21872-7

LOINC code 21872-7 identifies "Relationship between this hospital and cancer Dx". For a hospital registry, divides cases into two groups: analytic cases are those included in reports on patient treatment and outcomes; nonanalytic cases are those not included in such reports. Class of Case codes 0-2 identify cases that are analytic (i.e., cases that were first diagnosed and/or received all or part of their first course of treatment or had treatment planned at the reporting hospital). Class of Case codes 3-5, 7, 8, and 9 identify cases that are considered nonanalytic (i.e., were first diagnosed and received all of their first course of treatment at a facility other than the reporting institution, or were diagnosed at autopsy or by death certificate only). Class of Case 6 identifies cases that were first diagnosed and received their entire first course of treatment in the same staff physician's office. These cases were considered analytic for diagnosis dates January 1, 1998, through December 31, 1999. For diagnosis dates on or after January 1, 2000, these cases are considered nonanalytic. Class of Case can be used in conjunction with Type of Reporting Source [500]. Type of Reporting Source is designed to document the source of documents used to abstract the cancer being reported...
