Inquiry Details

#1: ICD-O-3.2
#2: Subject matter expert. SINQ 20220032
Question:
Reportability/Histology--Ovary/Testis: Is serous borderline tumor-micropapillary variant (8460/2) of the ovary or testis reportable? If so, what dates are applicable to the reportability changes? See Discussion.
Discussion:
Serous borderline tumor–micropapillary variant (8460/2, C569) was included in the ICD-O-3 Behavior Code/term updates effective 1/1/2018 but marked as Not Reportable for 2018.
There have been multiple additional updates to the ICD-O but no further clarification as to the reportability of this histology. ICD-O-3.2 currently lists serous borderline tumor, micropapillary variant (C569) as 8460/2 with no mention of reportability and no information provided in Includes/Excludes.
SINQ 20220032 instructs capturing this histology as reportable when diagnosed 1/1/2021 or later and occurring in the testis. The answer indicates this is reportable due to the /2 behavior code in ICD-O-3.2, but it does not specify that it is limited to specific sites.
Is serous borderline tumor, micropapillary variant reportable for ovary? If so, what dates apply? Is serous borderline tumor, micropapillary variant of the testis diagnosed after 1/1/2021 reportable?
Answer:
Do not report serous borderline tumor–micropapillary variant of the ovary (8460/2, C569) as borderline ovarian tumors are not reportable. This applies to cases 2018 and later.
Do report serous borderline tumor–micropapillary variant of the testis as stated in SINQ 20220032. It is reportable for cases diagnosed Jan 1, 2021 and later.
