III_3_8 Casefinding Source

III.3.8 Casefinding Source

This two-digit field indicates the source that identified the case.

Determine where the case was first identified, and enter the appropriate code. However, if a hospital and a non-hospital source identified the case independently of each other, enter the code for the non-hospital source (i.e., codes 30-95 have priority over codes 10-29).
If the case was first identified at a cancer reporting facility (codes 10-29), code the earliest source of identifying information.
If a death certificate, private pathology laboratory report, consultation only report from a hospital, or other report was used to identify a case that was then abstracted from a different source, enter the code for the source that first identified the case, not the source from which it was abstracted.
If the regional registry or CCR identifies a case and asks a reporting facility to abstract it, the regional registry or CCR must specify the appropriate code to be used in the field.
If a case was identified through the Death Clearance process at the regional registry, the hospital must use code 80 when abstracting the case.
