Over-ride Hospital Sequence/Site 1988 1 CoC 1894-1894

Description
Some computer edits identify errors. Others indicate possible errors that require manual review for resolution. To eliminate the need to review the same cases repeatedly, over-ride flags have been developed to indicate that data in a record (or records) have been reviewed and, while unusual, are correct.

This over-ride is used with the following edits in the NAACCR Metafile of the EDITS software:
      Seq Num--Hosp, Primary Site, Morph ICDO2 (CoC)
      Seq Num--Hosp, Primary Site, Morph ICDO3 (CoC)

Rationale
Some edits check for code combinations that are possible, but quite rare. If the code combination generates an error message and review of the case indicates that the codes are correct for the case, then the over-ride flag is used to skip the edit in the future. See Chapter IV, Recommended Data Edits and Software Coordination of Standards.

Over-ride Flag as Used in the EDITS Software Package
Edits of the type Seq Num--Hosp, Primary Site, Morph differ in use of ICD-O-2 or ICD-O-3 morphology. They force review of multiple primary cancers when one of the primaries is coded to a site/morphology combination that could indicate a metastatic site rather than a primary site.
  1. If Sequence Number--Hospital indicates the person has had more than one primary, then any case with one of the following site/histology combinations requires review:
  2. If it turns out that the suspect tumor is a manifestation of one of the patient's other cancers, delete the metastatic or secondary case, re-sequence remaining cases, and correct the coding on the original case as necessary.
