Site/Lat/SeqNo Override (IR09)

Given two records for the same person coded with the same three-digit histology code and - in cases where the sites are paired organs, the same known laterality (see Table 2) - there must be no ambiguity of primary site between specified and NOS. That is, if the site code in one of the records appears in the left column of Table 1 below, then the site in the other records must not occur in the same line on the right side of the table. This edit is performed only for invasive diagnoses (Behavior = 3).

(Where AA represents any two-digit number except 16, 53, 71; BB represents any two-digit number and x represents any one-digit number.)
