on the integrated diagnosis
and histological classification. WHO Classification of Central Nervous System Tumors,
5th edition, states that brain invasion is a criterion for the
diagnosis of CNS WHO grade 2 meningioma, and there is no statement of brain
invasion, atypical meningioma, or other WHO grade 2 lesions. WHO has not
proposed behavior codes based on WHO grade alone.
Race/Spanish Surname or Origin: How are Race 1 and Spanish
Surname or Origin coded for the following race/ethnicity statements: "INDIGENOUS-LATINO/A
OR INDIGENOUS-LATINX" and "FIRST NATIONS"? See Discussion.
One of the largest hospital systems in our area includes "INDIGENOUS-LATINO/A OR INDIGENOUS-LATINX" and "FIRST NATIONS" as dropdown items for patients to self-select for race/ethnicity. This hospital system serves 51 hospitals and 1,000 clinics across Alaska, California, Montana, New Mexico, Oregon, Texas, and Washington. If "INDIGENOUS-LATINO/A OR INDIGENOUS-LATINX" is the only item selected with no additional text info available, how should Race 1 and Spanish Surname or Origin be coded? If "FIRST NATIONS" is the only item selected without additional text info available, should Race 1 be coded as 03?
Assign code 01 (White) for Race 1 when described as Indigenous-Latino/a or Indigenous-Latinx. Indigenous-Latinx is an umbrella term for Indigenous migrants to the United States from Latin America including South and Central America, the Caribbean, and Mexico (for example, Maya, Mixteco, Purépecha, Taino, Zapoteco, etc.). Latin America is listed in Appendix D of the 2025 SEER Manual as White.
Assign code 6 (Spanish, NOS; Hispanic, NOS; Latino, NOS) for Spanish Surname or Origin for Indigenous-Latino/a or Indigenous-Latinx in the absence of more specific information. Code 6 description includes the statement, There is evidence, other than surname or birth surname (maiden name), that the person is Hispanic but he/she cannot be assigned to any of the categories 1-5.
Assign code 03 (American Indian or Alaska Native) when described as First Nations. First Nations usually refers to Indigenous peoples for ethnic groups who are the original or earliest known inhabitants of an area. The term ‘First Nations’ can be applied to individuals, but technically refers only to those who have Indian status under Canadian law as part of a recognized community. Within Canada, the term First Nations is generally used for Indigenous peoples other than Inuit and Métis. Outside Canada, the term can refer to Indigenous Australians, U.S. tribes within the Pacific Northwest, as well as supporters of the Cascadian independence movement.
