SEER Inquiry System - Search

A tumor that is non-reportable based on the pathology report diagnosis should not be accessioned if later clinician statements mistakenly refer to it as a reportable tumor. The exception in the 2007 SEER manual on page 3 is intended to allow the registrar to accession a case when the clinician actually disagrees with the pathology report and clinically diagnoses a reportable tumor.

Accession the case and code Diagnostic Confirmation as 8 [clinical diagnosis only]. Accession a case with negative pathology when the clinician is aware of the negative pathology and continues to refer to the case as malignant.

High-grade anal squamous intraepithelial neoplasia (ASIN-H) is synonynous with anal intraepithelial neoplasia, grade III (AIN III).

For cases diagnosed 2018 and later

Differentiated penile intraepithelial neoplasia (differentiated PeIN), is reportable (8071/2).

Please note: Penile intraepithelial neoplasia, grade 3 (PeIN 3) is also reportable to SEER (C600-C609, 8077/2).

For cases diagnosed 2021 and later

VIN II-III is reportable based on ICD-O-3.2 which lists squamous intraepithelial neoplasia, grade II as 8077/2 making it reportable. Also see SINQ 20120094.

This neoplasm is reportable because it is malignant as proven by the lymph node metastases. Code the behavior as malignant (/3) when there are lymph node metastases.

Typically, the final diagnosis of the reviewing pathologist is the one used to determine whether the case is SEER reportable. If two or more reviewing pathologists disagree as to whether the case should be reportable, determine reportability based on the following priority order:

1) If the patient is treated for cancer, the case is reportable.

2) If the patient is not treated for cancer, use the amended diagnosis on the original pathology report if the hospital pathologist used the reviewing pathologists' opinions in establishing his new diagnosis.

3) If there is not an amended diagnosis for the original hospital pathology report, use the clinician's opinion regarding what the diagnosis is to determine whether the case is reportable.

The following cancer cases are reportable unless there is information to the contrary.

–Liver cases with an LI-RADS category LR-4 (reportable since 2021) or LR-5 (reportable since 2016)

–Prostate cases with a PI-RADS category 4 or 5 (reportable since 2017)

The following are not reportable without additional information.

–Breast cases designated BI-RADS 4, 4A, 4B, 4C or BI-RADS 5

–Lung cases designated Lung-RADS 4A," 4B, or 4X

–Liver cases based only on an LI-RADS category of LR-3

–Colon cases with only C-RADS information (C-RADS category C4 is not reportable by itself)

–Head and Neck cases with only NI-RADS information (NI-RADS category 3 is not reportable by itself)

–Ovarian or fallopian tube cases with only O-RADS information (none of the O-RADS categories are reportable without additional information)

–Thyroid cases with only TI-RADS information (none of the TI-RADS categories are reportable without additional information)

For cases diagnosed 2021 or later

Lobular neoplasia (LN II and LN III) and lobular intraepithelial neoplasia (LIN II and LIN III) are reportable and coded 8520/2.

According to the editors of ICD-O-3, lobular neoplasia grade 2 is not equivalent to LCIS. It is not a reportable term. Lobular neoplasia and lobular intraepithelial neoplasia are equivalent terms having a three grade system. Only LN/LIN grade 3 would be reportable since those terms are analogous to ductal intraepithelial neoplasia grade 3.
