MESSAGE

1. IF 1085: MerkelCell schemas: If CS Extension = [value], then CS Site-Specific Factor18 must = 000, 010, or 999

specification

The purpose of this edit is to verify that CS Extension and CS Site-Specific Factor 18 (isolated tumor cells in regional lymph nodes) are coded consistently for non-invasive cases coded using the MerkelCellPenis, MerkelCellScrotum, MerkelCellSkin, and MerkelCellVulva schemas that are originally coded using CSv02.05 or higher.

This edit is skipped if any of the following conditions are true:

1.    CS Version Input Original is less than 020500

2.    CS Extension is blank

3.    Site-Specific Factor 18 is blank or 988

4.    Behavior Code ICD-O-3 = 0 (benign) or 1 (borderline)

This edit first determines the correct CS schema by doing a function call to the CS Dynamic Link Library (dll).  The function call passes Primary Site, Histologic Type ICD-O-3, and CS Site-Specific Factor25 (schema discriminator) to the dll and the CS schema name is returned.

If schema is MerkelCellPenis, MerkelCellScrotum, MerkelCellSkin, or MerkelCellVulva:

1. If CS Extension = 000 (In situ, intraepidermal, intraepithelial, noninvasive), then CS Site-Specific Factor18 (isolated tumor cells in regional lymph nodes) must = 000 (regional lymph nodes negative on H and E, no IHC), 010 (regional lymph nodes negative on H and E, IHC done and ITCs not present) or 999 (unknown).
